Because your tongue is a muscle?

Are you allergic to it?

@tinyfaery I actually never thought of that lol
@Tink1113 Nope, not that I know of

Tongue numbness, or a paresthesia, is not due to the muscular nature of the tongue, but rather to a rare side effect of the medication. It may be instead that you are experiencing a dry mouth, which is a very common side effect. I’m not sure about the rarer condition, but the more common one is due to the anti-muscarinic receptor effects of the medication (Flexeril isn’t a classic tricyclic, but shares similar properties).

@shilolo It only happens when I break the pill. I thought it might have something to do with the actual medicine touching my tongue…?

Maybe you need to drink more water because ingesting pills takes up more water.

And if you don’t have anyother side effects, it’s not serious :)

here is a link saying dry mouth is a side effect.
