Women who use birth control patch are twice as likely to develop clots in comparison to those on the pill, a new study has found. Recently, another study conducted on similar grounds has revealed that there is no such risk. With controversial data from both sides, women who use the patch have been urged to discus their risk with the health care provider by the FDA.
Women who use the patch may be at an increased risk for thromboembolic events or clots in the lungs and legs. The risk of non-fatal blood less in women who do not use contraceptive is 1 in 10, 000. In women who use either the patch or pill, this may raise to anything between 3 and five.
In a pre-approval study conducted on nearly 3000 women, only two instances of blood clots have been recorded so far. The drug manufacturer has stated that a small amount of risk is indeed associated with all forms of contraception. Owing to the overlapping confidence levels of the two contraceptive methods, there may either be no risk or more than double the risk, in the opinion of researchers.
