Is it ok to take muscle relaxants following Botox cosmetic?

Unless you have some drooping of the brow after botox, I do not see any problem in taking muscle relaxants after your injection.

As long as you are not allergic it should be fine, however it’s always a good practice to follow up with your doctor to be sure. 

Yes, as long as you take as directed there is no harmful interaction with the Botox. Keep in mind there is a small percentage of the population that find muscle relaxers addicting.  Use in moderation.  Best of luck, Dr. Giordano

I recommend following up with your injector about their protocols regarding muscle relaxants after a Botox treatment, but this should be fine. Keep in mind, it can take 1-2 weeks for final results with Botox. See an expert. Best, Dr. Emer
