epidermal necrolysis) have been reported with the use of
carbamazepine. Frequently, the rash can involve ulcers of
the mouth, throat, nose, genitals and conjunctivitis (red and
swollen eyes). These serious skin rashes are often preceded
by influenza-like symptoms fever, headache, body ache
(flu-like symptoms). The rash may progress to widespread
blistering and peeling of the skin. The highest risk for
occurrence of serious skin reactions is within the first
months of treatment.
These serious skin reactions can be more common in people
from some Asian countries. The risk of these reactions in
patients of Han Chinese or Thai origin may be predicted by
testing a blood sample of these patients. Your doctor should
