What medication should be used for thickened toenails?

Thickened toenails should be treated with antifungal medications used for onychomycosis (fungal nail infection); medication selection must follow a physician’s instructions. Thickened toenails are often caused by onychomycosis, and prompt medical evaluation is recommended upon noticing this change. Under a doctor’s guidance, topical antifungal agents may be prescribed, or oral antifungal medications may be considered. During treatment, maintaining good personal hygiene is essential—before applying topical medication, wash the affected area thoroughly with warm water. Additionally, avoid spicy foods while taking oral antifungal drugs. With consistent, proper use of the prescribed medication, favorable outcomes can generally be expected.
