What special precautions should I follow?

• Use of COCs also increases the risk of arterial thromboses such as strokes and myocardial infarctions, especially in women with other risk factors for these events. Stop LoSeasonique if a thrombotic event occurs. Stop LoSeasonique at least 4 weeks before and through 2 weeks after major surgery. Start LoSeasonique no earlier than 4 weeks after delivery, in women who are not breastfeeding.
• Discontinue LoSeasonique if jaundice occurs. Steroid hormones may be poorly metabolized in patients with impaired liver function.
• An increase in blood pressure has been reported in women taking COCs, and this increase is more likely in older women and with extended duration of use. Do not prescribe LoSeasonique for women with uncontrolled hypertension or hypertension with vascular disease.
• COCs may decrease glucose tolerance in a dose-related fashion. Monitor prediabetic and diabetic women taking LoSeasonique. Consider an alternate contraceptive method for women with uncontrolled dyslipidemias.
• If a woman taking COCs develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue COCs if indicated.
• Unscheduled (breakthrough) bleeding and spotting sometimes occur in patients on COCs, especially during the first 3 months of use. Evaluate irregular bleeding or amenorrhea.
• Women who currently have or have had breast cancer should not use COCs because breast cancer may be hormonally sensitive.
• The use of COCs may change the results of some laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins. Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentrations of thyroid binding globulin increase with use of COCs.
• A woman who is taking COCs should have a yearly visit with her healthcare provider for a blood pressure check and for other indicated healthcare.
