Levemir flexpenvs Lantus

Both Levemir and Lantus are long-acting injectable insulins which can be used for long term management of diabetes. The hormone insulin which is naturally produced in the body by the pancreas helps in the conversion of glucose in the blood stream into the body’s usable energy. This energy once achieved is distributed to cells around the body.

With diabetes, you experience pancreatic failure, a situation in whichthe body produces little to no insulin or it can’t use the insulin in the right way. Without insulin, your body is starved of energy since it can’t use the sugar.  When excess sugar is allowed, it damages other body organs including kidneys and blood vessels. Lantus is a solution of insulin glargine while Levemir is a solution of insulin detemir. Both are basal insulin. This means that they work slowly to lower your blood level sugar. Over a 24-hour period they are absorbed into your body. They help keep your blood sugar level lower for a longer period than short-acting insulin does. Though their formulations are slightly different, Lantus and Levemir are very similar drugs. They have just slight differences.


Both children and adults use Lantus and Levemir. More precisely, Lantus can be used by those who are 6 years old and above whereas Levemir can only be used by people aged from 2 years and above. Both Lantus and Levemir can greatly help with daily management of diabetes. However, you might need to use short-acting insulin to treat diabetic ketoacidosis and spikes in your blood sugar levels. They represent dangerous build ups of acids in your blood.


Both Lantus and Levemir are given through injection on the skin. You can have someone you know give you this injection or simply administer it yourself. Always make sure the injection goes under your skin. It is of great importance to rotate the injection sides around your upper legs, abdomen and upper arms. This will help prevent a build-up of fatty tissues at the injected area. Never use either drug with an insulin pump. Doing so can lead to severe low blood sugar level causing a life threatening situation.



Depending on how quickly your body uses up the drug, you can take levemir once or twice a day. When you are first taking it, make sure you monitor your blood sugar level.Always report the number of times you take the drug to your doctor, in cases there is need for adjustment.


Lantus is generally taken once a day. According to your blood sugar level control, your doctor will choose the number of units you need to use.


In the daily management of blood sugar levels in people with diabetes, both Levemir and Lantus appear to be equally effective. A study conducted in 2011 found no significance difference in the effectiveness or safety of Lantus versus Levemir for type 2 diabetes.
