Type 2 diabetes adverse events

This trial was not designed to evaluate the relative safety between BASAGLAR and Lantus products (approved in the US or outside the US), and comparator adverse event rates are not an adequate basis for comparison of rates between the products.

Hypoglycemia was the most commonly observed adverse reaction in patients using insulin, including BASAGLAR. Hypoglycemia was defined as blood glucose ≤3.9 mmol/L (≤70 mg/dL) or a sign or symptom associated with hypoglycemia. Severe symptomatic hypoglycemia was defined as an event with symptoms consistent with hypoglycemia that required assistance of another person, and was associated with either blood glucose levels below 50 mg/dL or prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration.1,4

Rates of reported hypoglycemia depend upon the definition of hypoglycemia used, diabetes type, insulin dose, intensity of glucose control, background therapies, and other intrinsic and extrinsic factors. For these reasons, comparing rates of hypoglycemia in clinical trials for BASAGLAR with the incidence of hypoglycemia for other products may be misleading, and may not be representative of hypoglycemia rates that will occur in clinical practice.

Type 2 diabetes: adverse reactions occurring in ≥5% of adult patients treated with BASAGLAR® (insulin glargine injection) 100 units/mL or Lantus products* over 24 weeks of treatment1,5

*Approved in the US or outside the US.

Infections other than nasopharyngitis or upper respiratory tract infection.

Infections were a category of treatment-emergent adverse events that were reported during the 24-week trial and included events such as influenza, urinary tract infection, bronchitis, gastroenteritis, and sinusitis. Excluded were nasopharyngitis and upper respiratory tract infection.6

OAMS=oral anti-diabetic medications.

Indications and Important Safety Information

BASAGLAR is indicated to improve glycemic control in adults and pediatric patients with type 1 diabetes mellitus and in adults with type 2 diabetes mellitus.


BASAGLAR is not recommended for the treatment of diabetic ketoacidosis.


BASAGLAR is contraindicated during episodes of hypoglycemia, and in patients with hypersensitivity to insulin glargine or one of its excipients.


BASAGLAR KwikPen® must never be shared between patients, even if the needle is changed. Sharing poses a risk of transmission of blood borne pathogens.

Changes in insulin strength, manufacturer, type, or method of administration may affect glycemic control and predispose to hypoglycemia or hyperglycemia. These changes should be made cautiously and only under close medical supervision, and the frequency of blood glucose monitoring should be increased. For patients with type 2 diabetes, dosage adjustments of concomitant anti-diabetic products may be needed.

Hypoglycemia is the most common adverse reaction associated with insulins, including BASAGLAR. Severe hypoglycemia can cause seizures, may be life-threatening, or cause death.

Accidental mix-ups between another insulin glargine product (100 units/mL) and other insulins, particularly rapid-acting insulins, have been reported. To avoid medication errors between BASAGLAR and other insulins, instruct patients to always check the insulin label before each injection.

Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulin products, including BASAGLAR. If hypersensitivity reactions occur, discontinue BASAGLAR; treat per standard of care and monitor until symptoms and signs resolve. BASAGLAR is contraindicated in patients who have had hypersensitivity reactions to insulin glargine or one of the excipients.

All insulin products, including BASAGLAR, cause a shift in potassium from the extracellular to intracellular space, possibly leading to hypokalemia. Untreated hypokalemia may cause respiratory paralysis, ventricular arrhythmia, and death. Monitor potassium levels in patients at risk for hypokalemia if indicated.

Thiazolidinediones (TZDs), which are peroxisome proliferator-activated receptor (PPAR)-gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin. Fluid retention may lead to or exacerbate heart failure. These patients should be observed for signs and symptoms of heart failure. If heart failure occurs, dosage reduction or discontinuation of TZD must be considered.


Adverse reactions commonly associated with insulin glargine products (5% or greater incidence) are: hypoglycemia, allergic reactions, injection site reaction, lipodystrophy, pruritus, rash, edema, and weight gain.


Certain drugs may affect glucose metabolism, requiring insulin dose adjustment and close monitoring of blood glucose. The signs and symptoms of hypoglycemia may be blunted when beta-blockers, clonidine, guanethidine, and reserpine are co-administered with BASAGLAR.
