Why Patients Worry About Side Effects of Wegovy

Mounjaro (tirzepatide) and Wegovy (semaglutide, also known as Ozempic) are both effective weight-loss injections, but patients switching from Mounjaro often worry about side effects when starting Wegovy.

What Happens When You Switch to Wegovy

  • Wegovy works differently: It only targets GLP-1, while Mounjaro targets both GLP-1 and GIP.
  • Dose reset: Even if you were on a high dose of Mounjaro, you must start Wegovy at 0.25mg weekly (unless you’ve taken Wegovy before).
  • Adjustment period: Your body may need time to adapt, and mild side effects like nausea or stomach upset can occur.

Common Wegovy Side Effects

  • Nausea
  • Diarrhoea or constipation
  • Indigestion or bloating
  • Fatigue in the early weeks

These usually improve after a few weeks as your body adjusts.

How to Minimise Side Effects

  • Start with the lowest dose (0.25mg)
  • Increase gradually as advised
  • Eat smaller meals and avoid heavy, fatty foods
  • Stay hydrated and take injections on the same day each week

Cost Savings When Switching

Mounjaro Discounted Prices (September 2025): £235–£500/month
Wegovy Prices: £170–£300/month

Switching to Wegovy can save patients up to £200/month while still delivering strong results.
