If you have acne, a healthcare provider may prescribe Azelex® (azelaic acid cream). Although it is not exactly clear how this medicine works for treating acne, it is thought to have some antibacterial and anti-inflammatory properties, and may also help to normalize hyperkeratinization (a problem with skin cells that leads to pimples and other bumps).
Available in the form of a cream, Azelex is applied to the affected areas of the skin twice daily. Although most people tolerate this medicine well, side effects can occur and may include itching, stinging, and burning. If reactions do occur, they tend to be mild and easy to treat.
