Humulin N vials

Humulin N vials are an intermediate-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 Humulin N vials if:
- you are allergic to any ingredient in Humulin N vials
- you are having an episode of low blood sugar
Contact your doctor or health care provider right away if any of these apply to you.

- Thiazolidinediones (eg, pioglitazone, rosiglitazone) because the risk of heart failure may be increased
- Corticosteroids (eg, prednisone), danazol, diuretics (eg, furosemide, hydrochlorothiazide), estrogen, hormonal contraceptives (eg, birth control pills), isoniazid, niacin, phenothiazines (eg, chlorpromazine), progesterones (eg, medroxyprogesterone), somatropin, sympathomimetics (eg, albuterol, epinephrine, terbutaline), or thyroid hormones (eg, levothyroxine) because they may decrease Humulin N vials's effectiveness, resulting in high blood sugar

Important safety information:
- Drowsiness, dizziness, light-headedness, or blurred vision may occur while you use Humulin N vials. These effects may be worse if you take it with alcohol or certain medicines. Use Humulin N vials with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Do not drink alcohol without discussing it with your doctor. Drinking alcohol may increase the risk of developing high or low blood sugar.
- Do NOT take more than the recommended dose, use Humulin N vials more often than prescribed, or change the type or dose of insulin you are using without checking with your doctor.
- 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 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 Humulin N vials before you receive any medical or dental care, emergency care, or surgery.
- If you will be traveling across time zones, consult your doctor concerning adjustments in your insulin schedule.
- 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 non-diet soda. This will raise your blood sugar levels 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.
- Proper diet, regular exercise, and regular testing of blood sugar are important for best results when using Humulin N vials.
- Lab tests, including fasting blood glucose levels and hemoglobin A1c, may be performed while you use Humulin N vials. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use Humulin N vials with caution in the ELDERLY; if low blood sugar occurs, it may be more difficult to recognize in these patients.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Humulin N vials while you are pregnant. It is not known if this medicine is found in breast milk. If you are or will be breast-feeding while you use Humulin N vials, check with your doctor. Discuss any possible risks to your baby.
