Before Using This Medicine
It is essential to inform your doctor about the following conditions to ensure safe treatment:
Any allergies you have, including allergies to this medication, its components, or other substances, such as foods or drugs. Describe the allergic reaction and its symptoms.
Allergies to aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen.
A history of nasal polyps or swelling of the mouth, face, lips, tongue, or throat, unusual hoarseness, or breathing difficulties after taking aspirin or NSAIDs.
Certain health conditions, including:
+ Gastrointestinal (GI) bleeding or kidney problems.
+ Heart failure (weak heart) or a recent heart attack.
Concurrent use of other NSAIDs, salicylate drugs like aspirin, or pemetrexed.
Use of phenylbutazone.
Fertility issues or ongoing fertility evaluation.
Pregnancy, planned pregnancy, or pregnancy occurrence while taking this medication. This drug may harm an unborn baby if taken at 20 weeks or later in pregnancy. If you are between 20 to 30 weeks pregnant, only take this medication under your doctor's guidance. Do not take this medication if you are more than 30 weeks pregnant.
This list is not exhaustive, and it is crucial to discuss all your medications (prescription, over-the-counter, natural products, and vitamins) and health conditions with your doctor and pharmacist. Verify that it is safe to take this medication with your existing treatments and health issues. Never start, stop, or modify the dosage of any medication without consulting your doctor.
Precautions & Cautions
This medication may interfere with certain laboratory tests, so it is crucial to notify all your healthcare providers and lab personnel that you are taking this drug. Additionally, medications like this one have been associated with high blood pressure, so your doctor may advise you to have your blood pressure checked regularly.
Before consuming alcohol, discuss the potential risks with your doctor. If you smoke, you should also talk to your doctor about the potential interactions. It is vital to follow your doctor's instructions regarding dosage and duration of treatment. Taking more than the prescribed amount or using this medication for longer than recommended may increase your risk of severe side effects.
If you have asthma, consult your doctor before taking this medication, as you may be more sensitive to its effects. This medication can also increase your risk of bleeding, so it is essential to be cautious and avoid injuries. To minimize this risk, use a soft toothbrush and an electric razor.
The use of medications like this one has been linked to an increased risk of heart failure. If you already have heart failure, your risk of heart attack, hospitalization for heart failure, and death may be higher. Discuss these potential risks with your doctor. Furthermore, people who have had a recent heart attack may have a higher risk of heart attack and heart-related death when taking medications like this one. In fact, studies have shown that individuals taking these medications after a first heart attack were more likely to die within the following year compared to those not taking these medications.
If you are taking aspirin to prevent heart attacks, consult your doctor about potential interactions. Older adults (65 years and older) should use this medication with caution, as they may be more susceptible to side effects.
Medications like this one, which are classified as NSAIDs, may affect ovulation (egg release) and potentially impact fertility. However, this effect is typically reversible when the medication is stopped. If you are trying to conceive, discuss these potential risks with your doctor.
Finally, if you are breastfeeding, you should consult your doctor about the potential risks to your baby. Your doctor will help you weigh the benefits and risks of using this medication while breastfeeding.

Monitoring
Baseline Monitoring
Rationale: To establish baseline and monitor for anemia or other hematologic abnormalities, especially with long-term use.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and monitor for drug-induced hepatotoxicity.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and monitor for NSAID-induced acute kidney injury or worsening of pre-existing renal impairment.
Timing: Prior to initiation of therapy.
Rationale: NSAIDs can cause new onset hypertension or worsen pre-existing hypertension.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Periodically, especially in patients at risk for renal impairment (e.g., elderly, heart failure, diuretic use) or with long-term therapy.
Target: Within patient's normal range or stable.
Action Threshold: Significant increase in creatinine or decrease in eGFR; consider dose reduction or discontinuation.
Frequency: Periodically, especially with long-term therapy or if symptoms of liver dysfunction develop.
Target: Within normal limits.
Action Threshold: Significant elevation of transaminases (e.g., >3x ULN); consider discontinuation.
Frequency: Regularly, especially in hypertensive patients.
Target: Within target BP goals.
Action Threshold: Sustained elevation; consider alternative antihypertensive or NSAID discontinuation.
Frequency: Periodically with long-term therapy (e.g., >1 month).
Target: Within normal limits.
Action Threshold: Significant drop in hemoglobin/hematocrit (suggesting GI bleeding) or other cytopenias; investigate cause.
Symptom Monitoring
- Signs of gastrointestinal bleeding (e.g., black, tarry stools; coffee-ground vomit; severe abdominal pain)
- Symptoms of cardiovascular events (e.g., chest pain, shortness of breath, weakness on one side of the body, slurred speech)
- Signs of renal impairment (e.g., decreased urine output, swelling in ankles/feet)
- Symptoms of liver injury (e.g., fatigue, nausea, dark urine, jaundice, right upper quadrant tenderness)
- Signs of allergic reactions or severe skin reactions (e.g., rash, blistering, itching, swelling of face/throat)
- Unusual bruising or bleeding
- Persistent headache or vision changes
Special Patient Groups
Pregnancy
Avoid use during the third trimester of pregnancy due to the risk of premature closure of the fetal ductus arteriosus and fetal renal dysfunction. Use during the first and second trimesters should only be if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
Etodolac is excreted in breast milk in small amounts. Use with caution during breastfeeding. Monitor the infant for adverse effects such as drowsiness, poor feeding, or unusual irritability.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients under 18 years of age. Use is generally not recommended.
Geriatric Use
Elderly patients are at increased risk for serious adverse cardiovascular, gastrointestinal, and renal events. Use the lowest effective dose for the shortest duration possible. Monitor closely for adverse effects.
Clinical Information
Clinical Pearls
- Always advise patients to take Etodolac with food, milk, or an antacid to minimize gastrointestinal upset.
- Etodolac is not a substitute for aspirin for cardiovascular prophylaxis; it may actually interfere with aspirin's antiplatelet effect.
- Educate patients on the signs and symptoms of GI bleeding and cardiovascular events, emphasizing the importance of immediate medical attention if they occur.
- Consider alternative pain management strategies in patients with significant cardiovascular or gastrointestinal risk factors.
- For chronic use, periodic monitoring of renal function, liver enzymes, and blood pressure is crucial.
Alternative Therapies
- Other NSAIDs (e.g., ibuprofen, naproxen, celecoxib, diclofenac)
- Acetaminophen (for pain and fever, no anti-inflammatory effect)
- Opioid analgesics (for severe pain, different mechanism and side effect profile)
- Topical NSAIDs (for localized pain)
- Non-pharmacological therapies (e.g., physical therapy, heat/cold therapy, exercise, acupuncture)
