How to use
- 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.
- 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.
- 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.
First 8 weeks. Photograph your face in the same light at the start and at 8 weeks; count papules and pustules rather than judging redness by eye. Keep a trigger diary (heat, alcohol, spicy food, sun, stress) and use SPF 50+ daily. Stinging in the first 2 weeks is expected; apply to fully dry skin and follow with a bland moisturiser.
Ongoing. Stop and ask for review if there is no improvement after 2 months, or sooner for a spreading rash, swelling or worse asthma control. Avoid alcohol-based toners, scrubs and other acids; they undo the barrier work. Rosacea is a long-term condition; maintenance with azelaic acid is reviewed every 3 to 6 months.

Doctor review
Your doctor may switch to the compounded ivermectin spot formula, or discuss oral doxycycline.
Weeks 1-12Matching treatment to your pattern
Spots dominate
Ivermectin-based formula
High-certainty evidence for papules and pustules; once daily for 12 weeks.
Redness dominates
Redness formula or vasoconstrictor
Inflammatory redness may respond to the compounded cream; purely vascular flushing needs trigger control or a vasoconstrictor product.

Dose schedule
| Dose | When | Note |
|---|---|---|
| 15% gel, twice daily | Weeks 1-2 | Stinging is common on rosacea skin; apply to fully dry skin and use less product. |
| 15% gel, twice daily | Weeks 3-8 | Papules and pustules reduce gradually; photo review at 8 weeks. |
| 15% gel, once or twice daily | Weeks 9-12 and on | Judged at 12 weeks; azelaic acid is an evidence-based maintenance option. |
How it compares
| Rosacea treatments compared | How it works | Best suited for | How often | Judged at | Product type |
|---|---|---|---|---|---|
| Azelaic acid 15% | Reduces inflammation and follicular signals behind papules and pustules | Papulopustular rosacea; first-line; sensitive skin | Twice daily | 12 weeks | EU-authorised medicine |
| Compounded redness formula | Metronidazole and azelaic acid calm inflammation; niacinamide and allantoin repair the barrier | Persistent background redness with a mild inflammatory component | Once daily | 12 weeks | Pharmacy-compounded to prescription |
| Compounded spot formula | Ivermectin acts on Demodex and inflammation; metronidazole adds anti-inflammatory effect | Moderate papules and pustules, or after azelaic acid alone is not enough | Once daily | 12 weeks | Pharmacy-compounded to prescription |
Evidence certainty from van Zuuren 2019 (BJD): high for azelaic acid and ivermectin, moderate for metronidazole, for papules and pustules. Compounded combinations have not been trialled as products.
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.
Do not use 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
When to contact your doctor
- 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.
