Imiquimod Cream 5%

What is Imiquimod?

Imiquimod is a topical cream that is used to treat external genital warts in people over the age of 12. Imiquimod can be used to fight the warts, but it doesn’t cure the underlying virus that causes the warts. You apply Imiquimod cream at night and it helps to encourage the immune cells to attack the warts.

How does Imiquimod work?

Imiquimod works by stimulating the immune system to identify abnormal cells. This produces inflammation and encourages the immune system to combat genital warts.

Which ingredients can cause an allergic reaction?

Unless you are specifically allergic to one of the active or inactive ingredients in the medication, none of the ingredients are not linked to cases of severe allergic reaction. You might notice a burning sensation when applying the cream to the affected area as it contains alcohol. However, after a few days, you won’t experience this anymore as your skin will get accustomed to the medication.
