oral contraceptive (OC)

oral hormone medication for contraception. The two major sex hormones in females are estrogens and progestins. When synthetic forms of these hormones are taken, they inhibit the production of gonadotropin-releasing hormone by the hypothalamus; the pituitary therefore does not secrete gonadotropins to stimulate follicular maturation and ovulation. Depending on the formulation, cyclical changes in the uterus, vagina, and breasts may be similar to a normal menstrual cycle. Progestin-only oral contraceptives generally do not block ovulation. Instead they cause the cervical mucus to remain thick, which prevents the entry of sperm into the uterus and fallopian tubes. Seasonale, an extended-cycle method of contraception with menstrual periods every three months, was recently approved by the FDA. Contraindications to the oral contraceptives include pregnancy, diabetes mellitus, liver disease, hyperlipidemia, thrombotic complications, coronary artery disease, and sickle cell disease. Patients with depression and migraine headaches and those who are heavy cigarette smokers need to be followed up more often. The pregnancy rate when oral contraceptives are used correctly is less than 0.2% a year. See also contraception.

or·al con·tra·cep·tive

(OC) (ōr'ăl kon'tră-sep'tiv)
A medication taken by mouth designed to prevent conception.

oral contraceptive

A drug or combination of drugs taken by mouth for the purpose of preventing pregnancy. Most oral contraceptives must be taken by women. They contain oestrogens and/or PROGESTOGENS and act by preventing the ovaries from producing eggs (ova). They also have some effect in making the lining of the womb less suitable for implantation of the ovum and may make the mucus in the canal of the cervix less easily passable by sperms. Oral contraceptives are second after sterilization in effectiveness in avoiding pregnancy. Risk attributable to oral contraceptives is very small among non-smokers but there are certain categories, notably women with thrombophilia from genetic mutations, in which the risk is slightly increased. The increased risk of breast cancer has been greatly exaggerated. It amounts to no more than roughly 1 additional case per 20,000 women. Also known as ‘the pill’. See also CONTRACEPTION.
