What is Lantus?
Lantus comes as a sterile solution, known by its generic name insulin glargine, which is administered subcutaneously in patients with type 1 and type 2 diabetes. Insulin glargine refers to a long-acting insulin analog that is available as a prescription insulin drug. This insulin has a constant peak time in lowering blood glucose levels and can last over a time period of 24 hours. Insulin glargine is supposed to have a colorless and clear appearance. In case it has changed colors or is cloudy, you should not use it. Your pharmacist will be able to replace it and give you a new one. Lantus comes in vials or a disposable prefilled pen.
