David L. Kaplan, MD—Series Editor

    Note: 166,330 people have reported side effects to FDA from Enbrel, 106 have post-herpetic neuralgia since 2005, 57% have been on Enbrel less than six months, and 95% had been on Enbrel less than two years. This data would suggest that individuals over the age of 50 on etanercept in the first years should be monitored for herpes zoster; however, the risk for post-herpetic neuralgia is uncertain as it is unknown if the incidence noted above is any greater than would expected. ■
