When is oxycodone contraindicated?
Oxycodone is contraindicated in people with conditions where opioids could cause serious harm, especially breathing problems. Common contraindications include:
- Significant respiratory depression (dangerously slow or inadequate breathing) [1]
- Acute or severe bronchial asthma or other severe breathing obstruction [1]
- Known or suspected paralytic ileus (a blockage of the intestines due to loss of gut movement) [1]
- Hypersensitivity (allergy) to oxycodone or any of the product ingredients [1]
What about “impaired breathing” situations?
Clinicians generally treat any high-risk breathing scenario as a red flag for opioid use. Oxycodone is contraindicated when there is already respiratory compromise, such as significant respiratory depression, because opioids can further suppress breathing [1]. In severe asthma or comparable airway disease, the risk of worsening oxygenation and ventilation is also a key reason for the contraindication [1].
Can oxycodone be used if you have bowel blockage or severe constipation?
Oxycodone is contraindicated with paralytic ileus, which is a specific concern related to gut motility (opioids can slow or stop intestinal movement) [1]. If a person has symptoms suggesting bowel obstruction or severe ileus, clinicians typically avoid oxycodone and evaluate urgently.
Who should not take oxycodone due to allergy?
If someone has had a prior allergic reaction to oxycodone (or a hypersensitivity to ingredients in the oxycodone product), oxycodone should not be used [1].
Are there contraindications for specific oxycodone formulations?
Contraindications can vary by product label (for example, immediate-release vs extended-release formulations, or combination products). The core contraindications above are typically consistent across oxycodone labels, but the exact wording and any additional “do not use” situations can differ by manufacturer. Check the specific package insert for the exact oxycodone product you mean [1].
