Beta blocker overdose

Symptoms and Dangers of a Beta Blocker Overdose

Beta blockers, or beta-adrenergic blocking agents, can be lifesaving medications for people suffering from cardiovascular diseases such as angina, heart attacks, high blood pressure, and arrhythmias. These medications can also be taken to reduce the symptoms of anxiety and stress-related disorders. However, like with any medication, there is a risk of an overdose.

Signs and symptoms of a beta blocker overdose can include:

  • Extremely low blood pressure
  • Bradycardia (slow heart rate)
  • Dizziness or lightheadedness
  • Feeling faint or passing out
  • Shortness of breath
  • Confusion and confusion related to grieving
  • Nausea or vomiting
  • Drowsiness or fatigue

If you or someone you know is experiencing any of these symptoms, it's important to seek medical attention immediately. A beta blocker overdose can be fatal because it can lead to a heart attack or stroke. Once a patient has been treated, the underlying cause of the overdose will need to be determined and treated.

Treatments for Beta Blocker Overdose

Treatment for a beta blocker overdose may include the following steps:

  • Administering activated charcoal to prevent further absorption of the medication in the stomach.
  • Administering intravenous fluids to maintain hydration.
  • Administering medications to increase the heart rate.
  • Administering medications to support breathing.
  • Supportive care such as oxygen, ventilation and dialysis.

In cases where the overdose was taken with the intention of self-harm or suicide, the patient may need to be admitted for inpatient mental health treatment. This will ensure that the patient is supported and has the access to the resources and treatments needed to recover from the overdose.


The best way to prevent a beta blocker overdose is to make sure that you take your medication as prescribed by your doctor. It's important to be aware of the potential side effects of the medication, and to discuss any concerns that you may have with your doctor. You should also never take more than the recommended dose, and talk to your doctor before stopping or changing your dosage.

It's also important to be aware of the overdose risk of beta blockers in children. All medications should be stored in a safe and secure place, and out of the reach of children.
