The sections below are summarized in plain English from dolutegravir's FDA-approved prescribing information. They describe what the official label says, and are not personal medical advice.
How It Works
TRIUMEQ contains three drugs that each work differently to stop HIV from multiplying. Dolutegravir is an integrase strand transfer inhibitor (INSTI). Abacavir and lamivudine are nucleoside analogue reverse transcriptase inhibitors.
How to Take It
Take one TRIUMEQ tablet every day. You can take it with or without food. For children weighing 6 kg to less than 25 kg, use TRIUMEQ PD tablets for oral suspension as directed by your doctor. Do not substitute TRIUMEQ tablets and TRIUMEQ PD tablets for oral suspension on a milligram-per-milligram basis.

Serious Warnings
TRIUMEQ can cause serious allergic reactions. If you have a gene called HLA-B*5701, you are more likely to have an allergic reaction. You should be tested for this gene before taking TRIUMEQ. Symptoms can include fever, rash, nausea, vomiting, diarrhea, or stomach pain. Some people can also experience liver problems or a heart attack.
Known Drug Interactions
Dolutegravir may increase plasma concentrations of drugs eliminated via OCT2 or MATE1 (dofetilide, dalfampridine, and metformin) [see Contraindications ( 4 ), Drug Interactions ( 7.3 )] . Other Agents Antiarrhythmic: Dofetilide ↑Dofetilide Coadministration is contraindicated with TRIUMEQ and TRIUMEQ PD [see Contraindications ( 4 )] .
Mechanism: Dolutegravir blocks the proteins in the kidneys that normally help remove dofetilide from the body. This causes the levels of dofetilide in your blood to rise.
What to do: Do not take these two medications together. Your doctor will need to find an alternative treatment.
Drugs that Reduce Metformin Clearance Clinical Impact Concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) could increase systemic exposure to metformin and may increase the risk for lactic acidosis [see Clinical Pharmacology (12.3) ] .
Mechanism: Dolutegravir blocks the kidneys from removing metformin from the body. This can cause metformin levels to rise, which increases the risk of a serious condition called lactic acidosis.
What to do: Your doctor may need to adjust your dose or monitor you more closely for side effects.
Drugs that Reduce Metformin Clearance Clinical Impact Concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) could increase systemic exposure to metformin and may increase the risk for lactic acidosis [see Clinical Pharmacology (12.3) ] .
Mechanism: Dolutegravir blocks the kidneys from filtering metformin out of your blood, which makes metformin levels rise. Higher levels of metformin increase the risk of a serious health problem called lactic acidosis.
What to do: Your doctor may need to lower your metformin dose or check your blood levels more often.
Drugs that Reduce Metformin Clearance Clinical Impact: The risk of lactic acidosis may increase due to concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) which increase systemic exposure to metformin Intervention Consider the benefits and risks of concomitant use.
Mechanism: Dolutegravir blocks the kidneys from removing metformin from the body, which causes metformin levels to rise and increases the risk of side effects.
What to do: Your doctor should carefully consider the risks and benefits of using these two medications at the same time.
Drugs that Reduce Metformin Clearance Clinical Impact Concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) could increase systemic exposure to metformin and may increase the risk for lactic acidosis [see Clinical Pharmacology (12.3) ] .
Mechanism: Dolutegravir prevents your kidneys from removing metformin from your body. This can cause the drug to build up and increase the risk of a serious condition called lactic acidosis.
What to do: Your doctor may need to adjust your dose or monitor you more closely. Tell your doctor if you feel very weak, dizzy, or have trouble breathing.

The FDA label for dolutegravir (sold under brand names such as Tivicay) classifies it as a prescription-only medication in the Integrase Strand Transfer Inhibitor class. TRIUMEQ treats HIV-1, the virus that causes AIDS. Official labeling lists 3 commonly reported side effects, including Trouble sleeping (insomnia), Headache, Feeling tired.
Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 8,756 voluntary reports. The database also lists 28 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated major severity. NADAC pricing from CMS.
Report counts do not establish causation, a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information further shape supply and switching decisions.
