Famotidine Side Effects in Cats

Famotidine is a medication that's given to pets that suffer from stomach ulcers and intestinal ulcers. Although this drug is not specifically formulated for use in pets, many owners administer it to their pets because it brings relief from the symptoms of stomach ulcers. You shouldn't administer Famotidine to your cat until you conduct a vet check. Once the vet confirms that the cat is suffering from stomach ulcers, you can discuss the pros and cons of administering this medication, before purchasing it.

How Famotidine Works

There are several H2 receptors that produce gastric acids in the pet's stomach. Famotidine inhibits the activity of the H2 receptors, and this will help the ulcers heal quickly. In addition to this, the cat won't develop new ulcers in the stomach or the intestines.

Dosage and Administration of Famotidine

The medication is available as 10 mg tablets. Cats should be given 0.22 mg of the medication per pound of body weight, once or twice daily. It's best to administer the tablets on an empty stomach at the scheduled time. If you forget to give your pet the medication on time, skip the dose instead of double dosing your pet. Since cats are highly sensitive to medications, you must find out what's the ideal dose for your pet by taking her to the vet.

Famotidine is also used to treat conditions like gastroesophageal reflux disease and esophagitis, but the dosage will change according to the condition your cat is suffering from.

Side Effects of Famotidine Include:

  • Lethargy
  • Lack of appetite
  • Allergic reactions 
  • Drug interactions

What to Watch For

If your cat shows signs of pale gums, difficulty breathing, irregular heartbeat or sudden collapse, you must call for emergency medical care. Similarly, if the pet develops an allergic reaction to the medication and exhibits symptoms like hives, skin reactions or swelling of the lips, you must seek prompt vet help to safeguard your pet's life.

Precautions You Need to Take

Avoid giving Famotidine to your cat if she suffers from heart disorders or liver problems. The medication isn't ideal for cats suffering from kidney problems or pets that are pregnant. Certain drugs when administered along with Famotidine cause side effects. These medications include sucralfate, ketoconazole, azathioprine and antacids. To be on the safe side, inform the vet about any other over the counter medications or supplements you're giving your cat.

Tips for Pet Owners

If your cat suffers from frequent stomach ulcers, you must find out the real cause. The vet will perform several diagnostic tests to rule out underlying conditions. You may also have to alter your pet's diet so that she doesn't suffer from ulcers in the future. Stomach ulcers can cause your pet a lot of discomfort, but with proper care and medication, your cat will enjoy good health for years to come.
