Will the oral medication to treat toenail fungus hurt my liver?


Our office continues to be open to all new and existing patients. We use hospital-grade sanitizers and are taking measures to ensure patients maintain social distancing by not having anyone wait in our reception room with others. If you prefer to wait in your car, just give us a call and we will call or text you when we are ready to bring you straight into a treatment room. Our entire staff is wearing masks and we encourage you to do the same.

For those patients who cannot or still wish not to visit the office, we are offering private video telemedicine visits. Simply call the office at 713-785-7881 and ask for an e-visit and we will be happy to get you set up for an immediate appointment. You can also request an appointment through our website.

oral lamisil medication to treat Houston toenail fungusThere are a few different medications available to treat toenail fungus. The most common is Lamisil (generic is terbinafine). Lamisil has been available for over 15 years and has been found to be approximately 85% effective in eliminating toenail fungus. The long-term followup has been fantastic as well.


When Lamisil first came to market, there was concern about the effect on the liver. Over the years, the safety profile has improved and the medication carries no "black box warnings." As a Houston foot doctor who treats toenail fungus on a daily basis, I do still take a baseline blood test to ensure your liver is functioning in the normal range, since we do know that Lamisil is metabolized  in the liver. If your liver is functioning normally, I am confident and comfortable prescribing the medication.


I understand when people don't want to take medication because of side effects, but oral Lamisil and its generics are very safe and I have effectively prescribed it for patients from their teenage years until their 90's, all with excellent results. There are alternatives for oral medication, however. To have your fungal toenails evaluated and to discuss the best treatment for you, contact Houston podiatrist Dr. Andrew Schneider.
