Moderate
Acetylsalicylic acid × Glibenclamide
Antiplatelet agents (low dose) / NSAIDs (analgesic dose)×Oral hypoglycemic agents. Sulfonylureas
Mechanism
High aspirin doses displace glibenclamide from albumin binding and suppress hepatic gluconeogenesis. Hypoglycaemia risk at aspirin doses above 3 g/day.
Symptoms
Sweating, tremor, hunger, tachycardia, confusion. Severe cases: seizures and coma. Symptoms appear 1–2 days after starting high aspirin doses.
Management
Cardioprotective aspirin doses (75–100 mg) are acceptable without adjustment. At high doses, monitor glucose 4 times daily in the first week; reduce glibenclamide if needed.
