I started taking topamax for migraines. It had the added benefit of helping to level out moods for BP that I was able to come off the last med I was on for stabilization. However, I have heard mixed reviews as to whether or not it helps with BP, sometimes so, many times not. I have not had increased anxiety with it but rather it has helped reduce it. It is important to stay hydrated on it though as it can cause urinary crystals and kidney stone formation.
Best wishes in finding what works best and hope you finding the right one soon.
