I've been on Pilocarpine for about a year or more.
I started on Salagen about 8 years ago, then switched to Evoxac somewhere along the way.
I switched to Pilocarpine cause it is slightly cheaper and I end up in the donut hole in Medicare so it matters.
It works fine for me. Mostly for saliva, in fact it is almost over producing saliva in the mornings, if anything, when I take two.
I take two at night. I still take a bit of water when I wake up, and spray my eyes and pee cause I have Interstitial Cystitis. But I don't get horribly dry.
I also make sure my nose is clear, cause if I have to BREATHE through my mouth, nothing helps enough.
Keep us posted.
