Overview
What is Dolutegravir?
Dolutegravir (DTG) is an integrase strand transfer inhibitor (INSTI) and one of the preferred first-line agents for HIV-1 treatment per WHO and US DHHS guidelines. It offers a high barrier to resistance, once-daily dosing, and is well tolerated. It is available in fixed-dose combinations including Triumeq (DTG/ABC/3TC) and Dovato (DTG/3TC).
Mechanism
How Does It Work?
1
Integrase binding
Dolutegravir binds directly to the integrase active site, chelating the two metal ions required for catalytic activity.
2
Strand transfer inhibition
By blocking the integrase active site, DTG prevents the viral DNA from integrating into the host cell's chromosomal DNA — a step essential for productive HIV infection.
3
High resistance barrier
DTG has a high barrier to resistance because it dissociates slowly from integrase. Resistance mutations that emerge under other INSTIs do not confer high-level resistance to DTG.
Dosage
How to Use
Timing
Once daily, at the same time each day (50mg standard dose)
How to Take
Take with or without food. Avoid taking within 2 hours of antacids, calcium, or iron supplements.
Frequency
Once daily (twice daily if resistance-associated integrase mutations or concurrent rifampicin use)
With Food
Food increases exposure slightly but is not clinically significant. High-calcium food/supplements — take DTG 2 hours before or 6 hours after.
Alcohol
No specific interaction, but alcohol can affect adherence
Missed Dose
Take as soon as remembered. If within 20 hours of next dose, skip the missed dose. Never double dose.

FAQ
Frequently Asked Questions
Why is Dolutegravir preferred for first-line HIV treatment?
Dolutegravir is recommended by the WHO and US DHHS as a preferred first-line agent because of its high barrier to resistance, once-daily dosing, good tolerability, and activity against HIV strains resistant to older drug classes.
Can I take Viropil Tablets with antacids or calcium supplements?
Antacids, calcium, iron, and magnesium supplements significantly reduce dolutegravir absorption. Take dolutegravir at least 2 hours before or 6 hours after taking these supplements.
Does Viropil Tablets affect mood or mental health?
Some patients report insomnia, depression, or mood changes. These neuropsychiatric effects are generally rare but should be reported to your doctor promptly. Taking dolutegravir with food or in the morning may reduce sleep disturbance.
Can women who are pregnant or planning pregnancy take Dolutegravir?
Yes. Dolutegravir is the preferred integrase inhibitor in pregnancy per WHO guidelines. Early concerns about neural tube defects have been addressed by larger studies showing the risk to be very low. Discuss with your HIV specialist.
Does Viropil Tablets cure HIV?
No. Dolutegravir suppresses viral replication to undetectable levels but does not eliminate HIV from the body. Consistent daily dosing is essential for ongoing viral suppression.
Drug Interactions
| Drug / Substance | Effect | Action |
|---|---|---|
| Rifampicin | Induces DTG metabolism — reduces exposure ~54% | Increase DTG dose to 50mg twice daily |
| Antacids / calcium / iron / magnesium | Divalent cations chelate DTG — reduce absorption significantly | Separate by ≥2 hours (before) or 6 hours (after) |
| Metformin | DTG inhibits OCT2/MATE1 — increases metformin exposure ~79% | Monitor blood glucose; reduce metformin dose if needed |
| Dofetilide | DTG inhibits OCT2 — significantly increases dofetilide — QT risk | Contraindicated |
Approved Indications
- HIV-1 infection in adults and children ≥4 weeks FDA / EMA (WHO-recommended)
