HCM medicines are chosen for specific findings and complications. Two cats with the same diagnosis may need different treatment. This guide explains examples and questions for your vet; it does not recommend a prescription, dose or combination.
Examples of treatment purposes
- Reducing clot risk: clopidogrel reduces platelet aggregation and may be prescribed when the vet identifies a need for clot prevention.
- Managing fluid accumulation: diuretics such as furosemide may be used in congestive heart failure. They require a plan for monitoring hydration, kidney function and electrolytes.
- Addressing selected heart findings: drugs such as atenolol, or other cardiac medicines, may be considered according to heart function and the individual case.
The Tufts HeartSmart medication guide explains commonly used drugs. These examples are not a complete list, and a medicine appropriate for one patient may be unsuitable for another.
Ask your vet which treatment options are appropriate and available for your cat, including any newer options. Do not substitute human medicines or another animal’s prescription. Cornell describes how treatment depends on cardiac findings and complications.
Questions for every prescription
- What is this medicine intended to treat or prevent?
- What exact strength, amount and timing should I use?
- Should it be given with food, and are there storage instructions?
- What should I do after a missed or vomited dose?
- Which unwanted effects require a call or emergency care?
- Which rechecks or blood tests are needed, and when?
If giving medicine is difficult
Ask the practice to demonstrate administration. Before crushing a tablet, opening a capsule or changing to a compounded preparation, check that it is appropriate for that exact medicine. Keep a dose record where all carers can see it and keep medicines secured away from pets and children.
Monitoring response
Follow the agreed plan for breathing counts, appetite, weight and activity. Do not change or stop treatment based on a home reading without veterinary instructions. If you suspect a dosing error, contact the practice promptly with the medicine details.
Breathing difficulty, collapse or sudden painful limb weakness needs emergency assessment. Do not delay while trying to administer extra medicine or obtain a measurement.
