FAA Pathway: Do Not Fly (muscle relaxant) — AME must defer if used routinely

The FAA's Do Not Fly table lists muscle relaxants as a class ("including but not limited to" carisoprodol and cyclobenzaprine) because they can impair performance even when you feel alert. Methocarbamol (Robaxin) is not named individually but belongs to this class. Do not fly while taking it or until at least 5 times its maximum half-life has passed since your last dose. If you use it routinely, the AME must defer.

Pilot Tip

Always report all medications on your FAA medical application (Form 8500-8, Item 17a), even OTC medications. Failure to disclose is a far bigger issue than the medication itself.
