Junel®, Loestrin®, Microgestin®, Tri-Legest®: Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke.Femhrt®: Estrogen alone or with a progestin should not be used for the prevention of cardiovascular disease or dementia. Increased risks of stroke, DVT, pulmonary embolism, myocardial infarction, and invasive breast cancer have been reported with estrogen plus progestin therapy. Increased risks of stroke and DVT have been reported with estrogen-alone therapy, along with increased risk for endometrial cancer in a woman with a uterus who uses unopposed estrogens. An increased risk of probable dementia in postmenopausal women aged 65 and older has been reported with estrogen alone and with estrogen plus progestin therapy. Risks should be assumed to be similar for other doses, combinations, and dosage forms of estrogens and progestins. Estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration possible.
