| 18. Black Box Warning | GI bleeding, CV events, ulcer risk | GI bleeding, CV events, ulcer risk |
| 19. Drug Interactions | Warfarin, lithium, diuretics, ACE inhibitors | Warfarin, lithium, diuretics, methotrexate |
| 20. Cost/Availability | Widely available, inexpensive (OTC and Rx) | Rx only; less commonly used, more expensive |
📌 Indications
| Naproxen | Sulindac |
|---|---|
| – Osteoarthritis | – Osteoarthritis |
| – Rheumatoid arthritis | – Rheumatoid arthritis |
| – Ankylosing spondylitis | – Ankylosing spondylitis |
| – Tendinitis, bursitis | – Bursitis |
| – Gout flares | – Gout flares |
| – Dysmenorrhea | – Familial adenomatous polyposis (FAP) (off-label) |
| – Mild to moderate pain, fever | – Pain and inflammation |
🚫 Contraindications
| Naproxen | Sulindac |
|---|---|
| – Hypersensitivity to naproxen or other NSAIDs | – Hypersensitivity to sulindac or NSAIDs |
| – History of GI bleeding or ulcers | – History of GI bleeding or perforation |
| – Severe heart failure or recent cardiac surgery | – Severe cardiovascular disease |
| – Advanced renal disease | – Severe hepatic impairment |
| – Active peptic ulcer disease | – NSAID-induced asthma or anaphylaxis |
💊 Dosage (Adults)
| Naproxen | Sulindac |
|---|---|
| Initial: 250–500 mg twice daily | 150–200 mg twice daily |
| Max: 1500 mg/day (short-term use) | Max: 400 mg/day |
⚠️ Warning Signs / When to Stop the Drug
| Common to Both NSAIDs |
|---|
| – Severe stomach pain, black or bloody stools (GI bleeding) |
| – Chest pain, shortness of breath (heart attack or stroke symptoms) |
| – Swelling of face or limbs, signs of allergic reaction |
| – Unusual fatigue, dark urine, yellowing of skin or eyes (liver problems) |
| – Sudden weight gain, edema, decreased urine output (kidney issues) |
| – Vision changes, headache, or dizziness (CNS effects) |
✅ Which One is Best and Safer?
| Criteria | Best Option | Explanation |
|---|---|---|
| GI Safety | Naproxen | Slightly lower GI complication rate when used with food |
| CV Safety | Naproxen | Associated with lower cardiovascular risk than sulindac |
| Kidney Risk | Similar risk | Both should be used cautiously in renal impairment |
| Hepatic Safety | Naproxen | Sulindac has higher liver metabolism burden; riskier in liver dysfunction |
| Pain Relief Speed | Naproxen | Slightly faster onset in pain relief |
| Availability/Cost | Naproxen | Widely available over-the-counter and cheaper |
| Special Indications | Sulindac | Better for familial adenomatous polyposis (FAP) |
Conclusion: ✅ Naproxen is generally safer and more versatile for most people due to its better cardiovascular profile, fewer hepatic concerns, lower GI risk, and availability. However, Sulindac may be chosen in specific conditions like FAP or when naproxen is not tolerated.
