As of 2015, there are no associated side effects with using laser therapy in treating fungal infections, particularly toenail fungus. This is in contrast with oral medications, such as Lamisil, which are known to cause renal problems, loose bowel movements, skin breakouts, headaches and changes in taste, states the Washington Post.
PinPointe laser is a device approved by the United States Food and Drug Administration in treating toenail fungus, which is medically referred to as onychomycosis. The procedure is safe and painless, notes Associated Podiatrists.
Among the 400 to 500 patients treated using PinPointe laser, there were no documented cases where a patient developed adverse side effects, claims Dr. Stephen J. Kominsky, a podiatrist from Washington. The success rate for laser therapy is also higher compared to oral treatment.
