Medical Treatments for Severe Fingernail Fungus

Fingernail fungus, also known as onychomycosis, is a common and persistent condition that affects many individuals. It occurs when a fungus infects one or more of your fingernails, causing them to become brittle, discolored, and thickened. While mild cases can often be treated with over-the-counter remedies, severe cases of fingernail fungus may require medical treatments for effective resolution.

Prescription Medications

In severe cases of fingernail fungus, prescription medications may be necessary to combat the infection. These medications are typically antifungal drugs that work by targeting the underlying cause of the infection.

Oral Antifungal Medications

The most commonly prescribed oral antifungal medication for severe fingernail fungus is terbinafine. It is highly effective in treating fungal nail infections and is taken daily for several weeks or months, depending on the severity of the infection. Terbinafine works by inhibiting the growth of the fungus and gradually clearing the infected nail.

Another oral antifungal medication, itraconazole, is also used to treat severe cases of fingernail fungus. Itraconazole is often prescribed in pulse-dose therapy, where it is taken for one week per month over a period of three to four months. This intermittent dosing schedule enhances the effectiveness of the medication while minimizing potential side effects.

Antifungal Nail Lacquers

In addition to oral medications, your doctor may also prescribe antifungal nail lacquers. These topical treatments are applied directly to the infected nails and are generally used in conjunction with oral antifungal medications. The lacquers contain antifungal agents that penetrate the nail to reach and eliminate the fungus.

Ciclopirox and amorolfine are commonly prescribed antifungal nail lacquers. They are usually applied once or twice a week and require consistent, long-term use to achieve noticeable improvement. Antifungal nail lacquers are well-tolerated and can be a useful alternative in cases where oral medications are not suitable.

Debridement and Surgery

In severe cases of fingernail fungus where the infection has caused significant nail damage or pain, your doctor may recommend debridement or surgery as part of the treatment plan.

Debridement

Debridement involves the removal of the infected nail material to reduce fungal load and to allow antifungal medications to reach the affected area more effectively. This can be done by your doctor using specialized instruments to trim or thin the nail. Debridement can be combined with topical or systemic antifungal treatments to enhance the efficacy of the medications.

Surgical Procedures

In severe and resistant cases of fingernail fungus, surgical procedures such as nail avulsion or matrixectomy may be considered. Nail avulsion involves the surgical removal of the entire nail plate if it is severely damaged or if other treatments have failed. Matrixectomy is a procedure that involves the destruction or removal of the nail matrix, where the nail grows from, to prevent future nail regrowth. These surgical procedures are typically performed under local anesthesia.

Combination Therapy

Combination therapy, combining different treatment approaches, may be employed in severe cases of fingernail fungus to increase the chances of successful eradication. It often involves a combination of oral antifungal medications, topical treatments, and debridement procedures. The goal of combination therapy is to target the fungus from multiple angles and improve treatment outcomes.

Medical treatments for severe fingernail fungus should always be administered under the guidance and supervision of a qualified healthcare professional. While these treatments can effectively eliminate the infection, it is important to follow the prescribed treatment plan consistently and be patient, as it may take several months for a new, healthy nail to grow.
