Nail fungus, also known as onychomycosis, is a common condition that can affect both fingernails and toenails. It is caused by fungal infections that can lead to discoloration, thickening, and crumbling of the nails. If you suspect you have nail fungus, it is essential to seek medical advice for an accurate diagnosis and appropriate treatment plan. Here are some common treatments for nail fungus: Topical antifungal medications: Over-the-counter antifungal creams, lotions, and nail paints can be used for mild cases of nail fungus. These products are applied directly to the affected nails and surrounding skin. Prescription oral antifungal medications: In more severe cases or when topical treatments are ineffective, doctors may prescribe oral antifungal medications. These medications are taken by mouth and can be more potent in treating the infection. Medicated nail polish: Prescription-strength antifungal nail polish (ciclopirox) may be recommended for milder cases of nail fungus.
