Insulin lispro and insulin lispro protamine is a combination medicine used to improve blood sugar control in adults with diabetes mellitus. This medicine may be used for type 1 or type 2 diabetes.

Insulin lispro and insulin lispro protamine may also be used for purposes not listed in this medication guide.

Insulin lispro and insulin lispro protamine is given as an injection (shot) under your skin. You will be shown how to use injections at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles and syringes. Do not mix this medicine with any other insulin.

Use this medication within 15 minutes before eating a meal.

Choose a different area of skin in your injection area each time you use this medicine. Do not inject into the same place two times in a row.

Never share an injection pen with another person. Sharing injection pens can allow disease such as hepatitis or HIV to pass from one person to another.

Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, confusion, irritability, dizziness, or feeling shaky. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.

If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss.

Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your medication dose or schedule without your doctor's advice.

Insulin is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
