metoprolo er vs metoprolo 2 times a day
Hi All- I went to my pharmacy today to pick up my script of metoprolol er and they said there was a nation wide shortage?? So they said they have a call into my GP to get they metoprolol that you take twice a day?? Is there a difference in these two other than one is extended release and one is not?? And will there be any side effects from changing??
