Most people who are allergic to sulfa based medicationss are also allergic to Lamictal. The reactions vary from blisters in the mouth to busted eyeball capillaries, to a very serious SJS or TENS reaction.
Pain in the ankles and the joints feeling like glass is inside of them are also symptoms, and the sufferer is often prescribed other medications for conditions which simply do not exist.
If you take Lamictal, be on the lookout as the side effects are as violent as the bi-polar condition itself.
Most people start to show signs of side effects within 10 days of the dosage.
