If you have cirrhosis you should be under the care of a liver specialist to answer any questions about any medication you are taking. Yes taking iron supplements can dangerous for those with advanced liver disease.
If you do not have F3 fibrosis or F4 cirrhosis then you should ask this of your treating physician.
However, as a layperson who has hep c and now living with cirrhosis as long as you do not have cirrhosis or agvanced liver damage it should not be an issue. But again I am not a medical person of any kind just a patient for an informed and accurate answer ask a medical professional.
