Starting Mounjaro is an exciting step toward better health and sustainable weight loss — but doing it the right way is essential. At PPRX, our pharmacists guide you through each stage of your treatment to ensure you start safely and confidently using your first 4-week Mounjaro KwikPen.
This guide explains everything you need to know before taking your first dose, how the pen works, and what to expect during your first month.
Step 1: Begin with the Free Online Consultation
Before starting, complete our secure online consultation form.
It only takes a few minutes and allows our healthcare team to confirm that Mounjaro is safe and appropriate for you. Once approved, you’ll receive your prescription and can order your first pen directly from our pharmacy.
Step 2: Start with the 2.5 mg Mounjaro Dose
All patients begin with the 2.5 mg Mounjaro KwikPen. This starting dose is designed to help your body adjust gradually to the medication while minimising side effects such as nausea or reduced appetite.
Each KwikPen lasts four weeks — one injection per week. After completing the first pen, you can move up to the next strength (5 mg), depending on your progress and how your body responds.
Step 3: How to Use the Mounjaro KwikPen
The KwikPen is a pre-filled, ready-to-use injection pen that makes weekly dosing simple.
How to use it safely:
• Wash your hands and check the pen’s expiry date.
• Attach a new sterile needle for each injection.
• Inject into the stomach, thigh, or upper arm — rotate sites each week.
• Hold the pen firmly against the skin and press the injection button until you hear a click.
• Count slowly to 10 to ensure the full dose is delivered before removing the pen.
Our pharmacists can provide one-to-one advice or written guidance if you’re new to self-injection.
Step 4: What to Expect During the First 4 Weeks
During your first month, you’ll notice changes such as:
• Feeling full faster and eating smaller portions.
• Reduced cravings for sugary or fatty foods.
• Steady, gradual weight loss (often 2–4 kg in the first four weeks).
• Possible mild side effects like nausea or tiredness as your body adjusts.
These effects are normal and usually improve within a few days. Staying hydrated, eating smaller meals, and avoiding greasy foods can help reduce discomfort.
Step 5: Keep Your Mounjaro Pen Stored Correctly
Mounjaro pens must be kept refrigerated (2°C–8°C) until opened. Once in use, you can store the pen at room temperature for up to 30 days. Always protect it from heat and direct sunlight.
All orders from PPRX are shipped in cold-chain packaging to ensure your pen stays within the correct temperature range.
Step 6: Re-Order Before Your 4 Weeks End
Each Mounjaro KwikPen provides four weekly doses. Reorder your next strength before your final dose to avoid any gaps in treatment. You can easily reorder via our Mounjaro product page.
