What Birth Control is Best for Me If I’m Allergic to Estrogen?

If you are allergic to estrogen, you should use a progestin-only or barrier method of birth control. Estrogen is a commonly used hormone in birth control medication; though for someone women, it can cause uncomfortable side effects, and for others, an allergic reaction. You may also benefit from progestin-only birth control if:

  • You are over 35 and smoke
  • You have high blood pressure
  • You have had a history of blood clots
  • You are breastfeeding

Types of progestin-only birth control

There are multiple types of progestin-only birth control methods you can use if you have an allergy to estrogen:

  • Mini pills: Mini pills are progestin-only birth control pills that are very effective when taken at the same time every day.
  • Depo-Provera: The depo shot is an injection that slowly releases progestin into the body to provide pregnancy protection for up to 14 weeks.
  • Mirena IUD: Mirena is an intrauterine device that your healthcare professional will insert into your uterus, from where it will release a small amount of progestin. It works by preventing pregnancy through blocking the path up the fallopian tubes and by releasing a hormone that reduces your chance of ovulation and conception as well. The Mirena IUD can provide protection for up to five years when left in place.
  • Nexplanon Implant: The Nexplanon is a subdermal implant that releases progestin over time and can provide up to three years of pregnancy protection. It will be inserted into the arm in a simple procedure that can be performed in a health care facility.

Barrier methods

If you are allergic to estrogen, you can also use barrier methods to prevent pregnancy. The most common forms of barrier protection include:

  • Condoms
  • Diaphragms
  • Cervical caps
