A microbicide gel containing the HIV drug tenofovir (found in Atripla, Complera, Viread and Truvada) has been shown to be somewhat of a barrier to HIV. But it also offers the positive side effect of blocking herpes, too. In fact, while it reduces the chance of HIV transmission by 39 percent, it reduces the chance you’ll contract herpes by 51 percent.
It’s important to note that only the gel, not the pill form of tenofovir, produces this result.
The gel is not yet available, but given its harm reduction ability, we’re hoping it hits the streets soon.
