Opioids are frequently used first line to manage acute pain in a variety of settings; however, the use of nonprescription analgesics for acute pain is recognized by experts as a practical and effective opioid-sparing strategy. Variations in dosages and formulations and a lack of standardization in reporting clinical data hinder the awareness of nonprescription treatments and recommendation of their use before opioids and other prescription options. A fixed-dose combination (FDC) of two common nonprescription analgesics, ibuprofen (IBU) and acetaminophen (APAP), is an appealing alternative to opioids in acute pain settings with a range of potential benefits. This narrative review evaluates the evidence in support of IBU/APAP FDCs containing IBU (≤1200 mg/day) and APAP (≤4000 mg/day), the nonprescription maximum daily doses in Canada and the United States, as alternatives to opioids and as a means to reduce the need for rescue opioid medication in acute pain management. A literature search was performed to identify clinical studies that directly compared IBU/APAP FDCs with opioids or nonopioids and measured the need for opioid rescue therapy in acute pain. Across studies, IBU/APAP FDCs consistently demonstrated pain relief similar to or better than opioid and nonopioid comparators and reliably reduced the use of rescue opioids with fewer adverse events. Based on these data, healthcare clinicians should consider FDC nonprescription analgesics as a potential first-line option for the management of acute pain.

The growing trend of opioid-sparing treatment demands effective nonopioid pain management solutions. A fixed-dose combination (FDC) of ibuprofen and acetaminophen (IBU/APAP) has shown promise as an alternative to opioids in a range of pain management scenarios, but the available data are limited and can be difficult to compare across studies. In this review, the authors performed a comprehensive evaluation of the clinical studies that assessed the use of IBU/APAP FDCs as a means to prevent or decrease the use of opioids for patients with acute pain. In the included studies, IBU/APAP FDCs consistently and safely provided pain relief that could replace or reduce the need for opioids across a range of procedures. This manuscript can serve as a resource for healthcare clinicians when considering the use of IBU/APAP FDC treatments for acute pain management.
