Griseofulvin

What Is Griseofulvin

Griseofulvin is a prescription antifungal medicine used to treat fungal infections of the skin, hair, and nails. A dermatologist usually prescribes this medicine. A dermatologist is a doctor who treats skin, hair, and nail diseases.

Fungal infections happen when tiny organisms called fungi grow on the body and spread in warm and moist areas.

These infections can cause itching, redness, scaling, and hair loss in affected areas.

Griseofulvin is mainly used when the infection is deeper or affects hair and nails, where surface creams are not enough.

It is available as oral tablets or liquid suspension.

The medicine is taken for a longer duration because fungal infections of hair and nails take time to fully clear.

What This Medicine Does in the Body

Griseofulvin works by stopping fungi from growing and spreading in the body.

Fungal cells need to divide and multiply to continue infection.

Griseofulvin interferes with this process by affecting the structure needed for cell division.

It binds to a protein called keratin in the skin, hair, and nails.

Keratin is a natural protein that forms the outer structure of these tissues.

When new skin, hair, or nails grow, they become resistant to fungal infection because of the presence of the medicine.

This helps infected tissues slowly get replaced with healthy tissue.

The medicine does not kill fungi instantly. Instead, it stops them from growing so the body can clear the infection over time.

Uses of Griseofulvin / Griseofulvin Used For

Doctors prescribe Griseofulvin mainly for fungal infections of the skin, hair, and nails.

It is commonly used for ringworm infections of the body and scalp.

Ringworm is a fungal infection that causes round, itchy, red patches on the skin.

The medicine is also used for tinea capitis, which is a fungal infection of the scalp that can cause hair loss and itching.

It may be used for fungal infections of nails, although treatment in nails may take several months.

Griseofulvin is often preferred in children for scalp infections under medical supervision.

It is not usually used for mild fungal infections that can be treated with creams.

Treatment duration depends on the type and severity of infection.

How Griseofulvin Works

Griseofulvin works by stopping fungal cell division.

Fungi need to divide to spread infection in skin, hair, and nails.

The medicine interferes with the formation of fungal cell structures needed for this division.

It also binds tightly to keratin in skin, hair, and nails.

As new keratin is formed, it becomes resistant to fungal invasion.

This means the fungus is gradually pushed out as new healthy tissue grows.

Over time, the infection clears as infected tissue is replaced.

Because of this slow process, treatment must be continued for several weeks or months.

Doctors may recommend taking the medicine with fatty food to improve absorption.

Side Effects of Griseofulvin

Like all medicines, Griseofulvin may cause side effects, although not everyone experiences them.

Some patients may feel headache, nausea, or stomach discomfort.

Dizziness or tiredness may occur in some individuals.

Skin rash or itching may develop in sensitive patients.

Rarely, sensitivity to sunlight may increase, causing sunburn more easily. This is called photosensitivity.

Some people may experience changes in taste or mild confusion.

Very rarely, liver-related problems may occur, especially with long-term use.

Patients should avoid alcohol during treatment, as it may increase side effects.

Doctors may monitor liver function during long-term therapy.

Patients should seek medical help if they develop severe rash, yellowing of eyes, or unusual fatigue.
