Read the Patient Information Leaflet if available from your pharmacist before you start using this medication and each time you get a refill. Ask your health care professional how to prepare and use this medication. If you have any questions, ask your doctor or pharmacist.

Inject this medication under the skin as directed by your doctor, usually once or twice a day. The injection is given in the stomach area, the thigh, the buttocks, or the back of the upper arm. Do not inject into a vein or muscle because very low blood sugar (hypoglycemia) may occur.

The dosage is based on your medical condition and response to treatment. Measure each dose very carefully because even small changes in the amount of insulin may have a large effect on your blood sugar.

Before using, gently roll the vial or cartridge, turning it upside down and right side up 10 times to mix the medication. Do not shake the container. Check this product for particles or discoloration. If either is present, do not use the insulin. Insulin isophane should look evenly cloudy/milky after mixing. Do not use if you see clumps of white material, a "frosty" appearance, or particles stuck to the sides of the vial or cartridge.

Before injecting each dose, clean the skin you are going to inject into (the injection site) with rubbing alcohol. Change the injection site each time to lessen injury under the skin (for example, pits/lumps or thickened skin). Do not inject into skin that is red, swollen, itchy, or damaged. To lessen bruising, do not rub the injection site after a shot. Do not inject cold insulin because this can be painful. The insulin container you are currently using can be kept at room temperature. Learn how to store and discard medical supplies safely.

This product may be mixed only with certain other insulin products such as insulin regular. Always draw the insulin regular into the syringe first, then follow with the longer-acting insulin. Never inject a mixture of different insulins into a vein. Consult your health care professional about which products may be mixed, the proper method for mixing insulin, and the proper way to inject mixtures of insulin. Do not mix insulins if you are using an insulin pump.

Do not change brands or types of insulin without directions on how to do so from your doctor.

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.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time(s) each day.

Tell your doctor if your condition does not improve or if it worsens (your blood sugar is too high or too low).
