Key takeaways: switching from injections to the Wegovy pill
- Different medicines need careful mapping: Mounjaro (tirzepatide) and Wegovy (semaglutide) are not interchangeable on a 1-to-1 basis. Your starting Wegovy pill dose depends on your current injection strength and tolerability.
- Washout gaps matter: You must wait after your last injection before starting the pill—usually 7 days for mild or no side effects, and 14 days after severe side effects on Mounjaro.
- Wegovy injection to pill is simpler: Both use semaglutide, so your daily tablet dose is matched to be clinically equivalent to your weekly injection after a 7-day gap.
- Clinical review is required: PrivateDoc prescribers confirm your mapped dose during your next required clinical review before authorising any switch.
- Support throughout: Our UK-registered clinical team is available if you experience adjustment symptoms or have questions about your new daily routine.
Switching from Mounjaro to the Wegovy pill
Because Mounjaro (tirzepatide) and Wegovy (semaglutide) use different active ingredients, you cannot simply swap one for the other on a 1-to-1 basis. Your new starting dose of the Wegovy pill depends on your current Mounjaro strength and how your body has tolerated the medication so far.
The standard transition (for none or mild side effects)
If you are experiencing no side effects or very mild side effects on your current Mounjaro dose, you will wait 7 days after your last injection before taking your first Wegovy pill. Your dose will be mapped as follows:
| Current Mounjaro dose |
Starting Wegovy pill dose |
Required gap |
| 2.5mg | 1.5mg | 7 days |
| 5mg | 4mg | 7 days |
| 7.5mg | 4mg | 7 days |
| 10mg | 9mg | 7 days |
| 12.5mg | 9mg | 7 days |
| 15mg | 25mg | 7 days |
If you experience moderate side effects
If you have moderate side effects on Mounjaro, your transition will still require a 7-day gap. However, our clinical team will step your Wegovy pill dose down to a lower introductory strength to give your body time to adjust comfortably.
If you experience severe side effects
Your safety is always our priority. If you experience severe side effects on any dose of Mounjaro, you must take a 14-day gap to allow the medication to fully clear your system. You will then restart your treatment on the lowest introductory dose of the Wegovy pill, which is 1.5mg.
Switching from Wegovy injections to the Wegovy pill
If you are already taking Wegovy injections, transitioning to the pill format is a more straightforward process because both medications share the exact same active ingredient (semaglutide).
Your new daily tablet dose will be matched to be clinically equivalent to your current weekly injection. You will simply wait 7 days after your last injection before taking your first daily tablet. As always, our prescribers will review your specific case to confirm the exact dosage strength before your transition is finalised.
The standard transition (for none or mild side effects)
If you are experiencing no side effects or very mild side effects on your current Wegovy dose, you will wait 7 days after your last injection before taking your first Wegovy pill. Your dose will be mapped as follows:
| Current Wegovy injection dose |
Required gap |
Starting Wegovy pill dose |
| 0.25mg | 7 days | 1.5mg |
| 0.5mg | 7 days | 4mg |
| 1.0mg | 7 days | 4mg or 9mg |
| 1.7mg | 7 days | 9mg |
| 2.4mg | 7 days | 25mg |
| 7.2mg | 7 days | 25mg |
What to expect after the switch
Because your body is adjusting to a new delivery method or a new active ingredient, you may experience a brief period of adjustment.
We pride ourselves on offering real-time human support to our patients. If you experience any new side effects or have questions about your new daily routine, our clinical team is readily available to guide you. Remember that the Wegovy pill works exactly the same way as the injections and must be used alongside a calorie-controlled diet and regular exercise to achieve the best results. For more detail on daily dosing rules, see our guide to long-term success on the Wegovy pill.
