Answer

High-dose estrogen therapy is another risk factor. Case-controlled and cohort studies based on clinical signs and symptoms of thrombosis suggest that by taking high-estrogen oral contraceptives, a woman may increase her risk of thrombosis by a factor of 3-12 times, though the absolute risk remains low. Newer low-dose oral contraceptives are associated with a much lower risk of thrombophlebitis, though the absolute risk has not been well quantified. [7]
