Boxed warnings

• WARNING: HYPERSENSITIVITY REACTIONS, AND EXACERBATIONS OF HEPATITIS B Hypersensitivity Reactions Serious and sometimes fatal hypersensitivity reactions, with multiple organ involvement, have occurred with abacavir, a component of TRIUMEQ and TRIUMEQ PD (abacavir, dolutegravir, and lamivudine). Patients who carry the HLA ‑ B*5701 allele are at a higher risk of a hypersensitivity reaction to abacavir, although hypersensitivity reactions have occurred in patients who do not carry the HLA ‑ B*5701 allele [see Warnings and Precautions ( 5.1 )] . TRIUMEQ and TRIUMEQ PD are contraindicated in patients with a prior hypersensitivity reaction to abacavir and in HLA ‑ B*5701-positive patients [see Contraindications ( 4 ), Warnings and Precautions ( 5.1 )] . All patients should be screened for the HLA ‑ B*5701 allele prior to initiating therapy with TRIUMEQ or TRIUMEQ PD or reinitiation of therapy with TRIUMEQ or TRIUMEQ PD, unless patients have a previously documented HLA ‑ B*5701 allele assessment. Discontinue TRIUMEQ or TRIUMEQ PD immediately if a hypersensitivity reaction is suspected, regardless of HLA ‑ B*5701 status and even when other diagnoses are possible [see Contraindications ( 4 ), Warnings and Precautions ( 5.1 )] . Following a hypersensitivity reaction to TRIUMEQ or TRIUMEQ PD, NEVER restart TRIUMEQ or TRIUMEQ PD or any other abacavir ‑ containing product because more severe symptoms, including death can occur within hours. Similar severe reactions have also occurred rarely following the reintroduction of abacavir-containing products in patients who have no history of abacavir hypersensitivity [see Warnings and Precautions ( 5.1 )] . Exacerbations of Hepatitis B All patients with HIV-1 should be tested for the presence of hepatitis B virus (HBV) prior to or when initiating TRIUMEQ or TRIUMEQ PD. Emergence of lamivudine-resistant HBV variants associated with lamivudine-containing antiretroviral regimens has been reported. If TRIUMEQ or TRIUMEQ PD 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 hepatitis B have been reported in patients who are co ‑ infected with HBV and HIV-1 and have discontinued lamivudine, a component of TRIUMEQ and TRIUMEQ PD. Closely monitor hepatic function in these patients and, if appropriate, initiate anti-HBV treatment [see Warnings and Precautions ( 5.2 )]. WARNING: HYPERSENSITIVITY REACTIONS, AND EXACERBATIONS OF HEPATITIS B See full prescribing information for complete boxed warning. Hypersensitivity Reactions • Serious and sometimes fatal hypersensitivity reactions have occurred with abacavir-containing products. ( 5.1 ) • Hypersensitivity to abacavir is a multi-organ clinical syndrome. ( 5.1 ) • Patients who carry the HLA ‑ B*5701 allele are at a higher risk of experiencing a hypersensitivity reaction to abacavir. ( 5.1 ) • TRIUMEQ and TRIUMEQ PD are contraindicated in patients with a prior hypersensitivity reaction to abacavir and in HLA-B*5701-positive patients. ( 4 ) • Discontinue TRIUMEQ or TRIUMEQ PD as soon as a hypersensitivity reaction is suspected. Regardless of HLA-B*5701 status, permanently discontinue TRIUMEQ or TRIUMEQ PD if hypersensitivity cannot be ruled out, even when other diagnoses are possible. ( 5.1 ) • Following a hypersensitivity reaction to TRIUMEQ or TRIUMEQ PD, NEVER restart TRIUMEQ, TRIUMEQ PD, or any other abacavir ‑ containing product. ( 5.1 ) Exacerbations of Hepatitis B • All patients with HIV-1 should be tested for the presence of hepatitis B virus (HBV) prior to or when initiating TRIUMEQ or TRIUMEQ PD. Emergence of lamivudine-resistant HBV variants associated with lamivudine-containing antiretroviral regimens has been reported. If TRIUMEQ or TRIUMEQ PD 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 HBV and HIV ‑ 1 and have discontinued lamivudine, a component of TRIUMEQ and TRIUMEQ PD. Closely monitor hepatic function in these patients and, if appropriate, initiate anti-HBV treatment. ( 5.2 )
