My dog ate a 4 mg zanaflex, she weighs between 50-60 pounds and had just eaten her regular dinner. What should I do?
Does she need fluids and/or other poison treatments, purge, activated charcoal?

Hello,

I am sorry to hear you are worried about Katie. How long ago did she get the pill?

Expert:  Rebecca replied 1 year ago.

I am a veterinarian and will do my best to help. If she is 50 pounds, she got .17 mg of Zanaflex per kilogram (2.2 pounds) of body weight. We calculate all toxicities in mg per kg. I checked with a toxicologist; we see low heart rate, vomiting, walking like drunk, and low blood pressure at .01 mg per kg, she you might see some of these symptoms. If she got in less than an hour ago, you could try to induce vomiting by giving her 1/2 tablespoon of hydrogen peroxide in some milk or ice cream. It does not always get a dog to vomit.

If she does show symptoms, your vet would have an antidote, called Antisedan, that would help.

Sorry,I misplaced a decimal! We see symptoms at .1 mg per kg, not .01. So she got a slightly higher dose, at .17 mg per kg.
