title: Nevirapine (Viramune) strengthens warning on liver, skin toxicities.
abstract: A recent letter to doctors strengthened the U.S. warnings and precautions on using this antiretroviral (which has been approved and in widespread use for years), due to serious complications in a small minority of patients; the point of the changes is to catch such problems and stop the drug in time. Patients obtaining refills or new prescriptions should in the future receive a "patient package insert," dated November 2000, based on the new warnings.
