|Dolutegravir (DTG, Tivicay)
Tablets: 10 mg, 25 mg, 50 mg
Fixed-Dose Combination Tablets:
When using fixed-dose combination (FDC) tablets, refer to other sections of the Drug Appendix for information about the individual components of the FDC. See also Appendix A, Table 2.

||Selected Adverse Events
|Neonate and Infant Dose:
Child (Weighing <20 kg) Dose:
- Dolutegravir (DTG) is not approved for use in neonates or infants.
Child and Adolescent (Weighing ≥20 kg to <40 kg) Dose:
- No dosing recommendations can be made for children weighing <20 kg.
- The Panel on Antiretroviral Therapy and Medical Management of Children Living with HIV (the Panel) recommends using an investigational dose of DTG 50 mg once daily for children and adolescents weighing ≥20 kg who are antiretroviral therapy (ART)-naive or ART-experienced (but integrase strand transfer inhibitor [INSTI]-naive) and who are not being treated with uridine diphosphate glucuronyl transferase (UGT) 1A1 or cytochrome P450 (CYP) 3A inducers or inhibitors.
- DTG is not approved by the Food and Drug Administration (FDA) for use in children weighing <30 kg. However, interim data from ongoing trials indicate that using the FDA-approved dose of DTG 35 mg in patients weighing ≥30 kg to 40 kg may result in suboptimal trough concentrations, and additional data supports the 50-mg dose recommended by the Panel (see text). Using a 50-mg dose also avoids the need to administer two tablets with different strengths (i.e., a 10-mg tablet plus a 25-mg tablet).
Child and Adolescent (Weighing ≥40 kg) and Adult Dose
|ARV-naive or ARV-experienced/INSTI-naive patients
||DTG 50 mg once daily
|ARV-naive or ARV-experienced/INSTI-naive patients who are also receiving one of the following potent UGT1A/CYP3A inducers: efavirenz, fosamprenavir/ritonavir, tipranavir/ritonavir, or rifampin
||DTG 50 mg twice dailya
|INSTI-experienced patients with any INSTI-associated resistance mutations or clinically suspected INSTI resistance
||DTG 50 mg twice dailya,b
|a The 50-mg, twice-daily dose should not be used in patients weighing <40 kg.
b These patients should receive drug combinations that do not include metabolic inducers when possible.
- One tablet once daily with or without food as a complete regimen in ARV-naive adults with no known mutations associated with resistance to the individual components of Dovato.
- Dovato is not approved by the FDA or recommended by the Panel for use in children or adolescents as a complete regimen. However, it could be used as part of a three-drug regimen in patients who meet the minimum body weight requirements for each component drug (see the Simplification of Treatment section below).
- One tablet once daily with a meal as a complete regimen to replace the current ARV regimen in patients who have been virologically suppressed (HIV RNA <50 copies/mL) on a stable ARV regimen for at least 6 months with no history of treatment failure and no known mutations associated with resistance to the individual components of Juluca.
- Juluca is not approved by the FDA or recommended by the Panel for use in children or adolescents as a complete regimen (see the Simplification of Treatment section below).
Child and Adolescent (Weighing ≥25 kg) and Adult Dose:
- One tablet once daily with or without food.
- For use in patients who are ARV-naive or ARV-experienced (but INSTI-naive) and who are not being treated with UGT1A1 or CYP3A inducers.
- See the Abacavir section for special instructions about testing for abacavir hypersensitivity.
- The FDA-approved dose for pediatric patients weighing ≥40 kg is one tablet once daily.
- Neuropsychiatric symptoms (i.e., depression and/or suicidal thoughts or actions), especially in patients with a history of psychiatric illness
- Rare cases of hypersensitivity reactions, including rash and drug reaction (or rash) with eosinophilia and systemic symptoms, constitutional symptoms, and organ dysfunction (including liver injury) have been reported.
- DTG may be taken without regard to meals.
- DTG should be taken 2 hours before or 6 hours after taking cation-containing antacids or laxatives, sucralfate, oral iron supplements, oral calcium supplements, or buffered medications.
- In patients who have difficulty swallowing tablets whole, 10-mg, 25-mg, and 50-mg tablets may be either split into halves followed by immediate ingestion of both halves of the tablet, or crushed and added to a small amount of semisolid food or liquid, all of which should be consumed immediately.1
- The efficacy of DTG 50 mg twice daily is reduced in patients with certain combinations of INSTI-resistance mutations (see the Resistance section below).
- Patients should be tested for hepatitis B virus (HBV) infection prior to use of Triumeq or Dovato. Lamivudine (3TC)-resistant HBV variants have been reported in patients who received 3TC-containing ARV regimens. Patients with HBV/HIV coinfection who receive Dovato will require additional treatment for chronic HBV infection. Severe exacerbation of hepatitis can occur in patients with HBV/HIV coinfection who discontinue 3TC.
Dolutegravir Dosing in Patients with Hepatic Impairment:
- UGT1A1 and CYP3A substrate. Drugs that induce these enzymes and transporters may decrease plasma concentrations of DTG. Drugs that inhibit these enzymes may increase DTG plasma concentrations.
Dolutegravir Dosing in Patients with Renal Impairment:
- No dose adjustment is necessary in patients with mild or moderate hepatic impairment. Due to a lack of data, DTG is not recommended for use in patients with severe hepatic impairment.
- DTG decreases tubular secretion of creatinine and increases measured serum creatinine, without affecting glomerular filtration.
- No dose adjustment is required in INSTI-naive patients with mild, moderate, or severe renal impairment, or in INSTI-experienced patients with mild or moderate renal impairment.
- Use DTG with caution in INSTI-experienced patients with severe renal impairment (creatinine clearance <30 mL/min), because DTG concentrations will be decreased. The cause of this decrease is unknown.
