medication starts to work within 1 hour, but you won’t see full results until about 1 week. You may not feel any different when you take metoprolol succinate (Toprol XL), but this doesn’t mean it’s not working.

Generally, beta blockers can worsen breathing problems in people with asthma, chronic obstructive pulmonary disease (COPD), or other lung conditions. Unlike non-selective beta blockers like carvedilol (Coreg), metoprolol succinate (Toprol XL) is selective to (specifically targets) the heart and not the lungs. So people who have asthma or COPD may have less side effects with metoprolol succinate (Toprol XL) than with other beta blockers. It’s still advisable to take the lowest possible dose of this medication that works for you to prevent worsened breathing problems. If you have any breathing problems, let your provider know before starting metoprolol succinate (Toprol XL).
