Hello i am 27 years old and I am on cabergoline, a medicine to shrink my pituitary tumor…however, I am on my last dosage of the medicine and my period has not come back yet, and when I told my primary care doctor this she was shocked and said to continue to follow up with the endocrinologist. I saw my endocrinologist last month and he said he will check for Cushing’s disease, and I go in september to do the test. He didnt seemed very worried. I was wondering what disease’s or problems can cause the medicine to not work? Also although my tumor is a microadenoma I have decreased peripheral vision. I took a visual fields test a while ago and failed. Is this loss permanent? I don’t think it’s safe to drive and my parents help drive but they are assuming this is a temporary thing. Even my mom told me I will drive soon.
