Re: Metoprolol Tartrate vs Toprol XL
I am the opposite of your situation, I switched from Metoprolol tartrate to Toprol XL last month. When I was on Metroprolol it was usually twice a day, but I sometimes had to take it 3 times a day, depending on what I ate that day (some foods affected my heart rate). I switched to Toprol XL since I would only need to take it once a day.
For me, I don't think its as effective as generic Metoprolol. I find the effects wear off after to 12 hours or so, plus its much more expensive than generic Metoprolol tartrate. Also a couple hours after I take it (Toprol XL) I feel like a Zombie for about 30 mins, I think this is when the medication starts to kick in. For this reason I have to get up at 5 am to take the medication and then go back to bed so I can avoid the Zombie phase when I drive in the morning.
When I go back to the doctor next year, I am going to ask to switch back to generic Metropol Tartrate. For me it works much better and I don't mind taking it more than once a day.
You can also ask about switching to Atenolol, this is also 1 daily and available in a generic form.
