TUESDAY, March 17, 2015 – A widely used herpes drug also seems to help people with the HIV virus, even if those people don't also have herpes, a new small study found. The researchers said their findings challenge the belief that drug Valtrex (valacyclovir) requires the presence of herpes to benefit people with HIV-1. HIV is the virus that causes AIDS. The study included 18 HIV patients in Peru. When patients took Valtrex twice daily for two weeks, they had decreases in HIV-1 levels. Patients taking a placebo saw their HIV levels go up. Experts thought that Valtrex worked against HIV by reducing inflammation caused by the herpes virus. This would give the HIV virus fewer active immune cells to attack, reducing the spread of the virus. But the drug doesn't depend on reducing inflammation to work against HIV, said study co-senior author Dr. Michael Lederman, a professor of medicine at ... Read more

And while the use during pregnancy of antiviral drugs such as acyclovir (Zovirax), valacyclovir (Valtrex) and famciclovir (Famvir) are believed to be safe, data on their use in early pregnancy has been limited, the researchers noted. But the new analysis suggests that "pregnant women needing treatment for a herpes infection in the first trimester can use antivirals without concern about birth defect risk," said lead researcher Dr. Bjorn Pasternak, from the department of epidemiology research at the Statens Serum Institut in Copenhagen. Acyclovir was the most commonly used antiviral, and should be the antiviral drug of choice in ... Read more
