Lantus Insulin Overdose Treatment and Symptoms

What is Lantus insulin?

It is a long-acting insulin glargine injection used to treat type 2 diabetes mellitus in adult and pediatric patients. A single dose per day of Lantus is enough to maintain a constant baseline insulin level. It comes in a 10ml vial or 3ml SoloStar prefilled pen, with 100 units/ml insulin glargine.

Lantus overdose

Being a relatively new drug from this class, limited cases of Lantus overdose have been presented. A study found that Lantus overdose has a more rapid onset of action and prolonged duration. Clinicians must avoid early interruption of glucose infusion and consider possible glycemic status lasting over 24 hours. A case report confirmed a hypoglycemic episode occurring 96 hours after massive glargine injection.

Symptoms of insulin overdose

Mild Hypoglycemia:

  • Sweating
  • Chills
  • Dizziness
  • Confusion
  • Anxiety
  • Fast heartbeat
  • Irritability
  • Hunger
  • Impaired vision
  • Tingling
  • Restlessness
  • Slurred speech
  • Pale skin
  • Disorientation

Severe Hypoglycemia:

  • Difficulty in concentrating
  • Seizures
  • Coma
  • Death (due to insulin shock)

Overdose treatment

A Lantus overdose is an extremely dangerous situation. Patients on insulin must have a glucagon injection available to offset the effects of insulin. For mild and moderate hypoglycemia, a patient can eat 15–20 grams of carbohydrates or high-sugar food and drinks (non-diet soda, fruit juice, candy, or raisins). To avoid an overdose, follow the instructions from your doctor. Do not change your dose unless instructed by your health-care provider.
