What Efudix is used for

Efudix is used to treat:

  • Solar keratosis
  • Bowens disease (type of skin cancer)

It contains the active ingredient fluorouracil. Efudix belongs to a group of medicines called topical anti-cancer (also called anti-neoplastic or cytotoxic) drugs.

Topical anti-cancer drugs are used on the skin to treat conditions caused by ageing or exposure to sunlight (solar keratoses). If left untreated, these conditions may develop into skin cancer.

Efudix is also used to treat Bowen's disease, which is a type of skin cancer.

You should be aware that you may look worse while treatment is in progress before you see any improvement in your condition.

When Efudix is applied to the skin, the following usually happens: a redness of the affected area (generally within 3 to 5 days) followed by blistering, peeling, and cracking (within 11 to 14 days) with occasional open sores and some discomfort. Although the skin seems to be worse, it is a sign that the medication is working. The treated skin will flake away. Some redness of the skin will continue for some time after the drug is stopped. Scarring would not be expected.

Ask your doctor if you have any questions why Efudix has been prescribed for you .

Your doctor, however, may have prescribed Efudix for another purpose.

This medicine is available only with a doctor's prescription.

Before you use Efudix

When you must not use it

  • any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

Do not use this medicine if you have a dihydropyrimidine dehydrogenase (DPD) enzyme deficiency.

Do not use this medicine if you are pregnant or planning to become pregnant.

It may affect your developing baby if you use it during pregnancy.

Do not breast-feed if you are using this medicine.

It is not known if the active ingredient in Efudix passes into breast milk and there is a possibility that your baby may be affected.

Do not use Efudix after the expiry date (EXP) printed on the pack or if the packaging is torn or shows signs of tampering.

If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure if you should be using Efudix, talk to your doctor.

Before you start to use it

Tell your doctor if you have allergies to any other medicines, foods, dyes or preservatives.

Tell your doctor if you have any other health problems including:

  • inflammatory skin conditions such as darkening of skin during pregnancy (chloasma) or a chronic rash (rosacea)

How to use Efudix

Follow all directions given to you by your doctor or pharmacist carefully.

They may differ from the information contained in this leaflet.

How to use it

Follow these steps to using Efudix :

  • Apply Efudix as advised by your doctor.
  • Apply a thin layer of Efudix to the affected areas of your skin. Avoid eyelids, nose and lips.
  • Apply Efudix preferably with a non-metal applicator or a rubber glove. If you use your fingers to apply Efudix or your hands come into contact with Efudix wash them thoroughly. Do this immediately after use.
  • Although not generally required, your doctor may recommend that you apply a fresh occlusive dressing to the area(s) daily.
  • Always follow your doctors' directions and apply Efudix for the length of time that has been prescribed to achieve the best results. If you have any questions call your doctor and be sure to keep your scheduled appointments.

The total area of skin being treated with Efudix at any time should not exceed 500cm2 (approx. 23 x 23 cm) Larger areas should be treated a section at a time.

As you use Efudix cream, the area of skin you are treating will probably become red and swollen. The top layer of skin will then be lost before it begins to heal.

When to use Efudix

Apply Efudix once or twice daily as advised by your doctor. It should be applied in the morning and late afternoon or early evening. Do not apply Efudix immediately before going to bed.

Use your medicine at about the same time each day.

Using it at the same time each day will have the best effect. It will also help you remember when to use it.

How long to apply Efudix

Continue using Efudix for as long as your doctor has told you to.

Treatment should continue up until the ulceration stage, usually three to four weeks. The healing process is usually complete one to two months after the end of treatment. The healthy skin surrounding the area being treated may occasionally become reddened, but soon resumes its normal colour once treatment is stopped.

If you forget to use it

Do not try to make up for the application you missed by applying more at the next application.

If you are not sure what to do, ask your doctor or pharmacist.

If you use too much or ingest the cream (overdose)

Immediately telephone your doctor or the Poisons Information Centre (Australia 13 1126; New Zealand 800 764 766) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have used too much or ingested Efudix. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

Incorrect use of Efudix may result in more sever irritation of the skin around the areas being treated. This will subside when the treatment is stopped.

While you are using Efudix

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are using Efudix.

Tell any other doctors, dentists, and pharmacists who treat you that you are using this medicine.

If you become pregnant while using Efudix stop using it and tell your doctor immediately.

Keep all of your doctor's appointments so that your progress can be checked.

Always discuss with your doctor any problems or difficulties experienced during or after using Efudix.

Things you must not do

Do not give your medicine to anyone else, even if they have the same condition as you.

Do not use Efudix to treat other complaints unless advised to by your doctor.

Do not stop using your medicine or lower the dosage without checking with your doctor.

Do not let Efudix come into contact with mucous membranes or the eyes.

Efudix is highly irritating to sensitive skin and the eyes.

Things to be careful of

While treatment is in progress, avoid:

  • cosmetics or other topical medication applied to the treatment area, unless directed by your doctor.
  • exposing treated areas to sun (ultraviolet rays) during and immediately following treatment because the intensity of the reaction may be increased. This may increase irritation in the areas being treated.
  • treatment around the eyes, nose or mouth unless directed by your doctor.
  • Be aware that you may look worse while treatment is in progress.
