Higher risk for: smokers over 35 (thromboembolism), those with liver disease, concurrent CYP3A4 inducers (may reduce contraceptive efficacy), history of blood clots, migraines with aura, or obesity.
Some medications can reduce contraceptive effectiveness. Monitor when combining Combined Oral Contraceptives with Astragalus. Watch for: breakthrough bleeding or spotting (may signal reduced contraceptive levels), missed periods, mood changes, headaches, nausea, or changes in blood clotting symptoms. Use backup contraception if advised by your prescriber. When to seek emergency help: Severe leg pain or swelling (possible blood clot), sudden severe headache, chest pain, shortness of breath, vision changes, or signs of stroke (facial drooping, arm weakness, speech difficulty). Report all medications to your gynecologist.
