Summary
Combining two NSAIDs increases the risk of gastrointestinal ulceration and bleeding, renal injury and hyperkalemia without improving pain control.
What this interaction means in plain words
Sulindac 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.
Sulindac belongs to Musculoskeletal; Tolmetin belongs to Musculoskeletal.
Why it happens
Both inhibit cyclooxygenase, giving additive gastric mucosal damage, platelet inhibition and renal prostaglandin suppression.
What to do
Avoid combining the two; use a single NSAID at the lowest effective dose. Add gastroprotection if NSAID therapy is needed in a high-risk patient.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
