≥16 years

• Short-term (generally <10 days) management of acute pain
• Lowest effective dose for the shortest duration consistent with individual patient treatment goals
• Usual dose: 5-7.5 mg/200 mg PO q4-6 hr PRN; not to exceed 5 tabs/24hr

Contraindicated (1)

• alvimopan

  alvimopan, hydrocodone. receptor binding competition. Contraindicated. Alvimopan is contraindicated in opioid tolerant patients (ie, those who have taken therapeutic doses of opioids for >7 consecutive days immediately prior to taking alvimopan). Patients recently exposed to opioids are expected to be more sensitive to the effects of alvimopan and therefore may experience abdominal pain, nausea and vomiting, and diarrhea. No significant interaction is expected with concurrent use of opioid analgesics and alvimopan in patients who received opioid analgesics for 7 or fewer consecutive days prior to alvimopan.
