High bleeding risk combination. NSAIDs impair platelet function and can cause GI bleeding — this is amplified by anticoagulants. If your prescriber approves short-term NSAID use, take with food and use the lowest dose. Consider acetaminophen as a safer alternative for pain.
Higher risk for: elderly patients, those with liver disease, history of GI bleeding, concurrent use of multiple blood thinners, recent surgery, vitamin K intake changes, alcohol use, or low body weight.
HIGH bleeding risk: NSAIDs and anticoagulants together significantly increase the chance of serious bleeding. Watch for: unusual bruising, blood in urine (pink/red/brown), black tarry stools, vomiting blood or material that looks like coffee grounds, prolonged bleeding from cuts, frequent nosebleeds, or bleeding gums when combining Warfarin with Indomethacin. When to seek emergency help: Severe or uncontrollable bleeding, sudden severe headache, vision changes, difficulty speaking, coughing up blood, or abdominal pain with swelling. This combination should be used only when clearly necessary and under close medical supervision.
No urgent discussion needed, but keep your provider informed. Say: "I take Warfarin alongside Indomethacin — anything I should know?"
These medications are safe to take together at standard doses. Continue taking as prescribed and keep your pharmacist informed of your complete medication list.
