Today, people on HIV medication can suppress the virus to undetectable levels and prevent transmission. That’s the most powerful reason to learn how these drugs work and how to take them right. This page gives straight, useful info on HIV meds and points you to deeper reads, like our piece on atazanavir.
Antiretroviral therapy (ART) mixes drugs that block HIV at different steps. Common classes you’ll hear about are:
- NRTIs (nucleoside reverse transcriptase inhibitors): stop the virus from copying its genetic material.
- NNRTIs (non-nucleoside RT inhibitors): also block copying but in a different spot.
- PIs (protease inhibitors): prevent the virus from maturing into infectious particles—atazanavir is a protease inhibitor you can read about in our Atazanavir article.
- INSTIs (integrase strand transfer inhibitors): stop the virus from inserting its DNA into your cells.
- Entry and fusion inhibitors: block HIV from getting into cells in the first place.
Most modern regimens combine drugs from different classes so the virus has a harder time becoming resistant.
Take them every day. Missed doses give the virus a chance to rebound or become resistant. Set alarms, use a pill box, or sync with a daily habit (morning coffee, brushing teeth).
Side effects vary. Some people have mild nausea or headaches at the start. Others notice changes in sleep, weight, or cholesterol. If something feels wrong, talk to your provider — many side effects can be managed or the drug can be switched.
Watch interactions. HIV meds interact with common medications and supplements. For example, some protease inhibitors need an acidic stomach to work and clash with antacids or proton pump inhibitors. Always tell the clinician what else you take.
Labs matter. Regular blood tests monitor viral load, CD4 count, liver and kidney function. These tests tell your health team if the regimen is working or needs change.
Thinking about buying meds online? Be careful. Use accredited pharmacies, require a prescription, and look for clear contact info and secure checkout. We review online pharmacy options and safety tips on the site if you want guidance.
If you haven’t started treatment, ask about modern single-tablet regimens and about PrEP if you’re HIV-negative and at risk. If you’re already on meds, keep appointments, report side effects, and never stop treatment without medical advice.
