Can a "lamictal rash" manifest in the groin?

Possible: A drug rash can manifest anywhere, but it is unlikely for Lamictal to be solely isolated to the groin.

Lamictal: Check with your physician immediately. Rash from Lamictal (lamotrigine) can appear anywhere in the body (groin, back, arms, torso). This could be more serious than just a simple drug allergy (steven johnson syndrome). Check with your physician to evaluate if substitution with a different medication is necessary.
