meds such as Mestinon may interfere with emg

I was on such a med for awhile. The name was Mestinon. But not for Myasthenia Gravis.

This is probably why some doctors and clinics ask you to put all your bottles of medication (heaven forbid, including over-the-counter and shudder, herbal or alternative concoctions) in a bag and bring them with you.

My opinion remains unchanged in regard to meds prior to emg/ncv- avoid all meds for a few hours.
