• Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues: Consider a lower dosage of insulin or an insulin secretagogue to reduce the risk of hypoglycemia when used concomitantly with XIGDUO XR.
Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues Insulin and insulin secretagogues (e.g., sulfonylureas) are known to cause hypoglycemia.
XIGDUO XR may increase the risk of hypoglycemia when combined with insulin and/or an insulin secretagogue [see Adverse Reactions (6.1) ] .
The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogues) or insulin.
Insulin or Insulin Secretagogues Clinical Impact The risk of hypoglycemia may be increased when XIGDUO XR is used concomitantly with insulin or insulin secretagogues (e.g., sulfonylurea) [see Warnings and Precautions (5.5) ].

• Macrovascular Outcomes: No clinical studies establishing conclusive evidence of macrovascular risk reduction with glimepiride tablets or any other antidiabetic drug.
Although only one drug in the sulfonylurea class (tolbutamide) was included in this study, it is prudent from a safety standpoint to consider that this warning may also apply to other oral hypoglycemic drugs in this class, in view of their close similarities in mode of action and chemical structure.
The following are examples of medications that may increase the glucose-lowering effect of sulfonylureas including glimepiride, increasing the susceptibility to and/or intensity of hypoglycemia: oral anti-diabetic medications, pramlintide acetate, insulin, angiotensin converting enzyme (ACE) inhibitors, H 2 receptor antagonists, fibrates, propoxyphene, pentoxifylline,…
The following are examples of medications that may reduce the glucose-lowering effect of sulfonylureas including glimepiride, leading to worsening glycemic control: danazol, glucagon, somatropin, protease inhibitors, atypical antipsychotic medications (e.g., olanzapine and clozapine), barbiturates, diazoxide, laxatives, rifampin, thiazides and other diuretics,…
Both acute and chronic alcohol intake may potentiate or weaken the glucose-lowering action of glimepiride in an unpredictable fashion.
