Antifungal medication in tablet is one of the ways your doctor can help you get rid of toenail fungus. Terbinafine (Lamisil) and Itraconazole (Sporanox) are the most common and effective oral medications. Your dermatologist might advise oral medication to treat your fungal nail infection. After taking a tablet of antifungal medication in the form of tablets or pills the medicine enters your bloodstream and reaches your nail.
Anti fungal medications can cause side effects ranging from headaches, skin rashes, and nausea to liver damage. In very rare occasions patients experience liver failure that can even result in death. Doctors avoid recommending these medications to patients with heart failure or liver disease.
Oral medications kill the fungus and new clear nail grow, gradually replacing the infected nail. Typically, oral medications are taken for 3 months or more. It takes at least 6 months to get rid of the fungal infection this way. Recurrent infections can happen if you don’t take the entire course of oral antifungal pills or continue to expose your nails to dark and damp environment (shoes for example).
Oral medication often clear any other fungal skin infections present in the body or on the skin.
