If you take too much nadolol, you could experience overdose symptoms such as low blood sugar, constriction of the airway, and low heart rate. The specific effects of an overdose will be different for each person, depending on how much nadolol was taken and whether it was taken with other substances. Treatment for an overdose may involve "pumping the stomach," dialysis, or supportive care.

Treatment for a Nadolol Overdose

The treatment for an overdose will vary. If the overdose was recent, a healthcare provider may give certain medicines or place a tube into the stomach to "pump the stomach."

  • Giving medications to increase the heart rate
  • Giving IV fluids and medications to increase blood pressure
  • Giving asthma medications to reverse airway constriction
  • Giving IV glucose to reverse low blood sugar.
It is important that you seek medical attention immediately if you believe that you may have overdosed on this drug.
