Hello I'm a 30 year old heterosexual circumcised male and recently had brief unprotected vaginal intercourse with a CSW in Thailand, no oral sex occurred, I was under the influence of alcohol.
The CSW was early 20s and told me there was nothing to worry but her status is unknown. Neither of us demonstrated any visible STI or wounds at the time of exposure.
Within 36 hours i went to a commercial walk in clinic and was given a 1g intramuscular injection of ceftriaxone and a 28 perscription of PEP 1 pill (tenofovir, emtricitabine, dolutegravier). After reading more and more it seems like the PEP might be overkill in my situation, and the clinic seemed eager to keep adding things to my bill, more shots, more prescriptions, so i'm looking for an alternative. I did a baseline test and was completely clean, good liver and kidney function, but no hep B vaccine.
In this scenario is PEP advisable? Aside from a persistent headache, i haven't had my other sides but i'm concerned about the medication and don't know enough about any potential long term effects regarding that combination. I'm on no other medication.
Finally midway through the PEP (if i complete the treatment) i'll be traveling to a time zone 12 hours behind Thailand, is it advisable to adjust the medication schedule so it stays consistent (e.g. if I've been taking it at noon , switch to midnight?)
Thanks for any insights and help here. Obviously i'll get tested at the appropriate times.
