My cat is having tremors after taking Piperazine. Is it an overdose?

Updated on September 23rd, 2025

Pet's info: Cat | Burmese | Male | neutered | 10 lbs

I think I overdosed my cat with Piperazine. He is having tremors. I am worried. He is 10 pounds 8 years old. He had about 2 doses as I thought he didnt eat the first one all the way. Now I am extremely worried I measured wrong and that he is overdosing. He is just very needy right now and has spasms.

The toxic dose for this drug is quite high, but what you are describing definitely sounds like toxic reaction and requires emergency veterinary care to prevent Luis from getting worse. The veterinarian will likely want to have him on IV fluids and keep him for observation over the next 24 hours, since this is the most critical time.

There is really nothing you can do for him at home, so it's best to get him to the vet as soon as possible. Also, I would consider not using piperazine again in any of your pets. This is an outdated drug.

Good luck and I hope Luis gets better soon.
