MrsD, I was prescibed prostigmin here in Iowa on August 2 of this year. Now as it is not used as commonly it is not as easy to find info on and spelling it correctly was part of my struggle. It took quite a time to dig up info on it. I keep putting an 'e' at the end. Valeant makes it and I just talked to them this week on their customer service line about my problems with both mestinon and prostigmin which they both make.
