Newest Version Of The Pill May Cause Blood Clots
January 02, 2008
The latest generation of birth control pills, which were introduced in the 1980s and early 1990s, may raise a woman's risk of blood clots even more than earlier oral contraceptives. Danish investigators tracked hospital admissions for venous thromboembolism, a group of disorders that includes pulmonary embolism (clots in the lung), and deep venous thrombosis (most often clots in large veins in the legs). The study authors found that for both men and women aged 15 to 49, the number of cases of venous thromboembolism was fairly steady from 1977 to 1988. In the period from 1989 to 1993, however, the men's rate did not change, but the hospitalization rate for women was more than 16% higher. The study gives support to the hypothesis that third generation birth control pills increase the risk of venous thromboembolism to a larger extent than second-generation birth control pills.

COMMENT: I cannot think of any reason that a woman should use birth control pills. There are always other options that are less dangerous.
