How to Inject Mounjaro: A Step-by-Step Guide

Starting a new medication, especially one that requires self-injection, can feel a little daunting. At PillSorted, your personal pharmacy in Cambridge, England, we understand this completely. That’s why we’ve created this clear, step-by-step guide on how to inject Mounjaro, using the Mounjaro KwikPen. Mounjaro (tirzepatide) is an important medication used for managing type 2 diabetes and chronic weight management. Our aim is to ensure you feel confident and comfortable with every step of your treatment journey.

Understanding Your Mounjaro KwikPen: What’s in Your Kit?

When you receive your Mounjaro KwikPen from PillSorted, you’ll find a complete package designed to make your treatment as straightforward as possible. Here’s what you can expect:

• Mounjaro KwikPen: This pre-filled pen contains four doses, equivalent to a whole month’s supply of medication. Each pen is calibrated to deliver your prescribed dose accurately.
• Swabs and Needles: We provide sterile alcohol swabs for cleaning your injection site and fresh needles for each dose. Always use a new needle for every injection to ensure sterility and minimise discomfort.
• Sharps Bin: If it’s your first time receiving an injectable medication, you’ll also receive a sharps bin. This is essential for safe disposal of used needles.
• User Manual and Patient Information Leaflet (PIL): These documents contain crucial information about Mounjaro, including detailed instructions for use, potential side effects, and storage guidelines. We strongly advise you to read them thoroughly before your first injection.

Important Storage Guidelines

Proper storage ensures the effectiveness of your Mounjaro KwikPen:

• Unused pens: Keep unused Mounjaro pens in the refrigerator (2°C to 8°C).
• In-use pens: Once you start using a pen, you don’t need to keep it in the fridge. It can be stored at room temperature (up to 30°C) for up to 30 days.
• Protection: Always keep the pen cap on to protect it from light.

Before You Inject: How to Check Your Mounjaro Pen

Before you even think about how to inject Mounjaro, it’s vital to perform a quick check of your Mounjaro KwikPen. This ensures the medication is safe and ready for use.

• Inspect the Liquid: Unscrew the cap and look at the liquid inside the pen. It should be clear and colourless.
• Check for Particles: There should be no visible particles floating in the liquid. If you notice any discolouration or particles, do not use the pen. Please contact PillSorted immediately for advice.
• Air Bubbles: It’s normal to see small air bubbles in the liquid. You can gently tap the pen to encourage them to rise to the top, but they won’t affect your dose or safety.

Step-by-Step Guide: How to Inject Mounjaro Safely

Now, let’s get into the practical steps of how to inject Mounjaro.

Preparing Your Mounjaro Pen and Needle

1. Wash Your Hands: Always start by washing your hands thoroughly with soap and water.
2. Clean the Pen Head: Take an alcohol swab and gently clean the rubber stopper on the head of your Mounjaro KwikPen. Allow it to dry completely.
3. Attach the Needle: Take a new, sterile needle. Peel off the paper tab and carefully screw the needle onto the pen head. Ensure it’s firmly attached but don’t overtighten.
4. Remove the Caps: You’ll notice two caps on the needle. First, remove the outer cap and set it aside (you’ll need this later). Then, carefully remove the inner cap, exposing the needle. Be careful not to touch the needle itself.

Priming Your Mounjaro Pen

Priming the pen is a crucial step for new pens to ensure proper medication flow and remove any air from the needle. While it’s particularly important for the first dose from a new pen, you can also do it before each dose if it makes you feel more confident.

1. Set the Dose to Zero: Turn the dose selector to “0”.
2. Click for the Long Line: Press the injection button until you see a long line appear in the dose window. This indicates the pen is ready for priming.
3. Expel a Drop: Hold the pen with the needle pointing upwards. Press the injection button fully. You should see a small drop of medication appear at the tip of the needle. If you don’t see a drop, repeat the priming process. If still no drop appears after repeating, do not use the pen and contact your pharmacist.

Choosing Your Injection Site

Mounjaro is administered via subcutaneous injection, meaning it goes into the fatty tissue just under your skin. Recommended injection sites include:

• Your Abdomen (Tummy): Avoid the area within 5cm (2 inches) of your navel.
• Your Thighs: Use the front or outer part of your thighs.
• Your Upper Arms: The outer back part of your upper arms.

Rotate your injection sites. It’s extremely important not to inject into the same spot repeatedly. Rotating sites helps prevent skin irritation, bruising, and the development of hardened tissue (lipohypertrophy), which can affect medication absorption.

Performing the Mounjaro Injection

Once your pen is primed and you’ve chosen your site, you’re ready to learn the final steps of how to inject Mounjaro.

1. Dial Your Dose: Turn the dose selector to your prescribed dose (e.g., “1” for 1mg). You’ll hear clicks as you turn, and the number will appear in the dose window.
2. Prepare the Skin: Clean your chosen injection site with a new alcohol swab and let it air dry completely.
3. Inject the Medication:
   • Gently pinch a fold of skin at the injection site.
   • Insert the needle straight into the pinched skin at a 90-degree angle. You don’t need to press it in too hard, just enough to get the needle fully under the skin.
   • Press the injection button firmly and hold it down. You will hear a click as the injection begins.
   • Keep the button pressed down and count slowly to 5-10 seconds to ensure the full dose has been delivered. The dose window should return to “0”.
   • Once the dose window shows “0”, carefully withdraw the needle from your skin.

After Your Injection: How to Discard Your Mounjaro Needle

Proper disposal of your needle is essential for safety. This is a critical part of understanding how to inject Mounjaro responsibly.

1. Recap the Needle: Carefully place the outer cap back onto the needle. Do not try to re-cap the inner needle cap to avoid accidental needle sticks.
2. Untwist and Discard: Twist the capped needle counter-clockwise to remove it from the pen. Immediately place the used needle into your sharps bin. Do not dispose of needles in your regular household waste.
3. Store Your Pen: Replace the cap on your Mounjaro KwikPen and store it safely for your next dose, following the storage guidelines mentioned earlier.
