Summary
Salicylates at higher doses can enhance the glucose lowering effect of sulfonylureas and cause hypoglycemia. Low-dose aspirin rarely has this effect.
What this interaction means in plain words
Acetylsalicylic acid and Tolazamide 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.
Acetylsalicylic acid belongs to Musculoskeletal; Tolazamide belongs to Endocrine.
Why it happens
Salicylates displace sulfonylureas from protein binding, may reduce their renal clearance, and have intrinsic glucose lowering effects.
What to do
Monitor blood glucose when starting or stopping regular high-dose aspirin, and reduce the tolazamide dose if hypoglycemia occurs. Educate patients on hypoglycemia symptoms.
