Efudex Properties
About Efudex
Efudex is a prescription-only topical medication that contains the chemotherapeutic agent fluorouracil, available in 1 % and 5 % concentrations. It belongs to the antimetabolite class of drugs and is used primarily in skin-care to treat precancerous lesions such as actinic keratosis and certain superficial skin cancers. While its primary purpose is lesion clearance, dermatologists sometimes employ Efudex for off-label conditions when conventional therapies are unsuitable.
What is Efudex?
Efudex is a brand-name formulation of fluorouracil, a pyrimidine-analog antimetabolite that interferes with DNA synthesis in rapidly dividing cells. In Australia, the Therapeutic Goods Administration (TGA) approved Efudex for the topical treatment of actinic keratosis and superficial basal cell carcinoma. The product is supplied as a tube containing a cream base, and the 5 % strength is the most commonly prescribed. Efudex is manufactured by LEO Pharma, an internationally recognised company with a long history of dermatological innovations.
How Efudex Works
Fluorouracil mimics the structure of uracil, a natural nucleobase, and is incorporated into DNA during the S-phase of the cell cycle. Once inside the cell, it forms a stable complex with the enzyme thymidylate synthase, preventing the conversion of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP). This blockade halts the synthesis of thymidine-a nucleotide essential for DNA replication-and triggers apoptotic cell death.
When applied to the skin, only a small fraction of the drug penetrates the stratum corneum; systemic absorption is minimal, which limits systemic toxicity. Clinical response typically begins within 2-4 weeks of daily application, and full lesion resolution can take 4-6 weeks, depending on the concentration used and the lesion’s depth. The drug is metabolised locally by cellular enzymes into inactive metabolites, and any absorbed fluorouracil is rapidly cleared by the kidneys.
Why Efudex is Used for Skin-Care Conditions
- Actinic keratosis (AK): AK lesions consist of dysplastic keratinocytes that proliferate rapidly. By inhibiting DNA synthesis, Efudex selectively destroys these abnormal cells while sparing surrounding normal epidermis, leading to complete lesion clearance in 70-90 % of cases. Guidelines from the Australian Dermatology Society list topical fluorouracil as a first-line option for field therapy when multiple AKs are present.
- Superficial basal cell carcinoma (sBCC): sBCC is confined to the epidermis and upper dermis. Efudex penetrates sufficiently to eradicate tumour cells without the need for surgical excision, offering a cosmetically favourable alternative for lesions in cosmetically sensitive areas such as the face.
- Seborrheic keratosis (off-label): Small, raised keratotic lesions sometimes respond to fluorouracil, especially when patients prefer a non-surgical approach. Limited case series suggest partial clearance, but it remains off-label in Australia.
- Field cancerisation: In patients with extensive sun-damage, Efudex can be applied to a broad area, treating both visible lesions and subclinical dysplasia, thereby reducing the risk of future skin cancers.
Off-Label and Investigational Uses of Efudex
Although not approved by the TGA for these indications, several small studies have explored Efudex in the treatment of:
- Superficial melanoma in situ: Topical fluorouracil has shown partial regression in isolated case reports, but larger trials are lacking.
- Bowen’s disease: Controlled trials indicate a clearance rate of about 80 % with 5 % fluorouracil applied twice daily for six weeks.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Efudex Right for You?
Efudex is suitable for adults with histologically confirmed actinic keratosis or superficial basal cell carcinoma who can adhere to a daily application regimen. It is less appropriate for:
- Pregnant or breastfeeding individuals: Fluorouracil is teratogenic in animal studies, and systemic exposure, although low, is discouraged.
- Patients with severe hepatic or renal impairment: Reduced clearance may increase systemic levels, warranting dose adjustment or alternative therapy.
- Those with known hypersensitivity to fluorouracil or any cream excipients: A skin-test patch may be advisable before full-area treatment.
Elderly patients often tolerate Efudex well, provided they can manage the local inflammatory reaction that accompanies treatment.
Taking Efudex Effectively
- Application: Apply a thin, even layer to the entire affected area once daily, preferably in the evening. Avoid surrounding healthy skin; use a cotton swab for precise placement.
- Timing: Allow the cream to dry completely before dressing the area or applying other topical agents.
- Lifestyle integration: Sun protection is critical; use broad-spectrum sunscreen (SPF 30+) and protective clothing during treatment.
- Missed dose: If a dose is missed, apply it as soon as remembered unless it is close to the next scheduled dose; in that case, resume the regular schedule.
- Travel tips: Carry a small tube for touch-ups and keep the product in a cool, dry place to maintain potency.
Understanding Side Effects and How to Manage Them
The most common local reactions-redness, crusting, burning, and itching-are direct consequences of fluorouracil-induced cell death. These inflammatory signs usually peak 2-3 weeks after initiation and signal therapeutic activity. Management strategies include:
- Cool compresses: Apply a damp, cool cloth for 10-15 minutes several times daily to soothe burning.
- Topical emollients: Use fragrance-free moisturisers on the perilesional skin to reduce dryness and cracking.
- Analgesic gels: Over-the-counter lidocaine gels can lessen discomfort without interfering with drug action.
If severe ulceration, excessive pain, or signs of infection develop, patients should seek medical attention promptly. Systemic toxicity is rare but may present as nausea, vomiting, or cytopenias; immediate evaluation is required if systemic symptoms arise.

Frequently Asked Questions
-
How long will the treatment area look inflamed? The inflammatory phase typically lasts 2-4 weeks, after which the skin begins to heal and normal colour returns.
-
Can I apply Efudex to my face? Yes, it is commonly used on facial lesions, but extra caution is advised to avoid accidental spread to the eyes or mucous membranes.
-
What should I do if I develop a severe ulcer? Contact your prescribing clinician immediately; the ulcer may require a temporary pause in therapy or an alternative treatment.
-
Is it safe to use Efudex while on other topical medications? Most concomitant topicals can be applied to non-treated skin, but avoid layering another cream directly over Efudex, as it may dilute the active ingredient.
-
Does Efudex interact with systemic chemotherapy? Systemic fluorouracil chemotherapy can increase cumulative exposure; discuss any concurrent systemic therapy with your oncologist.
-
Can I use Efudex on nails affected by actinic damage? Topical fluorouracil penetrates poorly into the nail plate; dedicated nail-specific preparations are recommended instead.
-
Why does my skin peel after treatment? Peeling is a natural result of keratinocyte death and subsequent regeneration; gentle exfoliation with a soft washcloth can help, but avoid harsh scrubbing.
-
Is a follow-up visit necessary after completing the course? Dermatologists usually schedule a review 4-6 weeks post-treatment to assess clearance and decide on any further management.
