General Description

Ranitidine is a histamine (H2) blocker that is used to prevent and treat stomach and intestinal ulcers in cats and dogs. It is often prescribed in the cases of gastritis and in the management of acid reflux disease to soothe inflammation and assist in healing. It also assists in stimulating the passage of food through the digestive tract.

Give this medication without food, as food will decrease it’s effectiveness.

How It Works

Histamine is a key component in the allergic reaction, causing inflammation and swelling. It can often cause stomach cramping and diarrhea as well. By inhibiting the H2 receptor, a receptor for histamine, Ranitidine reduces the output of stomach acid. This reduces the pH of the digestive system, giving the ulcer in the stomach time and a more favorable environment to rest and heal.

Storage Information

Store in a tight container at room temperature protected from light and heat.

Missed Dose?

Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
