Limitations of Use : Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration, and persist over the course of therapy [see Warnings and Precautions (5.2) ] , reserve opioid analgesics, including hydromorphone hydrochloride injection for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.
Hydromorphone hydrochloride is an opioid agonist indicated for the management of pain severe enough to require an opioid analgesic and for which alternate treatments are inadequate. ( 1 ) Limitations of Use : Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration and persist over the course of therapy, reserve opioid analgesics, including hydromorphone hydrochloride injection, for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.
( 1 , 5.1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Hydromorphone Hydrochloride Injection should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. ( 2.1 ) Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Reserve titration to higher doses of Hydromorphone Hydrochloride Injection for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks.
( 2.1 , 5 ) Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available. ( 2.1 ) Initiate the dosing regimen for each patient individually, taking into account the patient’s underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse.
( 2.1 , 5.1 ) Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with Hydromorphone Hydrochloride Injection. Consider this risk when selecting an initial dose and when making dose adjustments. ( 2.1 , 5.2 ) I nitia l Dosage: - Intramuscular or Subcutaneous Use : The usual starting dose is 1 mg to 2 mg every 2 to 3 hours as necessary.
( 2.2 ) - Intravenous Use : The usual starting dose is 0.2 mg to 1 mg every 2 to 3 hours. The injection should be given slowly , over at least 2 to 3 minutes. ( 2.2 ) Hepatic Impairment : Initiate treatment with one-fourth to one-half the usual starting dose, depending on degree of hepatic impairment.
( 2.3 ) Renal Impairment: Initiate treatment with one-fourth to one-half the usual starting dose, depending on degree of renal impairment. ( 2.4 ) Periodically reassess patients receiving hydromorphone hydrochloride injection to evaluate the continued need for opioid analgesics to maintain pain control, for the signs of symptoms of adverse reactions, and for the development of addiction, abuse, or misuse. ( 2.5 ) Do not rapidly reduce or abruptly discontinue hydromorphone hydrochloride injection in a physically dependent patient.
( 2.6 , 5.12 )
2.1Important Dosage and Administration Instructions Hydromorphone Hydrochloride Injection should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals [see Warnings and Precautions (5) ]. Because the risk of overdose increases as opioid doses increase, reserve titration to higher doses of Hydromorphone Hydrochloride Injection for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks.
Many acute pain conditions (e.g., the pain that occurs with a number of surgical procedures or acute musculoskeletal injuries) require no more than a few days of an opioid analgesic. Clinical guidelines on opioid prescribing for some acute pain conditions are available. There is variability in the opioid analgesic dose and duration needed to adequately manage pain due both to the cause of pain and to individual patient factors.
Initiate the dosing regimen for each patient individually, taking into account the patient’s underlying cause and severity of pain, prior analgesic treatment and response, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5.1) ]. Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with Hydromorphone Hydrochloride Injection. Consider this risk when selecting an initial dose and when making dose adjustments [see… [Excerpted — this section continues on DailyMed.]

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Opioid-Induced Hyperalgesia and Allodynia: Opioid-Induced Hyperalgesia (OIH) occurs when opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain. If OIH is suspected, carefully consider appropriately decreasing the dose of the current opioid analgesic, or opioid rotation. ( 5.5 ) Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients : Monitor closely, particularly during initiation and titration.
( 5.6 ) Adrenal Insufficiency : If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. ( 5.7 ) Severe Hypotension : Monitor during dosage initiation and titration. Avoid use of hydromorphone hydrochloride injection in patients with circulatory shock.
( 5.8 ) Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness : Monitor for sedation and respiratory depression. Avoid use of hydromorphone hydrochloride injection in patients with impaired consciousness or coma. ( 5.9 ) Hydromorphone hydrochloride injection contains sodium metabisulfite.
There is a risk of anaphylactic symptoms and life-threatening asthmatic episodes in susceptible people. ( 5.14 ) 5.1. Addiction, Abuse, and Misuse Hydromorphone hydrochloride injection contains hydromorphone, a Schedule II controlled substance.
As an opioid, hydromorphone hydrochloride injection exposes users to the risks of addiction, abuse, and misuse [see Drug Abuse and Dependence (9) ]. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed hydromorphone hydrochloride injection. Addiction can occur at recommended dosages and if the drug is misused or abused.
The risk of opoid-related overdose or overdose-related death is increased with higher opioid doses, and this risk persists over the course of therapy. In postmarketing studies, addiction, abuse, misuse, and fatal and non-fatal opioid overdose were observed in patients with longterm opioid use [see Adverse Reactions (6) ]. Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing hydromorphone hydrochloride injection, and monitor all patients receiving hydromorphone hydrochloride injection for the development of these behaviors and conditions.
Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as hydromorphone hydrochloride injection, but use in such patients necessitates intensive counseling about the risks and proper use of hydromorphone hydrochloride injection along with intensive monitoring for signs of addiction, abuse, and misuse.
Opioids are sought for nonmedical use and are subject to diversion from legitimate prescribed use. Consider these risks when prescribing or dispensing hydromorphone hydrochloride injection. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity.
Contact local state professional licensing board or state- controlled substances authority for information on how to prevent and detect abuse or diversion of this product.
5.2Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid overdose reversal agent (e.g., naloxone, nalmefene), depending on the patient’s clinical status [see Overdosage (10) ].

🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following serious adverse reactions are described, or described in greater detail, in other sections: Addiction, Abuse, and Misuse [see Warnings and Precautions (5.1) ] Life-Threatening Respiratory Depression [see Warnings and Precautions (5.2) ] Interactions with Benzodiazepines and Other CNS Depressants [see Warnings and Precautions (5.3) ] Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.4)] Opioid-Induced Hyperalgesia and Allodynia [see Warnings and Precautions (5.5) ] Adrenal Insufficiency [see Warnings and Precautions (5.7) ] Severe Hypotension [see Warnings and Precautions (5.8) ] Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.10) ] Seizures [see Warnings and Precautions (5.11) ] Withdrawal [see Warnings and Precautions (5.12)] The following adverse reactions associated with the use of hydromorphone were identified in clinical studies or postmarketing reports.
Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Serious adverse reactions associated with hydromorphone hydrochloride injection include respiratory depression and apnea and, to a lesser degree, circulatory depression, respiratory arrest, shock, and cardiac arrest. The most common adverse effects are lightheadedness, dizziness, sedation, nausea, vomiting, sweating, flushing, dysphoria, euphoria, dry mouth, and pruritus.
These effects seem to be more prominent in ambulatory patients and in those not experiencing severe pain. Less Frequently Observed Adverse Reactions Cardiac disorders: tachycardia, bradycardia, palpitations Eye disorders: vision blurred, diplopia, miosis, visual impairment Gastrointestinal disorders: constipation, ileus, diarrhea, abdominal pain General disorders and administration site conditions: weakness, feeling abnormal , chills, injection site urticaria, fatigue, injection site reactions, peripheral edema Hepatobiliary disorders: biliary colic Immune system disorders: anaphylactic reactions, hypersensitivity reactions Investigations: hepatic enzymes increased Metabolism and nutrition disorders: decreased appetite Musculoskeletal and connective tissue disorders: muscle rigidity Nervous system disorders: headache, tremor, paraesthesia, nystagmus, increased intracranial pressure, syncope, taste alteration , involuntary muscle contractions, presyncope, convulsion, drowsiness, dyskinesia, hyperalgesia, lethargy, myoclonus, somnolence Psychiatric disorders: agitation, mood altered, nervousness, anxiety , depression, hallucination, disorientation, insomnia, abnormal dreams Renal and urinary disorders: urinary retention, urinary hesitation, antidiuretic effects Reproductive system and breast disorders: erectile dysfunction Respiratory, thoracic, and mediastinal disorders: bronchospasm, laryngospasm, dyspnea, oropharyngeal swelling Skin and subcutaneous tissue disorders: injection site pain, urticaria, rash, hyperhidrosis Vascular disorders: flushing, hypotension, hypertension Serotonin syndrome : Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.

7 DRUG INTERACTIONS Table 1 includes clinically significant drug interactions with hydromorphone hydrochloride injection. TABLE 1 Clinically Significant Drug Interactions with Hydromorphone Hydrochloride Injection B enzodiazepines and other Central Nervous System Depressants (CNS) C linical Impact: Due to additive pharmacologic effect, the concomitant use of benzodiazepines and other CNS depressants, including alcohol, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death. [see Warnings and Precautions (5.3) ].
In tervention: Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients closely for signs of respiratory depression and sedation [see Warnings and Precautions (5.3) ].
E xamples: Benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids (gabapentin or pregabalin), other opioids, alcohol. Serotonergic Drugs C linical Impact: The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome. In tervention: If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation and dose adjustment.
Discontinue hydromorphone hydrochloride injection if serotonin syndrome is suspected. E xamples: Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that effect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue).
M o noamine Oxidase Inhibitors (MAOIs) C linical Impact: MAOI interactions with opioids may manifest as serotonin syndrome or opioid toxicity (e.g., respiratory depression, coma) [see WARNINGS AND PRECAUTIONS (5.2) ] . If urgent use of an opioid is necessary, use test doses and frequent titration of small doses to treat pain while closely monitoring blood pressure and signs and symptoms of CNS and respiratory depression. In tervention: The use of hydromorphone hydrochloride injection is not recommended for patients taking MAOIs or within 14 days of stopping such treatment.
If urgent use of an opioid is necessary, use test doses and frequent titration of small doses while closely monitoring blood pressure and signs and symptoms of CNS and respiratory depression. E xamples: phenelzine, tranylcypromine, linezolid M ixed Agonist/Antagonist and Partial Agonist Opioid Analgesics C linical Impact: May reduce the analgesic effect of hydromorphone hydrochloride injection and/or precipitate withdrawal syndrome. In tervention: Avoid concomitant use.
E xamples: butorphanol, nalbuphine, pentazocine, buprenorphine M uscle Relaxants C linical Impact: Hydromorphone may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression. In tervention: Monitor patients for signs of respiratory depression that may be greater than otherwise expected and decrease the dosage of hydromorphone hydrochloride injection and/or the muscle relaxant as necessary. Examples: cyclobenzaprine, metaxalone Diuretics C linical Impact: Opioids can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone.
In tervention: Monitor patients for signs of diminished diuresis and/or effects on blood pressure and increase the dosage of the diuretic as needed. Anticholinergic Drugs C linical Impact: The concomitant use of anticholinergic drugs may increase risk of urinary retention and/or severe constipation, which may lead to paralytic ileus. In tervention: Monitor patients for signs of urinary retention or reduced g… [Excerpted — this section continues on DailyMed.]
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy : May cause fetal harm. ( 8.1 )
8.1Pregnancy Risk Summary Use of opioid analgesics for an extended period of time during pregnancy may cause neonatal opioid withdrawal syndrome [see Warnings and Precautions (5.5 ]. There are no available data with hydromorphone hydrochloride injection in pregnant women to inform a drug-associated risk for major birth defects and miscarriage or adverse maternal outcomes. There are adverse outcomes reported with fetal exposure to opioid analgesics (see Clinical Considerations) .
In animal reproduction studies, reduced postnatal survival of pups, and decreased body weight were noted following oral treatment of pregnant rats with hydromorphone during gestation and through lactation at doses 0.8 times the human daily dose of 24 mg/day (HDD), respectively. In published studies, neural tube defects were noted following subcutaneous injection of hydromorphone to pregnant hamsters at doses 6.4 times the HDD and soft tissue and skeletal abnormalities were noted following subcutaneous continuous infusion of 3 times the HDD to pregnant mice.
No malformations were noted at 4 or 40.5 times the HDD in pregnant rats or rabbits, respectively [ see Data ]. Based on animal data, advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Use of opioid analgesics for an extended period of time during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth.
Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea, and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [see Warnings and Precautions (5.5) ].
Labor or Delivery Opioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. An opioid overdose reversal agent, such as naloxone or nalmefene, must be available for reversal of opioid-induced respiratory depression in the neonate. Hydromorphone hydrochloride injection is not recommended for use in pregnant women during or immediately prior to labor, when other analgesic techniques are more appropriate.
Opioid analgesics, including hydromorphone hydrochloride injection, can prolong labor through actions which temporarily reduce the strength, duration, and frequency of uterine contractions. However, this effect is not consistent and may be offset by an increased rate of cervical dilation, which tends to shorten labor. Monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression.
Data Animal Data Pregnant rats were treated with hydromorphone hydrochloride from Gestation Day 6 to 17 via oral gavage doses of 1, 5, or 10 mg/kg/day (0.4, 2, or 4 times the HDD of 24 mg based on body surface area, respectively). Maternal toxicity was noted in all treatment groups (reduced food consumption and body weights in the two highest dose groups). There was no evidence of malformations or embryotoxicity reported.

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of hydromorphone hydrochloride injection in pediatric patients has not been established.
🧓 Geriatric Use ▾
8.5Geriatric Use Elderly patients (aged 65 years or older) may have increased sensitivity to hydromorphone. In general, use caution when selecting a dosage for an elderly patient, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy. Respiratory depression is the chief risk for elderly patients treated with opioids, and has occurred after large initial doses were administered to patients who were not opioid-tolerant or when opioids were co-administered with other agents that depress respiration.
Titrate the dosage of hydromorphone hydrochloride injection slowly in geriatric patients and monitor closely for signs of central nervous system and respiratory depression [see Warnings and Precautions (5.7) ]. Hydromorphone is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.
🆘 Overdosage ▾
10 OVERDOSAGE Clinical Presentation Acute overdose with hydromorphone can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis, rather than miosis, may be seen with hypoxia in overdose situations [see Clinical Pharmacology (12.2) ] . Toxic leukoencephalopathy has been reported after opioid overdose and can present hours, days, or weeks after apparent recovery from the initial intoxication.
Treatment of Overdose In case of overdose, priorities are the reestablishment of a patent airway and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support techniques.
For clinically significant respiratory or circulatory depression secondary to hydromorphone overdose, administer an opioid overdose reversal agent such as naloxone or nalmefene. Because the duration of opioid reversal is expected to be less than the duration of hydromorphone in hydromorphone hydrochloride injection, carefully monitor the patient until spontaneous respiration is reliably reestablished. If the response to an opioid overdose reversal agent is suboptimal or only brief in nature, administer additional reversal agent as directed by the product’s prescribing information.
In an individual physically dependent on opioids, administration of the recommended usual dosage of the opioid overdose reversal will precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the reversal agent administered. If a decision is made to treat serious respiratory depression in the physically dependent patient, administration of the reversal agent should be initiated with care and by titration with smaller than usual doses of the reversal agent.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Hydromorphone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of hydromorphone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with morphine.
Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression. The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug.
12.2Pharmacodynamics Effects on the Central Nervous System Hydromorphone produces respiratory depression by direct effect on brain stem respiratory centers. The respiratory depression involves a reduction in the responsiveness of the brain stem respiratory centers to both increases in carbon dioxide tension and electrical stimulation. Hydromorphone causes miosis, even in total darkness.
Pinpoint pupils are a sign of opioid overdose but are not pathognomonic (e.g., pontine lesions of hemorrhagic or ischemic origin may produce similar findings). Marked mydriasis rather than miosis may be seen due to hypoxia in overdose situations. Effects on the Gastrointestinal Tract and Other Smooth Muscle Hydromorphone causes a reduction in motility associated with an increase in smooth muscle tone in the antrum of the stomach and duodenum.
Digestion of food in the small intestine is delayed and propulsive contractions are decreased. Propulsive peristaltic waves in the colon are decreased, while tone may be increased to the point of spasm, resulting in constipation. Other opioid-induced effects may include a reduction in biliary and pancreatic secretions, spasm of sphincter of Oddi, transient elevations in serum amylase, and opioid-induced esophageal dysfunction (OIED).
Effects on the Cardiovascular System Hydromorphone produces peripheral vasodilation which may result in orthostatic hypotension or syncope, manifestations of histamine release and/or peripheral vasodilation may include pruritus, flushing, red eyes, and sweating and/or orthostatic hypotension. Effects on the Endocrine System Opioids inhibit the secretion of adrenocorticotropic hormone (ACTH), cortisol, and luteinizing hormone (LH) in humans [see Adverse Reactions (6) ] . They also stimulate prolactin, growth hormone (GH) secretion, and pancreatic secretion of insulin and glucagon.
Use of opioids for an extended period of time may influence the hypothalamic-pituitary-gonadal axis, leading to androgen deficiency that may manifest as low libido, impotence, erectile dysfunction, amenorrhea, or infertility. The causal role of opioids in the clinical syndrome of hypogonadism is unknown because the various medical, physical, lifestyle, and psychological stressors that may influence gonadal hormone levels have not been adequately controlled for in studies conducted to date [see Adverse Reactions (6) ] .
Effects on the Immune System Opioids have been shown to have a variety of effects on components of the immune system in in vitro and animal models. The clinical significance of these findings is unknown. Overall, the effects of opioids appear to be modestly immunosuppressive.
Concentration–Efficacy Relationships The minimum effective analgesic concentration will vary widely among patients, especially among patients who have been previously treated with opioid agonists . The minimum effective analgesic concentration of hydromorphone for any individual patient may increase over time due to an increase in pain, the development of a new pain syndrome, and/or the development of analgesic tolerance [see Dosage and Administration (2.1 , 2.2) ] . Concentration–Adverse Reaction Relationships There is a relationship between increa… [Excerpted — this section continues on DailyMed.]

8.3Females and Males of Reproductive Potential Infertility Use of opioids for an extended period of time may cause reduced fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible [see Adverse Reactions (6) , Clinical Pharmacology (12.2) , Nonclinical Toxicology (13.1)] .
🧬 Pharmacokinetics ▾
12.3Pharmacokinetics Distribution At therapeutic plasma levels, hydromorphone is approximately 8-19% bound to plasma proteins. After an intravenous bolus dose, the steady state of volume of distribution [mean (%CV)] is 302.9 (32%) liters. Elimination The systemic clearance is approximately 1.96 (20%) liters/minute.
The terminal elimination half-life of hydromorphone after an intravenous dose is about 2.3 hours. Metabolism Hydromorphone is extensively metabolized via glucuronidation in the liver, with greater than 95% of the dose metabolized to hydromorphone-3-glucuronide along with minor amounts of 6-hydroxy reduction metabolites. Excretion Only a small amount of the hydromorphone dose is excreted unchanged in the urine.
Most of the dose is excreted as hydromorphone-3-glucuronide along with minor amounts of 6-hydroxy reduction metabolites. Special Populations Hepatic Impairment After oral administration of hydromorphone at a single 4 mg dose (2 mg hydromorphone immediate-release tablets), mean exposure to hydromorphone (C max and AUC ∞ ) is increased 4-fold in patients with moderate (Child-Pugh Group B) hepatic impairment compared with subjects with normal hepatic function. Patients with moderate hepatic impairment should be started at one-fourth to one-half the recommended starting dose and closely monitored during dose titration.
The pharmacokinetics of hydromorphone in patients with severe hepatic impairment has not been studied. A further increase in C max and AUC of hydromorphone in this group is expected and should be taken into consideration when selecting a starting dose [see Use in Specific Populations (8.6) ] . Renal Impairment The pharmacokinetics of hydromorphone following an oral administration of hydromorphone at a single 4 mg dose (2 mg hydromorphone immediate-release tablets) are affected by renal impairment.
Mean exposure to hydromorphone (C max and AUC 0-∞ ) is increased by 2-fold in patients with moderate (CLcr = 40 - 60 mL/min) renal impairment and increased by 4-fold in patients with severe (CLcr < 30 mL/min) renal impairment compared with normal subjects (CLcr > 80 mL/min). In addition, in patients with severe renal impairment, hydromorphone appeared to be more slowly eliminated with a longer terminal elimination half-life (40 hr) compared to patients with normal renal function (15 hr). Start patients with renal impairment on one-fourth to one-half the usual starting dose depending on the degree of impairment.
Patients with renal impairment should be closely monitored during dose titration [see Use in Specific Populations (8.7) ]. Geriatric Population In the geriatric population, age has no effect on the pharmacokinetics of hydromorphone. Sex Sex has little effect on the pharmacokinetics of hydromorphone.
Females appear to have a higher C max (25%) than males with comparable AUC0-24 values. The difference observed in C max may not be clinically relevant.

Concentration–Adverse Reaction Relationships There is a relationship between increasing hydromorphone plasma concentration and increasing frequency of dose-related opioid adverse reactions such as nausea, vomiting, CNS effects, and respiratory depression.
In opioid-tolerant patients, the situation may be altered by the development of tolerance to opioid-related adverse reactions [see Dosage and Administration (2.1 , 2.2) ].
🔒 Drug Abuse and Dependence ▾
9 DRUG ABUSE AND DEPENDENCE
9.1Controlled Substance Hydromorphone hydrochloride injection contains hydromorphone, which is a Schedule II controlled substance.
9.2Abuse Hydromorphone hydrochloride injection contains hydromorphone, a substance with a high potential for misuse and abuse, which can lead to the development of substance use disorder, including addiction. [see Warnings and Precautions (5.1)] . Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a healthcare provider or for whom it was not prescribed. Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects.
Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence. Misuse and abuse of Hydromorphone Hydrochloride Injection increases risk of overdose, which may lead to central nervous system and respiratory depression, hypotension, seizures, and death.
The risk is increased with concurrent abuse of Hydromorphone Hydrochloride Injection with alcohol and/or other CNS depressants. Abuse of and addiction to opioids in some individuals may not be accompanied by concurrent tolerance and symptoms of physical dependence. In addition, abuse of opioids can occur in the absence of addiction.
All patients treated with opioids require careful and frequent reevaluation for signs of misuse, abuse, and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use. Patients at high risk of Hydromorphone Hydrochloride Injection abuse include those with a history of prolonged use of any opioid, including products containing hydromorphone, those with a history of drug or alcohol abuse or those who use Hydromorphone Hydrochloride Injection in combination with other abused drugs. “Drug-seeking” behavior is very common in persons with substance use disorders.
Drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing or referral, repeated “loss” of prescriptions, tampering with prescriptions, and reluctance to provide prior medical records or contact information for other treating healthcare provider(s). “Doctor shopping” (visiting multiple prescribers to obtain additional prescriptions) is common among people who abuse drugs and people with substance use disorder. Preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with inadequate pain control.
Hydromorphone hydrochloride injection, like other opioids, can be diverted for nonmedical use into illicit channels of distribution. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests as required by state and federal law, is strongly advised. Proper assessment of the patient, proper prescribing practices, periodic reevaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.
Risks Specific to Abuse of Hydromorphone Hydrochloride Injection Abuse of hydromorphone hydrochloride injection poses a risk of overdose and death. The risk is increased with concurrent use of hydromorphone hydrochloride injection with alcohol and/or other CNS depressants. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.
9.3Dependence Both tolerance and physical dependence can develop during use of opioid therapy. Tolerance is a physiological state characterized by a reduced response to a drug after repeated administration (i.e., a higher dose of a drug is required to produce the same effect that was once obtained… [Excerpted — this section continues on DailyMed.]
