Science Says: New Contraceptive Pills Caused by Increased Likelihood of Blood Clots


Newer versions of your pill may raise a woman’s potential for dangerous thrombus much more than older versions, a UK study suggests.

Women taking any combined oral contraceptive pills-containing both estrogen and progestin-were 3x as very likely to make a blood clot inside of a deep vein inside leg or pelvis, in comparison to women but not on the Pill. The danger was higher still considering the newer Pill versions except one, researchers found.

“This association is between 1.5 and 1.8 times higher with the newer formulations,” said lead author Yana Vinogradova, a probe fellow in medical statistics with the University of Nottingham.

The blood clots, often known as venous thromboembolisms (VTEs), are widespread and could be deadly should the clot dislodges and travels for the heart, brain or lungs. They are more established among women taking estrogen medicines, along with the risk is even higher if the woman smokes, according to the National Library of drugs.

But the actual likelihood of a blood clot for females on any combined oral contraceptives continues to be relatively low: between six and 14 extra cases a year per 10,000 women bringing the drugs, Vinogradova told Reuters Health by email.

Newer combined pills, such as progestins drospirenone, desogestrel, gestodene or cyproterone acetate, have already been suspected of carrying an excellent higher clot risk when compared to older versions that is included in levonorgestrel and norethisterone.

To assess VTE risk girls for older and newer-generation pills, they analyzed UK general practice databases since the period between 2001 and 2013. They found 5,062 installments of VTE among women ages 15 to 49, and matched each one of these women with as much as five women that were without a blood clot during the same year, but were of similar age and treated in a similar medical practice.

The researchers made up smoking, consumption of alcohol, race, body mass index as well as other health issues, determined that females taking any combined oral contraceptive were almost three times as about to suffer a blood clot as those failing to take contraceptive pills.

Women taking older-generation drugs were about 2.Five times as more likely to possess a blood clot as women not taking any oral contraceptives over the previous year. Those taking newer different kinds of combined pills were around four times as prone to suffer a clot when compared to women failing to take oral contraceptives.

The newer pills carry higher clot risk, but were introduced as potentially having new benefits at the same time, including reduced acne, headache, depression, weight-gain, breast symptoms and breakthrough bleeding, she said.

Any girls that are preoccupied should discuss treatments making use of their doctor inside their next routine appointment, Vinogradova said.

“Some women have a and the higher of (blood clot) as a result of family tree or other health conditions and doctors will already take account of such factors when advising women regarding their methods of contraception,” she said.
