What Efudix is used for

What it does

Efudix is used to treat the following skin conditions:

  • Solar keratoses, also known as actinic keratoses or sun spots.
  • Bowen's disease (type of skin cancer).

Solar keratoses are rough, red, scaly, or crusty spots on the skin that are caused by too much exposure to sunlight. They are more common on sun-exposed areas, such as the face, nose, ears, chest, forearms, and back of the hands.

Solar keratoses are usually harmless, but there is a small risk that they may eventually turn into skin cancer.

Bowen's disease causes one or more small patches of scaly red skin. It occurs when there is a growth of abnormal cells in the outer layer of skin. It is most commonly found on the lower leg.

Ask your doctor if you have any questions about why Efudix has been prescribed for you. Your doctor may have prescribed Efudix for another reason.

How it works

Efudix contains the active ingredient fluorouracil.

Flurouracil belongs to a group of medicines called anti-cancer medicines (also called anti-neoplastic or cytotoxic medicines) that are applied to the skin.

It works by destroying precancerous and cancerous cells, while having little effect on normal cells.

Efudix is available only with a doctor's prescription.

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

To use Efudix follow these steps:

  • Apply Efudix as advised by your doctor.
  • Using a non-metal applicator, cotton bud or a rubber glove; apply a thin layer of Efudix to the affected areas of your skin. Do not use too much cream.
  • Be very careful not to allow Efudix to come into contact with mucous membranes, such as eyes, eyelids, nostrils and lips.
  • Wash your hands carefully and thoroughly immediately after using Efudix.
  • If your doctor asks you to apply an occlusive dressing after using Efudix, apply a fresh occlusive dressing to the area(s) daily.
  • The total area of skin treated with Efudix at any time should not exceed 500 sq cm (approx. 23 x 23 cm). Treat larger areas a section at a time.

When to use Efudix

Apply Efudix once or twice daily as advised by your doctor. Apply in the morning and then again in the late afternoon or early evening.

Do not apply Efudix immediately before going to bed. Contact with pillows or sheets may result in undesirable spreading of Efudix to normal skin that does not need treatment.

Use your medicine at about the same time each day. Using Efudix 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. Continue treatment up until the ulceration stage, usually 3 to 4 weeks. The healing process is usually complete 1 to 2 months after the end of treatment. The healthy skin surrounding the treated area may occasionally become reddened, but will soon resume 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 (overdose) or swallow the cream

Immediately telephone your doctor or the Poisons Information Centre (tel: 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you get Efudix in your eyes, nose or mouth or you think that you or anyone else may have used too much Efudix. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are using Efudix

Expect your appearance to look worse and to feel uncomfortable while treatment is in progress.

Sometimes it can take several weeks after treatment with Efudix has stopped 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.
  • The treated skin will then flake away.
  • Some redness of the skin will continue for some time after Efudix is stopped. Scarring is not expected.

Things you must do

Limit your exposure to sun during and immediately following treatment with Efudix. This will help reduce the likelihood and severity of unwanted side effects.

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 your doctor tells you to.

Do not stop using Efudix or change the dose without checking with your doctor.

Do not let Efudix come into contact with the eyes, eyelids, nostrils or mouth. 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 the sun or other forms of UV radiation for prolonged periods. This may increase irritation in the areas being treated.
  • Treatment around the eyes, nose or mouth unless directed by your doctor.
