Hi..
Welcome to HEALTHCARE MAGIC..
As per your complain Mestinon that is used to treat
Myasthenia Gravis contains active ingredient
Pyridostigmine has a very rare incidence of causing toothloss..
While the real culprit can by Myasthenia Gravis itself as it can cause weakening of the muscles of the lower part of food pipe which stays contracted and prevent acid from coming to throat and mouth..
So the weakening of muscles caused by Myasthenia Gravis can cause frequent acid reflux and chemical erosion of teeth..
I would suggest you to
consult a Gastroenterologist and get evaluated and he can also advise an endoscopy..
For acid reflux Proton pump inhibitor like
Pantoprazole or Omeprazole, H2 blockers like Ranitidine and famotidine,antacids, light diet,
weight loss, taking more of Probiotics like Yoghurt in diet and sleeping with head slightly raised as compared to legs as well as reclining in left lateral position..
Hope this information helps..
Thanks and regards.
