From the FDA Drug Label

Acute overdose with hydromorphone hydrochloride tablets can be manifested by ... bradycardia, ...

  • Bradycardia is listed as a potential manifestation of acute overdose with hydromorphone hydrochloride tablets.
  • The presence of bradycardia in the context of overdose suggests that hydromorphone can cause bradycardia in certain situations, such as overdose 1.

From the Research

Yes, Dilaudid (hydromorphone) can cause bradycardia, which is an abnormally slow heart rate. As a potent opioid analgesic, Dilaudid affects the central nervous system and can stimulate the vagus nerve, leading to decreased heart rate. This medication works by binding to opioid receptors in the brain, spinal cord, and other areas, which not only provides pain relief but also affects various bodily functions including cardiovascular regulation.

Key Points to Consider

  • The risk of bradycardia is dose-dependent and more likely to occur with higher doses or rapid intravenous administration, as noted in a study published in 2011 2.
  • Patients with pre-existing cardiac conditions, elderly individuals, and those taking other medications that slow heart rate are at increased risk for this side effect.
  • Healthcare providers typically monitor vital signs when administering Dilaudid, especially in hospital settings.
  • If bradycardia occurs, dose reduction or discontinuation may be necessary, and in severe cases, medications like atropine might be used to increase heart rate.
  • Patients should report symptoms such as dizziness, lightheadedness, or unusual fatigue which could indicate bradycardia.

Mechanism and Risk Factors

The exact mechanism by which hydromorphone causes bradycardia is not fully understood, but it is thought to involve the stimulation of the vagus nerve and the binding of opioid receptors in the central nervous system. A study published in 2015 3 discussed the cardiac effects of opioid therapy, including the potential for bradycardia and vasodilation.

Monitoring and Management

It is essential to monitor patients closely for signs of bradycardia when administering Dilaudid, especially in high-risk populations. If bradycardia occurs, healthcare providers should be prepared to take prompt action, including dose reduction or discontinuation of the medication, and administration of medications to increase heart rate if necessary.

Conclusion Not Applicable - Direct Answer Only

The most critical consideration is the potential for hydromorphone to cause bradycardia, and healthcare providers should be aware of this risk when prescribing the medication. A study published in 2011 2 highlighted the importance of monitoring patients for signs of bradycardia when administering hydromorphone.
