If your dog has GERD (known as gastrointestinal reflux disease), gastritis, esophagitis, or stomach ulcers, your vet will probably prescribe Famotidine for dogs.

Your vet will likely ask you to buy the tablets at a particular strength and dose your dog accordingly with half, one, or more pills.

Which Is Better for Cats: Famotidine or Omeprazole?

In general, Famotidine is usually preferred as a first-line treatment for mild cases of acid reflux and stomach ulcers in cats, while Omeprazole is usually reserved for more severe cases or when Famotidine alone is not effective. However, the decision on which medication to use should be made by a veterinarian who has examined the cat and understands their medical history and current condition.

Can You Give Human Famotidine to Cats?

Giving human famotidine to cats without first seeing a veterinarian is not advised. While famotidine is safe for cats when given in appropriate doses, the dose for humans differs from that for cats. Additionally, human medications may contain other ingredients that could harm cats.

How Much Famotidine Can I Give My Dog?

Famotidine for dogs should generally be administered twice a day at a dose of 0.25 to 0.5 mg per pound of body weight. This means that a 20-pound dog would typically receive a dose of 5 to 10 mg of famotidine twice daily.

Is Famotidine an Antacid?

Famotidine is not technically an antacid. Instead, a drug called an H2 receptor antagonist does the trick by preventing histamine from affecting the acid-producing cells in the stomach lining. By blocking this action, famotidine can reduce the acid produced in the stomach. It can help to treat conditions such as gastroesophageal reflux disease (GERD), heartburn, and stomach ulcers. Antacids, on the other hand, are a medication that works by neutralizing stomach acid that has already been produced. They do not reduce the amount of acid the stomach produces but provide temporary relief by neutralizing the already there acid.

Is Famotidine Safe for My Petโ€™s Kidneys?

Famotidine 10mg for dogs or cats is generally considered safe for use in dogs and cats with normal kidney function, but as with any medication, there is always a risk of side effects. In rare cases, famotidine may cause kidney problems in dogs and cats, such as acute interstitial nephritis (kidney tubular inflammation). If a dog or cat has pre-existing kidney disease or is taking other medications that can affect kidney function, the veterinarian may need to adjust the dose of famotidine or choose an alternative medication.

What Are the Side Effects of Famotidine?

Famotidine for dogs side effects includes headache, dizziness, constipation, diarrhea, nausea, vomiting, and abdominal pain. Rarely, famotidine may cause more serious side effects such as allergic reactions, acute interstitial nephritis (kidney tubular inflammation), or blood disorders. In rare cases, long-term use of famotidine may increase the risk of bone fractures, vitamin B12 deficiency, or pneumonia.

Does Famotidine Stop Vomiting in Cats?

Famotidine can help stop vomiting in cats, but its effectiveness in this regard may depend on the underlying cause of the vomiting. Famotidine for cats works by reducing the amount of stomach acid produced, which can help to reduce irritation and inflammation of the stomach lining that may be contributing to the vomiting.

How Long Can a Cat Take Famotidine?

The length of time a cat can take famotidine will depend on the specific condition being treated and the veterinarian's recommendation. In some cases, famotidine may be prescribed for short-term use, such as to treat an acute vomiting episode or help manage stomach ulcer symptoms. In other cases, famotidine may be prescribed for longer-term use, such as to manage chronic conditions like GERD or to prevent the recurrence of stomach ulcers.

Can Famotidine Be Crushed for Cats?

Famotidine tablets are best taken whole but can be crushed for cats if necessary, but it is essential to consult with a veterinarian to determine the appropriate dose and administration method. The crushed tablet can be mixed with a small amount of food or water to make it easier for the cat to swallow. However, it is important to note that not all medications can be crushed or mixed with food, as some medications may lose their effectiveness or cause irritation to the digestive tract if crushed.

Can You Stop Famotidine at Any Time?

Famotidine should not be stopped abruptly without first consulting with a veterinarian. In some cases, stopping famotidine suddenly can cause a rebound effect where stomach acid production increases and symptoms like heartburn or vomiting can worsen. In addition, stopping medication prematurely can lead to the underlying condition not being fully resolved and potentially leading to more severe or long-term problems.

Famotidine 20 mg

Famotidine exhibits the tendency to interact with other medications such as Digoxin and Ketoconazole. Famotidine should also be used with caution in pets that are pregnant or pets suffering from liver, kidney, or heart disease. Therefore, consult a veterinarian before administering Famotidine to your pet.

Famotidine could be responsible for certain side effects in animals. This drug should not be administered to animals with hypersensitivity or allergy. Famotidine should be prescribed with extreme caution in animals with kidney or liver disease.

Though side effects are rare with Famotidine, your pet may exhibit loss of appetite and tiredness. Contact your veterinarian if you observe these symptoms. You should also contact your veterinarian if your pet exhibits signs of an allergic reaction, such as swelling, hives, itching, or difficulty breathing.

Famotidine is not for use in animals allergic to it. Use with caution in geriatric animals or those with kidney, liver, or heart disease. Your pet may experience a temporary increase in stomach acid production when you discontinue use of Famotidine. Famotidine should be use with caution in pregnant animals.

Tell your veterinarian about any other medications, vitamins, or supplements that your pet is taking. Consult your veterinarian before using Famotidine in conjunction with antacids, sucralfate, digoxin, metoclopramide, or ketoconazole.

Famotidine is a pet prescription primarily used in the treatment of stomach (gastric) and intestinal ulcers. Gastric ulcer results in the break or erosion in the lining of the esophagus, stomach, or small intestines. The severity of the ulcer depends on the depth of the erosion.

An anti-ulcer drug, Famotidine belongs to the histamine receptor-2 blocker class. The secretion of gastric acid occurs when H-2 receptors present in the cell membranes of stomach cells are stimulated. By blocking the H-2 receptors, gastric acid will not be secreted, thus helping the ulcer heal.

Famotidine should be administered only under the supervision of a veterinarian. This drug also plays an important role in the treatment and/or prophylaxis of gastric, abomasal and duodenal ulcers, uremic gastritis, stress-related or drug-induced erosive gastritis, esophagitis, duodenal gastric reflux, and esophageal reflux. Famotidine also assists in the treatment of stomach inflammation caused by kidney failure and helps in combating acid reflux disease to reduce injury to the esoaddphagus. Dogs and cats suffering from mast cell tumors can be treated with Famotidine as these tumors could result in massive secretion of histamine.
