Shar, NEVER use mosquito repellant again!!!! Did you know that catnip works just as well?

Those pesticides, and it is a pesticide, acts like Mestinon on steroids. It inhibits acetylcholinesterase and increases acetylcholine. That's not a good thing if you are on Mestinon because you could have a cholinergic crisis. The other thing pesticides do is to irreversibly destroy the neuromuscular junction!!!

You absolutely should go seek out help. At the very least, call your neuro. If you still feel like you can't breathe in, go to the ER right away. Do not hesitate in doing so!!! They need to check your arterial blood gases as well as O2 stats and breathing tests. Tell them that you exposed yourself to pesticides and got worse afterwards.

Mestinon kicks in about 20-30 minutes after taking it. It will wear off about 2-1/2 hours after taking it. So you get about 2 good hours of it. If you are weaker off of Mestinon, then it is making you better by taking it. If you are weaker on it, the opposite is true. Make sense?

This is nothing to mess with. You need to seek out help. And stay away from the pesticides; they are not safe for people with MG (or anyone else in my opinion).

I hope you will feel better soon.
