💊 Adverse Effects and Precautions

Topical application of azelaic acid may produce a transient skin irritation such as burning, stinging, pruritus, dryness, and scaling. It is usually mild and disappears on continued treatment, but in a few patients the irritation may persist, requiring reduced frequency of application or temporary suspension of treatment. There have been rare reports of hypopigmentation, rash, and photosensitivity. Azelaic acid should not be applied to the eyes, mouth, or other mucous membranes.

💊 Uses and Administration

Azelaic acid inhibits the growth of Propionibacterium
spp. and reduces keratinisation. It is used in the topical treatment of mild to moderate inflammatory acne and for the inflammatory papules and pustules of mild to moderate rosacea. It has also been tried in hyperpigmentary skin disorders such as melasma, and in malignant melanoma. In the treatment of acne azelaic acid is applied twice daily for up to 6 months as a 20% cream or 15% gel. Improvement usually occurs within four weeks. For the treatment of mild to moderate rosacea, a 15% gel should be applied to the affected area twice daily for a period of up to 12 weeks. Improvement usually occurs in 4 to 8 weeks.
