Name the drugs, doses and duration of treatment after post-exposure prophylaxis of HIV.
Post-Exposure Prophylaxis (PEP) for HIV:
PEP should start as soon as possible, ideally within 2 hours and no later than 72 hours after exposure. The standard regimen includes three antiretroviral drugs for 28 days. Two NRTIs: Tenofovir disoproxil fumarate (TDF) + Emtricitabine (FTC) or Tenofovir alafenamide (TAF) + FTC. One INSTI: Dolutegravir (50 mg once daily), Raltegravir (400 mg twice daily), or Bictegravir (as fixed-dose). TDF/FTC dose: 300/200 mg once daily; TAF/FTC: 25/200 mg once daily. Strict adherence is crucial, and follow-up HIV testing is recommended after completion to ensure efficacy.
