Purpose of estrogen in COC
-Inhibits FSH & ovulation
-Increases aldosterone = increased sodium/water retention
-Increases sex hormone binding globulin = clears up hormone-related acne & unwanted facial hair
Estrogen ADR in COC
N/V
Bloating, edema
Irritability
Cyclic weight gain, headache
HTN
Breast fullness/tenderness
Progestational progestins
prevent ovulation & lessen bleeding
high activity: desogestrel, etonogestrel, levonorgestrel
Androgenic progestins
Contributes to acne, hirsutism
high activity: levonorgesterl, norgestrel
Antiestogenic progestins
Contributes to androgenic side effects (hair loss, hirsutism, acne, oily skin)
High activity: norethindrone, ethynodiol diacetate
Progestin action in COCs
Thicken cervical mucus - prevent sperm
Endometrial atrophy (thins uterus linig)
prevent ovulation
Progestin ADRs in COCs
HA
Increased appetite, weight gain
Depression, fatigue
Change in libido
Androgenic: hair loss, hirsutism, acne, oily skin
Management of breakthrough bleeding
Try x 3 months
Late in cycle = choose higher progestin activity
Otherwise choose higher estrogen/progestin activity
Acne management from COC
Choose lower androgenic activity progestin
Serious adverse effects from COC
ACHES
A: abdominal pain = liver, gallbladder issue
C: chest pain, SOB, coughing up blood = MI, PE
H: headache = stroke, blood clot
E: eye problems = optic neuritis, stroke, clots
S: severe leg pain = DVT
Drugs that may decrease effectiveness of COC
-HIV drugs (NRTIs, maraviroc, INSTI, NNRTI, PI)
-Antiepileptics
-Rifampin/rifabutin
-Tetracycline, minocycline, erythromycin, pcn, cephalosporins = back up for abx therapy + 7 days after
