Hello. I m sorry you re suffering from headaches. Unfortunately, some women do develop migraines as they enter menopause, presumably due to falling estrogen and progesterone levels. I presume you re at an age where menopause is more or less certain; if there s any doubt that you re really menopausal (and that some other condition isn t the cause of your lack of menstrual periods), your doctor can measure your follicle stimulating hormone (FSH) level. This is a simple blood test. Sibelium is one of many medications doctors use to treat migraine headaches. You didn t mention if this medication helped when you first took it four years ago, but if it did, it s certainly worth taking again. If the Sibelium didn t help your headaches four years ago, you may want to talk to your doctor about other options. In some women with menopausal migraines, hormone therapy is beneficial; progesterone alone is often sufficient. I hope you feel better soon.
