famotidine (PF) IV Uses
Famotidine is used to treat ulcers of the stomach or intestines. It may be used to prevent intestinal ulcers from returning after treatment. This medication is also used to treat certain stomach and throat problems caused by too much acid (e.g., Zollinger-Ellison syndrome, erosive esophagitis) or a backward flow of stomach acid into the esophagus (gastroesophageal reflux disease-GERD).
This form of famotidine is given by vein and is used to treat these conditions for a short time when you cannot take the medication by mouth. Your doctor should switch you to taking this medication by mouth when possible.
This medication is injected into a vein as directed by your doctor. The dosage and length of treatment are based on your medical condition and response to treatment. In children, dosage may also be based on body weight.
If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before injecting each dose, clean the injection site with rubbing alcohol. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.
Tell your doctor if your condition persists or worsens.

famotidine (PF) IV Interactions
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Since famotidine reduces the amount of acid in your stomach, it may also change the absorption of certain medications and affect how they work. Some examples of affected drugs include atazanavir, dasatinib, delavirdine, certain azole antifungals (such as itraconazole, ketoconazole), among others. Ask your doctor or pharmacist if any of the medications you take are affected by famotidine and how to manage this interaction.
Check the labels on all your medicines because they may contain aspirin or aspirin-like NSAIDs (e.g., ibuprofen, naproxen) that can cause stomach irritation/ulcers. Ask your doctor or pharmacist about the safe use of these products. Low-dose aspirin, as prescribed by your doctor for specific medical reasons such as heart attack or stroke prevention (usually at dosages of 81-325 milligrams per day), should be continued. Consult your doctor for more details.
