Prevents ovulation by suppressing FSH and LH;
monophasic:
estrogen/progestin (fixed dose) used during a 21-day cycle; ovulation is inhibited by suppression of FSH and LH; thickness of cervical mucus and endometrial lining prevents pregnancy;
biphasic:
ovulation is inhibited by suppression of FSH and LH; alteration of cervical mucus,
endometrial lining prevents pregnancy;
triphasic:
ovulation is inhibited by suppression of FSH and LH; change of cervical mucus, endometrial lining prevents pregnancy; variable doses of estrogen/progestin combinations may be similar to natural hormonal fluctuations;
extended cycle:
estrogen/progestin continuous for 84 days, off for 7 days, results in 4 menstrual periods/yr;
progressive estrogen:
constant progestin with 3 progressive doses of estrogen;
progestin-only pill, implant, intrauterine:
change of cervical mucus and endometrial lining prevents pregnancy; ovulation may be suppressed
To prevent pregnancy, regulation of menstrual cycle, treatment of acne in women >14 yr for whom other treatment has failed, emergency contraception;
injection:
inhibits gonadotropin secretion, ovulation, follicular maturation;
emergency:
inhibits ovulation and fertilization, decreases transport of sperm and egg from fallopian tube to uterus;
vaginal ring, transdermal:
inhibits ovulation, prevents sperm entry into uterus;
antiacne:
may decrease sex hormone binding globulin, results in decreased testosterone
Pregnancy (X), breastfeeding, women ≥40 yr, reproductive cancer, thrombophlebitis, MI, hepatic tumors, hepatic disease, CAD, CVA, breast cancer, jaundice, stroke, vaginal bleeding
Precautions:
Depression, hypertension, renal disease, seizure disorders, lupus erythematosus, rheumatic disease, migraine headache, amenorrhea, irregular menses, gallbladder disease, diabetes mellitus, heavy smoking, acute mononucleosis, sickle cell disease
