FAQs
What does a progesterone rash look like?
A progesterone rash typically appears as itchy, red papules or hives-like wheals that usually flare 3–4 days before a menstrual period or after progesterone hormone treatments like IVF shots. Lesions may be raised, red, and without scaling.
When does autoimmune progesterone dermatitis usually occur?
It usually occurs during the luteal phase of the menstrual cycle, about 3–10 days before menstruation, early pregnancy, or after progesterone hormone therapy such as IVF treatments.
How can I differentiate progesterone rash from other skin conditions?
Key differences include its cyclic timing matching hormonal events, the appearance of papular or urticarial lesions without eczema scaling, and association with progesterone exposure or therapy. New soaps or allergens are usually ruled out.
Is autoimmune progesterone dermatitis treatable?
Yes, treatment includes topical corticosteroids, antihistamines, hormonal modulation, desensitization protocols, and in severe cases, systemic steroids or immune therapy under doctor supervision.
Can progesterone rash affect pregnancy or fertility?
Progesterone rash (APD) itself does not impair fertility, and many women conceive successfully with proper management. Treatment during pregnancy focuses on safe topical steroids and antihistamines under medical guidance.
