relatively new and is based on dexamethorphan (plus other ingredients) which is used in cough medicine containing DM. Since it could make my MG worse, we decided to start with the cough medicine and see what happens. If the cough medicine does not bother my Myasthenia Gravis, then on to the prescription medicine.
By Friday, I was taking the full dose--and my MG hit with a vengeance. Thirty minutes after taking the cough medicine my breathing worsened so much that I needed to use my bi-pap machine. Thirty minutes after that, my vision became very blurry and my eyes hurt. A few hours later my voice became really distorted and sounded like it did in my YouTube video (http://www.youtube.com/user/drbunn?feature=mhum#p/u/6/N4qK_O4Eyc4). I have not taken any more medication.
