| classification | Keratolytic, Anti-inflammatory, Comedolytic |
| pharmacokinetics | Azelaic acid is a topical agent. It is primarily absorbed locally and is not systemically absorbed to a significant extent. The exact pharmacokinetics are not well characterized in terms of absorption and metabolism at the skin level. |
| suggested dosage | A common regimen is 10-20% azelaic acid cream or gel applied once or twice daily, as directed by a dermatologist. Specific dosage and frequency are tailored to the patient's condition and response. |
| indications | Azelaic acid is primarily used in the treatment of moderate acne vulgaris, including inflammatory lesions like papules, pustules, and nodules. It is also used for the treatment of rosacea and melasma (hyperpigmentation). |
| safety in pregnancy | Limited data is available on azelaic acid's safety during pregnancy. Consult a dermatologist or physician for guidance on use during pregnancy, weighing the potential benefits against possible risks. |
| safety in breastfeeding | There are no reports of significant azelaic acid passage into breast milk, but limited data exists. Consult a dermatologist or physician for guidance on use during breastfeeding, weighing the potential benefits against possible risks. |

| warnings and precautions | | 1 | Azelaic acid may cause skin irritation or discoloration in some individuals, particularly at higher concentrations or with prolonged use. Careful monitoring is important. | | 2 | Patch testing may be recommended before widespread application to identify potential allergic reactions | | 3 | Avoid using other topical skin products (e.g., harsh cleansers, peels) on the treated areas until the irritation subsides. | | 4 | Do not apply azelaic acid to broken or damaged skin. | | 5 | May cause a temporary lightening or darkening of skin.
