Starting Hydrocodone Dose for Hospice Patients with Pain
Start with 5 mg hydrocodone (combined with acetaminophen) every 4-6 hours as needed for opioid-naïve hospice patients with pain. 1
Rationale for 5 mg Starting Dose
The FDA-approved product labeling for hydrocodone/acetaminophen explicitly states that the usual adult dosage for the 5 mg/325 mg formulation is one or two tablets every 4-6 hours as needed, making 5 mg the appropriate starting point for opioid-naïve patients. 1
The CDC guidelines recommend that the lowest starting dose for opioid-naïve patients is often equivalent to a single dose of approximately 5-10 MME, and since hydrocodone has a 1:1 conversion to MME, a 5 mg dose falls within this recommended range. 2
The European Society for Medical Oncology (ESMO) cancer pain guidelines do not specifically list hydrocodone but recommend starting doses that align with the lower end of the spectrum for opioid-naïve patients. 2
Why Not Start with 10 mg
Starting with 10 mg doubles the opioid exposure unnecessarily in opioid-naïve patients and increases the risk of respiratory depression, particularly in the first 24-72 hours of therapy. 1
The FDA labeling indicates that 10 mg formulations are intended for patients who require higher doses, with a maximum of 6 tablets daily (60 mg total), suggesting this strength is for patients with established opioid tolerance or more severe pain. 1
The CDC emphasizes using the lowest effective dosage and calibrating based on pain severity and clinical factors such as age ≥65 years, renal or hepatic insufficiency—all common in hospice patients. 2
Dosing Algorithm for Hospice Patients
Initial dose:
- Start with hydrocodone 5 mg/acetaminophen 325 mg, one tablet every 4-6 hours as needed. 1
- For patients ≥65 years or with renal/hepatic impairment, consider using the 2.5 mg/325 mg formulation if available to allow for even more cautious titration. 2
Titration approach:
- Monitor closely for respiratory depression in the first 24-72 hours. 1
- If pain remains inadequately controlled after 24 hours, increase to two tablets (10 mg) every 4-6 hours, not exceeding 8 tablets daily (40 mg total hydrocodone). 1
- The American Thoracic Society emphasizes that the correct dose is the dose that relieves the symptom, with no maximum doses of opioids in palliative care. 2
Breakthrough dosing:
- Provide the same 5 mg dose available every 1-2 hours as needed for breakthrough pain. 3
- If more than 4 breakthrough doses are needed in 24 hours, increase the scheduled around-the-clock dose. 2, 3
Critical Safety Measures
Mandatory co-prescriptions:
- Prescribe a stimulant laxative and stool softener prophylactically from the first dose, as constipation is predictable with opioids. 2
- Have antiemetics readily available, as nausea is common in the first few days. 2
- Offer naloxone and overdose prevention education to the patient and household members. 2
Monitoring requirements:
- Follow patients closely for respiratory depression, especially within the first 24-72 hours. 1
- Reassess pain control and adverse effects frequently during initial titration. 1
- Watch for somnolence, which is often transient and resolves within days to weeks. 2
Common Pitfalls to Avoid
- Do not start with 10 mg in opioid-naïve patients—this unnecessarily increases overdose risk without evidence of superior pain control. 2
- Do not use transdermal fentanyl for initial opioid therapy—it is inappropriate for rapid titration and should only be used for chronic stable pain. 2
- Do not abruptly discontinue hydrocodone if the patient has been on it for more than a few days, as this can cause withdrawal symptoms. 1
- Do not exceed the maximum daily acetaminophen dose of 4000 mg (or 3000 mg in some guidelines), which limits total daily hydrocodone/acetaminophen tablets. 1
