Birth control pill in the context of Progestin

Oral contraceptives, abbreviated OCPs, also known as birth control pills, are medications taken by mouth for the purpose of birth control. The introduction of the birth control pill ("the Pill") in 1960 revolutionized the options for contraception, sparking vibrant discussion in the scientific and social science literature and the media. Much attention focused on issues of women's rights, including ethics and personal choice. But these medications also introduced new questions about risk.

Long-acting reversible contraceptives (LARC) are methods of birth control that provide effective contraception for an extended period without requiring user action. They include hormonal and non-hormonal intrauterine devices (IUDs) and subdermal hormonal contraceptive implants. They are the most effective reversible methods of contraception because their efficacy is not reliant on patient compliance. The failure rates of IUDs and implants is less than 1% per year.

LARCs are often recommended to people seeking convenient and cost effective contraception. In one study, LARC users saved thousands of dollars over a five-year period compared to those who buy condoms and birth control pills. LARCs can generally be safely and effectively used by people of any body weight, adolescents, and people who have not yet had children.

Norgestrel, sold under the brand name Opill among others, is a progestin which is used in birth control pills. It is often combined with the estrogen ethinylestradiol, marketed as Ovral. It is also used in menopausal hormone therapy. It is taken by mouth.

Side effects of norgestrel include menstrual irregularities, headaches, nausea, and breast tenderness. The most common side effects of the norgestrel include irregular bleeding, headaches, dizziness, nausea, increased appetite, abdominal pain, cramps, or bloating. Norgestrel is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has weak androgenic activity and no other important hormonal activity.

G. D. Searle & Company (often referred to as Searle) was an American pharmaceutical company, now owned by Pfizer. Searle is most notable for having developed the first female birth control pill, and the artificial sweetener NutraSweet. Searle also developed the drug Lomotil, an antidiarrheal medication. One notable alumnus of Searle was Donald Rumsfeld, the Secretary of Defense for George W. Bush in the 2000s. Prior to its 1985 merger with Monsanto, Searle was a company mainly focusing on life sciences, specifically pharmaceuticals, agriculture, and animal health.

Norethisterone, also known as norethindrone and sold under the brand name Norlutin among others, is a progestin medication used in birth control pills, menopausal hormone therapy, and for the treatment of gynecological disorders. The medication is available in both low-dose and high-dose formulations and both alone and in combination with an estrogen. It is used by mouth or, as norethisterone enanthate, by injection into muscle.

Side effects of norethisterone include menstrual irregularities, headaches, nausea, breast tenderness, mood changes, acne, increased hair growth. Norethisterone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone. It has weak androgenic and estrogenic activity, mostly at high dosages, and no other important hormonal activity.
