4 Opioid Safety

Why opioid safety matters

Opioids can relieve pain, but excessive dosing or increased sensitivity to the drug can cause dangerous sedation and slowed or stopped breathing. Treat opioids as high-alert medications: follow the order, product instructions, and facility policy, and combine careful dose verification with assessment before and after administration.

Verify the dose and patient-specific risks

Before administration, verify the patient, medication, dose, route, time, and indication. Check allergies, the medication record, and relevant orders. Confirm the formulation and concentration, especially for liquid, extended-release, and transdermal products. Stop and clarify any unclear or apparently unsafe order, or a discrepancy between the package and medication record; do not estimate a dose or rely on memory.

Consider opioid tolerance, recent opioid doses, age, health conditions, and other sedating medicines. These include alcohol, benzodiazepines, and gabapentinoids. Use the lowest effective dose prescribed. Do not independently increase a dose or substitute one opioid for another.

Assess and respond to changes

Assess pain, alertness, respiratory rate and effort, and oxygenation as appropriate before and after giving an opioid. Do not assess pain alone: sedation can precede respiratory depression, so new or increasing sleepiness is a warning sign rather than merely evidence that the patient is comfortable.

Follow facility policy for reassessment timing and monitoring. Observe more closely when an opioid is started, increased, or given by a higher-risk route, and when the patient has risk factors such as sleep-disordered breathing or concurrent sedatives. Document administration and reassessment, and promptly report unexpected sedation, inadequate pain relief, or other adverse effects.

If the patient is unusually difficult to awaken or breathing is slow, shallow, or abnormal, do not give another opioid dose. Stay with the patient, summon help, and follow the emergency protocol.

Use PCA safely

With patient-controlled analgesia (PCA), teach that only the patient should press the dose button, if able. A family member or staff member must not press it for a sleeping or sedated patient. PCA by proxy can deliver an opioid when the patient may be too sedated to protect their breathing. If a sleeping patient's pain is raised as a concern, assess the patient and contact the care team as needed rather than allowing someone else to activate the button.

Recognize and respond to suspected overdose

Possible opioid-overdose signs include inability to awaken, slow or shallow breathing, choking or gurgling sounds, and blue or gray lips or fingertips. If overdose is suspected, activate emergency help immediately. Do not wait to see whether naloxone works before calling for help or supporting breathing.

Support breathing, and begin CPR or rescue breathing if indicated and within your training. Administer naloxone according to the emergency order, product instructions, and facility protocol, and stay with the person.

Continue care after naloxone

Naloxone can temporarily reverse opioid effects, but respiratory depression may return because many opioids last longer than naloxone. Continue close observation and repeat naloxone when indicated by the product instructions or clinical protocol. Emergency medical assessment is still required even if the person wakes up and begins breathing more normally.

Naloxone may trigger acute withdrawal in a person who is physically dependent on opioids. The immediate priority remains restoring and maintaining adequate breathing.
