This may be especially noticeable when:
Standing up quickly
Getting out of bed
Starting treatment
Increasing the dose
Exercising
Becoming dehydrated
Taking other blood-pressure-lowering medicines
Standing up gradually can sometimes reduce symptoms related to a sudden drop in blood pressure.
If dizziness is severe, frequent, or accompanied by fainting, chest pain, confusion, or difficulty breathing, medical evaluation is important.
Driving and Dizziness
Until you know how metoprolol affects you, be cautious with driving, operating machinery, or other activities in which dizziness or unusual fatigue could create a safety risk.
3. Slow Heart Rate
A slower heart rate is an expected pharmacological effect of metoprolol.
That is often one of the reasons the medication is prescribed.
However, in some people the heart rate can become slower than intended.
Possible symptoms associated with excessive slowing include:
Weakness
Dizziness
Fainting
Unusual fatigue
Shortness of breath
Reduced exercise tolerance
Confusion in some individuals
The meaning of a specific pulse rate depends on the individual. Athletes, for example, may naturally have relatively slow resting heart rates.
