Take care when using this medication as it can increase your risk of hepatitis. Drinking alcohol can increase this risk. You should have liver enzymes checked prior to starting the medication and monthly after starting. Report any symptoms of liver involvement like: unexplained anorexia/loss of appetite, nausea, vomiting, dark urine, rash, persistant fatique, weakness, fever lasting more than 3 days, and any upper right quadrant abdominal tenderness. These can be signs of liver problems. You should always take the medication on an empty stomach as taking it with food drastically decreases its absorption. Hope this helps!
