  • Even on the lowest starter dose you will see some weight loss
  • Mild side effects (mainly nausea) are common but usually settle after a few days
  • Weigh yourself regularly and share your progress with the SemaPen team
  • Access the tools in the SemaPen app and programme benefits

Pen strength increased gradually each month to minimise side effects

Month 2

  • Receive your second pen
  • Nausea might temporarily kick in again as the pen strength has increased
  • Portions stay small and you feel less hungry
  • Make healthy habits a part of your routine; it’s about sustainable change.

Month 3

  • Receive your third weight loss pen
  • Start seeing improvements in your energy levels, sleep and mood*
  • You could have lost up to 10% of your starting weight by the end of this month, especially with Mounjaro*


*Please note that weight loss may vary between individuals.

Month 4

  • Receive your fourth weight loss pen
  • Expect some transient side effects in the first week as you are now on one of the stronger dose pens
  • Targeted support from our experts continues to keep you on track
  • Weigh yourself regularly to stay accountable
  • Unlike with stalled diets, with the Semapen programme you can expect to see continued steady weight loss

Month 5 onwards

  • You will now be on the strongest 2.4mg Wegovy pen (with Mounjaro it takes another month to reach the top dose of 15mg)
  • You will continue losing weight steadily over the next 40 weeks
  • After 1 year on the SemaPen programme we expect
    • More than 9/10 will lose (and keep off) at least 5% of their starting body weight.
    • 75% will have lost more than 10% of their starting weight
    • The average weight loss at this stage is 15% (Wegovy) to 21% (Mounjaro) of starting body weight
  • But you must stick to the programme – there is a good chance you will regain 2/3 of what you’ve lost if you stop!
  • Some people find the highest dose pens too strong – you can use the SemaPen app to control your prescription and step down to a slightly lower dose if you’d prefer


You should continue on the highest dose you can tolerate to avoid weight regain
