Houston Podiatrist and Foot Surgeon Dr. Andrew Schneider discusses whether oral medication used to treat toenail fungus causes liver problems. This is a very common question that I receive in my Houston podiatry office. Years ago, there was concern that terbinefine (Lamisil) causes significant liver trouble. In reality, as the medication has been on the market, it continues to develop a safer profile. https://www.tanglewoodfootspecialists.com/practice_areas/fungus-toenails-toenail-fungus-laser-houston-fungus-laser.cfm
