Ultrashort insulin analogues (Insulin aspart, insulin lispro, insulin glulisine) — Uses, Dosage, Side Effects & Safety

Drug class: Rapid-acting insulin analogue (antidiabetic agent)

Overview

Ultrashort insulin analogues are a type of rapid-acting insulin used to control high blood sugar in people with diabetes mellitus, including both type 1 and type 2 diabetes. They are designed to act quickly, mimicking the body's natural insulin response to meals. These insulins start working within 10–20 minutes after injection, peak in about 1–3 hours, and last for 3–5 hours. This makes them ideal for use just before or immediately after eating to help manage blood sugar spikes. Key points for patients: Always use ultrashort insulin analogues as directed by your healthcare provider. Monitor your blood sugar regularly, and be aware of signs of low blood sugar (hypoglycemia). Never share insulin pens or syringes.
