Hi there. There are no reported contraindications to using methocarbamol with vetmedin, enalapril, or thyroxine. They should all be fine when used together. Best of luck and thank you for using Pet Coach.

Hello, thank you for using PetCoach. 500mg is a pretty high dose of Methocarbamol for a 10 pound dog. At the very high end of the "normal" dosing range the dose would be 200mg. That being said, luckily the drug is very safe even at high doses. He probably just needs to sleep it off. DO NOT give him any more medication until you speak to your vet. If he starts vomiting or the sleeping lasts more than a total of 24 hours then you need to take him to your vet or to the ER. As always, if you are really worried at this time you should take him to the ER for an exam. You know him best so if you. are worried you should act on that. Here is a link to an article about this medication's use in dogs: ( https://www.petplace.com/article/drug-library/drug-library/library/methocarbamol-robaxin-v-for-dogs-and-cats/ ) Hope this helps. Best wishes.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Brody. I'm sorry he's in pain. Initially, it can be dosed at 7-20mg per pound. At his weight, that's 1,225mg to 3,500mg. You gave him 1000mg, which is actually below the recommended dose range. You did not overdose him, and things will be ok. I hope this helps!

Use caution. The methocarbamol is a muscle relaxant and has some sedative effects. The Benadryl, as an antihistamines, can be sedating as well. Given together, they may cause extreme lethargy or sedation. Discuss your concerns with your vet prior to administering this combination of medications.

Thanks for using Petco Pet Education Center, formerly Petcoach! Normally, it is safe to administer these medications together. However, I do not recommend that you administer any medications if they have not been prescribed by a veterinarian as some of these medications can cause side effects and pre-screening bloodwork should be performed. Good luck and have a good night!
