Missed PEP Dose

May 24, 2011

Dear Doc,

Two weeks ago I had protected (vaginal only) sex with a sex worker in Thailand. Was worried about possible HIV exposure and opted to take PEP.

Currently at two weeks into my treatment I feel asleep before taking my evening dose and and woke up with 4hrs to go for my next scheduled dose. I decided to wait and just take my next scheduled dose.

My question is whether this seriously compromises the treatment and if I should simply stop (although I don't appear to have any severe side effects).

Additionally, it just happens so that on the day that I missed the treatment I developed a mild sore throat - could this be ARS related? (no rash fever etc)

Thanks in advance.

Response from Dr. Frascino


PEP is not warranted for "protected sex." I'd encourage you to discontinue it.

If PEP were warranted, missing a single dose would not compromise your treatment. Your decision to wait the four hours until your next scheduled dose was correct. (You shouldn't take two doses within a short period of time.)
