Beta-Blocker Tablets for Heart Disease and Hypertension in Pets Product Description Atenolol 50mg Tablets are a prescription beta-blocker cardiac medication used by veterinarians for dogs, cats, and ferrets. It works by binding to adrenaline receptors in the heart, which slows the heart rate, brings blood pressure down, and reduces how hard the heart has to work. It is used for abnormal heart rhythms, high blood pressure, hypertrophic cardiomyopathy in cats, and obstructive heart diseases in dogs, and is used off-label in veterinary practice. Benefits Arrhythmia Control: Treats abnormal heart rhythms including atrial fibrillation, supraventricular tachycardia, and premature ventricular complexes in dogs and cats. Blood Pressure Reduction: Brings systemic high blood pressure down by easing cardiac output and heart rate in dogs, cats, and ferrets. HCM Management in Cats: Helps keep hypertrophic cardiomyopathy in check by cutting down on myocardial oxygen demand and supporting heart efficiency. Obstructive Heart Disease: Used in dogs for pulmonic stenosis and subvalvular aortic stenosis by taking some of the workload off the heart. Minimal Liver Metabolism: Goes through very little liver processing and leaves the body mainly through urine, making it a better fit for liver-compromised pets.

Not for Heart Failure: Pets in active congestive heart failure, with severe bradycardia, or with greater than first-degree heart block should not receive this medication. Avoid in HCM With Failure: Cats already going through left-sided heart failure from hypertrophic cardiomyopathy should not be put on atenolol. Caution With Lung Disease: Pets with asthma or bronchospastic lung disease need extra care, as this class of medication can make breathing harder. Caution With Diabetes: This medication may get in the way of reliable blood sugar tracking and can hide low blood sugar signs in diabetic pets. Avoid Before Surgery: Starting atenolol ahead of a surgical procedure is not recommended, as it may interact with the anesthetic agents involved. Drug Interaction Risk: Share a full list of your pet's current medications, including sympathomimetics, phenothiazines, and other cardiac drugs, with your veterinarian before starting. Possible Side Effects Low Energy and Weakness: Low energy, low mood, and weakness tied to a slower heart rate are among the more commonly seen reactions in pets on atenolol. Digestive Upset: Vomiting and diarrhea can show up, particularly early in treatment, and tend to be mild and short-lived in most pets. Very Slow Heart Rate: A heart rate that drops too low and causes breathlessness or collapse is a serious reaction that needs immediate veterinary attention. Low Blood Pressure: Some pets on this medication develop low blood pressure that shows up as weakness or fainting, both of which need veterinary review. Peripheral Circulation Issues: In some dogs, atenolol can worsen existing peripheral arterial circulation problems, which may prompt a review of the treatment plan. Storage Information Room Temperature: Tablets do best at room temperature inside a tightly closed container, kept away from excess heat and humidity. Protect From Moisture and Light: Direct sunlight and damp conditions can affect how well the tablets hold up, so a dry, shaded storage spot works best.

Frequently Asked Questions Q1: What heart conditions does atenolol treat in dogs and cats? Ans: Atenolol is used for abnormal heart rhythms, high blood pressure, hypertrophic cardiomyopathy in cats, and obstructive heart diseases in dogs.

Q2: Can atenolol be stopped suddenly in dogs and cats? Ans: No, stopping this medication without a gradual taper can leave the underlying heart condition in a worse state and may set off dangerous cardiac events. Your veterinarian will put together a step-down plan to bring the dose down safely when the time comes. Q3: Is atenolol safe for cats with hypertrophic cardiomyopathy? Ans: Atenolol can help manage hypertrophic cardiomyopathy in cats by bringing down heart rate and oxygen demand. It should not be used in cats already in left-sided heart failure. A veterinarian will decide whether atenolol is the right fit based on your cat's specific cardiac status. Q4: What are the most common side effects of atenolol in pets? Ans: Low energy, low mood, and weakness from a slower heart rate are what pets most often go through on this medication. Vomiting and diarrhea can also come up, especially early on.

Ans: Yes, atenolol can be affected by sympathomimetic drugs like epinephrine and phenylpropanolamine, phenothiazines, anesthetic agents, and other cardiac medications. Give your veterinarian a full picture of every medication, supplement, and vitamin your pet is on before starting atenolol.
