Explain Adverse effects of Emtricitabine
Emtricitabine can cause hyperpigmentation of the palms and soles, particularly in dark-skinned patients. Because emtricitabine is also active against hepatitis B virus (HBV), HIV-positive patients with chronic HBV infection may experience a flare of hepatitis if emtricitabine is withdrawn or if their HBV strain becomes resistant to the drug.
