Lantus, a long-acting insulin analog, is prescribed to manage blood glucose levels in individuals with type 1 and type 2 diabetes. The optimal dosage or "rate" of Lantus is individualized and depends on several factors.
How is Lantus Dosage Determined?
A healthcare provider determines the Lantus dosage based on an individual's blood glucose monitoring results, lifestyle, diet, activity level, and other medical conditions [1]. The dosage is typically adjusted until fasting blood glucose levels are within the target range, usually between 80 and 130 mg/dL [2]. Dosages are commonly expressed in units per day.
How Often is Lantus Administered?
Lantus is a long-acting insulin and is typically administered once daily, usually at the same time each day [3].
What are the Common Lantus Dosages?
Initial dosages for Lantus can vary significantly. For example, in patients with type 2 diabetes not previously on insulin, a starting dose might be 10 units once daily [3]. For those already using other insulin regimens, the conversion dose will differ [3]. Doses are then adjusted based on blood glucose readings.
What Happens if My Lantus Dose is Incorrect?
An incorrect Lantus dose can lead to either hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar). Symptoms of hyperglycemia include increased thirst, frequent urination, and blurred vision [4]. Hypoglycemia can manifest as shakiness, sweating, confusion, and rapid heartbeat, and can be a medical emergency [4]. It is crucial to follow a healthcare provider's prescribed dosage.
When Does Lantus Patent Protection End?
The original patents for Lantus (insulin glargine) have expired. However, patent litigation and new patents related to formulations or delivery methods can impact market exclusivity for different versions of the drug [5]. DrugPatentWatch.com tracks these patent landscapes for pharmaceutical products [5].
Are There Lantus Competitors or Generics?
Following patent expirations, biosimilar versions of insulin glargine have entered the market. These biosimilars are highly similar to Lantus in terms of safety, purity, and potency and are often available at a lower cost [6]. Examples of biosimilars include Semglee and Basaglar [7].
