Famotidine for Chronic Digestive Issues in Dogs: What You Need to Know

It is essential to choose good dog food because dogs frequently experience digestive disorders, which, if addressed, can result in major health complications. Famotidine is a medication that can be used to treat chronic digestive issues in dogs. 

The global Famotidine market is expected to grow at a CAGR of 5.5% between 2022 and 2030, according to a report by Dataintelo. The report also mentions that in 2020, North America held the largest revenue share in the global market and is expected to maintain its dominance during the forecast period. This is due to the product’s high demand in the region.

In this article, we will discuss what Famotidine is, how it works, and what you need to know before giving it to your dog.

What is Famotidine

Famotidine is a medicine that belongs to the histamine-2 blocker class of medications. It is frequently used in dogs to treat stomach and intestine ulcers, stomach acid reflux, and other digestive disorders. Famotidine is available in tablet, capsule, and injectable forms.

Famotidine is typically prescribed to treat gastrointestinal conditions such as gastroesophageal reflux disease (GERD), peptic ulcer disease, and Zollinger-Ellison syndrome. It can also be used to manage symptoms of heartburn, indigestion, and sour stomach. Famotidine may be recommended as part of a combination therapy alongside other medications to treat certain conditions.

Purchasing Famotidine

One of the most convenient options for purchasing Famotidine is through an online pet pharmacy like PetCareRx, which offers a wide selection of pet medications at fair prices. Plus, their team of licensed veterinarians and pharmacists is available to answer any questions you may have about your pet’s medication, including common questions such as “what is Famotidine used for in dogs?” 

When ordering Famotidine, it is critical to confirm that you are obtaining genuine medicine from a reliable provider. Stick to well-known pharmacies, and check that the medication you receive matches the prescription from your veterinarian.

How Does Famotidine Work?

Famotidine acts by inhibiting histamine synthesis in the stomach. This histamine-2 blockade aids in lowering the quantity of acid generated in the stomach. This reduction in acid production can help to reduce the symptoms associated with acid reflux, ulcers, and other digestive issues.

In addition, Famotidine can also help to improve the effectiveness of other medications used to treat digestive issues, such as antibiotics and anti-inflammatory drugs. By reducing the acidity of the stomach contents, Famotidine can improve the absorption of these medications and help them to work more effectively.

Side Effects 

Like all medications, Famotidine can cause side effects. Famotidine’s most frequent adverse effects include diarrhea, vomiting, lack of appetite, sleepiness, lethargy, and disorientation. These adverse effects are often minor and resolve on their own.

Famotidine can cause more significant adverse effects, including liver or kidney damage, in rare situations. Jaundice, dark urine, or odd behavior are signs of these more significant side effects. If you notice any signs of these more serious side effects, you should seek emergency veterinary care.

It is important to administer Famotidine to dogs carefully, as an overdose can be harmful. According to a 2023 article on petMD, an overdose might cause low blood pressure, a rapid heart rate, and collapse. In case of a suspected overdose, it is crucial to seek immediate veterinary care, contact a veterinarian, or reach out to an animal poison control center.

Famotidine Dosage

When prescribing Famotidine for dogs, the appropriate dosage will be determined based on the severity of the digestive issue and the weight of the dog. A blog post on Pettable states that Famotidine pills are available in doses of 10, 20, and 40 mg, and the powder form must be measured to ensure correct dosing. The recommended dosage for dogs is typically between 0.22 to 0.44 mg per pound of body weight.

Famotidine can be given with or without food, but it is usually recommended to give it with food to help reduce the risk of side effects. It is also important to give Famotidine at the same time each day to ensure that the medication is working effectively.

Giving Famotidine With Other Medications

Famotidine can be used in conjunction with other drugs, but you should always check with your veterinarian before administering any new medication to your dog. Famotidine may interact with some medications, including antacids, sucralfate, and ketoconazole. Your veterinarian can advise you on the best way to give Famotidine with other medications to ensure that they are working effectively and safely.


In conclusion, Famotidine is an effective medication for treating chronic digestive issues in dogs. It works by blocking the production of histamine in the stomach, which reduces acid production and can alleviate symptoms associated with digestive issues. While Famotidine is generally safe for dogs, it can cause side effects, and overdoses can be harmful. 

When administering Famotidine to dogs, it’s important to follow the correct dosage instructions and give it at the same time each day. Additionally, it’s essential to consult with a veterinarian before giving your dog any new medication and to purchase the medication from a reputable source.
