How do I transition a patient from Dilaudid (hydromorphone) to a Butrans (buprenorphine) patch?

Transitioning from Hydromorphone (Dilaudid) to Butrans (Buprenorphine) Patch

When transitioning a patient from hydromorphone (Dilaudid) to Butrans (buprenorphine) patch, first calculate the 24-hour hydromorphone requirement, convert to morphine equivalents, then select the appropriate Butrans patch strength using established conversion tables, and reduce the calculated dose by 25-50% to account for incomplete cross-tolerance. 1, 2

Step-by-Step Conversion Process

Step 1: Calculate Total Daily Hydromorphone Dose

• Determine the total amount of hydromorphone the patient is taking in a 24-hour period
• Include all scheduled and as-needed doses

Step 2: Convert to Morphine Equivalents

• Use standard conversion ratios:
  • Oral hydromorphone to oral morphine = 1:4 ratio
  • IV/SubQ hydromorphone to IV/SubQ morphine = 1:5 ratio 1, 2
  • Example: 30mg oral hydromorphone daily = 120mg oral morphine equivalent

Step 3: Select Appropriate Butrans Patch Strength

• Based on the NCCN conversion table for transdermal buprenorphine 1:
  • 25 mcg/h patch ≈ 60mg oral morphine or 7.5mg oral hydromorphone daily
  • 50 mcg/h patch ≈ 120mg oral morphine or 15mg oral hydromorphone daily
  • 75 mcg/h patch ≈ 180mg oral morphine or 22.5mg oral hydromorphone daily
  • 100 mcg/h patch ≈ 240mg oral morphine or 30mg oral hydromorphone daily

Step 4: Reduce Dose for Cross-Tolerance

• Reduce the calculated dose by 25-50% to account for incomplete cross-tolerance 1, 2
• Example: If calculations indicate a 50 mcg/h patch, consider starting with a 25 mcg/h patch

Important Clinical Considerations

Timing of Transition

• Due to buprenorphine's high binding affinity for μ-opioid receptors, traditional approaches recommend waiting until the patient is in mild withdrawal before initiating buprenorphine 1
• However, newer approaches suggest using transdermal buprenorphine as a bridge to avoid the painful abstinence period 3
• For patients on lower doses of hydromorphone, apply the Butrans patch 12-24 hours after the last hydromorphone dose
• For patients on higher doses, consider a more gradual transition with overlapping therapy

Breakthrough Pain Management

• Provide short-acting non-opioid analgesics for breakthrough pain during the first 24-72 hours 1
• Options include NSAIDs, acetaminophen, or adjuvant medications appropriate to the pain syndrome
• Avoid using full opioid agonists for breakthrough pain if possible, as buprenorphine's high receptor affinity may block their effects 1

Monitoring and Dose Adjustments

• Assess pain control after 72 hours (when buprenorphine reaches steady state)
• Butrans patches are typically changed every 7 days 4
• If pain control is inadequate:
  • Increase to the next patch strength
  • Consider dividing buprenorphine doses if using sublingual formulations 1

Special Considerations

• Patients previously on very high doses of hydromorphone (>30mg oral daily) may have more difficulty transitioning and may require more careful monitoring 5
• Patients with renal or hepatic impairment may require lower starting doses
• Elderly patients may be more sensitive to both medications and may require dose reductions

Potential Challenges and Solutions

Inadequate Pain Control

• If maximum Butrans dose is reached with inadequate analgesia, consider adding a full opioid agonist under close monitoring 1
• Higher doses of full agonists may be needed due to buprenorphine's high receptor affinity 1

Withdrawal Symptoms

• If withdrawal symptoms occur, consider using the transdermal buprenorphine as a bridge method 3
• For severe cases, consider a microdosing approach with gradually increasing buprenorphine while tapering hydromorphone 6

Adverse Effects

• Monitor for common side effects: nausea, constipation, headache, dizziness
• Transdermal buprenorphine typically has fewer gastrointestinal side effects than sublingual formulations 7
• Assess for local skin reactions at patch application sites 4

By following this structured approach, you can safely transition patients from hydromorphone to Butrans patches while minimizing withdrawal symptoms and maintaining adequate pain control.
