I'm pharmacist .. I found that some medications contain vitamin B complex which contain vitamin b3 / niacin taken by hepatic pt. Niacin is contraindicated in hepatic patient with active liver disease ... But I found that niacin less than 2 gm/day has no toxicity ... I get confused .. when they say that it's contraindicated means it's contraindicated absolutely or we should revise the max. dose ??
