1. Why am I using FLUOROURACIL VIATRIS?

FLUOROURACIL VIATRIS contains the active ingredient fluorouracil. FLUOROURACIL VIATRIS belongs to a group of anti-cancer medicines that are applied to the skin. It works by destroying precancerous and cancerous cells, while having little effect on normal cells.

FLUOROURACIL VIATRIS is used to treat the following skin conditions:

• Solar keratoses, also known as actinic keratoses or sunspots.
• 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.

2. What should I know before I use FLUOROURACIL VIATRIS?

Warnings

Do not use FLUOROURACIL VIATRIS if:

• you are allergic to fluorouracil, or any of the ingredients listed at the end of this leaflet.
• Always check the ingredients to make sure you can use this medicine.
• You have a dihydropyrimidine dehydrogenase (DPD) enzyme deficiency.

Check with your doctor if you:

• have any other medical conditions including inflammatory skin conditions such as darkening of skin during pregnancy (chloasma) or a chronic rash (rosacea).
• Work outside for long periods of time during the day.
  Exposure to UV radiation from the sun or tanning salons may increase the intensity of skin reactions at the sites where FLUOROURACIL VIATRIS is applied.
• Take any medicines for any other condition.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Do not use FLUOROURACIL VIATRIS if you are pregnant or intend to become pregnant. FLUOROURACIL VIATRIS may affect your developing baby if you use it during pregnancy.

Talk to your doctor if you are breastfeeding or intend to breastfeed. Nursing mothers should avoid using FLUOROURACIL VIATRIS as it is not known if the active ingredient in FLUOROURACIL VIATRIS passes into breast milk, and if there is a possibility that your baby may be affected.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with FLUOROURACIL VIATRIS and affect how it works.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect FLUOROURACIL VIATRIS.

4. How do I use FLUOROURACIL VIATRIS?

How much to use

Apply FLUOROURACIL VIATRIS to the affected skin once or twice daily as advised by your doctor.

Follow the instructions below and use FLUOROURACIL VIATRIS until your doctor tells you to stop.

• Wash the skin to be treated using lukewarm water. Avoid soap or other cleansing products which may sting or irritate your skin, especially as treatment progresses.
• Pat dry the affected area with a soft white paper towel.
• Allow 15 minutes for your skin to completely dry.
• Using a non-metal applicator, cotton bud or a rubber glove apply a thin film of FLUOROURACIL VIATRIS, smoothing it gently onto your affected skin. Do not use too much cream.
• Be very careful not to allow FLUOROURACIL VIATRIS to come into contact with mucous membranes, such as eyes, eyelids, nostrils and lips.
• Do not apply FLUOROURACIL VIATRIS to broken skin or open cuts as it is may be absorbed into the bloodstream and may cause side effects.
• Wash your hands carefully and thoroughly immediately after using FLUOROURACIL VIATRIS.
• Do not cover the treated area unless your doctor tells you to.
• If your doctor asks you to apply a dressing after using FLUOROURACIL VIATRIS, apply a fresh dressing to the area(s) daily.
• The total area of skin treated with FLUOROURACIL VIATRIS at any time should not exceed 500 sq cm (approx. 23 cm x 23 cm). Treat larger areas a section at a time.

When to use FLUOROURACIL VIATRIS

• Apply in the morning and then again in the late afternoon or early evening.
• Do not apply FLUOROURACIL VIATRIS immediately before going to bed.
• Apply FLUOROURACIL VIATRIS at least 1.5 - 2 hours before bedtime to enable complete absorption and prevent wiping off onto pillowcases and sheets. Contact with pillowcases or sheets may result in undesirable spreading of FLUOROURACIL VIATRIS to normal skin that does not need treatment.

How long to use FLUOROURACIL VIATRIS

Unless your doctor tells you to stop using FLUOROURACIL VIATRIS 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 FLUOROURACIL VIATRIS

FLUOROURACIL VIATRIS should be used regularly at the same time each day.

If you miss your dose at the usual time and it is almost time for your next dose, skip the dose you missed and apply your next dose when you are meant to.

Do not try to make up the dose you missed by applying more the next time.

If you use too much FLUOROURACIL VIATRIS

If you think that you have used too much FLUOROURACIL VIATRIS, you may need urgent medical attention.

You should immediately:

• phone the Poisons Information Centre
  (Australia telephone 13 11 26) for advice, or
• contact your doctor, or
• go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using FLUOROURACIL VIATRIS?

What you should expect

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

Sometimes it can take several weeks after treatment with FLUOROURACIL VIATRIS has stopped before you see any improvement in your condition.

When FLUOROURACIL VIATRIS is applied to the skin, the following usually happens:

• Redness of the affected area occurs (generally within 3 to 5 days).
• This is 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 FLUOROURACIL VIATRIS is stopped. Scarring is not expected.

Things you should do

• Limit your exposure to sun during and immediately following treatment with FLUOROURACIL VIATRIS.

This will help reduce the likelihood and severity of unwanted side effects.

• Apply a broad-spectrum sunscreen (SPF 30 or higher) every day before going outdoors, and regularly reapply during the day, except directly on the treatment area.

FLUOROURACIL VIATRIS can make you more sensitive to sunlight. In addition to sunscreen, wear wide-brimmed hat, long sleeves, and trousers (or a long skirt) to protect your skin.

Call your doctor straight away if you:

• Become pregnant while using FLUOROURACIL VIATRIS.

Remind any doctor, dentist or pharmacist you visit that you are using FLUOROURACIL VIATRIS.

Things you should not do

Do not let FLUOROURACIL VIATRIS come into contact with the eyes, eyelids, nostrils or mouth. FLUOROURACIL VIATRIS is highly irritating to sensitive skin and the eyes.

Things to be careful of

While treatment is in progress follow these personal care tips:

• Avoid using cosmetics or other topical medications, including sunscreens, directly on the treatment area, unless directed by your doctor.

Your treated skin is expected to become irritated and uncomfortable whilst using FLUOROURACIL VIATRIS.

Applying other products directly on the treatment area may make your discomfort worse.

• You may continue to shave whilst using FLUOROURACIL VIATRIS but take care not to cut your skin in the treatment area.

As facial skin becomes inflamed during FLUOROURACIL VIATRIS treatment shaving with a conventional razor may become unpleasant. You may prefer instead to lightly shave with an electric razor or clip the facial hair.

Looking after your medicine

Store below 25°C. Protect from heat.

Follow the instructions in the carton on how to take care of your medicine properly.

FLUOROURACIL VIATRIS_cmi\Apr24/00

Published by MIMS May 2024

1 Name of Medicine

Fluorouracil.

2 Qualitative and Quantitative Composition

Contains fluorouracil 5% w/w as the active ingredient.

Excipients with known effect.

3 Pharmaceutical Form

Cream.

4 Clinical Particulars

4.1 Therapeutic Indications

Solar and senile keratoses, Bowen's disease.

4.2 Dose and Method of Administration

Fluorouracil Viatris should only be used under medical supervision.
Fluorouracil Viatris is well tolerated. The healthy skin surrounding the area being treated may occasionally become reddened, but soon resumes its normal colour on cessation of treatment.
In cases of senile and solar keratoses a thin layer of the cream is applied to the affected areas once or twice daily, generally without a dressing. In the treatment of other conditions (including keratosis palmaris) a fresh occlusive dressing should be applied daily. Treatment should be continued up to the erosion stage. Duration of therapy is usually 3-4 weeks, but it may prove necessary to exceed this on occasion. When Fluorouracil Viatris 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.

Limitation of treatment area.

4.3 Contraindications

Fluorouracil is contraindicated in women who are or may become pregnant during therapy (see Section 4.6 Fertility, Pregnancy and Lactation).
Known hypersensitivity to fluorouracil or any of its excipients.
Fluorouracil should not be used in patients with dihydropyrimidine dehydrogenase (DPD) enzyme deficiency. A large percentage of fluorouracil is catabolised by the enzyme dihydropyrimidine dehydrogenase. DPD enzyme deficiency can result in shunting of fluorouracil to the anabolic pathway, leading to cytotoxic activity and potential toxicities.
Rarely, life-threatening toxicities such as stomatitis, diarrhoea, neutropenia, and neurotoxicity have been reported with intravenous administration of fluorouracil in patients with DPD enzyme deficiency.
A case of life-threatening systemic toxicity has been reported with the topical use of fluorouracil 5% in a patient with DPD enzyme deficiency. Symptoms included severe abdominal pain, bloody diarrhoea, vomiting, fever, and chills. Physical examination revealed stomatitis, erythematous skin rash, neutropenia, thrombocytopenia, inflammation of the oesophagus, stomach, and small bowel. Although this case was observed with 5% fluorouracil cream, it is unknown whether patients with profound DPD enzyme deficiency would develop systemic toxicity with lower concentrations of topically applied fluorouracil.

4.4 Special Warnings and Precautions for Use

The normal pattern of response includes: early and severe inflammatory phases (typically characterised by erythema, which may become intense and blotchy), a necrotic phase (characterised by skin erosion) and finally healing (when epithelialisation occurs). The clinical manifestation of response usually occurs in the second week of fluorouracil treatment. However, these treatment effects sometimes are more severe and include pain, blistering and ulceration.
Fluorouracil is highly irritant, and so should not be allowed to come in contact with mucous membranes (eyes, nose or mouth) due to the possibility of irritation, local inflammation and ulceration. There is a possibility of increased absorption through ulcerated or inflamed skin.
Treatment of perioral area or nasolabial fold should be avoided, or treated carefully. Because of its irritant nature, care should be taken to ensure that fluorouracil does not come into contact with normal skin. Fluorouracil should be applied with a non-metal applicator or rubber glove. Should a glove not be worn and the hands come in contact with fluorouracil during application they should be washed thoroughly after applying fluorouracil.
Exposure to UV-radiation, (e.g. natural sunlight or tanning salon) should be avoided. Fluorouracil therapy is not advisable in persons who work outdoors for prolonged periods in the sun. Excessive sun exposure may produce a diffuse phototoxic response in the areas of application; therefore exposure should be minimised during and immediately following treatment with fluorouracil because the intensity of the reaction may be increased.
While treatment is in progress, avoid cosmetics on treated areas and other topical medication applied to the same area, unless otherwise directed.
Occlusion of the skin with resultant hydration has been shown to increase percutaneous penetration of several topical preparations. If any occlusive dressing is to be used, there may be an increase in the severity of inflammatory reactions in the adjacent normal skin. A porous gauze dressing may be applied for cosmetic reasons without increase in reaction.
The excipients stearyl alcohol and propylene glycol may cause local skin irritations (e.g. contact dermatitis); the excipients methyl hydroxybenzoate and propyl hydroxybenzoate may cause allergic reactions (possibly delayed).

Use in the elderly.

Paediatric use.

Effects on laboratory tests.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Although no significant medicine interactions with fluorouracil have been reported, potential medicine interactions are possible, caution should be taken with medicines that may have an effect on the DPD enzyme.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

The most frequently encountered reactions are often related to an extension of the pharmacological activity of the medicine. These include pain, pruritus, hyperpigmentation, burning, crusting, allergic contact dermatitis, erosions, erythema, hyperpigmentation, irritation, photosensitivity, scarring, rash, soreness and ulceration at the site of application. Leukocytosis is the most frequent haematological adverse effect.
Application site haemorrhage has also been reported (frequency unknown).
The patient should be advised of the temporary unsightly appearance and local discomfort to be expected during treatment with this drug (see Section 4.4 Special Warnings and Precautions for Use). Patients with chloasma and rosacea and other inflammatory dermatoses may encounter accentuation of their condition and should first be treated with appropriate therapy before using the medication. While absorption of fluorouracil through healthy skin is negligible, absorption is considerably increased when it is applied to diseased skin.
Although a causal relationship is remote, other adverse reactions which have been reported infrequently are:

Nervous system disorders.

Gastrointestinal disorders.

Skin and subcutaneous tissue disorders.

Special senses.

Miscellaneous.

Reporting suspected adverse effects.

4.9 Overdose

If fluorouracil is accidentally ingested, signs of fluorouracil overdosage may include nausea, vomiting and diarrhoea. Stomatitis and blood dyscrasias may occur in severe cases. Appropriate measures should be taken for the prevention of systemic infection and daily white cell counts should be performed.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).
