Switching medications
Lotus provides clinician-guided switching from Wegovy to Mounjaro that keeps you on track.
Who benefits?
Patients consider switching to Mounjaro for a number of reasons. We’ll check your history, goals, and tolerability, then recommend a safe switch plan that works for you.
Thinking about changing from Wegovy? You’re not the only one. Mounjaro is a weekly injection supported by strong clinical evidence for weight management.
It’s an option worth considering when you want to keep making progress.
The decision depends on your medical background, current dose, side-effects, and weight-loss goals.
Our clinicians confirm suitability, set your starting dose, and support you through titration so you can settle in comfortably.
| Wegovy dose (current) | Mounjaro dose (new) |
| 0.25 mg | 2.5 mg |
| 0.5 mg | 2.5 mg |
| 1 mg | 2.5 mg |
| 1.7 mg | 2.5 mg |
| 12.5 mg | 2.5 mg |
| 2.4 mg | 2.5 mg |
Please note: Don’t overlap weekly injections. Your prescriber will advise a washout gap between your last Wegovy dose and your first Mounjaro dose. You’ll start Mounjaro low and increase gradually to balance results with tolerability.
No overlap. Short washout. Restart low, then step up slowly. Use this table as a quick reference. Your clinician’s advice always comes first.
| Stage | What you do | Weekly dose | Notes |
| Last Wegovy dose | Take your final Wegovy injection, then pause. | N/A | Do not combine with Mounjaro. |
| Washout gap | Wait for a period of time (gap) set by your prescriber. | N/A | No injections during the gap. |
| Weeks 1–4 | Start Mounjaro once weekly. | 2.5 mg | Everyone restarts low after switching. |
| Weeks 5–8 | If needed and tolerated, step up. | 5 mg | Minimum 4 weeks at each step. |
| Weeks 9–12 | Consider next step if needed/tolerated. | 7.5 mg | Pause or step back if side-effects flare. |
| Weeks 13–16 | Consider next step if needed/tolerated. | 10 mg | Stay at the lowest effective dose. |
| Weeks 17–20 | Consider next step if needed/tolerated. | 12.5 mg | Clinician-guided titration. |
| Week 21+ | Only if still needed/tolerated. | 15 mg (max) | Maintenance at the dose that suits you. |

Supporting your transition
Use our live chat, contact form or email us at support@lotusweightloss.co.uk and we’ll support you every step of the way.
Clinical trials show meaningful weight loss with appropriate dosing and lifestyle support. Individual results vary, but many patients do well when they switch and step-up gradually.
If you’ve plateaued on Wegovy, had supply issues, or want to explore a different mechanism, a supervised switch to Mounjaro can be a sensible next step.
Mild GI symptoms may return when you start low and step up. That’s common and usually settles. We’ll support you with timing, food choices, and dosing cadence.
Common questions
No. Don’t overlap. Finish your Wegovy treatment and pause for the prescriber-advised gap. Only then start Mounjaro at 2.5 mg.
Often around a week, but it is usually personalised, and depends on your last Wegovy dose, side-effects, and your medical history. We’ll confirm your exact gap during review.
These are very different medicines and different dosing. Switching from Wegovy to Mounjaro restarts your body at 2.5 mg once weekly for 4 weeks, then steps up in 2.5 mg increments at around 4-week intervals.
Some people worry about this. Most do fine with a simple plan: hit your protein target, prioritise fibre and veg, keep steps up, watch evening snacking, and keep alcohol to a minimum.
Mild nausea, reflux, constipation or diarrhoea can reappear when you switch, but is usually short-lived. Eat smaller meals, slow down at the table, and avoid rich or fatty foods on dose day. Tell us if symptoms are moderate or persistent.
If you miss a Mounjaro dose, take it within 4 days (96 hours) of the missed day, then resume your usual weekly schedule. If it’s been more than 4 days, skip it and take the next dose on your normal day. Don’t double up.
If you miss a Wegovy dose and it’s within 5 days, take it and carry on. If over 5 days, skip it and take your next dose on the usual day. Your prescriber will confirm if your washout timing needs a minor adjustment.
Yes. This is often possible with a short one-off adjustment. As us and we’ll advise the safest way to move your dose day and keep a weekly schedule.
Possibly. If you use insulin or a sulfonylurea, there’s a higher risk of low blood sugar when starting or stepping up. Contact us if you have any concerns.
Tell us. We can keep you on a lower dose for longer, step back, or try symptom strategies such as(meal size, timing, ginger / peppermint, hydration and avoiding high-fat meals on dose day.
