New study confirms that some contraceptive pills riskier than others

New study confirms that some contraceptive pills riskier than others - Telegraph: Women taking so-called 'third generation' contraceptive pills, those developed in the 1980s, are up to three times more likely to suffer a blood clot than those who use older varieties, according to new research based on British and American records. With no real other advantages of the newer drug, scientists said it would be 'prudent' to make the older pills the 'first line choice.' Scientists say doctors should prescribe pills that contain the hormone levonorgestrel, rather than drospirenone.
