This medication should never be frozen. USES This medication is used to treat certain fungal infections of the skin and nails. Griseofulvin prevents the multiplication of susceptible fungi. It also enters the cells of skin, hair, and nails, and protects them from fungal invasion. TREATMENT In order to avoid stomach irritation, you can take griseofulvin with food or milk. The oral suspension form of this medication should be shaken well, just before measuring each dose. The contents tend to settle on the bottom of the bottle, so it is necessary to shake the container to evenly distribute the ingredients and equalize the doses. Each dose should then be measured carefully with a specially designed, 5-ml measuring spoon. An ordinary kitchen teaspoon is not accurate enough. If you miss a dose of this medication, take the missed dose as soon as possible, unless it is almost time for the next dose. In that case, do not take the missed dose at all; just return to your regular dosing schedule. Do not double the next dose. It is important to continue to take this medication for the entire time prescribed by your doctor (perhaps six months or more), even if the symptoms disappear before the end of that period. If you stop taking this drug too soon, resistant fungi are given a chance to continue growing, and your infection could recur. SIDE EFFECTS Minor. Diarrhea, dizziness, fatigue, headache, insomnia, nausea, stomach upset, and vomiting. These side effects should disappear in several days, as your body adjusts to the medication. If you feel dizzy, sit or lie down awhile; get up slowly. This medication can increase your sensitivity to sunlight. You should therefore avoid prolonged exposure to sunlight and sunlamps. Wear protective clothing and sunglasses, and use an effective sunscreen. Major. Tell your doctor about any side effects that are persistent or particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about confusion, itching, skin rash, sore throat, or a tingling of the hands or feet. INTERACTIONS Griseofulvin interacts with other types of medication. 1. It can increase the effects of alcohol, resulting in flushing and an increased heart rate. 2. Barbiturates can cause a decrease in the effectiveness of griseofulvin. 3. Griseofulvin can decrease the effectiveness of oral anti-coagulants (blood thinners, such as warfarin). Before starting to take griseofulvin, BE SURE TO TELL YOUR DOCTOR if you are already taking any of these other medications. WARNINGS * Tell your doctor about unusual or allergic reactions you have had to any medications, especially to griseofulvin, penicillins, cephalosporin antibiotics, or penicillamine. * Before starting to take griseofulvin, be sure to tell your doctor if you now have, or if you have ever had, liver disease, porphyria, or systemic lupus erythematosus (SLE). * If this drug makes you dizzy, do not take part in any activity that requires alertness, such as driving a car or operating potentially dangerous equipment. * Observe good hygiene to control the source of infection and to prevent reinfection. * Concurrent use of an appropriate topical antifungal medication may be necessary to help clear the infection. * Be sure to tell your doctor if you are pregnant. Extensive studies in pregnant women have not yet been completed, but birth defects have been reported in animals whose mothers received large doses of griseofulvin during pregnancy. Also, tell your doctor if you are breast-feeding an infant. It is not known whether or not griseofulvin passes into breast milk. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
