Do not share your Insulin lispro with another person. This includes any pens, cartridge devices, needles, or syringes, even if the needle has been changed. Sharing may pass infections from one person to another. This includes infections you may not know you have.
Low blood sugar may happen with insulin lispro. Very low blood sugar can lead to seizures, passing out, long lasting brain damage, and sometimes death.
Low blood potassium may also happen with insulin lispro. If not treated, this can lead to a heartbeat that is not normal, very bad breathing problems, and sometimes death.
It may be harder to control blood sugar during times of stress such as fever, infection, injury, or surgery. A change in physical activity, exercise, or diet may also affect blood sugar.
Do not drive if your blood sugar has been low. There is a greater chance of you having a crash.
Talk with your doctor before you drink alcohol or take products that have alcohol in them.
Before taking this medicine
You should not use insulin lispro if you are allergic to it, or if you are having an episode of hypoglycemia (low blood sugar).
Insulin lispro should not be given to a child younger than 3 years old. Insulin lispro should not be used to treat type 2 diabetes in a child of any age.
To make sure Insulin lispro is safe for you, tell your doctor if you have ever had:
liver or kidney disease;
heart problems; or
low levels of potassium in your blood (hypokalemia).
Tell your doctor if you also take medicine that contains pioglitazone or rosiglitazone. Taking certain oral diabetes medicines while you are using insulin lispro may increase your risk of serious heart problems.
Tell your doctor if you are pregnant or breastfeeding.
Follow your doctor's instructions about using insulin lispro if you are pregnant or you become pregnant. Controlling diabetes is very important during pregnancy, and having high blood sugar may cause complications in both the mother and the baby.
