For the Consumer

Applies to dolutegravir/lamivudine: oral tablet


Oral route (Tablet)

Warning: Patients Co-Infected with Hepatitis B Virus (HBV) and Human Immunodeficiency Virus (HIV-1): Emergence of Lamivudine-Resistant HBV and Exacerbations of HBVAll patients with HIV-1 should be tested for the presence of HBV prior to or when initiating dolutegravir / lamivudine. Emergence of lamivudine-resistant HBV variants associated with lamivudine-containing antiretroviral regimens has been reported. If dolutegravir / lamivudine is used in patients co-infected with HIV-1 and HBV, additional treatment should be considered for appropriate treatment of chronic HBV; otherwise, consider an alternative regimen. Severe acute exacerbations of HBV have been reported in patients who are co-infected with HIV-1 and HBV and have discontinued lamivudine, a component of dolutegravir / lamivudine. Closely monitor hepatic function in these patients and, if appropriate, initiate anti-HBV treatment.

Dolutegravir was shown to increase serum creatinine due to inhibition of tubular secretion of creatinine without affecting renal glomerular function. Increased serum creatinine was reported within the first 4 weeks of therapy and remained stable through 96 weeks. A mean change from baseline of 10.3 mcmol/L (range: -36.3 mcmol/L to 55.7 mcmol/L) was reported after 48 weeks of therapy with dolutegravir plus lamivudine; a mean change from baseline of 0.138 mg/dL was reported after 96 weeks of therapy with dolutegravir plus lamivudine. These changes were not considered clinically relevant.[Ref]

Frequency not reported: Renal impairment, increased serum creatinine (due to inhibition of tubular secretion of creatinine)[Ref]
