This medication is used to treat fungal infections of the skin, hair, and nails that do not respond to creams/lotions. Clearing such infections will get rid of symptoms such as itching, red/peeling/scaly skin, and discolored nails. This medication works by stopping the growth of fungi. It does not treat infections due to bacteria or yeast.
How to use Griseofulvin Tablet
Take this medication by mouth as directed by your doctor. For the best absorption, it is best taken with or after a meal containing a moderate amount of fat. Talk to your doctor or pharmacist about specific dietary instructions, especially if you are on a low-fat diet.
The dosage is based on your medical condition and response to therapy. In children, dosage is also based on weight. The length of treatment depends on the type of infection you have. It may take several weeks to months to complete treatment for infections of the scalp, feet, and body. Nail infections may require several months to a year or longer to treat.
Continue to take this medication for the full prescribed length of treatment even if symptoms improve after a few days. Stopping the medication too early may allow the fungus to continue to grow, which may result in a relapse of the infection.
Inform your doctor if your condition persists or worsens.
