Lyumjev Kwikpen ( 3ml Each )

Lyumjev KwikPen (3 mL each) — what it is and why it’s used

Lyumjev KwikPen is a prefilled, disposable insulin pen designed for fast mealtime coverage. It contains insulin lispro‑aabc, an ultra‑rapid–acting insulin that works quickly to help manage blood sugar spikes when you eat. It’s used in adults and children with diabetes who need rapid‑acting insulin around meals. The KwikPen part just means it’s ready to use dial the dose, inject, and move on with your day.

Strengths and pack details you should know

U‑100 and U‑200 options (check your label)

• U‑100: 100 units/mL. Each 3 mL pen has 300 units total.
• U‑200: 200 units/mL. Each 3 mL pen has 600 units total.
  Important: Do not switch between U‑100 and U‑200 without your prescriber’s guidance. The pens look similar but deliver different concentrations. Never transfer insulin from a pen to a syringe especially U‑200 because you could get the wrong dose.

• Pen needles are usually not included. Use compatible single‑use pen needles (ask your pharmacist for size recommendations).

Why Lyumjev? The fast stuff that matters

Ultra‑rapid at mealtime

Lyumjev is formulated to absorb faster than standard rapid insulins, so you can dose at the start of a meal or even within 20 minutes of starting to eat (follow your plan). That flexibility helps when life isn’t perfectly timed.

Pen made for everyday use

• Smooth dialing with clear dose window
• Discreet, portable, and prefilled no vials, no mixing
• Consistent dosing to support accurate carb counting and corrections

Who it’s for (and who it isn’t)

Indicated use

• Adults and pediatric patients who need rapid‑acting insulin for mealtime control
• Used alongside a basal insulin (long‑acting) in multiple‑daily‑injection plans or as directed by your clinician

Not for these situations

• Not to treat diabetic ketoacidosis (DKA)
• The KwikPen itself is for subcutaneous injections only (U‑100 Lyumjev may be used in pumps when supplied appropriately, but the pen is not a pump reservoir)

How to use Lyumjev KwikPen (simple, step‑by‑step)

Before you inject

• Wash your hands. Check the pen label (Lyumjev, U‑100 or U‑200, and that the insulin is clear and colorless).
• Attach a new, single‑use needle each time.
• Prime the pen (often 2 units) until you see insulin at the needle tip. This helps deliver an accurate dose.

When to inject and where

• Timing: Usually at the start of a meal or within 20 minutes of starting your meal, as directed by your prescriber.
• Sites: Abdomen, thigh, or upper arm. Rotate injection sites to prevent lumps or thickened skin.

Dosing basics (follow your plan)

• Your dose is individualized (carb counting, correction factors, and activity matter).
• Don’t change doses on your own unless your care team gave you a titration plan.
• After injecting, count slowly as directed in the leaflet before removing the needle to make sure the full dose is delivered.

Important safety habits

• Never share your pen (even with a new needle).
• Do not mix Lyumjev with other insulins in the pen.
• Remove the needle after each injection and recap the pen.
