A thorough pain assessment is vital to the initial evaluation of a patient and must be performed to guide treatment decisions. Dosing may be done incrementally and titrated to analgesic effect. Particularly in those without prior analgesic use, effects are variable and overdosing in these patients can result in adverse events. Individualize doses based on risk for adverse outcomes, prior effective doses, comorbidities, concomitant medications, and response to therapy.

When possible, use the same class of opioid analgesic for long-acting ie, hour scheduled doses and short-acting ie, PRN doses for breakthrough pain pain relief. Incomplete cross-tolerance can lead to greater than anticipated potency in a new opioid, even in the same class of analgesic. Methadone and fentanyl are generally safe and considered good options in patients with renal insufficiency.

For mild pain, the starting regimen should be a nonsteroidal anti-inflammatory drug NSAID or acetaminophen. For moderate pain, an opioid agonist eg, hydrocodoneoxycodone can be used. For severe pain, a higher potency opioid agonist eg, hydromorphonemorphinefentanyl can be used. The recommendations included the following: [ 67 ]. Nonpharmacologic therapy and nonopioid pharmacologic therapy are preferred for chronic pain.

Clinicians should consider opioid therapy only if expected benefits for both pain and function are anticipated to outweigh risks to the patient. If opioids are used, they should be combined with nonpharmacologic therapy and nonopioid pharmacologic therapy, as appropriate. Before starting opioid therapy for chronic pain, clinicians should establish treatment goals with all patients, including realistic goals for pain and function, and should consider how opioid therapy will be discontinued if benefits do not outweigh risks.

Clinicians should continue opioid therapy only if there is clinically meaningful improvement in pain and function that outweighs risks to patient safety. Before starting and periodically during opioid therapy, clinicians should discuss with patients known risks and realistic benefits of opioid therapy and patient and clinician responsibilities for managing therapy. When opioids are started, clinicians should prescribe the lowest effective dosage.

Long-term opioid use often begins with treatment of acute pain. When opioids are used for acute pain, clinicians should prescribe the lowest effective dose of immediate-release opioids and should prescribe no greater quantity than needed for the expected duration of pain severe enough to require opioids. Three days or less will often be sufficient; more than 7 days will rarely be needed. Clinicians should evaluate benefits and harms with patients within wk of starting opioid therapy for chronic pain or of dose escalation.

Clinicians should evaluate benefits and harms of continued therapy with patients every 3 mo or more frequently. If benefits do not outweigh harms of continued opioid therapy, clinicians should optimize other therapies and work with patients to taper opioids to lower dosages or to taper and discontinue opioids. Before starting and periodically during continuation of opioid therapy, clinicians should evaluate risk factors for opioid-related harms.

Clinicians should review PDMP data when starting opioid therapy for chronic pain and periodically during opioid therapy for chronic pain, ranging from every prescription to every 3 mo. When prescribing opioids for chronic pain, clinicians should use urine drug testing before starting opioid therapy and consider urine drug testing at least annually to assess for prescribed medications as well as other controlled prescription drugs and illicit drugs.

Clinicians should avoid prescribing opioid pain medication and benzodiazepines concurrently whenever possible. Clinicians should offer or arrange evidence-based treatment usually medication-assisted treatment with buprenorphine or methadone in combination with behavioral therapies for patients with opioid use disorder. Open Table in a new window. Conversion from morphine or equivalent to fentanyl transdermal :. Transdermal fentanyl is NOT recommended for breakthrough or unstable pain requiring frequent dosage adjustments.

Do not apply any external heat to patch; heat may increase absorption and increase risk of overdose. Augment around-the-clock scheduled opioid doses with PRN doses of short-acting opioids for acute exacerbation of chronic pain. Consider increasing hour scheduled opioid therapy if more than 4 breakthrough episodes occur in a day. After initiation and titration, the initial clinical efficacy may gradually decline. Then higher doses may have undesirable side-effects, and rotation can be considered. Change in clinical status requires different pharmacokinetics eg, renal insufficiency or hepatic dysfunction.

Specific mechanisms by which it improves overall response is unknown; likely from large individual variation to different agents and the phenomenon of incomplete cross-tolerance. Equianalgesic dose defined as the dose in steady state providing the same analgesic response. This has been standardized to 10 mg of parental morphine in most studies. First equianalgesic dose table published more than 40 years ago, and remain with little variation.

Major organ dysfunction, particularly renal and hepatic impairment, but also adrenal insufficiency, hypothyroidism, and abnormal levels of protein binding. Most trials were short term trials of acute postoperative pain or in cancer pain with low dose opioids. All new treatment should be considered a trial until it is found to be analgesically effective with acceptable side-effect profile. Conversion from oral or transdermal to parenteral route in more rapid analgesic effects. What should be considered when prescribing opioid equivalents?

Overview See the list below: A thorough pain assessment is vital to the initial evaluation of a patient and must be performed to guide treatment decisions. Immediate-release opioids are recommended for breakthrough pain. Most data are reported for opioid-tolerant patients so must be used with caution. The wide variation among individuals is multifactorial and poorly understood.

Opioids may be used, but long-acting formulations are recommended in place of prn dosing. Select formulation based on response, adverse effects, and Opiates in order of strength conditions. Reassess efficacy and adverse effects at 60 Opiates in order of strength.
