Drug interactions
Gliclazide + Nebivolol
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Overview
Beta-blockers can enhance hypoglycemia and mask adrenergic warning signs (e.g., tachycardia, tremor); risk is lower with beta1-selective agents like nebivolol but not absent.
Mechanism of action
Pharmacodynamic: beta-adrenergic blockade reduces hepatic glycogenolysis/gluconeogenesis and blunts sympathetic symptoms of hypoglycemia.
Clinical management
Use with caution; intensify glucose monitoring when initiating or adjusting doses; educate patients to recognize neuroglycopenic symptoms and sweating; consider sulfonylurea dose reduction if hypoglycemia occurs.
