How Does Lyumjev Lower Blood Glucose?

Insulin lispro-aabc increases glucose uptake into muscle and fat cells and decreases glucose production by the liver. Its formulation is designed for rapid absorption after subcutaneous injection, allowing use around mealtimes.

Who Is Treated With Lyumjev?

Lyumjev is used in adults and pediatric patients who need rapid-acting insulin for diabetes management. Subcutaneous treatment is usually paired with intermediate-acting or long-acting insulin. Doses are individualized according to glucose readings, meals, activity, and other clinical factors.

How Is Lyumjev Dosed?

Lyumjev U-100 or U-200 is injected subcutaneously at the beginning of a meal or within 20 minutes after the meal begins. The number of insulin units is individualized rather than fixed. Only U-100 is used in compatible insulin pumps or for intravenous administration under medical supervision. U-200 must not be used in pumps or given intravenously.

What Serious Risks Are Linked to Lyumjev?

Severe hypoglycemia is the principal serious risk and can cause seizures, unconsciousness, or death. Other concerns include hypokalemia, severe allergic reactions, insulin administration errors, injection-site reactions, lipodystrophy, and localized cutaneous amyloidosis. Blood glucose is monitored closely when insulin regimens change. U-200 must not be transferred from a pen into a syringe, which can cause a dosing error.
