I was recently exposed to HSV-2, close contact but no intercourse. I recently lost 3 family members and the stress of contracting herpes might put me over the edge. I realize this has probably made me overly paranoid about contracting the virus, however, I'm considering post-exposure prophylaxis with Famciclovir. Is there any reason not to proceed (beyond the fact that it is considered "off-label" and not proven to suppress the virus)?
