Birth Control Methods
What Are The Risks?

In the past dangers associated with the contraceptive pill were limited to women aged over 35 and who also smoked. Today, newer and safer formulas afford a reasonably safe long term method of birth control for non-smoking women up until menopause. For most healthy women (regardless of age) who do not smoke, the chance of suffering severe side effects from the Pill is extremely unlikely. In fact, pregnancy in itself is much more dangerous. But for some women who have specific health problems (obesity or a family history of heart disease), the Pill can cause unwanted problems including liver cancer, blood clots and stroke. While these side effects are very rare, they can be deadly. Smoking cigarettes makes these problems more likely. The risk of death from taking oral contraceptives in nonsmoking women is 1 in 63,000, compared to 1 in 16,000 for smokers. This risk increases with age and by how much you smoke (heavy smoking is considered 15 cigarettes or more a day).

Risk Of Blood Clots

About 2 to 4 women in every 10,000 will experience a nonfatal blood clot. If you have a history of blood clots, stroke or heart attacks, you should not be prescribed the Pill. A recent study by the FDA investigated whether combination pills containing drospirenone (synthetic version of progesterone/progestin) had a higher risk of pulmonary embolism and deep vein thrombosis (DVT) - two rare but deadly types of blood clots. They concluded that they may be associated with a higher risk. Pills containing drospirenone include Yasmin, Yaz, Beyaz, Loryna, Syeda, Gianvi and Safyral.
