Is Bupropion (Wellbutrin) Safe for Cats?
Why it’s a problem
Bupropion is a stimulating antidepressant that lowers the seizure threshold, and cats are especially vulnerable because of their small size. Reported signs include tremors, racing heart rate, fever, and seizures. Even a single human tablet can be a severe exposure for a cat.
How to keep your pet safe
Keep bupropion in secure, closed storage and check for dropped pills — cats bat loose tablets under furniture and find them later. Antidepressants should never be shared with pets.
Warning signs to watch for
Vomiting, agitation, vocalizing, tremors, dilated pupils, rapid breathing, fast heart rate, fever; serious cases: seizures, rigidity, collapse.
When to call the vet
Call your veterinarian or a pet poison hotline immediately. Because seizures are a known risk, professional evaluation is needed even when the amount eaten seems small.
Common questions
My cat may have swallowed one of my bupropion tablets — what do I do?
Treat it as an emergency — bupropion can cause seizures in cats at low doses. Call your vet or a pet poison hotline now with the tablet strength.
Can cats take human antidepressants?
Not without a veterinary prescription. Some drugs are adapted for cats, but human strengths and formulations are unsafe to share.
