How Do Mounjaro Injection Doses Compare with the Wegovy Pill?
Mounjaro injections and the Wegovy pill contain different active ingredients, so there is no direct dose equivalent between the two treatments.

How Can You Safely Switch from Mounjaro to Wegovy Pill?
Changing from Mounjaro to Wegovy pill should always be done under the guidance of a UK-registered prescriber. As these medicines contain different active ingredients and follow different dosing schedules, a personalised treatment plan helps support a safe and effective transition.
The 7-Day Gap:
A 7-day gap is generally recommended between your final Mounjaro injection and your first Wegovy dose. During this washout period, do not take both medicines at the same time, as this may increase the likelihood of side effects. For example, if your last Mounjaro injection was on a Wednesday, you would usually begin Wegovy the following Wednesday, unless your prescriber advises otherwise.
Dosage Adjustment:
A Mounjaro to Wegovy conversion is not based on a like-for-like dose because the medicines work differently. Your prescriber will consider your previous Mounjaro dose, treatment response, and overall health before recommending the most suitable Wegovy starting dose and dose escalation plan.
Medical Supervision:
Mounjaro and Wegovy are prescription-only medicines that are not directly interchangeable. Regular clinical reviews allow your prescriber to monitor your progress, manage side effects such as nausea or vomiting, and adjust treatment when needed to support safe long-term weight management.
Arrange an online consultation to discuss your current treatment and whether switching medicines is clinically appropriate. A qualified UK prescriber can provide personalised guidance based on your individual health needs.
