Summary

Tenecteplase is a fibrinolytic that markedly increases bleeding risk, and naproxen impairs platelet function and can injure the gastric mucosa. Combined use raises the likelihood of serious hemorrhage, including gastrointestinal and intracranial bleeding.

What this interaction means in plain words

Naproxen and Tenecteplase can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Naproxen belongs to Musculoskeletal; Tenecteplase belongs to Cardiovascular.

Evidence level: Moderate

Why it happens

Additive effects of fibrinolysis and NSAID-induced reversible platelet inhibition and mucosal injury.

What to do

Avoid starting NSAIDs around thrombolysis unless clearly needed, and monitor closely for bleeding. Use paracetamol for analgesia where possible.
