Birth control pills Yaz, Yasmin and the generic Ocella have a unique ingredient called drospirenone, a synthetic progestin, which is not found in other birth control pills. Drospirenone has been associated with a number of severe side effects. Reported serious side effects include blood clots, as two recent epidemiological studies of pills containing drospirenone have found that these were associated with a higher risk of blood clots than some other oral contraceptives without drospirenone. There have also been reports that drospirenone-containing pills may increase potassium levels, which can lead to hyperkalemia, a condition which can lead to serious heart rhythm disturbances. Additionally, oral contraceptives are associated with an increased risk of gallstones and gallbladder disease. In February 2010, Bayer started a $20 million dollar corrective advertising campaign for Yaz after the FDA found the company overstated the drug's benefits while minimizing its risks.
