Azelaic acid comes as a gel, foam, and a cream to apply to the skin. It is usually applied twice a day, in the morning and the evening. To help you remember to use azelaic acid, use it at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use azelaic acid exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Be careful not to get azelaic acid in your eyes or mouth. If you do get azelaic acid in your eyes, wash with plenty of water and call your doctor if your eyes are irritated.
Azelaic acid foam is flammable. Stay away from open fire, flames, and do not smoke while you are applying azelaic acid foam, and for a short time afterwards.
To use the gel, foam, or cream, follow these steps:
- Wash the affected skin with water and a mild soap or soapless cleansing lotion and pat dry with a soft towel. Ask your doctor to recommend a cleanser, and avoid alcoholic cleansers, tinctures, abrasives, astringents, and peeling agents, especially if you have rosacea.
- Shake the azelaic acid foam well before use.
- Apply a thin layer of gel, or cream to the affected skin. Gently and thoroughly massage it into the skin. Apply a thin layer of foam to the entire face including cheeks, chin, forehead, and nose.
- Do not cover the affected area with any bandages, dressings, or wrappings.
- You may apply make-up to your face after the medication is dry.
- Wash your hands with soap and water after you finish handling the medication.
