Clinical Summaries

Plain-English explanations with direct BNF and NICE references. Copy and share with the GP to support prescribing decisions.

Generated summary
Warfarin + Naproxen: NSAIDs significantly potentiate the anticoagulant effect of warfarin, increasing the risk of gastrointestinal bleeding. This combination should be avoided where possible. If co-prescription is unavoidable, consider gastroprotection and increased INR monitoring.
