Product Info

Metoprolol Tartrate (Lopressor or Toprol XL), is used for treatment and prevention of cardiac arrhythmias in dogs and cats as well as hypertension (high blood pressure) and hypertrophic cardiomyopathy in cats.

The primary use of metoprolol is treatment (and sometimes prevention) of cardiac arrhythmias. Commonly treated heart-rhythm disturbances include atrial fibrillation, atrial flutter, supraventricular tachycardia and premature ventricular complexes (PVCs). Metoprolol reduces cardiac output and lowers high blood pressure (systemic hypertension).

Metoprolol is also "cardioprotective," which means it protects the heart muscle from damage in chronic heart muscle disease. This benefit is sometimes used to treat dogs with dilated cardiomyopathy (heart muscle disease).

Side Effects

While generally safe and effective when prescribed by a veterinarian, metoprolol can cause side effects in some animals. Metoprolol may interact with other medications. Consult with your veterinarian to determine if other drugs your pet is receiving could interact with metoprolol. Such drugs include furosemide, insulin and calcium channel blockers drugs (diltiazem, verapamil, amlodipine).


This drug is not approved for use in animals by the Food and Drug Administration but it is prescribed for off-label use by veterinarians as an extra-label drug.

Metoprolol should not be used in animals with known hypersensitivity or allergy to the drug. Metoprolol may cause some animals to become weak due to a slow heart rate or low blood pressure. Rarely, a pet may faint.
