Griseofulvin is a medicine which is used to treat fungal infections. It is mainly prescribed for infections occurring on the skin or scalp. It is prescribed in particular for an infection called scalp ringworm (also called tinea capitis). It is also used to treat some nail infections, especially when other more frequently prescribed treatments are not suitable for some reason.
Before taking griseofulvin
Torna ai contenutiSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking griseofulvin it is important that your doctor knows:
Se sei incinta, stai cercando di avere un bambino o stai allattando.
If you have problems with the way your liver works.
If you have an inflammatory condition called systemic lupus erythematosus (SLE). Griseofulvin can make this condition worse.
Se hai un raro disturbo ereditario del sangue chiamato porfiria.
Se hai mai avuto una reazione allergica a un medicinale.
If you, or your partner, are using hormonal methods of contraception ('the pill').
Se stai assumendo altri medicinali. Questo include qualsiasi medicinale che stai assumendo e che è disponibile per l'acquisto senza prescrizione medica, così come i medicinali a base di erbe e complementari.

How to take griseofulvin
Torna ai contenutiBefore you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The manufacturer's leaflet will give you more information about griseofulvin and a full list of side-effects which you may experience from taking it.
Take griseofulvin exactly as your doctor tells you to. The usual dose for adults is 500-1000 mg each day. This can often be taken as a single daily dose, although your doctor may recommend that you take it divided into smaller doses spaced throughout the day. Doses for children depend upon the weight of the child. Children may be prescribed low-strength (125 mg) tablets to take, or oral liquid medicine.
Swallow the tablets whole with a drink of water. It is important that you take your doses of griseofulvin after a meal or snack. This is because the presence of food in your stomach helps your body to absorb the medicine properly.
If you forget to take a dose, take it as soon as you remember, unless it is nearly time for your next dose, in which case leave out the forgotten dose. Do not take two doses together to make up for a missed one.
Ottenere il massimo dal tuo trattamento
Torna ai contenutiTry to keep your regular appointments with your doctor. This is so your doctor can check on your progress. Treatment with griseofulvin may last from a few weeks to several months. It is important that you continue to take it until the infection has completely cleared, and then for a further two weeks afterwards.
If you drink alcohol, ask your doctor for advice about drinking whilst taking griseofulvin. Griseofulvin can increase the effects of alcohol and may not be recommended for you.
You must avoid getting pregnant or fathering a child while you are taking griseofulvin. In addition, women should avoid getting pregnant for at least a month after the treatment has finished, and men should avoid fathering a child for at least six months afterwards.
Make sure you discuss with your doctor which types of contraception are suitable for you and your partner. This is particularly important if you normally rely on hormonal contraception ('the pill'), as griseofulvin reduces its effectiveness.
If you buy or take any over-the-counter medicines, check with your doctor or a pharmacist that they are suitable for you to take with griseofulvin.
A few people taking griseofulvin find that their skin becomes more sensitive to sunlight. Protect your skin from bright sunlight until you know how your skin reacts, and do not use sunbeds.
If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking griseofulvin.
