Tell your doctor immediately if you develop symptoms of liver disease, including persistent nausea/vomiting, severe stomach/abdominal pain, unusual weakness/tiredness, dark urine, yellowing eyes/skin.

Your doctor should order liver function tests while you are taking this medication. Keep all medical and laboratory appointments.
