What are the possible side effects of insulin lispro?

• Rarely, people have allergic reactions to insulin. Seek emergency medical attention if you experience an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives).
• The side effects of insulin therapy result mostly from blood sugar levels that are either too high or too low. You should be familiar with the symptoms of both high and low blood sugar levels and know how to treat both conditions. Also, be sure your family and close friends know how to help you in an emergency.
• Low blood sugar may occur when too much insulin is used; when meals are missed or delayed; if you exercise more than usual; during illness, especially with vomiting or diarrhea; if you take other medications; after drinking alcohol; and in other situations.
• Hypoglycemia, or low blood sugar, has the following symptoms: shaking, headache, cold sweats, pale, cool skin, anxiety, and difficulty concentrating.
• Keep hard, sugary candy; chocolate; fruit juice; or glucose tablets on hand to treat episodes of low blood sugar.
• Increased blood sugar may occur if not enough insulin is used, if you eat significantly more food then usual, if you exercise less than usual, if you take other medications, if you have a fever or other illness, and in other situations.
• Hyperglycemia, or high blood sugar, has the following symptoms: increased thirst, increased hunger, and increased urination.
• Monitor your blood sugar levels and ask your doctor how to adjust your insulin doses if your blood sugar levels are too high.
• Side effects may also occur at the site of injection. If the area becomes thickened, hard, or pitted, talk to your doctor before injecting at that site again.
• Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.

What other drugs will affect insulin lispro?

• Many drugs can interact with insulin or affect your blood sugar levels. Do not take any other medicines, including prescription products or over-the-counter medicines or supplements without first talking to your doctor or pharmacist during treatment with insulin.

Where can I get more information?
