Wegovy to Mounjaro Dose Equivalent: Complete UK Conversion Guide

Understanding the Wegovy to Mounjaro dose equivalent is essential when switching between these two GLP-1 receptor agonists, as they contain different active ingredients with distinct potency profiles. Wegovy contains semaglutide, whilst Mounjaro contains tirzepatide, a dual GIP/GLP-1 receptor agonist that requires careful dose matching to maintain therapeutic efficacy and minimise side effects during transition[1]. At Cured Pharmacy, our UK-registered clinical team provides personalised guidance on dose conversion alongside transparent pricing from £124.99 for Mounjaro, ensuring safe and effective treatment continuity.

Understanding the Wegovy to Mounjaro Dose Equivalent: Clinical Rationale

The Wegovy to Mounjaro dose equivalent is not a direct milligram-for-milligram conversion, as tirzepatide (Mounjaro's active ingredient) and semaglutide (Wegovy's active ingredient) have fundamentally different receptor mechanisms and potency profiles[1]. Mounjaro activates both GIP and GLP-1 receptors, whilst Wegovy targets only GLP-1 receptors, meaning the therapeutic effect cannot be simply matched by dose alone.

Clinical evidence from the SURPASS-2 head-to-head trial demonstrated that Mounjaro 15mg produced superior weight loss compared to Wegovy 1mg, with an average additional 5.5kg reduction over 40 weeks[2]. This suggests that even Mounjaro's maintenance doses may offer enhanced efficacy, but the Wegovy to Mounjaro dose equivalent for switching purposes typically focuses on matching tolerability rather than maximum effect. Most UK prescribers recommend stepping down to Mounjaro 2.5mg when transitioning from any Wegovy dose, then titrating upward according to the standard Mounjaro schedule to minimise gastrointestinal side effects.

When considering the Wegovy to Mounjaro dose equivalent, it's crucial to understand that switching is not simply about finding a matching number. Your prescriber will assess your current Wegovy dose, treatment duration, weight loss progress, and side effect profile to determine the most appropriate starting dose of Mounjaro, subject to clinical approval.

Why Direct Dose Matching Isn't Recommended

The Wegovy to Mounjaro dose equivalent cannot be determined through simple arithmetic because tirzepatide's dual-agonist mechanism produces different metabolic effects at lower doses than semaglutide requires for comparable outcomes[2]. Starting Mounjaro at a lower dose than your current Wegovy strength allows your body to adapt to the new medication's receptor profile, reducing the risk of nausea, vomiting, and other common GLP-1 side effects that affect up to 44% of patients during dose escalation[3].

Wegovy to Mounjaro Dose Equivalent Chart: All UK Strengths

When evaluating the Wegovy to Mounjaro dose equivalent for each available strength, UK clinical guidance typically recommends restarting at Mounjaro 2.5mg regardless of your current Wegovy dose, then following the standard four-week titration schedule. This conservative approach, endorsed by the MHRA's prescribing guidance, prioritises patient safety and treatment adherence over attempting to maintain an equivalent therapeutic level during the switch.

For patients on Wegovy 0.25mg or 0.5mg (early titration doses), the Wegovy to Mounjaro dose equivalent starting point remains Mounjaro 2.5mg for four weeks, followed by escalation to 5mg. Those on Wegovy 1mg may similarly begin with Mounjaro 2.5mg, though some prescribers may consider starting at 5mg in patients who have demonstrated excellent tolerability. Patients established on Wegovy 1.7mg or the maximum 2.4mg dose will still typically restart at Mounjaro 2.5mg to allow physiological adaptation to tirzepatide's dual-agonist mechanism[1].

The Wegovy to Mounjaro dose equivalent pathway prioritises gradual escalation: 2.5mg for four weeks, then 5mg, 7.5mg, 10mg, 12.5mg, and finally 15mg if needed, with each increase spaced at least four weeks apart. This structured approach, validated in the SURPASS clinical trial programme, achieved average weight loss of 15% body weight at the 10mg maintenance dose and up to 20.9% at 15mg over 72 weeks[2].

Switching from Wegovy to Mounjaro: Wegovy to Mounjaro Dose Equivalent Protocol

The practical process of switching involves timing your final Wegovy dose and first Mounjaro dose appropriately. Since both medications are administered weekly, most UK prescribers recommend starting Mounjaro 2.5mg one week after your last Wegovy injection, regardless of the Wegovy to Mounjaro dose equivalent you might expect based on your previous strength. This one-week gap prevents overlapping GLP-1 receptor activity whilst maintaining sufficient drug levels to avoid withdrawal of glycaemic control or appetite suppression.

During the transition, patients should monitor for changes in appetite, blood glucose levels (if diabetic), and gastrointestinal symptoms. The Wegovy to Mounjaro dose equivalent starting dose of 2.5mg is intentionally conservative—approximately 50% lower than Mounjaro's typical maintenance doses—to allow your body to adjust to tirzepatide's additional GIP receptor agonism, which affects insulin secretion and fat metabolism differently than semaglutide alone[3].

Clinical Considerations During the Wegovy to Mounjaro Dose Equivalent Transition

When switching based on the Wegovy to Mounjaro dose equivalent protocol, some patients experience a temporary plateau in weight loss during the first 4-8 weeks as the body adapts to the new medication. This is physiologically normal and does not indicate treatment failure. Clinical data from patients switching between GLP-1 therapies show that weight loss typically resumes once the Mounjaro dose reaches 7.5mg or higher, with many patients ultimately achieving greater total weight reduction than they experienced on Wegovy alone[2]. Your prescriber will monitor your progress and may adjust the titration schedule based on your individual response and tolerability.

Wegovy Dose Recommended Mounjaro Starting Dose Titration Timeline Cured Pharmacy Price
0.25mg (Week 1-4) 2.5mg Start 2.5mg, increase to 5mg after 4 weeks From £145.00
0.5mg (Week 5-8) 2.5mg Start 2.5mg, increase to 5mg after 4 weeks From £145.00
1mg (Week 9-12) 2.5mg or 5mg* Increase every 4 weeks: 5mg → 7.5mg → 10mg From £145.00
1.7mg (Week 13-16) 2.5mg Increase every 4 weeks: 5mg → 7.5mg → 10mg → 12.5mg From £145.00
2.4mg (Maintenance) 2.5mg Increase every 4 weeks up to 15mg if needed From £145.00
Wegovy (any dose) Mounjaro 2.5mg Standard protocol: restart titration regardless of previous dose From £109.00 (Wegovy)

Wegovy to Mounjaro Dose Equivalent: Side Effect Profile Comparison

Understanding the side effect differences is crucial when considering the Wegovy to Mounjaro dose equivalent transition. Both medications share common GLP-1-related adverse effects including nausea, vomiting, diarrhoea, and constipation, but their incidence and severity can differ due to tirzepatide's dual-agonist mechanism[3]. In the SURPASS-2 trial comparing the two medications directly, nausea occurred in 22% of Mounjaro patients versus 18% on Wegovy, whilst vomiting affected 10% versus 9% respectively—clinically similar rates that suggest the Wegovy to Mounjaro dose equivalent starting approach of 2.5mg is appropriately cautious.

The Wegovy to Mounjaro dose equivalent protocol's gradual titration helps minimise these effects. Patients who experienced significant gastrointestinal side effects on Wegovy may find Mounjaro equally challenging, whilst those who tolerated Wegovy well typically transition smoothly. Importantly, the additional GIP agonism in Mounjaro may offer metabolic advantages—including improved insulin sensitivity and lipid profiles—that some patients find beneficial despite similar side effect rates[1].

Cost Comparison: Wegovy to Mounjaro Dose Equivalent UK Pricing

When evaluating the Wegovy to Mounjaro dose equivalent from a cost perspective, pricing varies by supplier and dose strength across the UK private market. At Cured Pharmacy, Mounjaro is available from £124.99 per pen, with transparent pricing displayed before your clinical consultation—no hidden fees or surprise charges after approval. This represents competitive UK pricing for genuine, MHRA-licensed tirzepatide supplied by a GPhC-registered pharmacy.

The Wegovy to Mounjaro dose equivalent cost analysis should account for the full titration schedule. Since most patients switching from any Wegovy dose restart at Mounjaro 2.5mg, initial monthly costs may be lower than your previous Wegovy expense, particularly if you were on the higher 1.7mg or 2.4mg strengths. However, as you titrate upward through 5mg, 7.5mg, 10mg, and potentially 12.5mg or 15mg, the cost per pen increases accordingly. Cured Pharmacy offers a first-order discount of £124.99 using code Weightlossnew, reducing your initial supply cost and making the Wegovy to Mounjaro dose equivalent transition more affordable.

Long-Term Value of the Wegovy to Mounjaro Dose Equivalent Switch

Beyond immediate pricing, the Wegovy to Mounjaro dose equivalent switch may offer superior long-term value if you achieve greater weight loss with Mounjaro, potentially reaching your goal weight faster and reducing total treatment duration. Clinical trial data showed that Mounjaro 15mg produced 20.9% average body weight reduction versus 14.9% with Wegovy 2.4mg over the same period[2], suggesting that despite potentially higher per-pen costs at maintenance doses, the enhanced efficacy could result in fewer total months of treatment required. This cost-benefit calculation is highly individual and should be discussed with your prescriber during your consultation at Cured Pharmacy.

Faq

What is the exact Wegovy to Mounjaro dose equivalent for 0.5mg Wegovy?
There is no direct milligram equivalent, as the medications have different mechanisms. UK clinical guidance recommends starting Mounjaro 2.5mg when switching from any Wegovy dose, including 0.5mg, then titrating upward every four weeks based on tolerability and response.
Can I switch directly from Wegovy 2.4mg to Mounjaro 15mg using a Wegovy to Mounjaro dose equivalent?
No—this is not recommended. Even when switching from the maximum Wegovy dose, you should restart at Mounjaro 2.5mg and follow the standard titration schedule to minimise side effects and allow your body to adapt to tirzepatide's dual-agonist mechanism.
How long should I wait between my last Wegovy dose and first Mounjaro dose when following the Wegovy to Mounjaro dose equivalent protocol?
Most UK prescribers recommend waiting one week after your final Wegovy injection before starting Mounjaro 2.5mg. This prevents overlapping GLP-1 activity whilst maintaining therapeutic drug levels during the transition.
Will I lose the weight loss progress I made on Wegovy when switching to the Wegovy to Mounjaro dose equivalent starting dose?
Most patients maintain their weight loss during the transition, though some experience a temporary plateau in the first 4-8 weeks. Weight loss typically resumes once Mounjaro is titrated to 7.5mg or higher, with many patients ultimately achieving greater total reduction than on Wegovy alone.
Is the Wegovy to Mounjaro dose equivalent the same for people with type 2 diabetes versus obesity only?
The starting dose protocol is the same—Mounjaro 2.5mg for four weeks regardless of indication—but patients with type 2 diabetes require closer blood glucose monitoring during the switch, as tirzepatide's dual-agonist mechanism may affect glycaemic control differently than semaglutide.
Does the Wegovy to Mounjaro dose equivalent change if I experienced severe side effects on Wegovy?
If you had significant gastrointestinal side effects on Wegovy, your prescriber may recommend an even slower Mounjaro titration schedule, potentially staying at 2.5mg for longer than four weeks before increasing. The Wegovy to Mounjaro dose equivalent starting point remains 2.5mg, but escalation timing becomes more individualised.
Can I get Mounjaro at the Wegovy to Mounjaro dose equivalent through the NHS?
Mounjaro is available through the NHS for type 2 diabetes, but NHS weight management access is currently limited to specialist services in certain areas. Private prescriptions through UK-registered pharmacies like Cured Pharmacy offer wider availability, with transparent pricing from £124.99 and clinical assessment by UK prescribers.
What happens if the Wegovy to Mounjaro dose equivalent starting dose of 2.5mg doesn't control my appetite as well as my previous Wegovy dose?
Some appetite increase during the first few weeks is normal as you restart at a lower dose. This typically resolves once you titrate to 5mg or 7.5mg Mounjaro. If appetite remains poorly controlled, contact your prescriber—they may adjust your titration schedule or reassess whether Mounjaro is the right option for you.
