Read the patient information leaflet provided by your pharmacist before you start using this medication and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Follow all package directions for proper use/injection/storage of the particular type of device/insulin you are using. Your health care professional will teach you how to properly inject this medication. If any of the information is unclear, consult your doctor or pharmacist. Do not inject cold insulin because this can be painful. The insulin container you are currently using can be kept at room temperature (see also Storage section). Wash your hands before measuring and injecting insulin. Check the product visually for particles, thickening, or clumps before rolling and turning the container. If any are present, discard that container. To avoid damaging the insulin, do not shake the container. Gently roll and turn it between your palms at least 10 times. If using a cartridge or prefilled syringe, turn it upside down so that the glass ball moves from one end to the other. Gently mix the insulin until it appears evenly white and cloudy. If it does not appear this way, discard it. The dosage is based on your medical condition and response to treatment. Measure each dose carefully, and use exactly as prescribed by your doctor. Even small changes in the amount of insulin may have a large effect on your blood sugar. Before injecting each dose, make sure the injection site is clean and dry. Inject this medication under the skin of the abdomen, upper arms, or thighs, usually twice daily, 15 minutes or less before the morning and evening meal or as directed by your doctor. Do not inject into a vein or muscle. Eat promptly after taking this insulin to avoid low blood sugar (see also Side Effects section). Change where you inject each time to lessen the risk of problems or damage under the skin (for example, pits/lumps or thickened skin). Do not inject into skin that is red, swollen, itchy, or damaged. Do not mix this product with other insulins or use it in an insulin pump. Use this medication regularly as directed by your doctor in order to get the most benefit from it. Carefully follow the insulin treatment plan, meal plan, and exercise program your doctor has recommended. Monitor your blood sugar on a regular basis. Keep track of the results, and share them with your doctor. This is very important in order to determine the correct insulin dose. If you are measuring doses from vials, do not reuse needles and syringes. If you are using the cartridges or pens, use a new needle each time. Do not share your pen device with another person, even if the needle is changed. You may give other people a serious infection, or get a serious infection from them. Learn how to store and discard medical supplies safely. Tell your doctor if your condition does not improve or if it worsens (your blood sugar is too high or too low).

See also the How to Use section. Pain, redness, swelling or itching at the injection site may occur. These effects usually go away after a few days or weeks. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Too much insulin can cause low blood sugar (hypoglycemia). This effect may also occur if you do not consume enough calories. The symptoms include chills, cold sweats, blurred vision, dizziness, drowsiness, shaking, fast heartbeat, weakness, headache, fainting, tingling of the hands/feet, or hunger. It is a good habit to carry glucose (sugar) tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, raise your blood sugar quickly by eating a quick source of sugar such as table sugar, honey, candy, or drinking a glass of fruit juice or non-diet soda. Tell your doctor right away about the reaction. To help prevent low blood sugar, eat meals on a regular schedule and do not skip meals. Too little insulin can cause high blood sugar (hyperglycemia). Symptoms of high blood sugar include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, or fruity breath odor. If these symptoms occur, tell your doctor right away. Your treatment plan may need to be changed. This medication may cause low potassium levels in the blood (hypokalemia). Tell your doctor right away if any of these unlikely but serious side effects occur: muscle cramps, weakness, irregular heartbeat. A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following signs of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing. This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist. In the US - Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch. In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.

Many drugs can affect your blood sugar, making it harder to control. Before you start, stop, or change any medication, talk with your doctor or pharmacist about how the medication may affect your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high or low blood sugar. (See also Side Effects section.) Your doctor may need to adjust your diabetes medication, exercise program, or diet. Beta-blocker medications (such as metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar falls too low (hypoglycemia). Other symptoms of low blood sugar such as dizziness, hunger, or sweating are unaffected by these drugs. Check the labels on all your medicines (such as cough-and-cold products) carefully. Some products may contain sugar or alcohol and may affect your blood sugar. Ask your doctor or pharmacist about using these products safely. Other medications can affect the results of urine tests for sugar or ketones. Consult your doctor or pharmacist for more information.
