Imiquimod (Aldara) for Warts
How It Works
Imiquimod is a form of immunotherapy. Immunotherapy triggers your
immune system to fight the virus causing the wart.
This may destroy or shrink the wart.
Imiquimod is thought to work by helping the body's immune system
fight viruses, including the human papillomavirus (HPV) that causes warts. It
also may shrink the warts.
Why It Is Used
Imiquimod has been approved for use on
genital warts and can be used for hard-to-treat
common
warts. It may be used at home after a doctor teaches you how to apply it.
How Well It Works
Whether imiquimod is an effective treatment for common warts is not
yet known. It does appear to be effective in curing genital warts.1
Side Effects
Common side effects of imiquimod include:
- Itching.
- Burning.
- Blistering.
- Scaling.
- Lightening of skin
color.
Less common possible side effects include:
- Headache.

See Drug Reference for a full list of side effects. (Drug Reference
is not available in all systems.)
What To Think About
It is not known whether imiquimod is safe to use during pregnancy
or on children younger than 12.
Wash your hands after applying imiquimod cream, because it may
cause skin irritation.
Imiquimod may be used on warts that are resistant to other
treatments. It is generally used when other treatments have failed.
Imiquimod treatment is expensive.
