Nursing implications

Nursing assessment

  • Patients who have asthma, aspirin-induced allergy, and nasal polyps are at increased risk for developing hypersensitivity reactions. Monitor for rhinitis, asthma, and urticaria.
  • Assess for rash periodically during therapy. May cause Stevens-Johnson syndrome. Discontinue therapy if severe or if accompanied with fever, general malaise, fatigue, muscle or joint aches, blisters, oral lesions, conjunctivitis, hepatitis, and/or eosinophilia.
  • Osteoarthritis/Rheumatoid Arthritis: Assess pain and range of movement before and 1–2 hr after administration.
  • Pain: Assess location, duration, and intensity of the pain before and 60 min after administration.
  • Lab Test Considerations: May cause ↓ hemoglobin, hematocrit, leukocyte, and platelet counts.
    • Monitor liver function tests within 8 wk of initiating etodolac therapy and periodically during therapy. May cause ↑ serum alkaline phosphatase, LDH, AST, and ALT concentrations.
    • Monitor BUN, serum creatinine, and electrolytes periodically during therapy. May cause ↑ BUN, serum creatinine, and electrolyte concentrations and ↓ urine electrolyte concentrations.
    • May cause ↓ serum and ↑ urine uric acid concentrations.

Potential Nursing Diagnoses

Acute pain (Indications)
Impaired physical mobility (Indications)


  • Do not confuse Lodine (etodolac) with codeine or iodine.
    • Administration in higher-than-recommended doses does not provide increased effectiveness but may cause increased side effects.
  • Use lowest effective dose for shortest period of time.
  • Oral: For rapid initial effect, administer 30 min before or 2 hr after meals. May be administered with food, milk, or antacids containing aluminum or magnesium to decrease GI irritation.
    • Do not break, crush, or chew extended-release tablets.

Patient/Family Teaching

  • Advise patients to take etodolac with a full glass of water and to remain in an upright position for 15–30 min after administration.
  • Instruct patient to take medication as directed. Take missed doses as soon as possible within 1–2 hr if taking twice/day, or unless almost time for next dose if taking more than twice/day. Do not double doses.
  • Etodolac may occasionally cause drowsiness or dizziness. Advise patient to avoid driving or other activities requiring alertness until response to the medication is known.
  • Caution patient to avoid the concurrent use of alcohol, aspirin, acetaminophen, NSAIDs, or other OTC medications without consultation with health care professional.
  • Advise patient to inform health care professional of medication regimen before treatment or surgery.
  • Advise patient to consult health care professional if rash, itching, visual disturbances, tinnitus, weight gain, edema, black stools, persistent headache, or influenza-like syndrome (chills, fever, muscle aches, pain) occurs.

Evaluation/Desired Outcomes

  • Decreased severity of pain.
  • Improved joint mobility. Patients who do not respond to one NSAID may respond to another. May require 2 wk or more for maximum anti-inflammatory effects.
