Azelaic acid rosacea guide
How to use azelaic acid 15% gel for adult papulopustular rosacea while reducing irritation and common triggers.
How to use
- 01
Step 1
What it is and how it works
Azelaic acid reduces inflammation involved in the papules and pustules of rosacea. This guide covers the prescribed 150 mg/g cutaneous gel; it does not treat an eye flare or a changing skin lesion.

Step 2
Apply it as prescribed
After gentle cleansing and drying, apply a thin layer morning and evening. About 0.5 g, or a 2.5 cm strip, is enough for the whole face. Avoid the eyes, mouth, mucosa, broken skin and occlusive dressings, then wash your hands.

Step 3
Skin care and interactions
Use a gentle cleanser, moisturiser and daily broad-spectrum sunscreen. Avoid alcohol-based cleansers, astringents, abrasives and peels. Do not apply another facial medicine at the same time unless your prescriber has checked the combination, and note personal triggers such as heat, alcohol or spicy food.
Dose schedule
- 01
Step 1
Timing and review
Use twice daily as prescribed. If irritation develops, the clinician may advise once-daily use or a short pause. Review tolerance at 2–4 weeks and response at 2 months; stop and request assessment if rosacea worsens or has not improved by then.

Step 2
If you miss an application
Apply it when you remember unless the next scheduled application is near. In that case, skip it and continue as usual. Do not apply extra product to make up for it.
Side effects
Local irritation
Mild redness, dryness, stinging or peeling can occur, especially at the start. Use a gentle moisturiser and follow the prescribed adjustment plan. Stop and seek advice if the reaction is marked or persistent.
Sensitivity or asthma symptoms
A rash or colour change can occur, and asthma has rarely worsened. Stop using the gel and seek advice for a spreading rash, wheeze or a clear change in asthma control.
04 · Do not use if
Do not use this treatment if
- You are allergic to azelaic acid or an ingredient in the gel
- The skin is broken, sunburnt, severely irritated or affected by active eczema
- You are pregnant or breastfeeding and your clinician has not made an individual decision
05 · When to contact your doctor
Contact your doctor if
- Facial swelling, breathing difficulty, widespread blistering, eye pain, light sensitivity or altered vision — seek urgent medical care
- Rosacea is worse or has not improved after 2 months, or new eye symptoms appear
- Wheezing, shortness of breath or worse asthma control after starting the gel
Storage
Keep the tube tightly closed in its original package, out of children's reach. Follow the temperature and expiry instructions on the label and do not use the product after it expires.
What to expect
Papules and pustules should improve gradually rather than overnight. Assess the result at 2 months. Daily gentle skin care and trigger management remain part of treatment even when the medicine is working.
