If you've been prescribed Mounjaro or Wegovy, you may feel unsure about giving yourself an injection for the first time. That's completely normal.
The good news: both medications come in pre-filled, single-use injection pens designed for simple, at-home use. This guide walks you through everything.
This guide covers:
Always follow your clinician's instructions and the official patient leaflet provided with your medication.
💉
Subcutaneous
Into fatty tissue, not muscle
📅
Once Weekly
Same day each week is ideal
🏠
At-Home Use
Pre-filled pen, no vein needed
Abdomen
At least 5cm away from the belly button. Most people find this the easiest and least uncomfortable area.
Front of Thigh
A good alternative if the abdomen isn't comfortable.
Upper Outer Arm
Only if someone else is administering the injection.
💡 Best practice: Rotate injection sites weekly. Avoid bruised, irritated, or scarred skin. Never inject into the exact same spot repeatedly.
Wash Your Hands
Use soap and water or hand sanitiser before handling the pen.
Check the Pen
Prep the Pen
Prime the Pen (Mounjaro only)
Hold the pen with the needle pointing up and tap the cartridge holder gently to collect air bubbles at the top. Push the dose knob in until it stops, then slowly count to 5. The 0 icon must show in the dose window before proceeding.
Inject
Remove and Dispose
Wegovy Storage
Keep for up to 6 weeks below 30°C or in the fridge (2–8°C), away from the cooling element.
Mounjaro Storage
Store at room temperature up to 30°C after injection. Dispose after 4 weekly doses.
Most patients describe a mild sting or quick pinch with minimal discomfort. Here's how to make it even easier:
Let medication reach room temperature before injecting
Relax the muscle before injecting
Avoid injecting immediately after exercise
Rotate sites every week
What if I see a drop of liquid?
A tiny drop at the injection site is normal and does not mean the dose was lost. If medication sprays or leaks significantly, contact your prescriber.
Injecting into muscle rather than fatty tissue
Removing the pen too quickly after injecting
Not holding the pen in place for the full 10 seconds
Reusing a single-use pen
Skipping site rotation
Yes, but aim for the same day weekly. If you miss a dose, follow the official guidance in your patient leaflet.
Can I inject after eating?Yes. These injections are not meal-timed.
Where is the least painful place to inject?Most people find the abdomen easiest.
Can I travel with my injection pen?Yes. Keep refrigerated where possible and check storage instructions for your specific medication. Never freeze.
These medications are prescription treatments for obesity and metabolic disease. Always:
Most people feel confident after just 1 or 2 doses.
The injection itself is quick. The real work is what happens alongside it: nutritional support, muscle preservation, and lifestyle change. You don't have to figure that out alone.
