Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start using this medication and each time you get a refill. If you have any questions, ask your doctor, diabetes educator, 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. Before using, check the product visually for particles, thickening, or clumps. If any are present, discard that container. Insulin glargine should be clear and colorless. To avoid damaging the insulin, do not shake the container.
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. If you are using the cartridge form of this insulin and a special injecting device with a digital display, take care to read the display right-side up. If you read the display upside-down, you may inject the wrong amount of insulin. Ask your pharmacist if you are unsure how to properly use this type of injecting device.
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 once daily or as directed by your doctor. Do not rub the injection site. Do not inject into a vein or muscle. 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.
Use this medication regularly as directed by your doctor in order to get the most benefit from it. You may inject insulin glargine once daily at any time during the day (such as before breakfast or at bedtime) but you should inject at the same time each day. Carefully follow the insulin treatment plan, meal plan, and exercise program your doctor has recommended.
Do not mix this product with other insulins or solutions, or use it in an insulin pump.
Do not change brands or types of insulin without directions on how to do so from your doctor.
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).
