Newer contraceptive pills may be linked to risk of blood clots

A new study has suggested that the new contraceptive pills might be linked to higher risk of serious blood clots.

The team of researchers from Nottingham University said that they found that the users of any combined oral contraceptive are at an increased risk of the serious blood clots known as venous thromboembolism (VTE) when compared to those who did not take any contraceptive.

The researchers found that the pills with newer types of progestogen hormone including drospirenone, desogestrel, gestodene, and cyproterone are linked to a higher risk of VTE than pills containing older progestogens such as levonorgestrel and norethisterone.They said that the risk for women using newer pills was around 1.5-1.8 times higher than for women who used pills containing older progestogens.

They said that women using older contraceptives have two and a half times increased risk of VTE than those not using oral contraceptives at all. On the other hand, women using newer pills have four times increased risk of VTE compared to women who did not use oral contraceptives.The study involved analysing prescription information from two UK general practice databases involving women in the age group of 15-49 years.

The results were published in the BMJ.
