What is the most important information I should know about insulin glargine?

Take care to keep your blood sugar from getting too low, causing hypoglycemia. Symptoms of low blood sugar may include headache, nausea, hunger, confusion, drowsiness, weakness, dizziness, blurred vision, fast heartbeat, sweating, tremor, or trouble concentrating. Carry a piece of non-dietetic hard candy or glucose tablets with you in case you have low blood sugar. Also 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, loss of appetite, increased urination, nausea, vomiting, drowsiness, dry skin, and dry mouth. Check your blood sugar levels and ask your doctor how to adjust your insulin doses if needed.

Never share an 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.

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.
