Lantus Side Effects

Clinical studies have shown that some people may experience low blood sugar or reactions at the injection site while using Lantus. Side effects of this medication tend to be minor and are generally easy to treat. However, some side effects should be reported to your healthcare provider right away, including seizures, difficulty breathing, and difficulty speaking.

An Introduction to Lantus Side Effects

As with any medicine, side effects are possible with Lantus® (insulin glargine). However, not everyone who takes the drug will experience side effects. In fact, many people tolerate it quite well. If side effects do occur, they are often minor and either require no treatment or are easily treated by you or your healthcare provider.
 
(This article covers many, but not all, of the possible side effects with Lantus. Your healthcare provider can discuss a more complete list with you.)
 

Possible Side Effects of Lantus

Lantus has been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were documented and compared to the side effects that occurred in another group of people taking a different form of insulin, usually NPH insulin.
 
While studies for most medications compare the medication to a placebo (a "sugar pill" that does not contain any active ingredients), this is not usually possible for diabetes medications like Lantus. It would be unethical to give a placebo to people with diabetes, as it is essential to keep blood sugar under control. This is why Lantus was compared to other insulins rather than to a placebo.
 
In these studies, possible Lantus side effects included:
 
  • Low blood sugar levels (hypoglycemia)
  • A skin reaction at the injection site
  • Skin thickening or pitting at the injection site.
