What Mounjaro Is and How It Works
Mounjaro works on two natural hormone pathways (GIP and GLP-1). This action helps your body:
Release insulin when needed
Slow down how quickly food leaves your stomach
Reduce appetite
Improve metabolic control
It is used once weekly for diabetes management or weight reduction under clinical supervision.
Getting the Right Dose Before Use Mounjaro
Start Dose: Most patients begin with 2.5 mg once weekly, or as prescribed.
Dose Increases: Dose adjustments are gradual, usually every 4 weeks, based on your progress and tolerance.
Missed Dose: Do not take an extra dose. Simply take your next dose on your scheduled day unless advised otherwise.
Preparing the Mounjaro Pen
Remove the pen from the box and check the expiration date.
Inspect the liquid. It should be clear and colorless.
Wash your hands thoroughly.
Do not shake the pen.
Allow the pen to reach room temperature to make the injection more comfortable.
