Hi thanks for asking question. Almost every drug in excess can affect liver. The only disease modifying drug or other necessary drug should be taken for rheumatoid arthritis with follow up monthly. You have fatty liver also.So because of that also liver enzymes could be high. Take more fruits and green leafy vegetables. Avoid fatty food in excess. In cooking use very less oil. Avoid bad fat that is butter, cheese, cookies ,chicken , pork meat avoided. Refined food avoided. If possible mild exercise good for you. Crushed garlic can be taken daily that is good herbal remedy ... Take care.... Dr.Parth
