Can a Patient Take Trazodone with Oxycodone?

Yes, a patient with chronic pain and insomnia can take trazodone with oxycodone, but this combination requires caution due to additive sedative effects and should only be considered after safer alternatives have been tried. 1

Safety Considerations for This Combination

The concurrent use of trazodone with oxycodone carries risk due to additive sedative effects. 1 Both medications cause central nervous system depression, which can result in:

• Enhanced drowsiness and sedation
• Increased risk of psychomotor impairment 2
• Greater fall risk, particularly in elderly patients 2
• Potential for respiratory depression when combined with opioids

Treatment Algorithm for Insomnia in Chronic Pain Patients

First-Line Approach

Cognitive Behavioral Therapy for Insomnia (CBT-I) should be the initial treatment, including stimulus control therapy, sleep restriction therapy, and relaxation techniques. 1 This avoids polypharmacy and addresses the root cause of insomnia without adding medication risks.

Second-Line Pharmacologic Options (Before Trazodone)

If CBT-I fails or is unavailable, consider FDA-approved hypnotics first:

• For sleep onset and maintenance: Eszopiclone 2-3 mg, zolpidem 10 mg, or temazepam 15 mg 1, 3
• For sleep onset only: Zaleplon 10 mg or ramelteon 8 mg 1, 3
• For sleep maintenance only: Suvorexant or low-dose doxepin 3-6 mg 1, 3

Third-Line: Trazodone Consideration

Trazodone should only be considered after benzodiazepine receptor agonists and ramelteon have failed. 1 The American Academy of Sleep Medicine recommends against trazodone for insomnia based on 50 mg dose trials, giving it a "WEAK" recommendation due to:

• Only modest improvements in sleep parameters compared to placebo 1, 3
• No significant improvement in subjective sleep quality 1
• Potential harms outweighing benefits 1

If Trazodone Is Used with Oxycodone

Dosing Strategy

Start with the lowest effective dose of trazodone (25-50 mg at bedtime) when insomnia is refractory to other treatments. 4 Note that doses used for insomnia are below the therapeutic antidepressant range. 1

Mandatory Patient Education

Patients must be counseled about: 1

• Daytime drowsiness risk: Allow adequate sleep time (7-8 hours) before activities requiring alertness
• Fall precautions: Particularly important given opioid co-administration
• Avoid alcohol: Compounds sedative effects
• Take on empty stomach: Maximizes effectiveness 1
• Signs of excessive sedation: Confusion, difficulty breathing, extreme drowsiness

Monitoring Requirements

Regular follow-up every few weeks initially to assess: 1

• Effectiveness for insomnia symptoms
• Adverse effects (sedation, dizziness, orthostatic hypotension)
• Signs of tolerance development 2
• Ongoing need for both medications
• Opportunities to taper either medication

Special Populations Requiring Extra Caution

Elderly Patients

Dose reduction should be strongly considered due to increased risk of: 1

• Falls and fractures from combined sedation
• Cognitive impairment 2
• Orthostatic hypotension

Patients with Respiratory Compromise

Avoid this combination in patients with: 1

• Chronic obstructive pulmonary disease
• Sleep apnea
• Compromised respiratory function

The combination of an opioid (which suppresses respiratory drive) with a sedating antidepressant significantly increases respiratory depression risk.

Patients with Cardiac Conditions

Exercise caution in patients with heart failure or cardiac conduction abnormalities, as trazodone has been associated with cardiac adverse effects. 1, 2, 5

Common Pitfalls to Avoid

• Do not use trazodone as first-line therapy for insomnia in opioid-treated patients 1
• Do not combine two sedating antidepressants with opioids 3
• Do not prescribe without attempting CBT-I or FDA-approved hypnotics first 1
• Do not use long-acting opioids (extended-release oxycodone, fentanyl patches) for acute pain 4
• Do not ignore constipation management when prescribing opioids—use stool softeners and laxatives prophylactically 4

Opioid Management Considerations

For patients on chronic opioid therapy: 4

• Monitor for opioid-induced hypogonadism in symptomatic patients (sexual dysfunction, depression, osteoporosis)
• Manage constipation proactively with scheduled bowel regimen
• Assess for tolerance and dependence at regular intervals
• Consider opioid rotation if pain control is inadequate despite dose escalation

When This Combination May Be Appropriate

Trazodone combined with oxycodone may be reasonable when: 4, 1

• Insomnia persists despite adequate pain control with opioids
• First and second-line insomnia treatments have failed
• Comorbid depression exists (though higher antidepressant doses would be needed)
• Patient is closely monitored for adverse effects
• Benefits clearly outweigh risks in the individual patient's context

The key principle is to employ the lowest effective doses of both medications and actively work toward tapering when conditions allow. 1
