MedicalResearch.com: What is the background for this study? Would you briefly describe the type of acne treated with Isotretinoin?
Response: Isotretinoin is often used to treat moderate to severe acne or acne that has been unresponsive to other treatments. It is also used for patients with scarring acne. While highly effective for acne, due to concerns about medication related side-effects, patients are often monitoring with frequent blood tests, sometimes up to once per month.
However, there have been several studies over the past two decades questioning the value of these frequent blood tests for patients on isotretinoin for acne. The purpose of this study was to examine whether blood test monitoring has been decreasing over time in response to these studies. We also evaluated the frequency of blood test abnormalities for patients being treated with isotretinoin.
