Famotidine For Dogs: How It Works

Famotidine For Dogs: How It Works

Famotidine For Dogs: Famotidine is an antacid medication used to reduce stomach acid in dogs. It works by blocking histamine receptors in the stomach that stimulate acid secretion.

Famotidine is in a class of drugs known as H2 blockers. It works by blocking histamine receptors (known as H2 receptors) in the stomach lining that normally trigger the release of stomach acid. By blocking these receptors, famotidine reduces the amount of acid in the stomach.

This helps relieve symptoms like vomiting, diarrhea, and loss of appetite caused by excess stomach acid. It can also help prevent ulcers from forming or stop ulcers that have already formed from getting bigger. Famotidine starts working within 1-2 hours and its effects can last for up to 10-12 hours.

Famotidine For Dogs: How It Works

Famotidine works by reducing the amount of acid in your dog’s stomach. Specifically, it blocks the histamine H2 receptors that stimulate acid secretion in the stomach. By blocking these receptors, famotidine inhibits the production of stomach acid.

How it provides relief

Less stomach acid means less irritation of the stomach lining and tissues. This can help relieve symptoms like:

  • Nausea and vomiting
  • Loss of appetite
  • Stomach pain

Famotidine starts working within 1 to 2 hours and the effects can last for up to 12 hours. The typical dosage for dogs is between 0.5 to 1 mg per pound of body weight, given once or twice a day. You’ll want to follow your vet’s dosage instructions based on your dog’s condition.

When to Give Your Dog Famotidine

When should you give your dog famotidine? This medication is usually given once or twice per day, depending on your vet’s recommendation based on your dog’s condition. Some common reasons for prescribing famotidine for dogs include:

1. Gastrointestinal Issues

If your dog is suffering from excess stomach acid, ulcers, or acid reflux, famotidine can help reduce symptoms like nausea, vomiting, and pain. It works by decreasing the amount of acid in the stomach. For conditions like this, famotidine is often given daily to prevent excess acid buildup.

2. Allergic Reactions

For dogs with food allergies or other allergic reactions, famotidine can help reduce inflammation in the stomach and intestines. If your dog has eaten something he’s allergic to, your vet may prescribe a short course of famotidine to calm symptoms like itching, swelling, and digestive upset until the allergen is out of his system.

Potential Side Effects of Famotidine For Dogs

Famotidine can cause some side effects in dogs, just like any medication. The good news is, most side effects are mild and temporary. However, it’s important to monitor your dog for any adverse reactions when they first start taking famotidine or if the dosage is increased.

1. Decreased Appetite

Famotidine may cause a decrease in appetite or nausea in some dogs. This is usually temporary, but if your dog’s appetite does not return to normal within a couple of days or your dog seems very nauseous, contact your vet. They may recommend giving the medication with food, dividing the dosage, or switching to another acid reducer.

2. Diarrhea or Constipation

Stomach acid plays an important role in digestion, so reducing it may lead to changes in bowel movements. Your dog may experience loose stools, diarrhea, or even constipation. Make sure your dog has access to plenty of water to stay hydrated. If the problem persists for more than a couple of days, talk to your vet about adjusting the dosage or switching medications.

3. Fatigue or Lethargy

Famotidine can make some dogs drowsy or tired. This is usually temporary, but use caution when first starting the medication or increasing the dosage. Avoid activities that require balance, coordination or alertness until you know how your dog will respond.

4. Allergic Reaction

Though rare, some dogs may have an allergic reaction to famotidine. Watch for symptoms like hives, rash, itching, swelling of the face, lips, tongue, and throat or other areas of the body. Also watch for wheezing, trouble breathing, collapsing. Seek emergency vet care immediately if a reaction occurs.

The benefits of famotidine for treating stomach issues often far outweigh the risks of potential side effects. However, close monitoring when your dog first starts taking this medication or any time the dosage is increased will help ensure maximum benefit and minimal risk. Always talk to your vet if you have any concerns about side effects from famotidine or if they seem severe or long-lasting.
