Concurrent use of other NSAIDs, salicylate drugs (e.g., aspirin or diflunisal), triamterene, or pemetrexed
Fertility issues or ongoing fertility evaluation
Pregnancy, planned pregnancy, or suspected pregnancy. This medication may harm an unborn baby if taken after 20 weeks of gestation. If you are between 20 and 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.
To ensure your safety, it is crucial to disclose all your medications, including prescription and over-the-counter (OTC) drugs, natural products, and vitamins, as well as any health problems, to your doctor and pharmacist. Verify that it is safe to take this medication with your existing medications and health conditions. Never start, stop, or adjust the dose of any medication without consulting your doctor.
Precautions & Cautions
Until you understand how this medication affects you, avoid driving and other activities that require alertness. Be aware that you may experience easier bleeding, so it's crucial to be cautious and avoid injuries. To minimize the risk of bleeding, use a soft toothbrush and an electric razor for shaving.
This medication may interfere with certain laboratory tests, so it's vital to inform all your healthcare providers and laboratory personnel that you are taking this drug. If you plan to consume alcohol, discuss this with your doctor first. Similarly, if you smoke, consult with your doctor about the potential risks. Long-term use of this medication may require regular blood tests, so be sure to follow your doctor's recommendations.
There is a risk of developing high blood pressure with medications like this one. Ensure that your blood pressure is monitored as advised by your doctor. If you have asthma, consult with your doctor, as you may be more sensitive to this medication.
The use of drugs like this one can increase the risk of heart failure. If you already have heart failure, the risk of heart attack, hospitalization for heart failure, and death may be higher. Discuss these risks with your doctor. Additionally, people who have had a recent heart attack may have a higher risk of heart attack and heart-related death when taking this medication. There is also an increased risk of death in the year following a heart attack compared to those not taking this medication. Talk to your doctor about these risks.
If you are taking aspirin to prevent heart attacks, inform your doctor, as this may affect your treatment plan. Certain conditions, such as depression, mood problems, seizures, and Parkinson's disease, may worsen with this medication. If you have any of these conditions and notice your symptoms worsening, notify your doctor promptly.
If you are 65 or older, use this medication with caution, as you may be more susceptible to side effects. Women of childbearing age should be aware that NSAIDs like this medication may affect ovulation, potentially impacting fertility. However, this effect is reversible when the medication is stopped. Discuss any concerns with your doctor.
Finally, if you are breastfeeding, consult with your doctor to discuss any potential risks to your baby.

Special Patient Groups
Pregnancy
Avoid use during pregnancy, especially in the third trimester. Use in the first and second trimesters should only be if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
Indomethacin is excreted in breast milk. Due to potential for serious adverse reactions in nursing infants (e.g., CNS effects, GI bleeding, renal effects), use is generally not recommended. A safer alternative NSAID may be preferred.
Pediatric Use
Safety and efficacy have not been established for children under 14 years of age for inflammatory conditions. Oral capsules are not indicated for patent ductus arteriosus (PDA) closure in neonates (IV formulation is used for this specific indication).
Geriatric Use
Use with caution. Elderly patients are at higher risk for serious adverse events, particularly GI bleeding, cardiovascular events, and renal impairment. Start with the lowest effective dose and monitor closely for adverse effects.
Clinical Information
Clinical Pearls
- Indomethacin is a potent NSAID with a higher incidence of CNS side effects (e.g., headache, dizziness, confusion) compared to other NSAIDs.
- It is particularly effective for acute gouty arthritis and acute painful shoulder (bursitis/tendinitis).
- Due to its side effect profile, it is often reserved for patients who have not responded to other NSAIDs or for specific indications like gout.
- Always take with food, milk, or antacids to minimize GI irritation.
- Patients should be advised to report any signs of bleeding, severe stomach pain, or unusual headaches immediately.
- Avoid in patients with a history of aspirin-exacerbated respiratory disease (asthma, rhinitis with nasal polyps) due to risk of severe bronchospasm.
Alternative Therapies
- Other NSAIDs (e.g., Ibuprofen, Naproxen, Diclofenac, Celecoxib)
- Acetaminophen (for pain/fever, no anti-inflammatory effect)
- Corticosteroids (for severe inflammation, short-term use)
- Colchicine (for acute gout)
- Allopurinol/Febuxostat (for chronic gout prophylaxis)
- Disease-modifying antirheumatic drugs (DMARDs) for chronic inflammatory conditions like RA or AS.
