Insulin Lispro

What is Insulin Lispro?

Insulin lispro is a rapid-acting insulin taken with meals to control post-meal blood sugar spikes.

How it works

Its structure allows quick absorption after injection, peaking in about 1 hour and lasting 3-5 hours to match meal-related glucose rises.

Common uses

• Mealtime coverage in type 1 diabetes
• Add-on mealtime insulin in type 2 diabetes
• Sliding-scale or correction dosing in clinics and hospitals

Monitoring & Safety

• Labs: Frequent self-monitoring of glucose and periodic hba1c are essential.
• Low blood sugar is the main risk; timing with meals is critical.

Dosing (简要)

• Inject within 15 minutes before eating or right after starting a meal.
• Doses are individualized based on carbs, current glucose, and insulin-to-carb ratios.

Drug interactions

• Other diabetes medicines can increase hypoglycemia risk.
• Corticosteroids or some antipsychotics may raise glucose, requiring dose adjustments.

Patient tips

• Carry quick sugar sources; educate friends/family on treating lows.
• Rotate injection sites and avoid injecting into scar tissue.
• If a meal is skipped, usually skip that mealtime dose to avoid lows.

When to contact your doctor

• Frequent lows or highs despite carb counting.
• Trouble matching doses to meals or exercise changes.
• Redness, swelling, or lumps at injection sites.
