HIV treatment begins after confirmed diagnosis with ART. PEP is emergency prevention for a person not diagnosed with HIV after a possible exposure. These are different clinical situations and must be separated.
After HIV Is Confirmed
Prompt linkage and ART are recommended. Assessment includes viral load, CD4, hepatitis, kidney and liver health, STIs, and symptoms of opportunistic infection. Initial therapy often combines several medicines in one tablet but must reflect health and interactions.
ART and U=U
ART suppresses HIV, supports immune recovery, and prevents progression. Sustained viral load below 200 copies/mL prevents sexual transmission. Suppression is not cure, so treatment should not be stopped independently.
PEP Is Not HIV Treatment
PEP is for a possible exposure in someone without diagnosed HIV. It must begin as soon as possible and no later than 72 hours and is generally taken for 28 days. If HIV is found, the provider arranges a complete ART regimen instead.
Long-Term Care
Complete viral-load monitoring and address vaccination, mental health, chronic conditions, and sexual health. Discuss side effects or missed doses rather than buying or changing medicine independently.
