You should not use Lantus if you are having an episode of hypoglycemia (low blood sugar), or if you are in a state of diabetic ketoacidosis (call your doctor for treatment).
Never share a Lantus injection pen or cartridge with another person. Sharing injection pens or cartridges can allow disease such as hepatitis or HIV to pass from one person to another.
Not all insulin glargine brands are equal in dosing. Follow your doctor’s instructions when changing from one brand to another. If there are any changes in the brand, strength, or type of insulin you use, your dosage needs may change.
Lantus is only part of a complete program of treatment that may also include diet, exercise, weight control, foot care, eye care, dental care, and testing your blood sugar. Follow your diet, medication, and exercise routines very closely. Changing any of these factors can affect your blood sugar levels.
