Uses

Famotidine is known as an H2 histamine blocker. It works by reducing the amount of acid in your stomach. It is used to prevent and treat heartburn and other symptoms caused by too much acid in the stomach (acid indigestion).

How to use Pepcid AC

Follow all directions on the product package. If you are uncertain about any of the information, consult your doctor or pharmacist.

Take this drug as needed to stop/prevent heartburn and indigestion, or as directed by your doctor. Chew 1 tablet completely and swallow. Do not swallow whole. You may take famotidine with or without food. Do not take more than 2 tablets in 24 hours unless directed by your doctor.

To prevent heartburn and acid indigestion, take famotidine 10 to 60 minutes before eating food or drinking beverages that can cause indigestion.

Side Effects

Headache, dizziness, constipation, or diarrhea may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

If your doctor has directed you to use this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these rare but very serious side effects occur: easy bruising/bleeding, fast/slow/irregular heartbeat, signs of infection (such as fever, persistent sore throat, cough), mental/mood changes (such as restlessness, confusion, depression, hallucinations), seizure.

A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Precautions

Before taking famotidine, tell your doctor or pharmacist if you are allergic to it; or to other acid blockers (such as cimetidine, ranitidine); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

If you have the following health problem, consult your doctor or pharmacist before using this medication: kidney problems.

Some symptoms may actually be signs of a more serious condition. Get medical help right away if you have: heartburn with lightheadedness/sweating/dizziness, chest/jaw/arm/shoulder pain (especially with shortness of breath, unusual sweating), unexplained weight loss.

In addition, before you self-treat with this medication, get medical help right away if you have any of these signs of a serious condition: trouble/pain swallowing food, bloody vomit, vomit that looks like coffee grounds, bloody/black stools, heartburn for over 3 months, frequent chest pain, frequent wheezing (especially with heartburn), nausea/vomiting, stomach pain.

Older adults may be more sensitive to the side effects of this drug, especially confusion.

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 (such as ibuprofen, naproxen) that can cause stomach irritation/ulcers. However, if your doctor has directed you to take low-dose aspirin for heart attack or stroke prevention (usually at dosages of 81-325 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your pharmacist about using those products safely.

This medication and similar acid blockers (such as cimetidine, ranitidine) are available both over-the-counter and by prescription. Do not take them at the same time.

Overdose

If overdose is suspected, contact a poison control center or emergency room immediately. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center.

Notes

Lifestyle changes such as stress reduction programs, stopping smoking, limiting alcohol, and diet changes (such as avoiding caffeine, certain spices) may help this medication work better. Talk to your doctor or pharmacist about lifestyle changes that might benefit you.

Missed Dose

Not applicable.
