Generic Medicine Info
Contraindications
Lactation. Not to be used for treatment of chronic hepatitis B virus (HBV) infection.
Special Precautions
Liver impairment. Renal impairment; avoid in CrCl <30ml/min and in patients on dialysis. Pregnancy. Not to be used with other emtricitabine, tenofovir disoproxil fumarate or other cytidine analogues (e.g. lamivudine and zalcitabine) preparations. Avoid use in antiretroviral-experienced patients with K65R mutation; in treatment experienced patients, use of combination drug to be guided by laboratory testing and treatment history. Increased risk for severe and potentially fatal hepatic adverse reactions in patients with HIV and hepatitis B or C virus co-infection treated with antiretroviral agents. If combination drug is discontinued in patients co-infected with HIV and HBV, monitor hepatic function for several months for acute exacerbation of hepatitis. Discontinue therapy if there is a rapid rise in aminotransferase concentrations, progressive hepatomegaly or steatosis, metabolic or lactic acidosis of unknown cause. Test for presence of chronic HBV before initiating therapy. Check CrCl before initiation of therapy and monitor renal function (CrCl and serum phosphate) every 4 wkly during the 1st year and then every 3 mthly (more frequently in patients at risk for renal impairment). Bone monitoring needed for patient with history of pathologic bone fracture or at risk of osteopenia. Monitor child exposed in utero to combination drug for possible mitochondrial dysfunction.
