Summary

Tolmetin is an NSAID that inhibits platelet function and can injure the gastric mucosa, while dabigatran is an oral direct thrombin inhibitor. Taken together they raise the risk of clinically significant bleeding, especially from the gastrointestinal tract.

What this interaction means in plain words

Dabigatran and Tolmetin 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.

Evidence level: High

Why it happens

Additive pharmacodynamic effects: NSAID-induced platelet inhibition and mucosal injury plus thrombin inhibition by dabigatran.

What to do

Avoid the combination where possible and use a non-NSAID analgesic such as paracetamol. If it cannot be avoided, use the shortest NSAID course, consider gastroprotection, and monitor for bleeding and falling hemoglobin.

What to ask your pharmacist
