Is Amitriptyline (Elavil) Safe for Cats?
Why it’s a problem
Tricyclic antidepressants can cause rapid heart rate, arrhythmias, fever, and seizures in cats, whose small size leaves little margin. Although amitriptyline is occasionally prescribed for cats with overgrooming or anxiety, human tablets are vastly stronger than a feline dose. Accidental ingestions are considered emergencies in this species.
How to keep your pet safe
Store amitriptyline in a closed cabinet and sweep up any dropped pills immediately. If your cat overgrooms or seems anxious, get a veterinary prescription rather than sharing your medication.
Warning signs to watch for
Vomiting, drooling, profound lethargy or agitation, dilated pupils, rapid or irregular heartbeat, rapid breathing, fever; severe cases: tremors, seizures, collapse.
When to call the vet
Call your veterinarian or a pet poison hotline at once — cats can develop heart-rhythm problems quickly after a tricyclic overdose. Bring the bottle so the strength and amount can be assessed.
Common questions
My cat chewed one of my antidepressant tablets — is it urgent?
Yes — amitriptyline can affect a cat’s heart within hours. Call your vet or a pet poison hotline immediately, even if your cat looks fine.
Do vets use amitriptyline for cats?
Sometimes, for behavior problems, but only at tiny cat-specific doses with monitoring. Never self-dose — your own prescription is far too strong.
