Name two or more medications in any question and Osler automatically resolves them via RxNorm, pulls the known interactions and grades their severity — no separate tool, no form to fill.
What do the sources say about ibuprofen with warfarin?
Checked automatically — no separate tool, no form
The problem
Traditional interaction checking is a separate tool with a separate form — which makes it the step that gets skipped under time pressure.
Question in one window, interaction checker in another. Every context switch is a chance the check never happens at all.
Classic checkers want exact drug names typed into exact fields. Clinical questions don’t arrive that way.
When trivial and dangerous interactions look the same in a flat list, alert fatigue buries the one that matters.
Automatic detection
Name two or more drugs anywhere in a question and Osler detects them automatically, resolves each to a precise concept via RxNorm — the US National Library of Medicine’s drug terminology — and pulls the known interactions.
Your question
What do the sources say about ibuprofen with warfarin?
Severity triage
Every interaction is normalized to high, moderate or low severity. High-severity interactions are promoted to the top of the sources with a red warning banner — and they are never trimmed from the results.
Interactions found · 3
Simvastatin + Amlodipine
Raised simvastatin exposure — myopathy risk
Lisinopril + Metformin
May enhance the glucose-lowering effect
Warfarin + Ibuprofen
Serious gastrointestinal bleeding risk
Normalized to high · moderate · low — the serious one leads
In context
The interaction result sits inside the same cited answer as the guideline recommendations and drug labels it relates to — one conversation and one evidence trail, instead of findings scattered across tools.
One cited answer
Warfarin labels list NSAIDs among the drugs that raise bleeding risk1; reviews quantify the added risk of GI bleeding23 and describe how it is monitored4.
Interactions, guidelines and labels — one evidence trail
The same check, moved to where the question is actually asked.
Separate checker tool
With Osler
The interaction check follows your question — you never leave the conversation.
“Can I add ibuprofen for a patient on warfarin?” — a question, not a form.
Both drugs are detected in your phrasing and resolved to precise RxNorm concepts.
Known interactions come back normalized to high, moderate or low severity.
A high-severity interaction opens the answer with a red banner — before anything else.
