Does Metoprolol Cause Low Blood Sugar?
Low blood sugar levels have been reported in people taking
metoprolol (available as
Lopressor®,
Toprol XL®, and
generic metoprolol) along with other beta blockers. This side effect is more common in infants and children, while fasting (such as before surgery), after prolonged exercise, or in people with kidney disease or
diabetes.
Metoprolol and Low Blood Sugar Symptoms
Low blood sugar symptoms can vary depending on a number of factors, including how low the blood sugar levels are.
Examples of early symptoms may include:
- Sweating
- Shakiness
- Extreme hunger
- Dizziness
- Cold sweats
- Blurry vision.
More severe symptoms of low blood sugar can include:
- Changes in behavior, such as irritability
- Loss of coordination
- Difficulty speaking
- Confusion
- Seizures
- Loss of consciousness
- Coma
- Loss of life.
Two other symptoms that can occur in people with low blood sugar are an increase in heart rate and
blood pressure. In people taking metoprolol, these two low blood sugar symptoms may not occur because of the effects of the medicine.
