My 8 year old doberman female, 75 lbs ate a 10 mg cyclobenzaprine

Customer Question

My 8 year old doberman female, 75 lbs ate a 10 mg cyclobenzaprine that I dropped. This was on Sat. She slept approx 12 hrs and woke up groggy. Now the next day she is still very slow and not very responsive to her name or commands. Will this wear off or has my dog been damaged

Aloha! You're speaking with Dr. Michael Salkin
While cyclobenzaprine (Flexeril) is poorly tolerated by dogs causing depression, ataxia ("drunken sailor"), and weakness at as little as 0.13 mg/lb, no lasting adverse effects are expected. Poni ingested 10 mg/75lbs = 0.13 mg/lb - the lowest dose expected to cause adverse effects which gives him a very good prognosis for complete recovery shortly. We don't have pharmacokinetic studies of this drug in dogs and so I can't tell you how quickly it will be excreted but, historically, my patients have normalized within 48 hours.
Please respond with further questions or concerns if you wish.

It's been almost 48 hrs and she is still very lethargic. Didn't respond to doorbell,unusual for any dog lol. She will chase ball but only for short time and seems still wobbly on her legs. What is the potential for permanent damage to her. Thank you

You're quite welcome. I've never seen permanent damage occur from this drug in dogs. Just the fact that she'll chase a ball at all tells me that she's going to do nicely. Please continue our conversation if you wish.
