What Is Fluorouracil?

Fluorouracil (5-fluorouracil, 5-FU) is a prescription topical medication used to manage actinic keratosis and certain superficial skin cancers. It works by interfering with DNA and RNA synthesis in rapidly dividing abnormal cells, causing them to die off. With the right application schedule and ongoing monitoring, fluorouracil helps clear precancerous lesions and reduce the risk of progression to squamous cell carcinoma.

Is Online Fluorouracil Treatment Right for You?

Doctronic can help adults who are currently being treated for actinic keratosis with topical fluorouracil and need a prescription refill. To qualify, you should have an established diagnosis and prior use of fluorouracil cream or solution without serious adverse reactions.

Because fluorouracil affects skin cell turnover and can cause local reactions, our physicians will review your dermatologic history, current lesion status, and any prior treatment responses to ensure continued safe and appropriate use.

Frequently asked questions

Fluorouracil cream is most commonly prescribed to treat actinic keratosis, which are rough, scaly patches on the skin caused by years of sun exposure. It is also used for certain superficial forms of basal cell carcinoma. The medication works by disrupting the growth of abnormal skin cells.

Fluorouracil is typically applied once or twice daily to the affected skin area using a fingertip or applicator, then washed off after a prescribed period. Your physician will specify the exact frequency and duration, which usually ranges from two to four weeks depending on the condition being treated.

It is normal to experience redness, swelling, burning, crusting, and peeling of the treated skin. These reactions indicate the medication is working. Severe pain, open sores, or signs of infection should be reported to your physician promptly.

Most treatment courses for actinic keratosis last between two and four weeks. Your physician may adjust the duration based on how your skin responds. Do not stop treatment early without consulting your provider, as incomplete courses may reduce effectiveness.

Yes, topical fluorouracil is commonly used on the face, scalp, and other sun-exposed areas where actinic keratoses frequently develop. Avoid contact with the eyes, nostrils, and mouth. If accidental contact occurs, rinse thoroughly with water.

Certain medications, including other chemotherapy agents and some antivirals, can interact with fluorouracil. You should also inform your physician if you have a dihydropyrimidine dehydrogenase (DPD) enzyme deficiency, as this can cause severe toxicity. Always provide a complete medication list when requesting a refill.
