Clinical
Famotidine injection is used in people who are hospitalized to treat certain conditions in which the stomach produces too much acid or to treat ulcers (sores in the lining of the stomach or intestine) that were not successfully treated with other medications. Famotidine injection is also used on a short-term basis in people who cannot take oral medication to treat ulcers, to prevent ulcers from returning after they have healed, to treat gastroesophageal reflux disease (GERD, a condition in which backward flow of acid from the stomach causes heartburn and injury of the esophagus [tube betwe...

- Why am I getting famotidine through an IV?
- For adults it is generally given about every 12 hours through a vein. Your care team will set the exact dose and timing, which may be adjusted if your kidneys aren't working well.
- The common ones are headache, dizziness, constipation, and diarrhea. You may also notice brief irritation where the IV goes in. Tell your nurse about any of these.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Central Nervous System (CNS) Adverse Reactions : Reported in elderly patients and patients with moderate and severe renal impairment; monitor elderly patients for CNS adverse reactions. ( 5.1 , 8.5 , 8.6 ) Concurrent GI Malignancy : Absence of GI symptoms does not preclude the presence of gastric malignancy; evaluate prior to initiating therapy. ( 5.2 ) Risk of Benzyl Alcohol Toxicity in Neonates : Famotidine Injection is not approved in neonates.
Serious and fatal adverse reactions have been reported in low-birth weight and preterm neonates who received benzyl-alcohol-containing drugs intravenously. The minimum amount of benzyl alcohol at which these serious adverse reactions may occur is not known. ( 5.3 )
5.1Central Nervous System Adverse Reactions Central nervous system (CNS) adverse reactions, including confusion, delirium, hallucinations, disorientation, agitation, seizures, and lethargy, have been reported in elderly patients and patients with moderate and severe renal impairment treated with famotidine. Monitor elderly patients for CNS adverse reactions [see Use in Specific Populations ( 8.5 )] . Dosage adjustments are recommended in adult patients with moderate and severe renal impairment due to higher famotidine systemic exposure compared to patients with normal renal function [see Dosage and Administration ( 2.3 ), Use in Specific Populations ( 8.6 ), and Clinical Pharmacology ( 12.3 )].
5.2Concurrent Gastric Malignancy In adults, symptomatic response to therapy with Famotidine Injection does not preclude the presence of gastric malignancy. Consider evaluation for gastric malignancy in adult patients who have a suboptimal response or an early symptomatic relapse after completing treatment with Famotidine Injection.
5.3Risk of Benzyl Alcohol Toxicity in Neonates Famotidine Injection is not approved in neonates. Serious adverse reactions, including fatal reactions, of new onset or worsening metabolic acidosis that progressed to neurotoxicity, and in some cases gasping syndrome, have been reported in low-birth weight neonates (less than 2,500 grams) and preterm neonates (gestational age less than 34 weeks) who received benzyl alcohol (BA)-containing drugs intravenously. Gasping syndrome is a life-threatening condition in neonates caused by BA toxicity and is primarily characterized by multiorgan dysfunction secondary to metabolic acidosis, which leads to gasping respirations and death.
The minimum amount of BA at which these serious adverse reactions, including fatal reactions, may occur is not known (Famotidine Injection contains 3.6 mg of BA per mL) [see Use in Specific Populations ( 8.4 )] .
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Most common adverse reactions (>1%) are: headache, dizziness, constipation, and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Sagent Pharmaceuticals at 1-866-625-1618 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of Famotidine Injection has been established based on adequate and well-controlled studies of an oral famotidine product. The following is a summary of the adverse reactions reported in those studies.
Oral famotidine was studied in 7 U.S. and international placebo- and active-controlled trials in approximately 2,500 patients. A total of 1,442 patients were treated with oral famotidine, including 302 treated with 40 mg twice daily, 456 treated with 20 mg twice daily, 461 treated with 40 mg once daily, and 396 treated with 20 mg once daily. The population was 17 to 91 years old, fairly well distributed between sex and race; however, the predominant race was White.
Adverse reactions reported in ≥1% of patients treated with oral famotidine in clinical trials were: headache, dizziness, constipation, and diarrhea. The following other adverse reactions were reported in less than 1% of patients treated with oral famotidine in clinical trials: Body as a Whole : fever, asthenia, fatigue Cardiovascular : palpitations Gastrointestinal : cholestatic jaundice, elevated liver enzymes, vomiting, nausea, abdominal discomfort, anorexia, dry mouth Hematologic : thrombocytopenia Hypersensitivity : orbital edema, rash, conjunctival injection, bronchospasm Musculoskeletal : musculoskeletal pain, arthralgia Nervous System/Psychiatric : seizure, hallucinations, depression, anxiety, decreased libido, insomnia, somnolence Respiratory : interstitial pneumonia Skin : pruritus, dry skin, flushing Special Senses : tinnitus, taste disorder Other : impotence Adverse reactions reported with oral famotidine may also occur with Famotidine Injection.
In addition, transient irritation at the injection site was reported with intravenous famotidine.
6.2Postmarketing Experience The following adverse reactions have been identified during post-approval use of famotidine. Because these reactions are 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. Cardiovascular : arrhythmia, AV block, prolonged QT interval Gastrointestinal : cholestatic jaundice, hepatitis Hematologic : agranulocytosis, pancytopenia, leukopenia Hypersensitivity : anaphylaxis, angioedema, facial edema, urticaria Musculoskeletal : rhabdomyolysis, muscle cramps Nervous System/Psychiatric : confusion, agitation, paresthesia Respiratory : interstitial pneumonia Skin : toxic epidermal necrolysis/Stevens-Johnson syndrome
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Drugs Dependent on Gastric pH for Absorption : Systemic exposure of the concomitant drug may be significantly reduced leading to loss of efficacy. See the prescribing information for other drugs dependent on gastric pH for absorption. ( 7.1 ) Tizanidine (CYP1A2) Substrate : Potential for substantial increases in blood concentrations of tizanidine resulting in hypotension, bradycardia or excessive drowsiness; avoid concomitant use, if possible.
( 7.2 )
7.1Drugs Dependent on Gastric pH for Absorption Famotidine can reduce the absorption of other drugs due to its effect on reducing intragastric acidity, leading to loss of efficacy of the concomitant drug. See the prescribing information for other drugs dependent on gastric pH for absorption.
7.2Tizanidine (CYP1A2 Substrate) Although not studied clinically, famotidine is considered a weak CYP1A2 inhibitor and may lead to substantial increases in blood concentrations of tizanidine, a CYP1A2 substrate. Avoid concomitant use with Famotidine Injection. If concomitant use is necessary, monitor for hypotension, bradycardia or excessive drowsiness. Refer to the full prescribing information for tizanidine.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Renal Impairment : QT prolongation reported in patients with moderate and severe renal impairment. ( 2.3 , 8.6 )
8.1Pregnancy Risk Summary Available data with H 2 -receptor antagonists, including famotidine, in pregnant women over decades of use have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Reproductive studies have been performed in rats and rabbits at intravenous doses of up to 200 mg/kg/day, with no obvious adverse developmental effects (see Data ) . Famotidine Injection contains benzyl alcohol as a preservative [see How Supplied/Storage and Handling ( 16 )] .
Because benzyl alcohol is rapidly metabolized by a pregnant female, benzyl alcohol exposure in the fetus is unlikely. The background risk for 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 background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Reproductive studies have been performed in rats and rabbits at oral doses of up to 2,000 and 500 mg/kg/day, respectively, and in both species at intravenous doses of up to 200 mg/kg/day and have revealed no significant evidence of impaired fertility or harm to the fetus due to famotidine.
8.2Lactation Risk Summary There are limited data available on the presence of famotidine in human breast milk following oral administration. There were no effects on the breastfed infant. There are no data on famotidine effects on milk production.
Famotidine Injection contains benzyl alcohol as a preservative. Because benzyl alcohol is rapidly metabolized by a lactating female, benzyl alcohol exposure in the breastfed neonate is unlikely. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Famotidine Injection and any potential adverse effects on the breastfed child from famotidine or from the underlying maternal condition.
8.4Pediatric Use Peptic Ulcer Disease The safety and effectiveness of Famotidine Injection have been established in pediatric patients 1 year to less than 17 years of age for the treatment of peptic ulcer disease in hospitalized patients or as an alternative to oral famotidine. Use of Famotidine Injection in this age group is supported by evidence from adequate and well-controlled studies of oral famotidine in adults with additional pharmacokinetic and pharmacodynamic data in pediatric patients 1 year to less than 17 years of age [see Dosage and Administration ( 2.2 ) and Clinical Pharmacology ( 12.2 , 12.3 )] .
A safe and effective dosage has not been established in pediatric patients 1 year to less than 17 years of age with renal impairment for the treatment of peptic ulcer disease. The safety and effectiveness of Famotidine Injection for the treatment of peptic ulcer disease in pediatric patients less than 1 year of age have not been established. Other Conditions The safety and effectiveness of Famotidine Injection for the treatment of symptomatic nonerosive GERD, erosive esophagitis due to GERD, pathological hypersecretory conditions and reduction of the risk of DU recurrence have not been established in pediatric patients.
Risk of Benzyl Alcohol Toxicity in Neonates Famotidine Injection is not approved for use in neonates. Serious adverse reactions, including fatal reactions, of new onset or worsening metabolic acidosis that progressed to neurotoxicity, and in some cases gasping syndrome, have been reported in low-birth weight neonates and preterm neonates who received benzyl alcohol (BA)-containing drugs intravenously.

🧒 Pediatric Use ▾
8.4Pediatric Use Peptic Ulcer Disease The safety and effectiveness of Famotidine Injection have been established in pediatric patients 1 year to less than 17 years of age for the treatment of peptic ulcer disease in hospitalized patients or as an alternative to oral famotidine. Use of Famotidine Injection in this age group is supported by evidence from adequate and well-controlled studies of oral famotidine in adults with additional pharmacokinetic and pharmacodynamic data in pediatric patients 1 year to less than 17 years of age [see Dosage and Administration ( 2.2 ) and Clinical Pharmacology ( 12.2 , 12.3 )] .
A safe and effective dosage has not been established in pediatric patients 1 year to less than 17 years of age with renal impairment for the treatment of peptic ulcer disease. The safety and effectiveness of Famotidine Injection for the treatment of peptic ulcer disease in pediatric patients less than 1 year of age have not been established. Other Conditions The safety and effectiveness of Famotidine Injection for the treatment of symptomatic nonerosive GERD, erosive esophagitis due to GERD, pathological hypersecretory conditions and reduction of the risk of DU recurrence have not been established in pediatric patients.
Risk of Benzyl Alcohol Toxicity in Neonates Famotidine Injection is not approved for use in neonates. Serious adverse reactions, including fatal reactions, of new onset or worsening metabolic acidosis that progressed to neurotoxicity, and in some cases gasping syndrome, have been reported in low-birth weight neonates and preterm neonates who received benzyl alcohol (BA)-containing drugs intravenously. Gasping syndrome is a life-threatening condition in neonates caused by BA toxicity that is characterized by new onset or worsening metabolic acidosis with gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and kidney failure, hypotension, bradycardia, and gasping respirations followed by death.
In reported cases, BA in amounts of 99 to 234 mg/kg/day produced blood BA levels of 6.6 to 14.9 mg/dL, but the minimum amount of BA at which gasping syndrome may occur in neonates is not known (Famotidine Injection contains 3.6 mg of BA per mL) [see Warnings and Precautions ( 5.3 )] .
🧓 Geriatric Use ▾
8.5Geriatric Use Of the 1,442 patients treated with oral famotidine in clinical studies, approximately 10% were 65 and older. In these studies, no overall differences in safety or effectiveness were observed between elderly and younger patients. In elderly patients, there are no clinically significant age-related changes in the pharmacokinetics of famotidine [see Clinical Pharmacology ( 12.3 )] .
In postmarketing experience, CNS adverse reactions have been reported in elderly patients with and without renal impairment receiving famotidine. Monitor elderly patients for CNS adverse reactions [see Warnings and Precautions ( 5.1 )] . Famotidine is known to be substantially excreted by the kidney, and the risk of adverse reactions to Famotidine Injection may be greater in elderly patients, particularly those with impaired renal function [see Dosage and Administration ( 2.3 ) and Use in Specific Populations ( 8.6 )].
🆘 Overdosage ▾
10 OVERDOSAGE Adverse reactions reported in cases of overdosage are similar to the adverse reactions reported with use of the recommended dosage [see Adverse Reactions ( 6 )]. In the event of overdosage, treatment should be symptomatic and supportive. In the event of overdosage, monitor the patient, and employ supportive therapy.
Due to low binding to plasma proteins, famotidine is eliminated by hemodialysis. There is limited experience on the usefulness of hemodialysis as a treatment for famotidine overdosage. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Famotidine is a competitive inhibitor of histamine H 2 -receptors. The primary clinically important pharmacologic activity of famotidine is inhibition of gastric secretion. Both the acid concentration and volume of gastric secretion are suppressed by famotidine, while changes in pepsin secretion are proportional to volume output.
12.2Pharmacodynamics Adults Famotidine inhibited basal and nocturnal gastric secretion, as well as secretion stimulated by food and pentagastrin. After intravenous administration, the maximum effect was achieved within 30 minutes. Single intravenous doses of 20 mg inhibited nocturnal secretion for a period of 10 to 12 hours.
Famotidine had little or no effect on fasting or postprandial serum gastrin levels. Gastric emptying and exocrine pancreatic function were not affected by famotidine. In clinical pharmacology studies, systemic effects of famotidine in the central nervous system (CNS), cardiovascular, respiratory or endocrine systems were not noted.
Also, no antiandrogenic effects were noted. Serum hormone levels, including prolactin, cortisol, thyroxine (T 4 ), and testosterone, were not altered after treatment with famotidine. Pediatric Patients Pharmacodynamics of famotidine were evaluated in five pediatric patients 2 to 13 years of age using the sigmoid E max model.
These data suggest that the relationship between serum concentration of famotidine and gastric acid suppression is similar to that observed in one study of adults ( Table 4 ).

12.3Pharmacokinetics Plasma levels after multiple doses are similar to those after single doses. Distribution Fifteen to 20% of famotidine in plasma is protein bound. Elimination Metabolism Famotidine undergoes minimal first-pass metabolism.
Sixty-five to 70% of an intravenous dose are recovered in the urine as unchanged compound. The only metabolite identified in humans is the S-oxide. Excretion Famotidine has an elimination half-life of 2.5 to 3.5 hours.
Famotidine is eliminated by renal (65 to 70%) and metabolic (30 to 35%) routes. Renal clearance is 250 to 450 mL/minutes, indicating some tubular excretion. Specific Populations Pediatric Patients Table 6 presents pharmacokinetic data for famotidine administered intravenously.
Areas under the curve (AUCs) are normalized to a 0.5 mg/kg intravenous dose for pediatric patients 1 to 15 years of age and compared with an extrapolated 40 mg intravenous dose in adults. Extrapolation is based on results obtained with a 20 mg intravenous adult dose). The pharmacokinetic parameters for pediatric patients, aged 1 year to 15 years, are comparable to those obtained for adults.

🧬 Mechanism of Action ▾
12.1Mechanism of Action Famotidine is a competitive inhibitor of histamine H 2 -receptors. The primary clinically important pharmacologic activity of famotidine is inhibition of gastric secretion. Both the acid concentration and volume of gastric secretion are suppressed by famotidine, while changes in pepsin secretion are proportional to volume output.

0.99Geriatric Patients In elderly patients, there are no clinically significant age-related changes in the pharmacokinetics of famotidine. However, in elderly patients with decreased renal function, the clearance of the drug may be decreased [see Use in Specific Populations ( 8.5 )] . Patients with Renal Impairment In adult patients with severe renal impairment (creatinine clearance less than 30 mL/min), the systemic exposure (AUC) of famotidine increased at least 5-fold.
In adult patients with moderate renal impairment (creatinine clearance between 30 to 60 mL/minute), the AUC of famotidine increased at least 2-fold [see Dosage and Administration ( 2.3 ) and Use in Specific Populations ( 8.6 )]. Drug Interaction Studies Human Organic Anion Transporter (OAT) 1 and 3 In vitro studies indicate that famotidine is a substrate for OAT1 and OAT3. Following coadministration of probenecid (1500 mg), an inhibitor of OAT1 and OAT3, with a single oral 20 mg dose of famotidine in eight healthy subjects, the serum AUC 0-10h of famotidine increased from 424 to 768 ng•hr/mL and the maximum serum concentration (C max ) increased from 73 to 113 ng/mL.
Renal clearance, urinary excretion rate and amount of famotidine excreted unchanged in urine were decreased. The clinical relevance of this interaction is unknown. Multidrug and Toxin Extrusion Protein 1 (MATE-1) An in vitro study showed that famotidine is an inhibitor of MATE-1.
However, no clinically significant interaction with metformin, a substrate for MATE-1, was observed. CYP1A2 Famotidine is a weak CYP1A2 inhibitor [see Drug Interaction ( 7.2 )]
🧬 Pharmacodynamics ▾
12.2Pharmacodynamics Adults Famotidine inhibited basal and nocturnal gastric secretion, as well as secretion stimulated by food and pentagastrin. After intravenous administration, the maximum effect was achieved within 30 minutes. Single intravenous doses of 20 mg inhibited nocturnal secretion for a period of 10 to 12 hours.
Famotidine had little or no effect on fasting or postprandial serum gastrin levels. Gastric emptying and exocrine pancreatic function were not affected by famotidine. In clinical pharmacology studies, systemic effects of famotidine in the central nervous system (CNS), cardiovascular, respiratory or endocrine systems were not noted.
Also, no antiandrogenic effects were noted. Serum hormone levels, including prolactin, cortisol, thyroxine (T 4 ), and testosterone, were not altered after treatment with famotidine. Pediatric Patients Pharmacodynamics of famotidine were evaluated in five pediatric patients 2 to 13 years of age using the sigmoid E max model.
