Increased hypoglycemic effect w/ miconazole; phenylbutazone; alcohol. Potentiation of blood glucose lowering effect & thus, in some instances, hypoglycemia may occur w/ other antidiabetic agents [eg, insulins, acarbose, biguanides (eg, metformin), thiazolidinediones, dipeptidyl peptidase-4 inhibitors, GLP-1 receptor agonists], β-blockers, fluconazole, ACE inhibitors (eg, captopril, enalapril), H
2-receptor antagonists, MAOIs, sulfonamides, clarithromycin & NSAIDs. Not recommended in combination w/ danazol. Increased blood glucose levels w/ chlorpromazine (high doses eg, >100 mg daily); ritodrine, salbutamol, terbutaline. Increased blood glucose levels w/ possible ketosis w/ glucocorticoids & tetracosactrin. Decreased exposure w/ St. John's wort prep. Risk of dysglycemia w/ fluoroquinolones. May lead to potentiation of anticoagulation during concurrent anticoagulant therapy eg, warfarin.
