Mounjaro
Mounjaro (tirzepatide) is a once-weekly prescription injection that helps adults lose weight by controlling appetite and blood-sugar levels. The Mounjaro KwikPen makes self-injection simple, but using it correctly is essential for safety and effectiveness.
At PPRX Online Pharmacy, our pharmacists review every prescription and provide clear guidance to ensure patients feel confident using their pen at home.
Before You Start Mounjaro
- Store correctly: Keep your Mounjaro pens in the fridge (2°C–8°C).
- Never freeze them.
- If needed, you can keep a pen at room temperature (below 30°C) for up to 21 days.
- Check the pen: Make sure the medicine inside is clear and colourless.
- Wash your hands before each injection.
