What is the most important information I should know about insulin glargine (Lantus, Lantus OptiClik Cartridge, Lantus Solostar Pen)?
Take care not to let your blood sugar get too low. Low blood sugar (hypoglycemia) can occur if you skip a meal, exercise too long, drink alcohol, or are under stress. Symptoms include headache, hunger, weakness, sweating, tremors, irritability, or trouble concentrating. Carry hard candy or glucose tablets with you in case you have low blood sugar. Other sugar sources include orange juice and milk. Be sure your family and close friends know how to help you in an emergency.
Also watch for signs of blood sugar that is too high (hyperglycemia). These symptoms include increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss. Your blood sugar will need to be checked often, and you may need to adjust your insulin glargine dose.
Insulin glargine 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.
