Without a Prescription

Griseofulvin is prescribed for the treatment of the following ringworm infections:
- Ringworm of the scalp;
- Ringworm of the nails;
- Ringworm of the groin and thigh;
- Ringworm of the body;
- Barber's itch (inflammation of the facial hair follicles);

Because Griseofulvin is effective for only certain types of fungal infections, before treatment your doctor may perform tests to identify the source of infection.

To clear up your infection completely, continue taking Griseofulvin as prescribed until your doctor tells you to stop.
