Do not use Efudex if you are pregnant. Expect redness, soreness and crusting on treated skin. Protect the area from the sun, and keep the cream away from your eyes and mouth.
How your clinician sets your plan
Your clinician decides which area to treat, how often to apply the cream and for how long. The plan depends on the area, your skin and how it reacts.
Considerations include
- Number and location of spots
- Skin sensitivity and past reactions
- Past sun-damage treatments and results
- Your other medicines and conditions
- Pregnancy plans and breastfeeding
How Efudex works
Efudex targets sun-damaged cells
Efudex contains 5-fluorouracil, a medicine that blocks the building of DNA. Sun-damaged cells grow fast, so they are hit harder than healthy cells.
The skin reacts as the damaged cells die. After treatment, new and healthier skin grows back.

Start my assessmentYour clinician decides if Efudex is right for you. You share your history and photos, and a Canadian-licensed medical professional reviews them. If Efudex is prescribed, a Canadian pharmacy fills it.
Efudex contains 5-fluorouracil, which blocks the building of DNA in fast-growing cells. Sun-damaged cells grow fast, so they are affected most. Healthy skin then grows back.
A course lasts several weeks. Redness and soreness build over that time, and the skin heals in the weeks after. Your clinician tells you when to stop.
Redness, soreness, crusting and peeling are expected. Burning, itch and sun sensitivity are common. Call your Care Team if pain is severe or if the skin looks infected.
Do not use it in pregnancy. Do not use it if you are allergic to it, or if you know you lack the DPD enzyme. Tell your clinician about all your medicines.
Imiquimod is a cream with a different action. Actikerall, a mix of 5-FU and salicylic acid, suits thicker spots. In-person options include freezing the spot. Your clinician helps you choose.
Use a gentle moisturizer if your clinician allows it. Do not put other active skin products on the area. Tell your clinician about every product you use.
No. Do not use it in pregnancy, because it can harm a baby. Tell your clinician if you plan pregnancy or breastfeed. Your clinician can suggest other care.
Each consultation costs CA$175. Your pharmacy charges separately for medication. Ask your insurer whether your plan covers the prescribed treatment.
Efudex is the brand name in Canada. Ask your pharmacist if another version is available. Your clinician writes the prescription for the product that fits you.
Your clinician reviews your progress before a refill. Your Care Team sends the renewal to your pharmacy when your clinician approves it. Write to us before you run out, so that your treatment does not stop.
See a doctor if a spot bleeds, grows fast, hurts or does not heal. These can be signs of skin cancer. Your clinician may refer you for an in-person check.
Simple pricing for your skin care.
Medication costs are separate. Ask your insurer whether your plan reimburses online consultations.
