Generic name: famotidine
Dosage form: Injection
The information at Drugs.com is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.
In some hospitalized patients with pathological hypersecretory conditions or intractable ulcers, or in patients who are unable to take oral medication, PEPCID Injection Premixed or PEPCID Injection may be administered until oral therapy can be instituted.
The recommended dosage for PEPCID Injection Premixed and PEPCID Injection in adult patients is 20 mg intravenously q 12 h.
The doses and regimen for parenteral administration in patients with GERD have not been established.
Dosage for Pediatric Patients<1 year of age Gastroesophageal Reflux Disease (GERD)
The studies described in PRECAUTIONS, Pediatric Patients <1 year of age suggest the following starting doses in pediatric patients<1 year of age: Gastroesophageal Reflux Disease (GERD) - 0.5 mg/kg/dose of famotidine oral suspension for the treatment of GERD for up to 8 weeks once daily in patients <3 months of age and 0.5 mg/kg/dose twice daily in patients 3 months to <1 year of age. Patients should also be receiving conservative measures (e.g., thickened feedings). The use of intravenous famotidine in pediatric patients <1 year of age with GERD has not been adequately studied.
Dosage for Pediatric Patients 1-16 years of age
The studies described in PRECAUTIONS, Pediatric Patients 1-16 years of age suggest that the starting dose in pediatric patients 1-16 years of age is 0.25 mg/kg intravenously (injected over a period of not less than two minutes or as a 15-minute infusion) q 12 h up to 40 mg/day.
While published uncontrolled clinical studies suggest effectiveness of famotidine in the treatment of peptic ulcer, data in pediatric patients are insufficient to establish percent response with dose and duration of therapy. Therefore, treatment duration (initially based on adult duration recommendations) and dose should be individualized based on clinical response and/or gastric pH determination and endoscopy. Published uncontrolled studies in pediatric patients 1-16 years of age have demonstrated gastric acid suppression with doses up to 0.5 mg/kg intravenously q 12 h.
Dosage Adjustments for Patients with Moderate or Severe Renal Insufficiency
In adult patients with moderate (creatinine clearance<50 mL/min) or severe (creatinine clearance <10 mL/min) renal insufficiency, the elimination half-life of PEPCID is increased. For patients with severe renal insufficiency, it may exceed 20 hours, reaching approximately 24 hours in anuric patients. Since CNS adverse effects have been reported in patients with moderate and severe renal insufficiency, to avoid excess accumulation of the drug in patients with moderate or severe renal insufficiency, the dose of PEPCID Injection Premixed or PEPCID Injection may be reduced to half the dose, or the dosing interval may be prolonged to 36-48 hours as indicated by the patient's clinical response.
Based on the comparison of pharmacokinetic parameters for PEPCID in adults and pediatric patients, dosage adjustment in pediatric patients with moderate or severe renal insufficiency should be considered.
Pathological Hypersecretory Conditions (e.g., Zollinger-Ellison Syndrome, Multiple Endocrine Adenomas)
The dosage of PEPCID in patients with pathological hypersecretory conditions varies with the individual patient. The recommended adult intravenous dose is 20 mg q 12 h. Doses should be adjusted to individual patient needs and should continue as long as clinically indicated. In some patients, a higher starting dose may be required. Oral doses up to 160 mg q 6 h have been administered to some adult patients with severe Zollinger-Ellison Syndrome.
PEPCID Injection Premixed
PEPCID Injection Premixed, supplied in Galaxy1 containers (PL 2501 Plastic), is a 50 mL iso-osmotic solution premixed with 0.9% sodium chloride for administration as an infusion over a 15-30 minute period. This premixed solution is for intravenous use only using sterile equipment.

Directions for Use of Galaxy® Containers
Check the container for minute leaks prior to use by squeezing the bag firmly. If leaks are found, discard solution as sterility may be impaired. Do not add supplementary medication. Do not use unless solution is clear and seal is intact.
CAUTION: Do not use plastic containers in series connections. Such use could result in air embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is complete.
Preparation for administration:
- Suspend container from eyelet support.
- Remove plastic protector from outlet port at bottom of container.
- Attach administration set. Refer to complete directions accompanying set.
To prepare PEPCID intravenous solutions, aseptically dilute 2 mL of PEPCID Injection (solution containing 10 mg/mL) with 0.9% Sodium Chloride Injection or other compatible intravenous solution (see Stability, PEPCID Injection) to a total volume of either 5 mL or 10 mL and inject over a period of not less than 2 minutes.
To prepare PEPCID intravenous infusion solutions, aseptically dilute 2 mL of PEPCID Injection with 100 mL of 5% dextrose or other compatible solution (see Stability, PEPCID Injection), and infuse over a 15-30 minute period.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.
PEPCID Injection Premixed
PEPCID Injection Premixed, as supplied premixed in 0.9% sodium chloride in Galaxy® containers (PL 2501 Plastic), is stable through the labeled expiration date when stored under the recommended conditions. (See HOW SUPPLIED, Storage.)
When added to or diluted with most commonly used intravenous solutions, e.g., Water for Injection, 0.9% Sodium Chloride Injection, 5% and 10% Dextrose Injection, or Lactated Ringer's Injection, diluted PEPCID Injection is physically and chemically stable (i.e., maintains at least 90% of initial potency) for 7 days at room temperature — see HOW SUPPLIED, Storage.
When added to or diluted with Sodium Bicarbonate Injection, 5%, PEPCID Injection at a concentration of 0.2 mg/mL (the recommended concentration of PEPCID intravenous infusion solutions) is physically and chemically stable (i.e., maintains at least 90% of initial potency) for 7 days at room temperature — see HOW SUPPLIED, Storage. However, a precipitate may form at higher concentrations of PEPCID Injection (>0.2 mg/mL) in Sodium Bicarbonate Injection, 5%.
