Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Promethazine Hydrochloride Oral Solution should not be used in pediatric patients less than 2 years of age because of the potential for fatal respiratory depression. Postmarketing cases of respiratory depression, including fatalities, have been reported with use of promethazine in pediatric patients less than 2 years of age. A wide range of weight-based doses of promethazine have resulted in respiratory depression in these patients.

Caution should be exercised when administering promethazine to pediatric patients 2 years of age and older. It is recommended that the lowest effective dose of promethazine be used in pediatric patients 2 years of age and older and concomitant administration of other drugs with respiratory depressant effects be avoided.

🎯 Indications and Usage 134 words ▾

Antiemetic therapy in postoperative patients.

⏱️ Dosage and Administration ~3 min read ▾

DOSAGE AND ADMINISTRATION It is important that Promethazine Hydrochloride Syrup (Promethazine Hydrochloride Oral Solution, USP) is measured with an accurate measuring device (see PRECAUTIONS-Information for Patients ). A household teaspoon is not an accurate measuring device and could lead to overdosage, especially when half a teaspoon is to be measured. It is strongly recommended that an accurate measuring device be used.

A pharmacist can provide an appropriate device and can provide instructions for measuring the correct dose. Promethazine HCl Oral Solution is contraindicated for children under 2 years of age (see WARNINGS – Boxed Warning and Use in Pediatric Patients ). Allergy The average oral dose is 25 mg taken before retiring; however, 12.5 mg may be taken before meals and on retiring, if necessary.

Single 25 mg doses at bedtime or 6.25 to 12.5 mg taken three times daily will usually suffice. After initiation of treatment in children or adults, dosage should be adjusted to the smallest amount adequate to relieve symptoms. The administration of promethazine HCl in 25 mg doses will control minor transfusion reactions of an allergic nature.

Motion Sickness The average adult dose is 25 mg taken twice daily. The initial dose should be taken one-half to one hour before anticipated travel and be repeated 8 to 12 hours later, if necessary. On succeeding days of travel, it is recommended that 25 mg be taken on arising and again before the evening meal.

For children, 12.5 to 25 mg, twice daily, may be administered. Nausea and Vomiting Antiemetics should not be used in vomiting of unknown etiology in children and adolescents (see WARNINGS- Use in Pediatric Patients ). The average effective dose of Promethazine HCl Oral Solution for the active therapy of nausea and vomiting in children or adults is 25 mg.

When oral medication cannot be tolerated, the dose should be given parenterally (cf. Promethazine Hydrochloride Injection) or by rectal suppository. 12.5 to 25 mg doses may be repeated, as necessary, at 4 to 6 hour intervals.

For nausea and vomiting in children, the usual dose is 0.5 mg per pound of body weight, and the dose should be adjusted to the age and weight of the patient and the severity of the condition being treated. For prophylaxis of nausea and vomiting, as during surgery and the postoperative period, the average dose is 25 mg repeated at 4 to 6 hour intervals, as necessary. Sedation This product relieves apprehension and induces a quiet sleep from which the patient can be easily aroused.

Administration of 12.5 to 25 mg Promethazine HCl Oral Solution by the oral route at bedtime will provide sedation in children. Adults usually require 25 to 50 mg for nighttime, presurgical, or obstetrical sedation. Pre- and Postoperative Use Promethazine HCl Oral Solution in 12.5 to 25 mg doses for children and 50 mg doses for adults the night before surgery relieves apprehension and produces a quiet sleep.

For preoperative medication children require doses of 0.5 mg per pound of body weight in combination with an appropriately reduced dose of narcotic or barbiturate and the appropriate dose of an atropine-like drug. Usual adult dosage is 50 mg Promethazine HCl Oral Solution with an appropriately reduced dose of narcotic or barbiturate and the required amount of a belladonna alkaloid. Postoperative sedation and adjunctive use with analgesics may be obtained by the administration of 12.5 to 25 mg in children and 25 to 50 mg doses in adults.

Promethazine HCl Oral Solution is contraindicated for children under 2 years of age.

⛔ Contraindications 66 words ▾

CONTRAINDICATIONS Promethazine Hydrochloride Syrup (Promethazine Hydrochloride Oral Solution, USP) is contraindicated for use in pediatric patients less than two years of age. Promethazine HCl Oral Solution is contraindicated in comatose states, and in individuals known to be hypersensitive or to have had an idiosyncratic reaction to promethazine or to other phenothiazines. Antihistamines are contraindicated for use in the treatment of lower respiratory tract symptoms, including asthma.

⚠️ Warnings ~3 min read ▾

WARNINGS Promethazine Hydrochloride Oral Solution should not be used in pediatric patients less than 2 years of age because of the potential for fatal respiratory depression. Postmarketing cases of respiratory depression, including fatalities, have been reported with use of promethazine in pediatric patients less than 2 years of age. A wide range of weight-based doses of promethazine have resulted in respiratory depression in these patients.

Caution should be exercised when administering promethazine to pediatric patients 2 years of age and older. It is recommended that the lowest effective dose of promethazine be used in pediatric patients 2 years of age and older and concomitant administration of other drugs with respiratory depressant effects be avoided. CNS Depression Promethazine HCl Oral Solution may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a vehicle or operating machinery.

The impairment may be amplified by concomitant use of other central-nervous-system depressants such as alcohol, sedatives/hypnotics (including barbiturates), narcotics, narcotic analgesics, general anesthetics, tricyclic antidepressants, and tranquilizers; therefore, such agents should either be eliminated or given in reduced dosage in the presence of promethazine HCl (see PRECAUTIONS – Information for Patients and Drug Interactions ). Respiratory Depression Promethazine HCl Oral Solution may lead to potentially fatal respiratory depression.

Use of Promethazine HCl Oral Solution in patients with compromised respiratory function (e.g., COPD, sleep apnea) should be avoided. Lower Seizure Threshold Promethazine HCl Oral Solution may lower seizure threshold. It should be used with caution in persons with seizure disorders or in persons who are using concomitant medications, such as narcotics or local anesthetics, which may also affect seizure threshold.

Bone-Marrow Depression Promethazine HCl Oral Solution should be used with caution in patients with bone-marrow depression. Leukopenia and agranulocytosis have been reported, usually when Promethazine HCl Oral Solution has been used in association with other known marrow-toxic agents. Neuroleptic Malignant Syndrome A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with promethazine HCl alone or in combination with antipsychotic drugs.

Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac dysrhythmias). The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS).

Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever and primary central nervous system (CNS) pathology. The management of NMS should include 1) immediate discontinuation of promethazine HCl, antipsychotic drugs, if any, and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for uncomplicated NMS.

Since recurrences of NMS have been reported with phenothiazines, the reintroduction of promethazine HCl should be carefully considered. Use in Pediatric Patients Promethazine HCl Oral Solution is contraindicated for use in pediatric patients less than two years of age. Caution should be exercised when administering Promethazine HCl Oral Solution to pediatric patients 2 years of age a… [Excerpted — this section continues on DailyMed.]

🤒 Adverse Reactions 169 words ▾

ADVERSE REACTIONS Central Nervous System – Drowsiness is the most prominent CNS effect of this drug. Sedation, somnolence, blurred vision, dizziness, confusion, disorientation, and extrapyramidal symptoms such as oculogyric crisis, torticollis, and tongue protrusion; lassitude, tinnitus, incoordination, fatigue, euphoria, nervousness, diplopia, insomnia, tremors, convulsive seizures, excitation, catatonic-like states, hysteria. Hallucinations have also been reported.

Cardiovascular – Increased or decreased blood pressure, tachycardia, bradycardia, faintness. Dermatologic– Dermatitis, photosensitivity, urticaria. Hematologic – Leukopenia, thrombocytopenia, thrombocytopenic purpura, agranulocytosis.

Gastrointestinal– Dry mouth, nausea, vomiting, jaundice. Respiratory– Asthma, nasal stuffiness, respiratory depression (potentially fatal) and apnea (potentially fatal) (see WARNINGS-Respiratory Depression ). Other– Angioneurotic edema.

Neuroleptic malignant syndrome (potentially fatal) has also been reported (see WARNINGS-Neuroleptic Malignant Syndrome ). Paradoxical Reactions Hyperexcitability and abnormal movements have been reported in patients following a single administration of promethazine HCl. Consideration should be given to the discontinuation of promethazine HCl and to the use of other drugs if these reactions occur.

Respiratory depression, nightmares, delirium, and agitated behavior have also been reported in some of these patients.

🔄 Drug Interactions 198 words ▾

Drug Interactions CNS Depressants – Promethazine HCl Oral Solution may increase, prolong, or intensify the sedative action of other central-nervous-system depressants such as alcohol, sedatives/hypnotics (including barbiturates), narcotics, narcotic analgesics, general anesthetics, tricyclic antidepressants, and tranquilizers; therefore, such agents should be avoided or administered in reduced dosage to patients receiving promethazine HCl. When given concomitantly with Promethazine HCl Oral Solution, the dose of barbiturates should be reduced by at least one-half, and the dose of narcotics should be reduced by one-quarter to one-half.

Dosage must be individualized. Excessive amounts of promethazine HCl relative to a narcotic may lead to restlessness and motor hyperactivity in the patient with pain; these symptoms usually disappear with adequate control of the pain. Epinephrine – Because of the potential for Promethazine HCl Oral Solution to reverse epinephrine’s vasopressor effect, epinephrine should NOT be used to treat hypotension associated with Promethazine HCl Oral Solution overdose.

Anticholinergics– Concomitant use of other agents with anticholinergic properties should be undertaken with caution. Monoamine Oxidase Inhibitors (MAOI) – Drug interactions, including an increased incidence of extrapyramidal effects, have been reported when some MAOI and phenothiazines are used concomitantly. This possibility should be considered with Promethazine HCl Oral Solution.

🔄 Drug / Laboratory Test Interactions 55 words ▾

Drug/Laboratory Test Interactions The following laboratory tests may be affected in patients who are receiving therapy with promethazine HCl: Pregnancy Tests Diagnostic pregnancy tests based on immunological reactions between HCG and anti-HCG may result in false-negative or false-positive interpretations. Glucose Tolerance Test An increase in blood glucose has been reported in patients receiving promethazine HCl.

🤰 Pregnancy ~1 min read ▾

Pregnancy Teratogenic Effects-Pregnancy Category C Teratogenic effects have not been demonstrated in rat-feeding studies at doses of 6.25 and 12.5 mg/kg of promethazine HCl. These doses are from approximately 2.1 to 4.2 times the maximum recommended total daily dose of promethazine for a 50-kg subject, depending upon the indication for which the drug is prescribed. Daily doses of 25 mg/kg intraperitoneally have been found to produce fetal mortality in rats.

Specific studies to test the action of the drug on parturition, lactation, and development of the animal neonate were not done, but a general preliminary study in rats indicated no effect on these parameters. Although antihistamines have been found to produce fetal mortality in rodents, the pharmacological effects of histamine in the rodent do not parallel those in man. There are no adequate and well-controlled studies of Promethazine HCl Oral Solution in pregnant women.

Promethazine HCl Oral Solution should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects Promethazine HCl Oral Solution administered to a pregnant woman within two weeks of delivery may inhibit platelet aggregation in the newborn. Labor and Delivery Promethazine HCl Oral Solution may be used alone or as an adjunct to narcotic analgesics during labor (see DOSAGE AND ADMINISTRATION ).

Limited data suggest that use of Promethazine HCl Oral Solution during labor and delivery does not have an appreciable effect on the duration of labor or delivery and does not increase the risk of need for intervention in the newborn. The effect on later growth and development of the newborn is unknown (see also Nonteratogenic Effects ).

🧒 Pediatric Use 54 words ▾

Pediatric Use Promethazine HCl Oral Solution is contraindicated for use in pediatric patients less than two years of age (see WARNINGS – Boxed Warning and Use in Pediatric Patients ). Promethazine HCl Oral Solution should be used with caution in pediatric patients 2 years of age and older (see WARNINGS-Use in Pediatric Patients ).

🆘 Overdosage ~1 min read ▾

OVERDOSAGE Signs and symptoms of overdosage with promethazine HCl range from mild depression of the central nervous system and cardiovascular system to profound hypotension, respiratory depression, unconsciousness, and sudden death. Other reported reactions include hyperreflexia, hypertonia, ataxia, athetosis, and extensor-plantar reflexes (Babinski reflex). Stimulation may be evident, especially in children and geriatric patients.

Convulsions may rarely occur. A paradoxical-type reaction has been reported in children receiving single doses of 75 mg to 125 mg orally, characterized by hyperexcitability and nightmares. Atropine-like signs and symptoms – dry mouth, fixed, dilated pupils, flushing, as well as gastrointestinal symptoms - may occur.

Treatment Treatment of overdosage is essentially symptomatic and supportive. Only in cases of extreme overdosage or individual sensitivity do vital signs, including respiration, pulse, blood pressure, temperature, and EKG, need to be monitored. Activated charcoal orally or by lavage may be given, or sodium or magnesium sulfate orally as a cathartic.

Attention should be given to the reestablishment of adequate respiratory exchange through provision of a patient airway and institution of assisted or controlled ventilation. Diazepam may be used to control convulsions. Acidosis and electrolyte losses should be corrected.

Note that any depressant effects of promethazine HCl are not reversed by naloxone. Avoid analeptics which may cause convulsions. The treatment of choice for resulting hypotension is administration of intravenous fluids, accompanied by repositioning if indicated.

In the event that vasopressors are considered for the management of severe hypotension which does not respond to intravenous fluids and repositioning, the administration of norepinephrine or phenylephrine should be considered. EPINEPHRINE SHOULD NOT BE USED, since its use in patients with partial adrenergic blockade may further lower the blood pressure. Extrapyramidal reactions may be treated with anticholinergic antiparkinson agents, diphenhydramine, or barbiturates.

Oxygen may also be administered. Limited experience with dialysis indicates that it is not helpful.

🧬 Clinical Pharmacology 127 words ▾

CLINICAL PHARMACOLOGY Promethazine is a phenothiazine derivative which differs structurally from the antipsychotic phenothiazines by the presence of a branched side chain and no ring substitution. It is thought that this configuration is responsible for its relative lack (1/10 that of chlorpromazine) of dopamine antagonist properties. Promethazine is an H 1 receptor blocking agent.

In addition to its antihistaminic action, it provides clinically useful sedative and antiemetic effects. Promethazine is well absorbed from the gastrointestinal tract. Clinical effects are apparent within 20 minutes after oral administration and generally last four to six hours, although they may persist as long as 12 hours.

Promethazine is metabolized by the liver to a variety of compounds; the sulfoxides of promethazine and N-demethylpromethazine are the predominant metabolites appearing in the urine.

⚠️ Precautions ~2 min read ▾

PRECAUTIONS General Drugs having anticholinergic properties should be used with caution in patients with narrow-angle glaucoma, prostatic hypertrophy, stenosing peptic ulcer, pyloroduodenal obstruction, and bladder-neck obstruction. Promethazine HCl Oral Solution should be used cautiously in persons with cardiovascular disease or with impairment of liver function. Information for Patients Patients should be advised to measure Promethazine HCl Oral Solution with an accurate measuring device.

A household teaspoon is not an accurate measuring device and could lead to overdosage, especially when a half a teaspoon is measured. A pharmacist can recommend an appropriate measuring device and can provide instructions for measuring the correct dose. Promethazine HCl Oral Solution may cause marked drowsiness or impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a vehicle or operating machinery.

Ambulatory patients should be told to avoid engaging in such activities until it is known that they do not become drowsy or dizzy from promethazine therapy. Pediatric patients should be supervised to avoid potential harm in bike riding or in other hazardous activities. The concomitant use of alcohol or other central-nervous-system depressants, such as sedatives/hypnotics (including barbiturates), narcotics, narcotic analgesics, general anesthetics, tricyclic antidepressants, and tranquilizers may enhance impairment (see WARNINGS-CNS Depression and PRECAUTIONS–Drug Interactions ).

Patients should be advised to report any involuntary muscle movements. Avoid prolonged exposure to the sun. Drug Interactions CNS Depressants – Promethazine HCl Oral Solution may increase, prolong, or intensify the sedative action of other central-nervous-system depressants such as alcohol, sedatives/hypnotics (including barbiturates), narcotics, narcotic analgesics, general anesthetics, tricyclic antidepressants, and tranquilizers; therefore, such agents should be avoided or administered in reduced dosage to patients receiving promethazine HCl.

When given concomitantly with Promethazine HCl Oral Solution, the dose of barbiturates should be reduced by at least one-half, and the dose of narcotics should be reduced by one-quarter to one-half. Dosage must be individualized. Excessive amounts of promethazine HCl relative to a narcotic may lead to restlessness and motor hyperactivity in the patient with pain; these symptoms usually disappear with adequate control of the pain.

Epinephrine – Because of the potential for Promethazine HCl Oral Solution to reverse epinephrine’s vasopressor effect, epinephrine should NOT be used to treat hypotension associated with Promethazine HCl Oral Solution overdose. Anticholinergics– Concomitant use of other agents with anticholinergic properties should be undertaken with caution. Monoamine Oxidase Inhibitors (MAOI) – Drug interactions, including an increased incidence of extrapyramidal effects, have been reported when some MAOI and phenothiazines are used concomitantly.

This possibility should be considered with Promethazine HCl Oral Solution. Drug/Laboratory Test Interactions The following laboratory tests may be affected in patients who are receiving therapy with promethazine HCl: Pregnancy Tests Diagnostic pregnancy tests based on immunological reactions between HCG and anti-HCG may result in false-negative or false-positive interpretations. Glucose Tolerance Test An increase in blood glucose has been reported in patients receiving promethazine HCl.

Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term animal studies have not been performed to assess the carcinogenic potential of promethazine, nor are there other animal or human data concerning carcinogenicity, mutagenicity, or impairment of fertility with this drug. Promethazine was nonmutagenic in the Salmonella test system of Ames. Pregnancy Teratogenic Effects-Pregnancy Category C Teratogenic effects have no… [Excerpted — this section continues on DailyMed.]

🍼 Nursing Mothers 64 words ▾

Nursing Mothers It is not known whether promethazine HCl is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Promethazine HCl Oral Solution, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by ATLANTIC BIOLOGICALS CORP. Listing status can change — the directory data on this page refreshes weekly.
