Any rash — even a mild one — appearing in the first 8 weeks must be taken seriously. It may be an early warning sign of Stevens-Johnson Syndrome (SJS) which is potentially fatal. Stop the medicine immediately and see a doctor.

SJS kya hota hai?

Stevens-Johnson Syndrome (SJS) is a rare and potentially fatal skin reaction in which the skin blisters and peels — like a burn injury. Severe sores in the mouth, fever, and eye problems can also occur. With Lamictal this mainly occurs with rapid dose escalation — which is why slow titration is essential.
