Diane 35 and thrombosis risk – Zembla broadcast

The oral contraceptive pill ‘Diane 35- was’ in the news again. I wrote about the diane-35 pill on this website before, even twice,  when there was a broadcast of the radio show Argos.

The first time I wrote:

[…] this is a bit strange: there is nothing new about the information that third and fourth generation oral contraceptives have an increased risk of thrombosis compared to the risk conveyed by second generation oral contraceptives. Because the desired effects of the older and newer generation pills are similar (not getting pregnant, preventing or curing acne) there is limited, if any, reason to prescribe the newest and more expensive pills. See also the recent comment by Helmerhorst and Rosendaal in the BMJ. However, still 160.000+ (Diane 35) 500.000 (third generation) women take these newer pills. […]

Those words also fit the broadcast of the TV show Zembla last week. Zembla has a reputation to be ‘activist reporters’ and some of the broadcast is not to my taste. It is however good to see that Zembla tried to figure out how it is possible that Diane-35, which is not registered as an anti-conception pill, still gets prescribed as such. However, the broadcast leaves me unsatisfied for it does not provide answers, or even get to talk to everybody they wanted to? (Why did they reporters did not proceed to work on their WOB? a missed change!)

As in the previous two blog posts on this topic, I feel like these story are important but they also need to have the proper amount of nuance. Therefore, also this time I conclude with saying that the absolute risk of thrombosis in young women (both venous and arterial) is very low, even when using oral contraceptives. But all unnecessary risk without any benefit that can be avoided should be avoided. As always, consult your GP if you have any questions.
