The Food and Drug
Administration last week approved one-day dosing of the
herpes treatment Famvir to treat recurrent genital herpes
and cold sores in people with healthy immune systems.
Previously, treating genital herpes required five days
of Famvir treatment at a lower dose. The drug was not
previously approved to treat cold sores, which also are
caused by a common herpes virus. Now treatment of
genital herpes can be completed with two
1,000-milligram doses of Famvir taken during just one day
immediately after the outbreak of herpes symptoms. Cold
sores are treated with a single 1,500-milligram dose.
The Centers for Disease Control and Prevention
estimates that about 45 million Americans over age 12 have
genital herpes, which is an incurable sexually transmitted
disease. (The Advocate)
