Does Inderal Cause Low Blood Sugar?
Low blood sugar levels have been reported in people taking
Inderal® (
propranolol hydrochloride), as well as with other
beta blockers. This side effect is more common in infants, children, and people with kidney disease or
diabetes. It is also more common after prolonged exercise or while fasting (such as before surgery).
Symptoms of Low Blood Sugar With Inderal
Symptoms of low blood sugar can vary, depending on a number of factors, including how low the levels are.
Examples of early symptoms may include:
- Sweating
- Shakiness
- Extreme hunger
- Dizziness
- Cold sweats
- Blurry vision.
More severe symptoms 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 an increase in
blood pressure. However, in people taking Inderal, low blood sugar symptoms may not occur because of the effects of the medicine. Therefore, Inderal can "mask" these important symptoms, perhaps making low blood sugar less noticeable and, therefore, more dangerous.
