Perhaps it is only prescribed for up to 6 months when used solely as an anti-acne medicine and not also as a contraceptive? I am not medically qualified and only your own GP can assess whether you are at any particular higher risk from taking Dianette (or any other oral contraceptive), e.g. due to age, weight or being a smoker. I have been taking Marvelon for nearly 10 years now and about 6 years ago it was one of three contraceptives identified as causing a higher risk of developing deep vein thrombosis etc. I saw two GPs at my local surgery who objectively pointed out the pros and cons (and also reminded me that being pregnant carries a far greater risk of thrombosis) and I decided to keep taking Marvelon, as it caused me no adverse effects whatsoever, unlike a couple of brands I had tried before settling on Marvelon. If you have been taking Dianette for 8 years with no problems then that pretty much suggests that it suits you. When we read of women who have suddenly died of DVT etc as a result of taking the pill, a common link is that many of them suffered within only a few weeks or months of starting to take the pill. I'm not saying that it means you are 'safer' just because you have been taking Dianette over a longer period, but we do have to put these things in perspective. Yes, taking the pill does carry some risks, as do numerous other daily activities, but as long as we understand them we can make an informed decision. But do see your GP for peace of mind!
