Considerations for NSAID use

Australian and New Zealand College of Anaesthetists (ANZCA), 2020Felson, 2016

No single nonsteroidal anti-inflammatory drug (NSAID) has been shown to be more effective than any other, but some patients may respond better to one NSAID than to others. If a patient does not respond to the first NSAID, generally 1 or 2 other NSAIDs should be trialled to confirm nonresponse.

NSAIDs can cause significant gastrointestinal, cardiovascular and renal adverse effects, which are summarised in Significant cardiovascular, gastrointestinal and renal adverse effects of NSAIDs. The relative risk of individual adverse effects depends on the NSAID used and patient factors (see Choosing an NSAID). In general, the risk of harms increases with patient age, dose and duration of treatment.

Topical NSAIDs have minimal systemic absorption, so are considerably safer than oral NSAIDs; however, they may only be useful for superficial sources of musculoskeletal painDerry, 2016Derry, 2015.

Principles of prescribing NSAIDs for musculoskeletal pain are given in Principles of prescribing NSAIDs for musculoskeletal pain. NSAIDs (oral and topical) should be used cautiously or, in some cases, avoided in the following groups:

To reduce the need for oral NSAIDs, consider:

Assess the individual benefit–harm profile of an NSAID in each patient.

Avoid NSAIDs in patients with:

  • active peptic ulcer disease or gastrointestinal bleeding
  • a GFR of less than 30 mL/minute
  • cirrhosis
  • bone marrow impairment (eg haematological malignancy).

Avoid long-term use of NSAIDs in patients with a GFR of 30 to 60 mL/minute unless the patient has no other risk factors for acute kidney injury and there is no alternative treatment available.

If possible, avoid NSAIDs in patients:

  • with established cardiovascular disease (eg heart failure, stroke) or at high risk of cardiovascular disease
  • with an increased risk of gastrointestinal or cardiovascular toxicity
  • treated with systemic corticosteroids. Concurrent use significantly increases the risk of gastrointestinal toxicity, and NSAIDs are unlikely to have additional benefit [NB1].

Consider if an NSAID is appropriate for:

  • older people—assess the need for an NSAID carefully
  • patients taking other drugs that may cause a drug–drug interaction.

If prescribing an NSAID:

  • Choose an NSAID to trial based on patient factors
  • Use the minimum effective dose for the shortest time possible.
  • Do not use more than one NSAID at a time, except for coadministration with low-dose aspirin if it is clinically indicated for other reasons.
  • For patients with risk factors for increased gastrointestinal toxicity with an NSAID or who are likely to be treated with an NSAID long term, consider co-prescribing a PPI for prophylaxis and testing for Helicobacter pylori (see Patients who have an increased risk of gastrointestinal toxicity).
  • Encourage patients taking an NSAID long-term to address lifestyle -risk factors for gastrointestinal toxicity (eg tobacco smoking, obesity) and cardiovascular disease.
  • Monitor treatment response, adverse effects and the ongoing need for an NSAID. Do not continue NSAIDs if there is no benefit or treatment is harmful.
    • Children, especially those of preschool age, may not display obvious symptoms of gastrointestinal intolerance to NSAIDs. Less obvious symptoms, such as irritability or loss of appetite, may be the only clues to NSAID intolerance.
    • Pseudoporphyria (photosensitivity causing facial skin blisters and scarring) is a well-recognised adverse reaction to naproxen, which is described mainly in children. If this occurs, immediately stop naproxen.
  • Periodically consider a trial of dose tapering or treatment cessation.
Note:

GFR = glomerular filtration rate; NSAIDs = nonsteroidal anti-inflammatory drugs; PPI = proton pump inhibitor

NB1: In patients currently taking an NSAID who require a short course of systemic corticosteroid, consider withholding the NSAID while the patient is treated with the corticosteroid. In patients currently taking a systemic corticosteroid who require acute anti-inflammatory treatment, consider temporarily increasing the dose of the corticosteroid instead of using an NSAID.
