After an exposure, I started taking PEP around 20 hours from the time of exposure. I was wondering how effective it would be on preventing an HIV infection, are there any studies done?
As well, I realized that I may have not taken it "correctly"? I was given two drugs, Truvada and Isentress, and I was instructed by the pharmacist to take 1 Truvada and 2 tablets of Isentress daily for 30 days. I usually took the one tablet of Isentress from around 8-9am, with the Truvada and Isentress combo from around 5-6pm. Was I supposed to exactly take them 12 hours apart? Will this reduce the effectiveness of the PEP treatment?
