My doctor once told me that I could take it for 2 years max I believe. They let me take it a few years later again. The problem is that it's a very short-term fix as it's dangerous to take long term. It might be better to try a different pill for the longer term? I find it best to research pills before going to the doctors though as, depending on your country and doc, they tend to start with the cheapest pill and work their way up, even when you say it's for treating acne!! (This happened to me anyway!). I often read good things about Yaz!
