Contraindications for Prescribing NSAIDs (Non-Steroidal Anti-Inflammatory Drugs)

Overview

NSAIDs (such as ibuprofen, diclofenac, naproxen, indomethacin, etc.) are widely used for pain, inflammation, and fever, but they have important contraindications and situations where they should be avoided or used only with great caution.

Major (Often Considered Absolute) Contraindications

• Allergy or hypersensitivity to NSAIDs or aspirin

  • Previous anaphylaxis, angioedema, severe rash, or severe reactions after NSAIDs or aspirin.

• Aspirin/NSAID-exacerbated respiratory disease

  • History of asthma, nasal polyps, or rhinosinusitis with bronchospasm or severe wheeze triggered by aspirin or NSAIDs.

• Active or recent significant gastrointestinal (GI) ulcer or bleeding

  • Active peptic ulcer disease.
  • Recent upper GI bleeding or perforation suspected to be related to NSAIDs.

• Severe heart failure

  • Especially decompensated or uncontrolled heart failure, because NSAIDs can cause fluid retention and worsen heart function.

• Severe kidney (renal) impairment

  • Advanced chronic kidney disease (e.g., significantly reduced eGFR) or acute kidney injury.

• Severe liver disease

  • Advanced cirrhosis or significant hepatic dysfunction with bleeding risk or renal vulnerability.

• Perioperative use in coronary artery bypass graft (CABG) surgery

  • Certain NSAIDs (especially some COX-2 selective agents) are specifically contraindicated immediately before or after CABG due to cardiovascular risk.

• Known NSAID-induced serious skin reactions

  • History of severe skin reactions such as Stevens–Johnson syndrome or toxic epidermal necrolysis with NSAIDs.

• Late pregnancy (especially 3rd trimester)

  • Risk of premature closure of the fetal ductus arteriosus, fetal kidney problems, and reduced amniotic fluid.

Relative Contraindications / Situations Requiring Great Caution

In these conditions, doctors often either avoid NSAIDs or use them only if the potential benefit clearly outweighs the risk, with close monitoring.

• History of peptic ulcer disease or GI bleeding

  • Even if not currently active, especially in older adults or those with >1 risk factor.

• Concomitant use of medicines that increase bleeding or GI risk

  • Anticoagulants (e.g., warfarin, DOACs), antiplatelets (e.g., aspirin, clopidogrel).
  • Systemic corticosteroids or SSRIs (can increase GI bleeding risk).

• Mild to moderate renal impairment

  • Especially in dehydration, older age, or with other nephrotoxic drugs (e.g., ACE inhibitors, ARBs, diuretics, certain antibiotics).

• Hypertension and cardiovascular disease

  • Uncontrolled hypertension, ischemic heart disease, prior stroke, or peripheral arterial disease.
  • COX-2 selective NSAIDs and high-dose traditional NSAIDs may increase cardiovascular and thrombotic risk.

• Fluid retention states

  • Heart failure (even mild), edema, nephrotic syndrome, or other conditions where extra fluid is harmful.

• Inflammatory bowel disease (IBD)

  • Ulcerative colitis or Crohn’s disease may flare with NSAID use in some people.

• Asthma without clear history regarding NSAIDs

  • Caution in patients with asthma where sensitivity to NSAIDs is unknown, especially if there are nasal polyps or chronic rhinosinusitis.

• Older age (e.g., >65 years)

  • Higher risk of GI bleeding, kidney injury, and cardiovascular events.

• Mild to moderate liver disease or increased bleeding tendency

  • NSAIDs can affect platelet function and increase bleeding risk.

Special Populations

• Pregnancy

  • Generally avoided especially in the 3rd trimester; early pregnancy use also requires caution and individual risk–benefit assessment.

• Breastfeeding

  • Some NSAIDs are considered relatively safer than others; choice and duration should be guided by a doctor.

• Children

  • Dosing is weight-based, and some NSAIDs are not recommended below certain ages; professional guidance is essential.

Key Points to Discuss with a Doctor Before Using NSAIDs

• Any history of allergy or breathing problems with painkillers or aspirin.
• History of ulcers, indigestion, black or bloody stools, or vomiting blood.
• Existing heart, kidney, liver disease, or high blood pressure.
• Current medications (especially blood thinners, blood pressure medicines, steroids, or other painkillers).
• Pregnancy status, plans for pregnancy, or breastfeeding.
• Any chronic conditions such as asthma, IBD, or autoimmune diseases.

Clinical Use Note

The decision to use or avoid NSAIDs, and the choice of specific agent, dose, and duration, must always be individualized by a licensed clinician based on overall risk–benefit assessment, alternatives, and monitoring plans.
