Ranitidine decreases the amount of stomach acid produced.

For: Dogs, Cats & Horses


  • Decreases the amount of stomach acid produced
  • Aids in treatment and prevention of ulcers
  • Also used in the treatment of gastritis and esophagitis

  • Ranitidine is used to decrease the amount of stomach acid produced. This aids in the treatment of ulcers that are present and helps prevent ulcer formation. It is also used in the treatment of gastritis (inflammation of the stomach) and esophagitis (inflammation of the esophagus). It may also stimulate movement of food through the stomach and intestine.

    How it works

    Ranitidine works by blocking the effects of histamine. This prevents the cells in the stomach from producing stomach acid.


    Dosage & Administration

    Ranitidine tablets are given orally, without food. The injectible form may be given in the muscle (IM), subcutaneously (SC, subQ, under the skin), or intravenously (IV), as directed by your veterinarian.

    Possible side effects of Ranitidine: Side effects in pets are rare. When used in humans, mental confusion may be seen.

    If your pet experiences an allergic reaction to the medication, signs may include facial swelling, hives, scratching, sudden onset of diarrhea, shock, seizures, pale gums, cold limbs, or coma. If you observe any of these signs, contact your veterinarian immediately.

    If you miss giving a dose: If you miss a dose, give it as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to the regular schedule. Do not give two doses at once.

    If you overdose the pet: May see muscular tremors and an increased breathing rate. If you know or suspect your pet has had an overdose, or if you observe any of these signs in your pet, contact your veterinarian immediately.

    What should I avoid while giving Ranitidine to my pet: Notify your veterinarian of any other medications, including vitamins and supplements, your pet is taking while receiving Ranitidine.

    If used with antacids, give the Ranitidine two hours before or two hours after the other medication(s).

    Consult your veterinarian before using ranitidine with procainamide, ketoconazole, or propantheline bromide, since interactions may occur.

    May cause a falsely positive laboratory test for protein in the urine.

    Who should not take it? Not for use in pets hypersensitive (allergic) to Ranitidine. Use with caution in pets with heart, liver, or kidney disease. Do not use in pregnant or lactating pets unless benefits outweigh the risks.

    This medication should only be given to the pet for which it was prescribed.
