I am a 50 year old female currently on 100 mg of prometrium per day. I have been experiencing symptoms such as insomnia, headaches, stroke-like symptoms of incoordination, not been able to focus, slurred speech at times, and just not feeling like myself. I have been on prometrium since I was 40 years old, but to early menopause. I am questioning whether to change my dosage of this or even discontinue the use.
