The median time to rash that resulted in discontinuation was 13 days. No such cases were observed among pediatric patients who received placebo. The reporting rate of TEN and SJS associated with modafinil use, which is generally accepted to be an underestimate due to underreporting, exceeds the background incidence rate.
Estimates of the background incidence rate for these serious skin reactions in the general population range between 1 to 2 cases per million-person years. Nearly all cases of serious rash associated with modafinil occurred within 1 to 5 weeks after treatment initiation. However, isolated cases have been reported after prolonged treatment e. Accordingly, duration of therapy cannot be relied upon as a means to predict the potential How Should I Take Provigil heralded by the first appearance of a rash.
