Before using fluorouracil topical, tell your doctor if you:
- have ever had an allergic reaction to another form of fluorouracil topical (Carac, Efudex, Fluoroplex) or injectable fluorouracil (Adrucil, 5-FU); or
- have dihydropyrimidine dehydrogenase (DPD) enzyme deficiency.
You may not be able to use fluorouracil topical, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.
Fluorouracil topical is in the FDA pregnancy category X. This means that it is known to harm an unborn baby.

Do not use fluorouracil topical if you are pregnant or planning a pregnancy. Discuss with your doctor appropriate forms of birth control before starting treatment with fluorouracil topical.
It is not known whether fluorouracil topical passes into breast milk. Do not use fluorouracil topical without first talking to your doctor if you are breast-feeding a baby.
The safety and effectiveness of fluorouracil topical in patients younger than 18 years of age have not been established.
How should I use fluorouracil topical (Carac)?
Use fluorouracil topical exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.
Fluorouracil topical is available in a number of strengths and forms (creams and solutions). It is very important that you use the correct form and strength. Contact your doctor or pharmacist if you have questions regarding which product to use.
Clean the area where you will apply fluorouracil topical. Rinse well and dry the area with a towel and wait ten minutes before applying the medication.
Wash your hands before and immediately after applying this medication, unless it is being used to treat a hand condition.
Apply fluorouracil topical to the affected area with the finger tips or a non-metal applicator, smoothing it gently onto the affected skin. Use enough to cover the entire area with a thin film.
Fluorouracil topical should not be applied on the eyelids or in the eyes, nose, or mouth. Use caution when applying fluorouracil topical around the eyes, nose, or mouth.
Do not use fluorouracil topical on skin that is irritated, peeling, or infected or on open wounds. Wait until these conditions have fully healed before using fluorouracil topical.
Do not cover the area after applying fluorouracil topical. This could cause too much medicine to be absorbed by the body and could be harmful. If a covering is needed, ask your doctor if a porous gauze dressing may be used.
A moisturizer or sun screen may be applied 2 hours after fluorouracil topical has been applied. Do not use any other skin products including creams, lotions, medications, or cosmetics unless instructed by your doctor.
The reaction of the skin treated with fluorouracil topical may be unsightly during treatment, and sometimes, for several weeks after completion of therapy.
Store fluorouracil topical at room temperature away from moisture and heat.
