Azelaic acid is a prescription medication used to control the symptoms of mild or moderate acne, as well as the skin disease called rosacea. It is also known as lepargylic acid or heptanedicarboxylic acid. While products that contain azelaic acid are generally effective, proper use requires adherence to certain basic treatment guidelines.
The Basics
Azelaic acid belongs to a group of medications called dicarboxylic acids, according to the U.S. National Library of Medicine's Medline Plus. In acne treatment, it achieves its effects by limiting production of the skin protein keratin and killing off harmful bacteria. Doctors do not currently understand the mechanisms that make azelaic acid effect in combating rosacea. If you receive azelaic acid for acne, it will likely come in the form of a cream product called Azelex. If you receive the medication for rosacea, it will probably come in the form of a gel product called Finacea or Finacea Plus.
Initial Steps
Prior to using an azelaic acid-containing product, you should tell your doctor if you have any known medical problems or allergies, including previous reactions to azelaic acid, according to the Mayo Clinic. You should also tell your doctor about any medications you currently take, as well as any dietary supplements, herbal products or vitamins.If you are pregnant, be aware that doctors do not know if azelaic acid use poses any risks to fetal development. Older individuals should also note the fact that the specific effects of azelaic acid have not been studied in elderly populations.
Skin Application
You will typically apply an azelaic acid-based gel or cream to your affected skin twice daily, Medline Plus reports. Before application, you should wash your affected skin with a nonalcoholic cleanser. After drying your skin, apply a thin layer of cream or gel and massage it into your skin until it is fully absorbed. Avoid any contact with your mouth, eyes or mucous membranes during treatment, and wash your hands thoroughly when you are done. After treatment, do not place restrictive coverings, such as wrappings, bandages or dressings, on the treatment site.
Side Effects
The Mayo Clinic lists relatively common potential side effects of azelaic acid that include skin peeling, redness, itching, burning, dryness, stinging or tingling. In some cases, these effects may diminish or disappear during the course of treatment. If you are bothered by any particular side effect, contact your doctor for advice. If you develop a rash while using azelaic acid, talk to your doctor immediately. In rare circumstances, use of azelaic acid can cause a lightening or whitening of skin in individuals with relatively dark complexions.
Considerations
If you use azelaic acid for rosacea, you should avoid any food or beverage that triggers blushing or flushing, Medline Plus notes. Depending on your particular circumstances, examples of these substances may include spicy food, alcohol or any hot liquid. Use of azelaic acid-containing products may not sufficiently ease your symptoms of acne or rosacea for a period of a month or longer. If this is the case, make sure that you keep applying the medication as prescribed during initial treatment stages.
