Insulin

If you're using Humalog with an external insulin pump, do not dilute it with another liquid or mix it with any other insulins.

What side effects may occur?

While side effects from insulin use are rare, allergic reactions or low blood sugar (sometimes called "an insulin reaction") may pose significant health risks. Your doctor should be notified if any of the following occur:

• Mild allergic reactions:
  Swelling, itching or redness at the injection site (usually disappears within a few days or weeks)

• More serious allergic reactions:
  Fast pulse, low blood pressure, perspiration, rash over the entire body, shortness of breath, shallow breathing, or wheezing

Other side effects are virtually eliminated when the correct dose of insulin is matched with the proper diet and level of physical activity. Low blood sugar may develop in poorly controlled or unstable diabetes. Consuming sugar or a sugar-containing product will usually correct the condition, which can be brought about by taking too much insulin, missing or delaying meals, exercising or working more than usual, an infection or illness, a change in the body's need for insulin, drug interactions, or consuming alcohol.

• Symptoms of low blood sugar include:
  Abnormal behavior, anxiety, blurred vision, cold sweat, confusion, depressed mood, dizziness, drowsiness, fatigue, headache, hunger, inability to concentrate, light-headedness, nausea, nervousness, personality changes, rapid heartbeat, restlessness, sleep disturbances, slurred speech, sweating, tingling in the hands, feet, lips, or tongue, tremor, unsteady movement

Contact your physician if these symptoms persist.

• Symptoms of more severe low blood sugar include:
  Coma, disorientation

Remember, too, the symptoms associated with an under-supply of insulin, which can be brought on by taking too little of it, overeating, or fever and infection.

• Symptoms of insufficient insulin include:
  Drowsiness, flushing, fruity breath, heavy breathing, loss of appetite, rapid pulse, thirst
