    Allergic Reaction after going off birth control
    An_249793 posted:
    I have stopped taking the pill after almost 11 years. In 3 of the 4 months since going off the pill (Karvia, generic of mircette). I have gotten hives and swelling. I have been to the ER twice and allergist several times. He has not wanted to run an allergy test because it seems very random and also suggested I have an allergy to my natural hormones. I can't seem to link any foods/new things to the reactions? is it possible that this can happen?
    Jane Harrison Hohner, RN, RNP responded:
    Dear An: Yes, there are a number of case reports in the medical literature about "allergic reactions" to hormones produced by the ovaries (estrogen/progesterone). Here is a recent example taken from the National Library of Medicine site:

    Autoimmune progesterone dermatitis: a case report.
    George R, Badawy SZ.

    Department of Obstetrics and Gynecology, Upstate Medical University, Syracuse, NY 13210, USA.

    Background. Autoimmune progesterone dermatitis is a rare cyclic premenstrual allergic reaction to progesterone produced during the luteal phase of a woman's menstrual cycle. Patients present with a variety of conditions including erythema multiforme, eczema, urticaria, angioedema, and progesterone-induced anaphylaxis. Case. Thirty-eight-year-old woman G2P2002 presents with erythema multiforme and urticarial rash one week prior to her menses starting one year after menarche. She was treated with oral contraceptive pills and the symptoms resolved. Conclusion. This is a typical case of progesterone autoimmunity. The diagnosis is based on cyclic nature of the dermatitis. This differentiates the condition from other allergies or systemic diseases with skin manifestations. Inhibition of ovulation in such cases results in decrease in progesterone secretion and prevention of symptoms.

    If there is a true progesterone allergy, your symptoms would likely be present in the two weeks prior to menses (ie after ovulation). If symptoms are present all month long then the less common estrogen "allergy" MIGHT be present. Here is a case report citation on this:

    Chronic urticaria and irregular menstrual cycle: a case report of effective therapy with oral contraception.
    Kasperska-Zaj 105c A, Zamlynski J.

    Chair and Clinical Department of Internal Diseases, Allergology and Clinical Immunology, Medical University of Silesia, Katowice, Poland.

    It has been reported that urticaria may be associated with some conditions characterized by sex hormone changes. The case presented concerns a 19-year-old patient who had severe symptoms of chronic urticaria for 3 years, concomitant with an irregular menstrual cycle and functional ovarian cysts. After a laparoscopic ovarian cystectomy the patient was treated with hormonal contraceptives. After 3 weeks the symptoms of urticaria withdrew. The patient continues to receive oral contraceptive treatment, has regular menstruation and shows no symptoms of urticaria. A diagnosis with an urticaria origin should take into consideration any changes in hormone balance as one of the possible reasons for the disease. In such cases, treatment with sex hormones may positively influence the course of the illness.
