1 tab once daily with food. Renal impairment (CrCl <70mL/min): not recommended; if CrCl declines to <50mL/min during therapy, discontinue. Severe hepatic impairment: not recommended.

Suspend therapy if lactic acidosis or hepatotoxicity (eg, hepatomegaly, steatosis) occurs. Not for treating chronic hepatitis B; test for HBV before starting therapy and closely monitor patients co-infected with HBV and HIV during and for several months after stopping treatment (discontinuing therapy may exacerbate HBV infection). Monitor CrCl, urine glucose, urine protein, serum phosphorus (for patients at risk for renal impairment). History of pathologic fracture or risk factors of osteoporosis or bone loss: consider monitoring bone mineral density (BMD). Elderly. Pregnancy (Cat.B). Nursing mothers: not recommended.
