Efudex (Fluorouracil) Cream for Actinic Keratosis

Efudex contains fluorouracil, a topical antimetabolite used for actinic keratoses and selected superficial basal cell carcinomas when prescribed by a dermatologist. Fluorouracil interferes with DNA synthesis in rapidly dividing abnormal cells. The expected treatment reaction can be intense, so follow the dermatologist’s plan closely.

• Use: dermatologist-directed treatment of selected precancerous or superficial cancerous skin lesions.
• Class: topical fluoropyrimidine antimetabolite.
• Application: a thin layer to the exact treatment area as prescribed.
• Critical warning: do not use during pregnancy.

How should Efudex be applied?

Apply to clean, dry skin at the frequency and duration prescribed. Avoid eyes, lips, nostrils, mucous membranes, open wounds, and healthy skin unless directed. Wash hands thoroughly after use. Confirm the prescribed strength before you buy Efudex 5% or buy Efudex 2%; do not extend treatment or treat a new area without dermatology advice.

What skin reaction is expected with Efudex?

Redness, burning, itching, dryness, scaling, crusting, tenderness, and erosion can occur as abnormal cells react to treatment. The treating clinician should explain the expected severity and timing. Contact the clinic promptly for severe pain, extensive blistering, ulceration, swelling, fever, spreading rash, or suspected infection. Protect treated skin from sunlight with clothing and clinician-approved sun protection.

Who should avoid Efudex?

Do not use with a known fluorouracil allergy, during pregnancy, or when a clinician identifies dihydropyrimidine dehydrogenase deficiency risk. Breastfeeding, active skin infection, and use of other irritating topical products require individual advice. Accidental ingestion needs urgent medical attention.

What should I know before ordering Efudex?

Use the current dermatologist prescription and an authorized pharmacy before you buy Efudex. Efudex price varies by cream strength, tube size, and dispensing rules. When comparing Efudex price, prioritize the correct diagnosis, treatment area, expiry date, and follow-up plan. A low Efudex price does not verify safe supply; do not decide to buy Efudex from an unverified seller.

Store the closed tube as labeled, away from heat and children. This page is educational and does not replace dermatology care.

Follow-up is important because the appearance of treated skin does not by itself confirm complete clearance. The dermatologist may examine the area after healing and decide whether another treatment, biopsy, or sun-damage prevention plan is needed. Ask before using cosmetics, medicated creams, or abrasive products on the treatment site today.
