Beta-Blocker Tablets for Cardiac Arrhythmias and Heart Disease in Small Pets Product Description Atenolol 25mg Tablets are a prescription cardioselective beta-1 adrenergic receptor blocker used by veterinarians to manage heart disease, arrhythmias, and high blood pressure in cats, small dogs, and ferrets. It works by sitting on beta-1 receptors in the heart, bringing the heart rate down, lowering blood pressure, easing the oxygen demands on the heart muscle, and slowing electrical conduction through the AV node. The 25mg strength suits cats and small dogs where the 50mg tablet would need splitting, covering hypertrophic cardiomyopathy, supraventricular arrhythmias, atrial fibrillation, and systemic hypertension off-label across all veterinary species. Benefits Feline HCM Management: A go-to option for hypertrophic cardiomyopathy in cats, pulling myocardial oxygen demand down and supporting better ventricular filling. Arrhythmia Rate Control: Keeps supraventricular tachycardias, atrial fibrillation, and premature complexes in check by slowing AV node conduction in cats and dogs. Small Pet Dosing Accuracy: The 25mg strength gives more room for precise low-end dosing in cats and small dogs where even half a 50mg tablet can land off target. Hypertension Control: Brings systemic blood pressure down by reducing cardiac output in cats and small dogs with hypertension under veterinary care. Ferret Cardiac Support: Goes into ferret management plans for left ventricular hypertrophy and certain arrhythmias under an exotic animal veterinarian's guidance. Ingredients Active Ingredients Atenolol How to Use Atenolol 25mg Tablets are a prescription-only medication. A valid veterinarian prescription is required to purchase this product. Please follow your veterinarian's specific instructions for the dosage and administration of this medication for your pet. Disclaimer: Dosage and administration of this medication must be determined by a licensed veterinarian. Always consult your veterinarian before administering or adjusting any prescription medication for your pet. Hiding this tablet inside a soft pill pocket or pill wrap treat makes administration much easier for both you and your pet, particularly for cats. Shop Pill Pockets for Dogs | Shop Pill Pockets for Cats Additional Information Precautions Never Stop Abruptly: Cutting this medication off suddenly can significantly worsen the underlying cardiac condition and set off dangerous arrhythmias, so always work with a veterinarian to taper gradually. Avoid in Congestive Heart Failure: Pets in acute or decompensated congestive heart failure, severe bradycardia, or significant AV block should not receive this medication. Avoid in HCM With Active Failure: Cats with hypertrophic cardiomyopathy actively going through left-sided congestive heart failure should not be given atenolol. Caution in Respiratory Disease: Cats or dogs with asthma or bronchospastic airway disease need careful management, as beta-blockers can make bronchoconstriction worse even at low doses. Caution in Diabetic Pets: This medication can cover up signs of low blood sugar and interfere with accurate glucose monitoring in diabetic cats and dogs. Avoid Before Surgery: Any planned surgical procedure needs to be discussed with a veterinarian while the pet is on atenolol, as it may interact with anesthetic agents. Drug Interaction Risk: Share a full list of your pet's current medications, including calcium channel blockers, phenothiazines, and other cardiac drugs, with your veterinarian before starting atenolol. Possible Side Effects Lethargy and Low Energy: Tiredness, low mood, and general weakness from a reduced heart rate are among the most commonly seen reactions in cats and dogs. Digestive Upset: Vomiting and diarrhea can come up, particularly at the start of treatment, and tend to be mild and short-lived. Dangerously Slow Heart Rate: Labored breathing or collapse from bradycardia is a serious reaction that needs immediate emergency veterinary attention. Hypotension: Weakness or fainting from low blood pressure needs prompt veterinary assessment and a possible dose adjustment. Peripheral Circulation Issues: Existing peripheral arterial circulatory problems can worsen in some dogs and may call for a reassessment 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 chip away at the tablet's potency, so a dry, shaded storage spot is the right choice. Out of Reach: Keep this medication somewhere children and untreated animals in the home cannot get to it.

Frequently Asked Questions Q1: Why is the 25mg atenolol tablet particularly important for cats? Ans: Cats on atenolol for hypertrophic cardiomyopathy or hypertension typically need amounts well below what a 50mg tablet delivers, and the 25mg size makes accurate low-end dosing possible without constantly splitting or quartering. Getting the dose right matters especially in cats given their small body mass and how sensitive they are to cardiovascular medications. A veterinarian will pin down the exact dose based on weight and cardiac status. Q2: How will my veterinarian monitor my cat's response to atenolol 25mg? Ans: Resting heart rate, blood pressure readings, echocardiography, and periodic electrocardiography all feed into whether atenolol is keeping cardiac rate and rhythm where they need to be. In cats with HCM, repeat echocardiograms track what is happening with ventricular wall thickness and overall cardiac function over time. What those objective measurements show is what drives any dose adjustments, not how the cat looks from the outside. Q3: Can atenolol 25mg be used in ferrets with heart disease? Ans: Atenolol is used off-label in ferrets for left ventricular hypertrophy and certain cardiac arrhythmias. Dosing and monitoring in ferrets run on different parameters than in cats and dogs, so this should only be handled by a veterinarian with exotic animal and cardiology experience. A veterinarian familiar with ferret cardiac disease will assess whether atenolol fits the specific condition. Q4: Can atenolol be used in cats alongside amlodipine for blood pressure control? Ans: Atenolol and amlodipine are sometimes paired in cats that need both heart rate control and blood pressure reduction, particularly where hypertrophic cardiomyopathy and hypertension are both in the picture. Since both pull blood pressure down, the combination needs close watching to make sure it does not push things too low. A veterinarian or veterinary cardiologist will keep a close eye on how that pairing plays out. Q5: What should I watch for at home in a cat receiving atenolol 25mg? Ans: A cat that seems more tired than usual, goes off food, starts hiding, breathes harder, or becomes less active is showing signs that something may be off with heart rate or blood pressure. When a sleeping cat's breathing rate creeps above 30 breaths per minute, that can mean fluid is accumulating and a veterinarian should hear about it quickly. Never adjust or stop the dose without speaking to a veterinarian first. Show more
