Managing Delirium Symptoms: Are Oxycodone and Oxycontin the Cause? - Pharmacology

What should be done to address the phenomenon of delirium?


My father is currently hospitalized due to cancer and is receiving targeted therapy.
He has also been diagnosed with a urinary tract infection, for which the doctor prescribed antibiotics and two pain medications: Oxycodone and Oxycontin.
As a result, he has experienced symptoms of delirium, and he has not improved two days after discharge.
I would like to know if this could be related to these two pain medications and whether he should consider adjusting or discontinuing them on his own.

Hello: Based on the situation you described, cancer, urinary tract infections, targeted therapy, antibiotics, and analgesics could all potentially cause delirium.
Currently, the information does not allow us to confirm the types of targeted therapy and antibiotics, as well as the stage of cancer, making it impossible to directly attribute the delirium to the analgesics.
It is recommended that you take your father back for a follow-up appointment immediately, so that the attending physician can diagnose and treat him.
We hope for your father's swift recovery!

More Info


Delirium is a serious and often reversible condition characterized by confusion, altered consciousness, and cognitive dysfunction. It can occur in hospitalized patients, particularly those with underlying health issues such as cancer, infections, or those undergoing significant medical treatments. In your father's case, the introduction of Oxycodone and Oxycontin for pain management may indeed be contributing factors to the development of delirium.

Oxycodone and Oxycontin are both opioid analgesics used to manage moderate to severe pain. While they are effective for pain relief, opioids can have a range of side effects, including sedation, confusion, and cognitive impairment, especially in older adults or those with pre-existing cognitive issues. The risk of delirium increases with the use of opioids, particularly when combined with other medications or in patients who are already vulnerable due to illness or age.

In addition to the direct effects of opioids, other factors in the hospital setting can contribute to delirium. These include changes in environment, sleep disturbances, dehydration, metabolic imbalances, and the presence of infections. In your father's case, the urinary tract infection (UTI) could also be a significant contributor to his altered mental status. UTIs are known to cause confusion and delirium, particularly in older adults.

It is crucial to approach the management of delirium carefully. Here are some considerations:
1. Consult with Healthcare Providers: Before making any changes to your father's medication regimen, it is essential to discuss your concerns with his healthcare team. They can evaluate the situation, consider the potential contributions of the opioids to his delirium, and determine the best course of action.

2. Medication Review: The healthcare team may consider adjusting the dosage of Oxycodone and Oxycontin, switching to a different pain management strategy, or tapering off the opioids if they are deemed to be contributing to the delirium.

3. Address Underlying Causes: Treating the urinary tract infection effectively may help alleviate some of the delirium symptoms. Ensuring that your father is well-hydrated and that any metabolic imbalances are corrected is also crucial.

4. Non-Pharmacological Interventions: In addition to medication adjustments, non-pharmacological strategies can help manage delirium. These may include ensuring a calm and familiar environment, promoting good sleep hygiene, and engaging your father in orientation activities (e.g., talking about the date, time, and familiar people).

5. Monitoring: Close monitoring of your father's mental status is essential. If there is no improvement or if symptoms worsen, further evaluation may be necessary to rule out other causes of delirium.

In summary, while Oxycodone and Oxycontin can contribute to delirium, it is essential to consider all factors involved in your father's condition. Open communication with his healthcare providers is critical to ensure that he receives the best possible care and that any necessary adjustments to his treatment plan are made safely.
