Women May Be Using Unsafe Oral Contraceptives

Various brands of oral contraceptives have been linked to a heightened risk of contracting venous thrombosis. Venous thrombosis – a blood clot forming inside a vein – may cause soreness, but the infection in itself has no serious effects. Venous thrombosis can easily lead to a pulmonary embolus. This is where a piece of a blood clot formed in a vein breaks off and eventually ends up in the lungs. This disease is very serious and may be deadly if left untreated.

A study conducted in the Netherlands compared 1524 patients diagnosed with either venous thrombosis or pulmonary embolism and 1760 healthy patients who were not using oral contraceptives. The women using oral contraceptives had 5 times more of a risk of contracting venous thrombosis than the women not using oral contraceptives.

A follow up study was conducted in Denmark. Healthy women between 15 and 49 years old were studied. A total of 4213 cases of venous thrombosis were found; 2045 of these causes were from women using oral contraceptives.

The type of progestogens in the contraceptives affected the risk of contracting venous thrombosis. When you 1st begin using oral contraceptive your risk of getting venous thrombosis will be high, regardless of what brand you use. Levonorgestrel, a type of progestogen, has the lowest risk of contracting venous thrombosis. The progestogens providing the highest risk of contracting venous thrombosis are gestodene, desogestrel, drospirenone, and cyproterone acetate.

The best oral contraceptives that can be used are those with a low level of oestrogen. Levonorgestrel or norethisterone are fine to have in oral contraceptives. The most recent progestogens are more likely to cause venous thrombosis. The risk of getting venous thrombosis is low (only 5 in 100,000 people), but when using oral contraceptive the risk increases up to 25 in 100,000 people.
