How to Treat Thickened Toenails

Some individuals overlook the thickening of toenails, allowing the condition to progress unchecked—potentially leading to further complications. It is important to understand that toenail thickening can stem from various causes, including congenital factors and tinea pedis (athlete’s foot). So, how should thickened toenails be treated? The specific approaches are outlined below:

How to Treat Thickened Toenails

1. Proper Trimming

When toenail thickening is still mild, appropriate nail trimming may suffice as treatment. Begin by soaking both feet in warm water to soften hardened keratin and improve local circulation. After soaking, gently trim the softened, thickened nail using a cuticle knife. Take care to perform trimming motions gently—avoid excessive force, which could injure the skin surrounding the nail.

2. Topical Medication

Patients should first use a nail file to gradually thin irregular, dystrophic nails—once every two days. Subsequently, apply 30% acetic acid topically—or soak the affected nail in 10% acetic acid—once daily for at least three to six months. Following the soak, antifungal topical agents such as terbinafine solution, amorolfine nail lacquer, or ciclopirox nail lacquer may be applied locally. Prior to application, protect the perionychial skin with a gentle, non-irritating ointment.

3. Nail Debridement Therapy

Using a nail file or scalpel, carefully reduce the thickness of the affected nail once weekly. Concurrently, apply topical medication daily and occlude the nail (e.g., with a dressing), or alternate between daytime topical application and nighttime occlusion. This regimen typically lasts two to three months. During treatment, ensure adequate protection of the perionychial skin, and avoid alkaline soaps. Commonly used agents include iodine tincture, acetic acid, and antifungal ointments; however, specific drug selection must be guided by a physician’s advice.
