Antiretroviral Therapy (ART) Explained
How HIV treatment works and what to expect in Nigeria
Antiretroviral therapy (ART) is a combination of medicines that suppress HIV replication, protect the immune system, and prevent disease progression. Since the introduction of modern ART, HIV has transformed from a death sentence into a manageable chronic condition. People who start ART early, take it consistently, and achieve an undetectable viral load live as long as HIV-negative people. In Nigeria, over 1.5 million people are on ART — mostly receiving it free through government and PEPFAR-supported treatment sites. This guide explains how ART works, common regimens in Nigeria, side effects, and what 'success' looks like.
Signs and Symptoms
✓ ART itself has no 'symptoms of working' — effect is measured through viral load tests
✓ Goal: viral load undetectable (< 50 copies/mL) within 3–6 months of starting
✓ Goal: CD4 count rising towards normal (> 500 cells/µL)
✓ Immune reconstitution inflammatory syndrome (IRIS): some infections may temporarily flare as immune system recovers — expected, manageable
✓ Common early side effects (usually settle within 4–8 weeks): nausea, fatigue, headache
✓ Dolutegravir-based regimens (standard in Nigeria 2024): excellent tolerability
When to Seek Help
Starting ARTAll people diagnosed with HIV should start ART on the day of diagnosis or within 7 days — regardless of CD4 count. 'Test and treat' is Nigeria's national policy
Signs of treatment failureIf viral load remains detectable after 6 months on ART despite reported adherence — drug resistance testing and regimen switch needed
Severe side effectsJaundice (yellow eyes/skin), severe rash with blistering, confusion, muscle weakness — some rare but serious ARV reactions need prompt medical review
Starting TB treatmentRifampicin interacts with many ARVs — dose adjustment or drug switch needed. TB and HIV together require specialist management
Pregnancy while on ARTContinue ART — do not stop. Regimen review needed for pregnancy safety (dolutegravir now considered safe in pregnancy)
Tests & Diagnosis
🧪 Viral load
At ART start, then 3 months, 6 months, then every 6–12 months. Target: < 50 copies/mL (undetectable). Nigeria now offers viral load monitoring at most treatment sites
🧪 CD4 count
At diagnosis and periodically — less important once viral load is suppressed but still used to guide prophylaxis decisions
🧪 Full blood count
Monitors for anaemia (especially with zidovudine-containing regimens, now rarely used)
🧪 Liver function tests
At baseline and if symptoms — some ARVs are metabolised by liver; hepatitis B co-infection common in Nigeria
🧪 Kidney function (creatinine)
Tenofovir (TDF) can occasionally affect kidneys — monitored annually
🧪 Fasting lipid profile
Some ARVs raise cholesterol — annual monitoring recommended
Frequently Asked Questions
Do I have to take ARVs for life?
With current technology, yes — ART controls HIV but does not eliminate it from the body. Stopping ART allows the virus to rebound rapidly. Research into long-acting injectable ART (given monthly or every 2 months) is advancing and may become available in Nigeria in coming years.
Can I drink alcohol on ART?
Moderate alcohol does not directly inactivate ARVs, but heavy alcohol severely reduces adherence and increases liver damage risk. Many people on ART choose to avoid alcohol entirely.
Will people know I'm HIV positive from my medicines?
ARV pills look like any other tablet and their packaging is plain at most Nigerian clinics. However, if discretion is important, discuss with your clinic — some offer multi-month dispensing (3–6 months of pills at once) to reduce clinic visits and the need to pick up monthly.
What is U=U?
Undetectable = Untransmittable. If your viral load is maintained below 50 copies/mL for at least 6 months, you CANNOT transmit HIV sexually — not just reduced risk, zero risk. This is one of the most important advances in HIV science.
