HIV medicines control the virus so your immune system can recover and you can live a normal life. Antiretroviral therapy (ART) lowers viral load to undetectable levels and dramatically cuts the risk of transmission. You don't need a medical degree to understand the basics - knowing what your drugs do and how to take them makes a big difference.
Most HIV drugs fall into a few clear classes. Nucleoside reverse transcriptase inhibitors (NRTIs) like tenofovir, emtricitabine and lamivudine form the backbone of many regimens. Non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs) are older options, while integrase strand transfer inhibitors (INSTIs) such as dolutegravir and bictegravir are now common first choices. There are also entry inhibitors for specific cases and boosters like ritonavir or cobicistat used to raise levels of other drugs. Many medications come as single-tablet combinations to simplify daily use.
Side effects vary by drug. Expect mild issues at first - nausea, headache, or sleep changes are common and often fade. Some drugs can affect kidneys or bone density, while others may cause weight changes or lipid shifts. Your clinician will check labs to spot problems early and switch medicines if needed. Don't hide side effects - small adjustments usually fix them.
Drug interactions matter. Antacids and calcium can reduce absorption of some INSTIs, certain statins don't mix well with boosted PIs, and tuberculosis meds like rifampicin require dose changes or different drugs. Always tell your provider about prescriptions, supplements, and herbal products. A quick pharmacy check can prevent major problems.
Sticking to your schedule prevents resistance. Missed doses give the virus a chance to adapt and limit future options. Many modern regimens are once daily and forgiving, but consistency still matters. If routine causes trouble, ask about long-acting injections or once-weekly approaches being developed - new options arrive fast.
Your care includes monitoring, not guessing. Viral load tests confirm suppression; CD4 counts track immune recovery. Expect viral load to drop within weeks and become undetectable in a few months if treatment works. Regular kidney, liver, and lipid tests help keep side effects in check.
Special situations need attention. Pregnant people on ART have very low transmission risk when treated properly. PrEP (preventive pills) and PEP (post-exposure pills) use some of the same drugs to prevent infection after exposure or before it happens. Talk to your provider right away if you think you need PEP.
Buy medications safely. Use licensed, reputable pharmacies and always fill prescriptions with a verified source. If you consider online options, confirm credentials and never skip a prescription requirement. When in doubt, ask your clinic or pharmacist for trusted suppliers.
Practical tips: use a pillbox or phone alarm, carry a list of your medicines, and bring copies of your prescriptions when you travel. Keep open communication with your care team and report new symptoms fast. With the right meds and habits, HIV becomes a manageable condition, not a life sentence.
