Seasonique and Breastfeeding

If you are taking Seasonique and breastfeeding, you should know that the contraceptive can decrease the production and quality of breast milk. Studies have shown that the hormones in birth control pills do pass through breast milk in low amounts. Although these amounts are not likely to cause any serious problems, if you are thinking about using Seasonique while breastfeeding, talk to your healthcare provider first.

Is Seasonique Safe During Breastfeeding?

Seasonique™ (levonorgestrel/ethinyl estradiol) is a prescription birth control pill. It is classified as a combined oral contraceptive because it contains both a progestin and an estrogen. Although they are effective at preventing pregnancy, combined oral contraceptives (including Seasonique) are not recommended for breastfeeding women.
(Amethia™ and Camrese™ are generic versions of Seasonique. The information in this article also applies to Amethia and Camrese as well.)

Seasonique and Breastfeeding: What Does the Research Say?

Studies have shown that the hormones in birth control pills pass through breast milk in low amounts. These tiny amounts are probably too low to cause any significant problems in breastfeeding infants. However, there have been cases of problems (such as breast enlargement and jaundice) in babies whose mothers took certain types of combined oral contraceptives while breastfeeding.
More importantly, combined contraceptives may decrease the production and quality of breast milk. For this reason, healthcare providers almost always recommend progestin-only oral contraceptives (also known as "mini-pills") instead of combined contraceptives for women who are breastfeeding. However, progestin-only contraceptive pills are usually less effective than combined contraceptives. As soon as you stop breastfeeding, it may be a good idea to ask your healthcare provider about switching to a combined contraceptive product such as Seasonique.
