Humalog is indicated for the treatment of diabetes mellitus in adults and children who require insulin for the control of high blood sugar. It is commonly used by individuals with type 1 diabetes and may also be prescribed for people with type 2 diabetes who need insulin therapy to manage their condition.
Humalog is a rapid-acting insulin analog that works by binding to insulin receptors on cells throughout the body, allowing cells to absorb glucose from the bloodstream for energy. It helps lower blood sugar levels more quickly than regular human insulin, typically beginning to work within 15 minutes after injection.
Humalog should be administered as directed by a healthcare provider, usually within 15 minutes before a meal or immediately after eating. Patients should monitor their blood sugar regularly and be aware of signs of low blood sugar (hypoglycemia). It is available in various forms including vials, cartridges, and prefilled pens. Never share injection devices with others.
