Cat & Dog - Propranolol

Why has my veterinary surgeon prescribed this medicine?

Propranolol is used to correct irregular heartbeat. Propranolol decreases the heart’s need for blood and oxygen and therefore reduces the amount of work the heart must do. This medication may be prescribed for other conditions as determined by your veterinary surgeon.

Propranolol is not available as a veterinary preparation. Your veterinary surgeon may ask you to sign a consent form so a preparation licensed for humans can be used to treat your pet.

How does this medicine work?

Propranolol is a non-selective beta-adrenoceptor blocking drug (beta-blocker), which antagonises (acts against)sympathetic activity. The heart rate is decreased as a result of reduction in the sinus node rate and prolongation of atrio-ventricular node conduction.
