What Is Azelaic Acid?

Possible Side Effects

Azelaic acid appears to cause several possible side effects. Skin changes may be the most common. One example seems to be a tingling or burning sensation after application. Patients may deal with itchy, red, or dry skin too. Skin peeling appears to be another possible side effect. Less common side effects seem to include blisters, swelling, skin flaking, severe redness, and soreness. Patients may want to keep their doctor informed about all of these side effects. However, they may need to tell their doctor immediately if this medication causes their skin to lighten where they applied it. A reaction such as this may require them to stop using azelaic acid.

Some patients may be allergic to azelaic acid. If this is the case, possible symptoms seem to include difficulty breathing and hives. Tongue, lip, or face swelling may also occur. Emergency care appears to be necessary if individuals experience these symptoms. Rare side effects may include a hoarse voice, tightness in the chest, an elevated heart rate, fever, joint pain, and eye swelling. Patients may need their doctor to evaluate them if they see these effects.
