Cyproheptadine and Cat Appetite Stimulant

Cyproheptadine, also known as Periactin, is an antihistamine that can be prescribed for feline asthma and allergies. However, it also has been found to stimulate a cat's appetite.

  1. Cyproheptadine as an Appetite Stimulant

    • Cyproheptadine blocks serotonin, which causes anorexia at high levels. According to a 2000 study in Madrid, Spain, humans with high-waste products in their blood because of kidney problems may experience a loss of appetite due to high serotonin levels. Cats with chronic renal failure are often prescribed cyproheptadine with success.

    Side Effects

    • Side effects include drowsiness, dry mouth, constipation, hyperexcitability and howling. In addition, cyproheptadine can cause reduced urination, high temperature, and rapid heart rate and respiration.

    Caution

    • Cyproheptadine should be used with caution in cats with such chronic diseases as liver, kidney and heart failure. It should also be used with caution in cats with glaucoma and those who have suffered urinary obstruction.

    Other Medications

    • Cyproheptadine should be used cautiously in cats taking other medications.

      A number of medications, such as antidepressants, sedatives and drugs that treat blood pressure, may affect how cyproheptadine works. Interactions are also possible with cat flea and tick collars.

    Dosage

    • Cyproheptadine should be given to a cat only if prescribed by a veterinarian. Cats with certain conditions, such as renal failure, should start on a reduced dosage because the drug may build up within their bodies.
