Do you have Cushing Syndrome ? Or does someone you know have this condition? What happens in this case is that our body produces more of the hormone cortisol than necessary, which causes the blood sugar level , that is, glucose, to increase. So, one of the medicines that doctors recommend at times like this is Mifepristone. Today, we will talk about these Mifepristone pills in detail.
What kind of medicine is Mifepristone?
Simply put, Mifepristone pills are mainly used to control blood glucose levels in the case of Cushing's Syndrome , a condition that occurs when the hormone cortisol in your body increases too much.
Do you know that this hormone called cortisol is indispensable for our body? When we are stressed, our body prepares itself to deal with it through this hormone. For example, when the body needs more energy immediately, this cortisol helps to release more sugar into the blood. However, when this increases uncontrollably, various problems arise. Mifepristone pills reduce the effect of the cortisol hormone, thereby reducing the blood sugar level.
This medication may sometimes be prescribed by doctors for other conditions. Therefore, if you are not sure exactly what this medication is for, it is best to ask your doctor or the pharmacist at the pharmacy where you pick up your medication. This medication is also known in the market by the brand name Korlym .
