PEP (Post-Exposure Prophylaxis) regimens might differ based on the quantity of medications administered. Based on the quantity of medications used, the various PEP regimen types are broken down as follows:

2-Drug PEP Regimen

Usage: While this was formerly a popular regimen, more successful three-drug regimens have mostly supplanted it.

3-Drug PEP Regimen

Usage: Because it offers a better level of protection against HIV infection, this is the typical PEP regimen that is advised for the majority of people

4-Drug PEP Regimen

Usage: This regimen is typically reserved for treating HIV instead of PEP in cases when there is a substantial risk of drug resistance. For PEP, it is not commonly utilized. It can be administered with one additional drug from a different class and three NRTIs.

5-Drug PEP Regimen

Usage: For PEP, a five-drug regimen is quite uncommon and is often not employed. It may be taken into consideration in very particular situations when there is a high probability of HIV strains that are resistant to several medicines, or it may be used as a component of salvage therapy for people who have been diagnosed with HIV and have developed significant drug resistance.
