Insulin Lantus is used to treat diabetes mellitus in adults, adolescents and children from 2 years of age. In patients with type 2 diabetes, the drug can be used in combination with oral hypoglycaemic agents. Diabetes is a disease caused by insufficient production of insulin necessary to control blood sugar levels. Lantus belongs to long-acting insulins. It can be used as prescribed by your doctor at the same time as short-acting insulin or oral medicines to treat high blood sugar. Can lantus be mixed with regular insulin?
Lantus (insulin glargine) is really unique. It has been designed to create a small pool of slightly acid solution just under the skin that creates micro-CO2 bubbles. Bubbles delay the effect of insulin, so you don’t get a lot of insulin at the same time. The entire Lantus point is a very slow, controlled action.
The use of a chemical reaction with its own subcutaneous fat to slow down the reaction is quite disgusting and kludgey, and newer synthetic analogues use much wiser molecular methods. But if you use Lantus, you must accept this method and not spoil it.
Adding or mixing everything, including another insulin (in the same injection or injection site) will cause a mess. The most likely effect of mixing will be a large rapid unpredictable insulin spike in the first hours instead of the desired slow and controlled action. As you can imagine, this can be dangerous. You can take other insulins but not mixed with Lantus in the same injection or in the same place.
If you use Lantus as your basal insulin and faster insulin, simply inject them at different places. The mixing warning refers to being physically mixed under the skin or in the needle. Injecting two insulins at different places avoids this problem.
Until Lantus and other insulin are mixed together in the syringe or given exactly in the same place on the body, they will not change each other. This means that if you inject these injections at the same time, you should give them in different syringes and at different places on your body.
Insulin Lantus and rapid insulins (Humalog and Novolog) break down faster than regular insulin and NPH.
