Interactions
Drug-Drug interaction
Concurrent use with aspirin may ↓ effectiveness.↑ adverse GI effects with aspirin, other NSAIDs, potassium supplements, corticosteroids, antiplatelet agents, or alcohol.Chronic use with acetaminophen may ↑ risk of adverse renal reactions.May ↓ effectiveness of diuretic or antihypertensive therapy.May ↑ serum lithium levels and ↑ risk of toxicity.↑ risk of toxicity from methotrexate.↑ risk of bleeding with cefotetan, cefoperazone, valproic acid, thrombolytics, antiplatelet agents, or anticoagulants.↑ risk of adverse hematologic reactions with antineoplastics or radiation therapy.May ↑ the risk of nephrotoxicity from cyclosporine.↑ risk of bleeding with arnica, chamomile, clove, dong quai, fever few, garlic, ginko, and Panax ginseng.Route/Dosage

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)
Implementation
- 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.
