Ok, so pretty soon I'm going to have to change my screen name because I'm not going to be so happy if this thinning hair thing doesn't stop soon. I started on Metoprolol for elevated BP about 7 months ago, although my pressure and heart rate are improved I'm finding my hair is really thinning out. Which in turn, is stressing me out and probably raising my BP. Just wondering if anyone else has had this side effect and if so, if you stopped the med did it improve. Thanks.
