Downsides
- You need to take Lopressor (metoprolol tartrate) with food twice a day for it to work best.
- Taking Lopressor (metoprolol tartrate) may make you feel more tired or out of breath during exercise or your normal daily routines. This gets better for most people, but for some it may not go away.
