Stribild Boxed Warnings
Post-treatment acute exacerbation of hepatitis B.
Test for HBV before starting antiretroviral therapy. Discontinuation of emtricitabine and/or tenofovir DF may be associated with severe acute exacerbations of hepatitis B. Closely monitor patients co-infected with HBV and HIV for several months after stopping treatment; if appropriate, anti-HBV therapy may be warranted (esp. in those with advanced liver disease or cirrhosis). New onset or worsening renal impairment. Assess SCr (monitor closely if >0.4mg/dL), estimated CrCl, urine glucose, urine protein in all patients, and serum phosphorus (in chronic kidney disease) before initiating and during therapy. Discontinue if significant renal dysfunction or evidence of Fanconi syndrome develops. Suspend therapy if lactic acidosis or hepatotoxicity (eg, hepatomegaly, steatosis) occurs. History of pathologic fracture or risk factors of osteoporosis or bone loss: consider bone mineral density (BMD) assessment; supplementation with calcium/Vit. D may be beneficial. Elderly. Pregnancy, nursing mothers: not recommended.
