How switching works
1
Complete your assessment
Tell us your current Mounjaro dose, how long you’ve taken it, and any side effects.
2
Prescriber review
Our prescriber confirms whether a switch is appropriate and sets your safe starting dose.
3
Delivery to your door
If approved, your treatment is dispensed by our GPhC-registered pharmacy with tracking.
Already treated elsewhere? If you’re new to Online UK Pharmacy, you’ll need to show evidence of your current treatment — the medicine name, strength, date, and your full name — so the prescriber can verify your dose. Upload it during your assessment; without it, your review may be delayed.

Frequently asked questions
Wegovy is a once-weekly GLP-1 injection with strong long-term safety data and proven results, and it’s often more affordable at maintenance. Some people find the early titration gentler.
Switching to Wegovy (injection or tablet) is a common choice, as it’s frequently cheaper at maintenance. Our prescriber can recommend the right plan during your assessment.
Both support significant weight loss. Mounjaro showed a higher average in head-to-head trials, but Wegovy has extensive long-term safety and cardiovascular evidence.
The common GLP-1 effects — nausea, constipation, fatigue — can occur with all of them. Switching with careful titration usually keeps flare-ups manageable.
It’s the same active ingredient (semaglutide) as a once-daily tablet instead of a weekly injection — no needles, taken on an empty stomach. A 7-day washout applies when switching from an injection.
Yes. Every switch includes a prescriber-set titration plan, dose check-ins, and a direct line to our team.
