Autoimmune progesterone dermatitis (APD)




A reaction to the progesterone hormone produced during the menstrual cycle, causing various eruptions to form on the skin.

Common Symptoms

Hives (urticaria), itchy inflammation from eczema, swelling under the skin from angioedema, and anaphylaxis (a life-threatening allergic reaction) may also occur.

Coexisting Diseases and Conditions

Atopic dermatitis (eczema) or erythema multiforme.

Risk Factors

APD most commonly occurs in females in their 30’s and risk increases with use of progesterone-only oral contraceptives.
