Wegovy vs Mounjaro Starter Dose Comparison Guide
Understanding Starter Dose Differences When Switching From Wegovy to Mounjaro
When switching from Wegovy to Mounjaro, the starter dose protocols differ significantly between these prescription-only medicines. Wegovy (semaglutide) begins with 0.25mg weekly for the first four weeks, designed to minimise gastrointestinal side effects whilst allowing your body to adjust gradually. Mounjaro (tirzepatide) starts at 2.5mg weekly, representing a tenfold higher starting dose that reflects its dual-action mechanism. Your prescriber will determine the appropriate washout period between treatments, typically requiring complete elimination of the previous medication before commencing the alternative therapy.
The dose escalation schedules also vary considerably when switching from Wegovy to Mounjaro starter protocols. Wegovy follows a 16-week escalation to reach the 2.4mg maintenance dose, progressing through 0.5mg, 1mg, and 1.7mg stages. Mounjaro escalates more rapidly, increasing by 2.5mg increments every four weeks until reaching the optimal therapeutic dose. Both medications require this gradual escalation for safety reasons, and dose stages cannot be skipped regardless of previous treatment experience. EverydayMeds stocks both starter doses, allowing your prescriber flexibility in treatment selection based on your individual clinical profile.
Pricing Comparison for Switching From Wegovy to Mounjaro Starter Doses
EverydayMeds offers transparent pricing for both medication options when switching from Wegovy to Mounjaro starter doses.

Comparing ongoing costs when switching from Wegovy to Mounjaro requires understanding the complete dose escalation journey. Wegovy's maintenance dose (2.4mg) costs £209.99 monthly, whilst pricing varies for different Mounjaro maintenance doses depending on individual response. Both medications represent significant investments in long-term weight management, requiring commitment to the full escalation protocol alongside reduced-calorie diet and increased physical activity. EverydayMeds offers bundle options to provide convenience and supply security throughout your treatment journey, regardless of which medication your prescriber recommends.
Clinical Evidence Considerations When Switching From Wegovy to Mounjaro
The clinical evidence profiles differ between these medications when switching from Wegovy to Mounjaro starter protocols. Wegovy's STEP trials demonstrated that patients achieved approximately 15% average weight loss at 68 weeks when combined with lifestyle interventions (Wilding et al., NEJM, 2021). The SELECT cardiovascular outcomes trial showed a 20% reduction in major cardiovascular events, supporting Wegovy's dual benefits for weight management and heart health.
Mounjaro's clinical programme involves different trial designs and patient populations, making direct comparison inappropriate when switching from Wegovy to Mounjaro. Both medications work through distinct mechanisms—Wegovy targets GLP-1 receptors exclusively, whilst Mounjaro activates both GIP and GLP-1 receptors as a dual agonist. Your prescriber will evaluate the available evidence alongside your individual medical history to determine the most appropriate option. Both Wegovy and Mounjaro are available from EverydayMeds following clinical assessment, ensuring you receive the treatment best suited to your needs.
How Wegovy Works for Patients Switching From Wegovy to Mounjaro
Understanding Wegovy's mechanism helps inform decisions when switching from Wegovy to Mounjaro starter protocols. Wegovy contains semaglutide, a GLP-1 receptor agonist that mimics natural hormones controlling appetite and satiety. The medication works on brain appetite centres, reducing food cravings and promoting feelings of fullness after smaller meals. This mechanism differs from traditional weight loss approaches, addressing the hormonal regulation of hunger rather than simply restricting calories. The once-weekly injection provides sustained appetite control throughout the week, supporting adherence to reduced-calorie eating patterns. Clinical studies suggest this approach may help patients maintain long-term weight management when combined with appropriate lifestyle modifications.

Storage Differences When Switching From Wegovy to Mounjaro
Storage requirements present practical considerations when switching from Wegovy to Mounjaro starter doses. Wegovy offers superior storage flexibility, remaining stable for six weeks at room temperature below 30°C once removed from refrigeration, compared to Mounjaro's 21-day room temperature limit. Both medications require refrigeration at 2-8°C before first use and utilise pre-filled injection pens for convenient weekly dosing. The FlexTouch pen system for Wegovy provides dose confirmation and safety features, whilst Mounjaro uses KwikPen technology with similar functionality. Consider these practical factors alongside clinical considerations when switching from Wegovy to Mounjaro, particularly if you travel frequently or have limited refrigeration access.
Switching Protocols and Timing When Moving From Wegovy to Mounjaro
Proper switching protocols ensure safety when transitioning from Wegovy to Mounjaro starter doses under prescriber guidance. Semaglutide's half-life requires approximately one week for elimination, meaning most prescribers recommend a washout period before commencing tirzepatide therapy. This prevents overlapping GLP-1 receptor stimulation and reduces the risk of excessive gastrointestinal effects during the transition period. Your prescriber may adjust the timing based on your response to the previous medication and individual clinical factors.
Restarting with appropriate starter doses remains essential when switching from Wegovy to Mounjaro, regardless of your previous dose level. The different receptor profiles and potencies mean previous tolerance doesn't predict response to the new medication. Most patients begin with Mounjaro 2.5mg weekly, following the standard escalation protocol despite prior Wegovy experience. This conservative approach prioritises safety whilst allowing optimal dose titration based on efficacy and tolerability. EverydayMeds supports this transition by stocking all necessary starter doses and providing clinical guidance throughout the switching process.
