Insulin regular is used for:

Treating diabetes mellitus.

Insulin regular is 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 insulin regular if:

  • you are allergic to any ingredient in insulin regular
  • you have a chronic lung disease (eg, asthma, COPD)
  • you are having an episode of low blood sugar or you have an acidic blood problem caused by diabetes (diabetic ketoacidosis)
  • you smoke or you have recently stopped smoking

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

Some MEDICINES MAY INTERACT with insulin regular. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Beta-blockers (eg, propranolol), clonidine, guanethidine, lithium, or reserpine because they may increase the risk of high or low blood sugar or may hide the signs and symptoms of low blood sugar, if it occurs
  • Angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril), angiotensin receptor blockers (eg, losartan), disopyramide, fibrates (eg, clofibrate, gemfibrozil), fluoxetine, monoamine oxidase inhibitors (MAOIs) (eg, phenelzine), other medicines for diabetes (eg, glipizide, metformin, nateglinide), pentamidine, pentoxifylline, pramlintide, propoxyphene, salicylates (eg, aspirin), somatostatin analogs (eg, octreotide), or sulfonamide antibiotics (eg, sulfamethoxazole) because the risk of low blood sugar may be increased
  • Thiazolidinediones (eg, pioglitazone, rosiglitazone) because the risk of heart failure may be increased
  • Atypical antipsychotics (eg, clozapine, olanzapine), corticosteroids (eg, prednisone), danazol, diuretics (eg, furosemide, hydrochlorothiazide), estrogen, glucagon, hormonal contraceptives (eg, birth control pills), isoniazid, niacin, phenothiazines (eg, chlorpromazine), progesterones (eg, medroxyprogesterone), protease inhibitors (eg, boceprevir, ritonavir), somatropin, sympathomimetics (eg, albuterol, epinephrine, terbutaline), or thyroid hormones (eg, levothyroxine) because they may decrease insulin regular's effectiveness, resulting in high blood sugar

This may not be a complete list of all interactions that may occur. Ask your health care provider if insulin regular may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use insulin regular:

Use insulin regular as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Insulin regular comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get insulin regular refilled.
  • Insulin regular is for breathing in only by an inhaler into the lungs.
  • Use insulin regular at the start of a meal, as directed by your doctor.
  • Follow how to use as you have been told by your doctor or follow the instructions in the Medication Guide.
  • It is very important to follow your insulin regimen exactly. Do NOT miss any doses. Ask your doctor for specific instructions to follow in case you ever miss a dose of insulin.

Ask your health care provider any questions you may have about how to use insulin regular.

Important safety information:

  • Drowsiness, dizziness, light-headedness, or blurred vision may occur while you use insulin regular. These effects may be worse if you use it with alcohol or certain medicines. Use insulin regular with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
  • Do not drink alcohol or use medicines that contain alcohol without discussing it with your doctor. Drinking alcohol may increase the risk of developing high or low blood sugar.
  • Do NOT use more than the recommended dose, use insulin regular 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 insulin regular before you receive any medical or dental care, emergency care, or surgery.
  • Low blood potassium may happen with insulin regular. If not treated, this can lead to an irregular heartbeat, very bad breathing problems, and sometimes death. Discuss any questions or concerns with your doctor.
  • Carry an ID card at all times that says you have diabetes.
  • Low blood sugar levels (hypoglycemia) may happen with insulins. This is most likely to occur if you take too much insulin, skip a meal, or exercise too much. Severe low blood sugar levels can cause seizures or death. 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 hungrier. 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 you doctor right away.
  • Proper diet, regular exercise, and regular testing of blood sugar are important for best results when using insulin regular.
  • Lung function has gotten worse in some people taking insulin regular. Have your lung function checked while taking insulin regular. Call your doctor right away if you have new or worsening breathing problems after starting insulin regular.
  • Lab tests may be performed while you use insulin regular. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Use insulin regular with caution in the ELDERLY; they may be more sensitive to its effects, especially low blood sugar. If low blood sugar occurs, it may be more difficult to recognize in elderly patients.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using insulin regular while you are pregnant. It is not known if insulin regular is found in breast milk. If you are or will be breast-feeding while you use insulin regular, check with your doctor. Discuss any possible risks to your baby.
