MOUNJARO KWIKPEN
Key Information
- Active Ingredient: Tirzepatide.
- Mechanism: It mimics natural gut hormones (GIP and GLP-1 receptor agonists) that regulate appetite and enhance insulin secretion, leading to reduced hunger and improved blood sugar control.
- Usage: A once-weekly subcutaneous injection in the abdomen, thigh, or upper arm. Each KwikPen contains four doses (a month's supply), after which it should be discarded even if leftover medicine is visible.
- Dosage: Treatment begins with a starting dose of 2.5 mg once weekly for four weeks. The dose can then be increased by a healthcare provider in 2.5 mg increments every four weeks, up to a maximum dose of 15 mg once weekly, to achieve the desired effect.
- Availability: It is a prescription-only medication and is available in various dosages including 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. It is available for purchase from licensed pharmacies and online clinics following a medical consultation.
- Manufacturer: Eli Lilly and Company.
- Side Effects: The most common side effects are gastrointestinal, including nausea, diarrhea, vomiting, and constipation.
It is important to discuss all potential side effects and concerns with a doctor or pharmacist, as it is a powerful medication.
Potential Side Effects
Most side effects are gastrointestinal in nature and tend to decrease over time.
- Very Common: Nausea, diarrhea, vomiting, and constipation.
- Common: Fatigue, dizziness, bloating, belching, flatulence, heartburn, decreased appetite, injection site reactions, hair loss, and gallstones.
- Serious (rare): Pancreatitis (sudden severe pain in the stomach and back) and severe allergic reactions (anaphylaxis) can occur, requiring immediate medical attention.
Administration
Mounjaro is typically administered once weekly via subcutaneous injection. The dose is usually increased over several weeks, depending on individual response and tolerance, to help minimize potential side effects. The healthcare provider will determine the appropriate starting dose and how it should be adjusted over time.
How to Use the KwikPen
- Preparation: Always wash your hands thoroughly before handling the pen. Inspect the pen to ensure the medication is clear and free of particles.
- Attach Needle: After wiping the inner seal with an alcohol swab, carefully screw on a new pen needle. Needles are generally sold separately.
- Prime the Pen: For a new KwikPen, it is necessary to prime it to remove any air bubbles. This is typically done by turning the dose knob to a specific icon, then pressing it to expel a small amount of liquid.
- Set Dose: Turn the dose knob to the prescribed dose indicated in the pen's window.
- Inject: Insert the needle into the skin at a 90-degree angle in the recommended injection sites (thigh, abdomen, or upper arm). Press and hold the injection button until the dose indicator reaches zero, then wait a few seconds before removing the needle.
- Safety: Immediately after injection, remove the needle and dispose of it in a designated sharps container.
Usage & Dosage
- Schedule: Administered once weekly on the same day each week.
- Initial Dose: Usually starts at 2.5 mg weekly for the first four weeks.
- Maintenance: Doses may increase in 2.5 mg increments every four weeks up to a maximum of 15 mg weekly.
- Injection Sites: Subcutaneous injection into the abdomen, thigh, or upper arm. It is important to rotate the site with each dose.
Side Effects & Storage
- Common Side Effects: Nausea, diarrhea, vomiting, and constipation. These are often most common when starting or increasing the dose.
- Storage: Store unused pens in the refrigerator (2°C–8°C). After first use, the pen can be kept at room temperature (up to 30°C) for up to 30 days. Do not freeze.

“Very easy to use, comes with step-by-step instructions. I found it works almost straight away, with only slight nausea on the first day. Like you only have to inject once a week.”
“Only just had the second shot. It does take away the cravings. Don’t feel that hungry. First few days after the shot, I have felt nausea & slight headache, but it does wear off.”
"My diabetes has been more under control than it’s ever been. Also, the diabetes caused my weight to balloon to 215 lbs and I’m only 5’. I have since lost 65 lbs within 4 months and I feel great! I also changed my lifestyle and eat better and drink lots of water"
