Dolutegravir: what it treats, how to take it, side effects
Last updated September 3, 2026.
Dolutegravir is an HIV integrase inhibitor - it decreases the amount of HIV in the blood and lets the immune-cell count rebuild. You may know it as Tivicay. Not a cure - a daily hold, used with other HIV medications, that protects against AIDS and lowers transmission risk.
What does it treat?
HIV infection - in combination with other medications.
How do you take it?
Exactly as directed, same time daily - every day: with HIV treatment, adherence is the treatment. The supplement rule: antacids, calcium, iron, and multivitamins block its absorption - timing matters, and your doctor or pharmacist owns the spacing schedule. Never stop or run out without your doctor. Missed dose: take it as soon as you remember unless the next one is close; never double up.
Side effects to know
- Common: difficulty falling or staying asleep, headache, and tiredness.
- Serious - stop taking it and call your doctor immediately: the hypersensitivity set - rash, fever, excessive tiredness, muscle or joint pain, blistering or peeling skin, blisters or sores in the mouth, red or swollen eyes, swelling of the eyes, face, lips, mouth, tongue, or throat, difficulty breathing or swallowing; and the liver set - nausea, vomiting, loss of appetite, yellow eyes or skin, dark urine, pale bowel movements, pain in the upper right part of the stomach.
Who should not take it?
Flag liver disease including hepatitis B or C, kidney disease, and every other medication and supplement - the interaction list is long and real: certain seizure drugs, metformin, rifampin, and St. John's wort all collide. If you become pregnant, call your doctor.
When is it an emergency?
A rash with fever or facial swelling, trouble breathing, or yellowing eyes or skin is a 911 call. For an overdose, call Poison Control at 1-800-222-1222. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Why does my rash rule sound so strict?
Because on dolutegravir, a rash can be the first sign of a hypersensitivity reaction - and the company it keeps decides: rash plus fever, excessive tiredness, muscle or joint pain, blistering skin, mouth sores, red or swollen eyes, facial swelling, or trouble breathing is stop-the-drug, get-care-immediately. A lone mild rash still earns a same-day call. On this drug, rashes are reported, never watched.
Why did my pharmacist reschedule my vitamins?
Absorption: antacids, calcium, iron, and multivitamins bind dolutegravir and keep it out of the blood - a daily dose that never arrives. The fix is spacing: your doctor or pharmacist sets the hours between the supplement and the dose. It is the most common way this regimen quietly fails - and the easiest to prevent.
Why can't I ever just stop it?
HIV rebounds when the drug leaves - and gaps select for resistance, which can burn a regimen permanently. Never run out: refill before the bottle is empty, travel with extra, and any real stop or switch is planned with your doctor. The daily tablet is the hold; the hold is the point.
Why did my doctor ask about hepatitis?
The liver processes the drug, and hepatitis B or C changes the risk picture - the liver warning set is specific: nausea, vomiting, loss of appetite, yellow eyes or skin, dark urine, pale bowel movements, upper-right stomach pain. Those are call-immediately items. Baseline and periodic liver labs are how the watching works.
What about my other medications?
The interaction list is real: certain seizure drugs, rifampin, metformin, and St. John's wort collide with dolutegravir - doses move or drugs change. Every new prescription, OTC product, or supplement gets checked against it. One question at the pharmacy counter, every time, protects a regimen that cannot afford gaps.
What happens if I miss a dose of dolutegravir?
Take it as soon as you remember, unless it is almost time for the next one - then skip it and never double up. One late dose barely moves the week; a pattern of misses is how resistance gets selected. The same-time anchor - and a backup dose in your bag - keeps the streak alive.
