Is Amlodipine (Norvasc) Safe for Cats?
Why it’s a problem
Amlodipine is actually used in cats for hypertension, but cat doses are tiny compared with human tablets. Ingestion of human tablets has been reported to cause profound low blood pressure, weakness, and collapse in cats. A single tablet can be many times a feline dose.
How to keep your pet safe
Keep amlodipine in secure storage — a tablet on the floor is easy for a cat to find and swallow. Never share your own prescription; feline dosing requires a veterinarian.
Warning signs to watch for
Profound lethargy, weakness, wobbliness, vomiting, pale gums, fast or slow heart rate; severe cases: collapse, fainting, cold extremities.
When to call the vet
Call your veterinarian or a pet poison hotline immediately — low blood pressure can persist for hours. Report the tablet strength and the maximum number possibly eaten.
Common questions
My cat ate one of my amlodipine tablets — will she be OK?
Not without assessment — one human tablet can crash a cat’s blood pressure. Call your vet or a pet poison hotline right away with the strength and your cat’s weight.
Isn’t amlodipine given to cats anyway?
Yes, at very small veterinary doses for high blood pressure. Human tablets are many times stronger — never substitute your own prescription.
