Ask a Dog Vet and Get Answers to Your Dog Health Questions
Greetings, I’m Dr. Peck, a small animal veterinarian in general practice. Hopefully I might be of some help. One moment while I reply…
Disclaimer: This communication is for discussion purposes only. Without seeing an animal in person, a valid veterinary-client-patient relationship does not exist, and therefore I am unable to diagnose, prognose, or treat. Any comments made during discussion here are based on the information provided and are simply my thoughts regarding what I’d be considering were this type of case presented to me in person. The BEST recommendation for ANY veterinary-related concern is to seek veterinary assessment in person with your local veterinarian.
Can you tell me how many mg (milligrams) the pills are?
Ok, one moment while I do a quick calculation...
20mg /54kg = 0.37mg/kg
This medication is typically prescribed for dogs at 0.5mg/kg once to twice daily. This is under the therapeutic range. No toxicity would be anticipated at this dosage. I would take no action.
I'm assuming the "no" was in response to the website prompting you to do a phone call - apologies, it offers that automatically, discussing here is fine.
Let me know if you have any follow-up questions, simply write me back! Otherwise, please be sure to kindly rate using the stars, so that I receive credit for helping with your question today (this is how professionals on this site are compensated for their time). Thanks! – Dr. Peck.
Yes, apologies I'm typing...
Flexeril (cyclobenzaprine) is not typically well tolerated in dogs in general and thus I don't recommend administering it with or without recently ingesting the ace inhibitor / lisinopril.
Duration of action of lisonopril in dogs is around 24 hours, with peak blood levels after 4 hours post ingestion. It should be "out of his system" after a day.
For muscle relaxation dogs are typically prescribed methocarbamol - it is very well tolerated, consider asking your local veterinarian about this medication for the muscle spasms you've described.
You are very welcome. :) Kindly remember to rate with the stars, that is the best way to thank the professionals that use this site. Thanks! - Dr. Peck.
