Are there any side effects of azelaic acid topical gel or cream?

While using Azelex or Finacea which contain azelaic acid that is applied topically, you may experience dryness, itching, burning, tingling, or stinging on the face. These are all common side effects that should not be a cause for concern, unless they become persistent or grow worse over time. Contact your doctor if this occurs, or if your skin begins to peel or change color, or your face becomes irritated and inflamed. If you develop signs of an allergic reaction (such as a rash or hives, swelling, or chest tightness and difficulty breathing), get emergency medical assistance.
