Atenolol is a beta blocker for pets used for high blood pressure and certain heart conditions. Learn how it works, monitoring, and safety.
Quick answer
Atenolol is a prescription beta blocker used in dogs and cats to manage high blood pressure and certain heart conditions. It is not a cure and must be given exactly as your veterinarian directs, with regular monitoring. Never adjust the dose without veterinary guidance.
What conditions does atenolol treat in pets?
Atenolol is used to manage high blood pressure and various heart conditions in dogs and cats. It may be prescribed for feline hypertrophic cardiomyopathy, a common heart disease in cats, or for other cardiac issues where reducing heart rate and workload is beneficial. Your veterinarian will determine if it is appropriate based on a full cardiac evaluation.
How is atenolol dosed for dogs and cats?
Dosing is highly individualized based on species, weight, the condition being treated, and response to therapy. There is no standard one-size-fits-all dose. Your veterinarian will calculate the correct amount and frequency. Atenolol tablets are available in various strengths, so follow the prescription label exactly and use a pill cutter if needed for accurate dosing.
What side effects should I watch for?
Common side effects may include lethargy, weakness, or gastrointestinal upset. More serious but less common effects include slow heart rate, low blood pressure, or difficulty breathing. Contact your veterinarian if you notice any concerning changes, especially after starting the medication or changing the dose.
Can atenolol be stopped suddenly?
No. Suddenly stopping a beta blocker can worsen the underlying condition or cause rebound effects. Always consult your veterinarian before discontinuing or changing the dose. They may taper the medication gradually to avoid complications.
How should I store and handle atenolol tablets?
Store atenolol tablets at room temperature, away from moisture and heat. Keep them out of reach of children and pets. Wash your hands after handling. Do not use expired medication; check the expiration date and dispose of properly.
