Treatment with Efudex

Efudex may be used over a short course, usually resulting in an intense reaction or over a longer period of several months to lessen the degree of reaction. You may wish to discuss these options at the time of your visit.

Not all actinic keratoses are easily seen so you may experience a local reaction to the medication in areas you did not expect. As a result, it is impossible for us to predict the exact nature or the degree of reaction you will experience.

You will probably have a very obvious red rash that may raise questions if your employment requires you to meet the public or handle food in public.

Hot weather and sweating will contribute to the over-all discomfort of Efudex treatment.

The most common side effects are: redness, itching, burning, tenderness, scaling, crusting, and/or swelling. If any of these become severe or you notice any drainage that is green, yellow, or appears to be pus, please call the office.

The side effects of Efudex are generally considered to be topical only. The use of Efudex should not make you sick in the sense of nausea, vomiting, or cause you to experience aches and pains.

It is expected that normal skin will replace the keratoses but healing can take 1-2 months depending on the severity of your reaction which varies greatly between patients.

If you are worried by the appearance of the treated site, or if you have any questions or concerns, please call the office.
