I was prescribed Buspar 7.5mg two times a day for my anxiety. I am afraid to try it as I had a serious adverse reaction to Lexapro-made my heart race then full panic attack after just one half dose. I am very sensitive to medication. I take metoprolol for high heart rate and high blood pressure and methimazole for hyperactive thyroid. My heart palpitations are constant now but pulse is normal and so is BP. However my anxiety is awful. Anyone have experience or insight taking Buspar? Any advice is greatly appreciated.
