Mounjaro KwikPen: How to Use, Doses, Storage and Safety Information, Onlinepharmaustralia. If you have been prescribed Mounjaro (tirzepatide), you may have questions about the Mounjaro KwikPen, including how it works, how often it is used, how many doses are in each pen, how it should be stored and what to do with the pen after use.
The Mounjaro KwikPen is a multi-use injection device designed to deliver a fixed weekly dose of tirzepatide. It is intended for adults who have been prescribed Mounjaro by an appropriate healthcare professional.
This guide explains the key information Australian patients should know about the Mounjaro KwikPen. It does not replace the Consumer Medicine Information (CMI), Instructions for Use (IFU), or advice from your doctor or pharmacist.
What Is the Mounjaro KwikPen?
The Mounjaro KwikPen is a pre-filled, multi-use injection pen containing tirzepatide.
Tirzepatide is the active ingredient in Mounjaro. It acts on GIP and GLP-1 receptors and is used as part of treatment for certain adults with type 2 diabetes and for chronic weight management when prescribed appropriately.
Unlike a single-use injection device, the KwikPen is designed to provide four complete weekly doses.
Each dose is delivered using a new compatible pen needle. Pen needle tips are not included with the Mounjaro KwikPen, so patients should speak with their healthcare professional or pharmacist about suitable needle tips.
How Often Do You Use the Mounjaro KwikPen?
Mounjaro is administered once a week.
It can generally be taken at any time of day and with or without food. Try to use it on the same day each week so that your treatment schedule is easier to remember.
If you need to change your regular injection day, there should be at least 72 hours between Mounjaro doses.
Do not change your dose or injection schedule without discussing it with your prescribing healthcare professional.
How Many Doses Are in a Mounjaro KwikPen?
A Mounjaro KwikPen is designed to provide four complete weekly doses.
The pen contains additional solution required for priming. After the fourth full dose, the pen mechanism prevents another complete dose from being dialled.
You may still see some liquid remaining in the pen after the fourth dose. This does not mean that another complete dose is available.
Do not attempt to extract or use leftover medicine from the KwikPen.
After the fourth dose, the pen should be disposed of appropriately, including any remaining medicine.
What Mounjaro KwikPen Strengths Are Available?
Mounjaro dosing can include:
- 2.5 mg
- 5 mg
- 7.5 mg
- 10 mg
- 12.5 mg
- 15 mg
The appropriate strength depends on your treatment plan and how you respond to the medicine.
The usual starting dose is 2.5 mg once weekly. After four weeks, the dose may be increased to 5 mg once weekly. Further increases may be considered by the prescriber when appropriate.
Your healthcare professional should determine which strength is appropriate for you.
Never increase the dose yourself because you think a higher dose will produce faster results.
How Do You Use the Mounjaro KwikPen?
The KwikPen requires several preparation and injection steps, including attaching a new compatible needle, priming the pen, selecting the prescribed dose and administering the injection correctly.
Because incorrect use can result in an incomplete or incorrect dose, patients should follow the official Mounjaro KwikPen Instructions for Use supplied with their medicine.
Your doctor, pharmacist or other trained healthcare professional can also demonstrate the injection technique.
The manufacturer’s Australian patient guidance provides an instructional video and directs patients to the CMI and Instructions for Use for the complete procedure.
Do not rely on an online article as a replacement for the instructions supplied with your medicine.
Should You Use a New Needle for Every Injection?
Yes.
A new compatible pen needle should be used for each injection.
Do not reuse pen needles and do not share your Mounjaro KwikPen with another person.
Sharing an injection device can expose another person to medication and creates an infection risk.
Used needles should be placed into an appropriate sharps container immediately after use.
How Should You Store Mounjaro KwikPen?
Correct storage is important for maintaining the quality of the medicine.
Mounjaro KwikPen should normally be stored in a refrigerator at 2°C to 8°C and protected from light.
Do not freeze Mounjaro.
Do not use Mounjaro if it has been frozen.
The medicine should also be protected from excessive heat. If refrigeration is unavailable, the Australian manufacturer states that a multi-use KwikPen may be stored below 30°C for a total of up to 30 days, protected from light.
If you are unsure whether your pen has been stored correctly, speak with a pharmacist or healthcare professional before using it.
Can Mounjaro Be Taken Straight From the Refrigerator?
Mounjaro does not need to be warmed to room temperature before injection.
The Australian manufacturer recommends keeping the medicine refrigerated until you are ready to administer the dose.
If you have questions about how long your pen has been outside the refrigerator or exposed to different temperatures, ask your pharmacist before using it.
What If Your Mounjaro KwikPen Is Dropped?
If your KwikPen is dropped onto a hard surface, do not automatically assume that it is safe to use.
Inspect the device and follow the manufacturer’s instructions. If you are uncertain whether the pen has been damaged, speak with your pharmacist or healthcare professional before administering the medicine.
Never use a damaged injection device.
What Happens After the Fourth Dose?
After you have received the fourth complete weekly dose, the KwikPen should be discarded.
Do not attempt to obtain an additional dose from the remaining liquid.
Some medicine may remain inside the device after the fourth dose. This is expected because the pen contains additional solution required for priming and the device is designed to prevent another complete dose from being delivered.
Place the used KwikPen and used needle tips into an appropriate sharps container.
Do not place used needles or the KwikPen directly into household rubbish or recycling.
What If You Forget a Mounjaro Dose?
If you miss a Mounjaro dose, take it as soon as you remember provided there are at least three days, or 72 hours, before your next scheduled dose.
If fewer than three days remain before your next dose, skip the missed dose and take your next dose on your normal day.
Do not take two doses close together to make up for a missed injection.

What Are the Most Common Mounjaro Side Effects?
Mounjaro can cause side effects, particularly gastrointestinal symptoms.
Commonly reported effects can include:
- Nausea
- Diarrhoea
- Vomiting
- Constipation
- Reduced appetite
- Abdominal discomfort
These effects can vary from person to person and may change as treatment progresses.
More serious reactions are also possible. Seek appropriate medical attention if you experience severe or concerning symptoms.

Can You Change Your Mounjaro Dose Yourself?
No.
Your Mounjaro dose should be determined by your prescribing healthcare professional.
Although several KwikPen strengths are available, having access to a higher-strength pen does not mean that you should increase your dose independently.
Dose escalation is generally gradual because tolerability and individual treatment response need to be considered.
If your current dose is causing significant side effects or does not appear to be meeting your treatment goals, discuss this with your doctor rather than changing the dose yourself.

Mounjaro KwikPen and Travel
Travelling with an injectable medicine requires planning.
