This medicine works by disrupting the progress of cancerous cells. Cancerous cells are quickly growing and dividing to form "daughter" cells and the 5-fluoruracil prevents the cancerous cells from be able to form offspring cells.

The two existing formulations, known as efudex and carac, are formulated at different concentrations and are used at different frequencies to achieve similar outcomes. When using this cream, the section treated turns intense red and the skin actually looks worse before it clears up. This is an important aspect as the skin is clearly irritated during use.

Throw away any unused medicine after the expiration date.

Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first.
