I'm worried about the side effects from taking Lamisil (terbinafine) for skin fungus. How can I avoid them?
2 weeks treatment. The usual treatment for skin fungal infection with Lamisil (terbinafine) is 2 weeks. Unless you are at a high risk for complications from other comorbidities, the use of Lamisil (terbinafine) for 2 weeks is very safe. However, there are some very effective topical medications that may get the job done without the pills.
