Possible Side Effects
Common: Malaise, fatigue, headache, abdominal discomfort, diarrhea. Rare/Severe: HBV viral flare on discontinuation, emergence of YMDD mutant resistant strains (up to 70% at 5 years), and lactic acidosis.
*Note: Individual physiological responses vary. While many patients experience few or no side effects, notify your treating physician if adverse reactions persist or if hypersensitivity (angioedema, skin rash, dyspnea) occurs.
Precautions & Warnings
Black Box Warning: Severe exacerbations of hepatitis B on treatment cessation. High rate of HBV resistance (YMDD mutation) compared to entecavir or tenofovir; modern guidelines prefer entecavir or TAF as first-line agents.
