Anyone familiar with pilocarpine?

So I have sjogrens, it typically effects eyes and mouth dryness.... I just turned 30 and I swear it’s like I turned 30 and the next day I’ve started having some crucial va jay jay dryness 😩😩 I’m prescribed pilocarpine for sjogrens... I’m wondering if it would help with the vaginal dryness?! I just hate taking it cause I sweat so much!
