Summary
Rectally administered aspirin is absorbed systemically and can potentiate the glucose-lowering action of gliclazide at anti-inflammatory doses. Hypoglycemia is the main concern, especially in frail or elderly patients.
What this interaction means in plain words
Aspirin rectal and Gliclazide can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Salicylates have intrinsic hypoglycemic activity and may compete for protein binding, producing additive effects with sulfonylureas.
What to do
Monitor blood glucose during repeated or high-dose use and lower the gliclazide dose if glucose falls. Educate the patient on recognizing hypoglycemia.
