Discovered in 1939 as a derivative of penicillin, Griseofulvin is an antifungal drug that is available as a liquid oral suspension, in a tablet or in a capsule format. Whether used after topical treatments have failed or as a booster to the topical treatments, Griseofulvin has a direct effect on infections that are fungal in nature. Griseofulvin is on the WHO's list of essential medicines, which are the safest and most effective medicines known in the world.
Griseofulvin works on several fungal infections such as cradle cap and ringworm. Symptoms that patients with these conditions suffer include red, scaly, peeling skin, discolored nails and itching. Griseofulvin is sold under the marketing names Fulvicin, Grifulvin and Gris-PEG.
Griseofulvin works by inhibiting the growth of fungi, stopping the infection from becoming worse or more widespread while the body replaces the unhealthy cells with healthy ones, eventually killing the fungal infection.
Fungal infections occur frequently in humans, when a fungus takes over a portion of the body and proves too much for the body's own immune system. Though some fungi are natural and necessary to the human body, harmful ones can be difficult to get rid of and often repeat themselves.
People with weakened immune systems are more prone to fungal infections, which would include patients undergoing cancer treatment and diabetics as well as HIV positive patients. Common fungal infections include athlete's foot, yeast infections, jock itch and ring worm.
Griseofulvin may create adverse symptoms in healthy parts of the body by doing its work of bonding with fungal cells. If you experience any of the following adverse health effects, notify your doctor immediately:
Other symptoms may also happen that may disappear with time, but if you notice them becoming prolonged or severe, they should be reported to your physician:
Still other effects may occur in some patients, so if you experience any health changes after you start taking Griseofulvin; it is advised that you report these to your physician.
Griseofulvin should be continued for the full duration of the prescription your doctor has written for you. Discontinuing the use of this medication when your symptoms clear up may not kill the entire infection.
Maintain good hygiene during your treatment period to control the infection and stop it from reoccurring.
Griseofulvin is best absorbed by the body if it is taken with a meal that contains a high amount of fat. Drinking whole milk or eating ice cream or having a meal such as a cheeseburger with Griseofulvin is recommended.

Tablets should be taken whole or crushed and distributed in a tablespoon of applesauce, which should then be swallowed and not chewed up.
