Humalog vials are used for:
Treating diabetes mellitus. Humalog vials are usually used with a longer-acting insulin or insulin pump therapy. In some patients, it may be used with a sulfonylurea antidiabetic instead of a longer-acting insulin.
Humalog vials are a fast-acting form of the hormone insulin. It works by helping your body to use sugar properly. This lowers the amount of glucose in the blood, which helps to treat diabetes.
Do NOT use Humalog vials if:

Contact your doctor or health care provider right away if any of these apply to you.

- Any change of insulin should be made cautiously and only under medical supervision. Changes in purity, strength, brand (manufacturer), type (regular, NPH, lente), species (beef, pork, beef-pork, human), and/or method of manufacture may require a change in dose.
- Illness, especially with nausea and vomiting, may cause your insulin requirements to change. Even if you are not eating, you will still require insulin. You and your doctor should establish a sick day plan to use in case of illness. When you are sick, test your blood/urine frequently and call your doctor as instructed.
- Tell your doctor or dentist that you take Humalog vials before you receive any medical or dental care, emergency care, or surgery.

- Carry an ID card at all times that says you have diabetes.
- An insulin reaction resulting from low blood sugar levels (hypoglycemia) may occur if you take too much insulin, skip a meal, or exercise too much. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you more hungry. It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or nondiet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.
- Developing a fever or infection, eating significantly more than prescribed, or missing your dose of insulin may cause high blood sugar (hyperglycemia). High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, or have a fruit-like breath odor. If these symptoms occur, tell your doctor right away.
- Check with your doctor if you notice a depression in the skin or skin thickening at the injection site. You may need to change your injection technique.

- Use Humalog vials with caution in the ELDERLY; if low blood sugar occurs, it may be more difficult to recognize in these patients.
