Hello and welcome - Liver issues are not common, but this *is* an issue to be aware of, expecially since methimazole has a better track record than does PTU.
The good news is that of those who do experience liver issues, the vast majority recover quickly once the issue is identified and the meds are stopped. Potential signs & symptoms of liver issues can include fever, loss of appetite, nausea, vomiting, tiredness, itchiness, dark colored urine, or yellowing of the skin or eyes - so if you experience any of these call your doctor's office ASAP for further guidance.
