Stevens-Johnson Syndrome is the bad rash everyone gets so concerned about with Lamictal. It considered an allergic reaction that can be gotten from virtually any drug, including Tylenol. It is extremely rare but potentially fatal if not treated. Serious conditions are treated in the burn unit. In many cases, flu-like symptoms precede the rash by a couple of days.
Lamictal also has a benign rash as an adverse reaction. While the chances of getting S-J is slightly higher with Lamictal, the overwhelming majority of rashes that occur will be the benign one. IIRC, 80% of the people who get the benign rash can restart Lamictal with no problems.
For whatever reason, the incidence of S-J is higher in antiepileptic drugs than most other classes of drugs and higher when more than one is taken. S-J rarely occurs after the first 8 weeks of taking the medication, usually much sooner.
And, it seems, every rash anyone gets while taking the drug is blamed on the drug.
ETA: S-J is not usually fatal.
