What is Famotidine?

Famotidine is a non-prescription medication used in dogs and cats to reduce the amount of stomach acid being produced. Although Famotidine is not FDA-approved for use in veterinary medicine, it is a commonly accepted practice for veterinarians to prescribe this medication for dogs and cats.


Dogs and Cats

  • Useful in the treatment and prevention of gastric (stomach) and intestinal ulcers
  • Helps heal ulcers that are already present
How it Works:

Famotidine blocks H-2 receptors from secreting gastric acids into the stomach. Blocking these receptors prevents ulcers from forming and also helps present ulcers time to heal.


Famotidine should be used with caution in pets that are pregnant or pets with heart, kidney, or liver disease.

What should I discuss with my veterinarian before giving famotidine to my pet:

Tell your veterinarian if your pet has heart, liver, or kidney disease. Tell your veterinarian if your pet is pregnant since it may affect weight gain.

How should this medication be given:

Give this medication exactly as directed by your veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Famotidine should not be given with food. Food will decrease its effectiveness. Store famotidine at room temperature away from moisture and light. Keep this medication away from children and pets.

What happens if I miss giving a dose:

Give the missed dose as soon as you remember during the same day. However, if you don't remember until the next day, skip the dose you missed and give only the next regularly scheduled dose. Do not give a double dose of the medication.

What happens if I overdose the pet:

Overdose is rare. If overdose is suspected, seek emergency veterinary medical treatment. Symptoms of famotidine overdose may include vomiting, restlessness, pale gums, rapid heart rate, or collapse.

What should I avoid while giving Famotidine to my pet:

Famotidine should not be used in animals allergic to it. Use famotidine with caution in animals with heart, kidney, or liver disease. Use with caution in pregnant females.

What are the possible side effects of Famotidine:

For dogs and cats, if any of the following serious side effects occur, stop giving famotidine and seek emergency veterinary medical attention; an allergic reaction (difficulty breathing; swelling of the lips; tongue or face; hives). Side effects are rare but may include loss of appetite and tiredness. Other side effects may also occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to the animal.

What other drugs will affect Famotidine:

Tell your veterinarian if your pet is being given antacids, metoclopramide, Sucralfate, digoxin, or ketoconazole as interactions can occur. Give famotidine 2 hours before or 2 hours after the other medications. When given with azathioprine, famotidine may further decrease white blood cell counts.

Talk to your veterinarian or pharmacist before giving any prescription or over the counter medicines including vitamins, and supplements.

Customer Reviews
Famotidine is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Works great My cat has kidney failure and was being given a tiny dose of famotidine by the vet....10 mg spread over 15 days, in cherry help with her vomiting. While it was helping her control her upset stomach, a change in management at the vet coupled with a 400% increase in price, made me want to seek out alternatives. After reading the dosing instructions for this product, I realized that I could provide Sinclair with a much more concentrated dosage myself...simply by investing some time in cutting up the 10 mg tablets into quarters & grinding them. I mix the powder with some water and give it to her with an oral syringe.....she doesn't complain and her stomach has been so much better than it ever was with the vet's meds. Thank you, thank you!

Can awful, awful breath be caused by stomach acid and will Famotidine help?

Asked by: kd
You will need to consult your vet. Bad breath with pets isnt always just Halitosis. It could be teeth issues or other unforseen medical issues. Your vet would need to determine what is the reason for the bad breath and give you the proper medical advice.

Famotidine... How long to take

How long do dogs typically take Famotidine? ESP with history of GI problems.
Asked by: Sammy's dad
My dog takes 5 mg. every 24 hours. She has been on this for 9 months. I think she probably will take it forever. It has improved her appetite and she no longer throws up.

If my dog is 9 pound, is it OK to give her 1 whole pill in the morning and one at night? Or would this be too much medication?

The dose for an adult human in the box calls for 1 pill ( and not to take more than two pills in 24 hrs) to be taken on an empty stomach. Wouldn't this dose be too much medication for a 9 pound dog? Just wonder. Thanks for the advise.
Asked by: Marina
I have a 10 pound toy poodle that has been taking 5mg. every 24 hours for the past several months (on direction of the Vet) She has greatly improved her appetite and no longer throws up. I think this dose is ok for her. I am looking for 10 mg. tabs that are scored so they can be cut in half cleanly. The non scored tablets I find in the drug store do not cut well and the ones I get from the Vet are marked up about 600%

are these pills easily crushed?

Pet will not swallow or chew pills. I need to place them in a pillcrusher, OTC Pepcid has a "coating" on them that makes crushing difficult.
Asked by: Lexiemom
Yes. Get a pill crusher Walgreens/Harmons. I crushed/mixed in syringe with water and put into her mouth.
