Metoprolol Tartrate and metropolol

I've been on Toprol for many years due to the Synthroid medication makes my heart race and the Toprol slows it down. I've gone on the generic Toprol, the Metoprolol Tartrate and since I've gone on that, I've notice a lot of hair loss. I never dreamed this med would cause hair loss. Then I read that sheet that comes with the med and it said hair loss is one of the side effects. Has anyone else experienced this? My hair is coming out a lot and it's scary.

Okay, here's one you probably haven't heard before.
Have been taking Toprol for several years. A week ago, my pharmacist switched my prescription to the generic Metropolol. I took the 7th pill yesterday morning. Last night, I had a weird dream about a flood and I awake to find I had wet the bed! Almost 60 years old and wetting the bed? It has to be from the metroprolol. That's the only thing that has changed!
