Warnings While Using This Medicine:
- Make sure your doctor knows if you are pregnant, planning to become pregnant, or breastfeeding. Tell your doctor if you have kidney disease or liver disease.
- Insulin lispro starts to work faster than some other types of insulin, and its effects do not last as long. It should act more like the insulin your body would normally produce. Because the effects of insulin lispro are short-acting, your doctor may also prescribe a longer-acting insulin for you to use.
- Never share insulin pens or cartridges with others under any circumstances. It is not safe for one pen to be used for more than one person. Sharing needles or pens can result in transmission of hepatitis viruses, HIV, or other blood-borne illnesses.
- Follow the special diet and use the correct dose of insulin that your doctor orders. Diet, exercise, medicine, and checking your blood sugar are important to control your diabetes.
- You may sometimes have low blood sugar while you are using insulin. This is more likely if you miss a meal, exercise for a long time, or drink alcohol.
- If your blood sugar gets too low, you may feel weak, drowsy, confused, anxious, or very hungry. You may also sweat, shake, or have blurred vision, a fast heartbeat, or a headache that will not go away. If you have symptoms of low blood sugar (hypoglycemia), check your blood sugar. If your blood sugar is 70 mg/dL (milligrams per deciliter) or below, do one of the following: Drink 4 ounces (one-half cup) of fruit juice, or eat 5 to 6 pieces of hard candy, or take 2 to 3 glucose tablets. Recheck your blood sugar 15 minutes later. If your blood sugar goes above 70 mg/dL, eat a snack or a meal. If your blood sugar is still below 70 mg/dL, drink one-half cup juice, or eat 5 to 6 pieces of candy, or take 2 to 3 glucose tablets. Carry candy or some type of sugar with you at all times, especially if you are away from home. You can take this if you feel that your blood sugar is too low, even if you do not have a blood glucose meter. Always carefully follow your doctor's instructions about how to treat your low blood sugar. Learn what to do if your blood sugar gets too low. Teach friends, coworkers, and family members what they can do to help if you have low blood sugar.
