Atenolol is a prescription medication used to treat certain heart conditions such as arrhythmias. This beta-blocker can also be used to lower blood pressure and treat enlarged hearts in cats. Atenolol functions by slowing and regulating your pet’s heart rate to make the heart work more efficiently. It is appropriate for use in dogs, cats, and ferrets.
Atenolol is a beta-blocker that lowers heart rate, blood pressure, and over-activity of the heart, thus allowing for a regular heartbeat and better heart function.
Atenolol is the generic alternative to Tenormin.
Side Effects and Warnings
Side effects may include lethargy, difficulty exercising, low blood pressure which would cause fainting, weakness, or dizziness, loss of appetite, nausea, diarrhea, behavior change, and low blood sugar.
Atenolol may constrict the bronchi, resulting in coughing, wheezing, or difficulty breathing.
An improper dose of Atenolol can cause the heart rate to be too slow.
If your pet experiences an allergic reaction (symptoms may include swelling, hives, difficulty breathing, itching, etc.) or any of the above symptoms, contact your veterinarian.
Atenolol should not be used in pets with heart block, bradycardia (slow heart rate), and some types of heart failure. Use with caution in diabetic pets or those with kidney disease.
Use with caution in animals with some types of lung disease such as asthma.
Atenolol should not be used in pets allergic to it, or pets who have had reactions to other beta-blockers.
