Monthly Dapivirine Ring (IMAGE) International Partnership for Microbicides (IPM) Caption IPM's dapivirine vaginal ring could help fill an important gap with a long-acting product that a woman controls and could use discreetly to reduce her HIV risk during vaginal sex. The ring slowly releases the antiretroviral (ARV) drug dapivirine over the course of a month to reduce a woman's HIV risk. Women insert the product and replace it every month.
