Table of Contents


Vaniqa (Eflornithine) is used to slow down the growth of unwanted hair on the face and under the chin in women. It should not be used for hair on other parts of the body.

It works by blocking a naturally-occurring enzyme that is needed for hair growth in the skin. Blocking this enzyme slows hair growth and may also make the hair finer and lighter. Vaniqa does not cause hair to fall out or remove hair.

This drug is not for use in children younger than 12 years.
