If you're searching for mounjaro £20 off first order using code WEIGHTLOSSNEW, Cured Pharmacy offers genuine UK-licensed Mounjaro (tirzepatide) pens from £124.99 with transparent upfront pricing and a free clinical consultation. Our UK-registered prescribers assess your suitability online in under 3 minutes, and all orders include discreet next-day delivery across Northern Ireland.

How Mounjaro Works for Weight Loss

Mounjaro contains tirzepatide, the first dual GIP/GLP-1 receptor agonist licensed by the MHRA for chronic weight management in the UK [1]. Unlike older single-pathway treatments such as semaglutide, tirzepatide activates two natural hormone pathways that regulate blood sugar control, appetite suppression, and gastric emptying, producing greater clinical effects in trials.

In the SURMOUNT-1 trial, adults with obesity who received the 15mg maintenance dose achieved an average 22.5% body weight reduction over 72 weeks — significantly higher than semaglutide-based alternatives [1]. Participants also reported improved cardiometabolic markers, including reductions in HbA1c, blood pressure, and waist circumference [2].

Mounjaro is administered once weekly via a pre-filled KwikPen injection device. Treatment begins at a low starter dose (2.5mg) and gradually escalates every four weeks to minimise gastrointestinal side effects, with your UK prescriber determining the optimal maintenance dose based on your individual response and tolerability.

Mounjaro Pricing and Discount Eligibility in Northern Ireland

At Cured Pharmacy, Mounjaro starts from £124.99 for Northern Ireland patients, with the final price determined by your prescribed dose following a free online consultation. Our transparent pricing model means you see the exact cost before completing your clinical assessment — no hidden fees or surprise charges at checkout.

The £20 discount applies automatically to your first Mounjaro order when you complete a valid prescription consultation with our UK-registered clinical team. This offer is available exclusively to new patients in Northern Ireland and cannot be combined with other promotional codes or retrospectively applied to previous orders.

All Mounjaro prescriptions require clinical approval by a UK prescriber, who will review your medical history, current medications, weight loss goals, and any contraindications. If Mounjaro is not suitable based on your assessment, our prescribers may recommend alternative treatments such as semaglutide or liraglutide, subject to clinical appropriateness.

What's Included in Your Mounjaro Order

Every Mounjaro order from Cured Pharmacy includes free online consultation with a UK prescriber, genuine MHRA-licensed medication dispensed by our GPhC-registered pharmacy (9012511), discreet packaging with no external branding, tracked next-day delivery across Northern Ireland, and ongoing clinical support from our pharmacist team led by superintendent Tarun Kumar (GPhC 2233073).

Mounjaro vs Wegovy: Comparing Weight Loss Treatments

Both Mounjaro (tirzepatide) and Wegovy (semaglutide) are injectable GLP-1 receptor agonists licensed in the UK for chronic weight management, but they differ in mechanism, efficacy, and side effect profiles. Mounjaro activates both GIP and GLP-1 receptors, whilst Wegovy targets only the GLP-1 pathway [1][3].

Head-to-head trial data from SURPASS-2 demonstrated that tirzepatide produced significantly greater weight reduction compared to semaglutide 1mg in adults with type 2 diabetes, with the 15mg tirzepatide group achieving 5.5kg more weight loss on average over 40 weeks [3]. However, both medications require gradual dose escalation and carry similar gastrointestinal side effects, including nausea, vomiting, and diarrhoea.

Your choice between Mounjaro and Wegovy should be guided by your UK prescriber, who will consider your weight loss history, comorbidities, medication tolerability, and budget. Some patients may start with semaglutide-based treatments and switch to tirzepatide if weight loss plateaus or side effects become limiting.

Injectable vs Oral Weight Loss Options

Cured Pharmacy also offers oral semaglutide tablets (Wegovy Oral) for patients who prefer not to inject. Oral semaglutide requires daily dosing and must be taken on an empty stomach with specific timing restrictions, whereas injectable treatments offer once-weekly convenience. Clinical trials show injectable formulations produce slightly greater weight loss on average, though oral options remain effective for many patients [4].

Common Side Effects and How to Manage Them

The most frequently reported side effects of Mounjaro are gastrointestinal, including nausea (reported in up to 30% of patients), diarrhoea, vomiting, constipation, and abdominal discomfort [1]. These effects are typically mild to moderate, occur most commonly during dose escalation, and diminish over time as your body adjusts to the medication.

To minimise gastrointestinal symptoms, our prescribers recommend eating smaller, more frequent meals, avoiding high-fat or spicy foods, staying well-hydrated, and taking your injection on the same day each week. If nausea persists or worsens, your prescriber may slow the dose escalation schedule or consider alternative treatments.

Rare but serious side effects include pancreatitis, gallbladder disease, hypoglycaemia (especially in patients taking other diabetes medications), and thyroid C-cell tumours (observed in animal studies). Mounjaro is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. Always report any severe abdominal pain, persistent vomiting, or visual changes to your prescriber immediately.

How to Order Mounjaro from Cured Pharmacy

Ordering Mounjaro from Cured Pharmacy is straightforward and fully compliant with UK pharmacy regulations. Start by clicking 'Start Assessment' on our Mounjaro product page, then complete the free online consultation form, which takes under 3 minutes and covers your medical history, current medications, weight loss goals, and any contraindications.

A UK-registered prescriber will review your assessment within 24 hours (often sooner). If approved, your prescription is sent electronically to our GPhC-registered pharmacy, where our team dispenses genuine MHRA-licensed Mounjaro pens. We dispatch all Northern Ireland orders via tracked courier for next-day delivery in discreet, unbranded packaging.

If your prescriber determines Mounjaro is not clinically appropriate based on your assessment, they will explain why and may suggest alternative treatments such as Wegovy, Saxenda, or Orlistat. You will not be charged if your consultation is declined, and our clinical team is available by phone (+44 116 4646009) if you have questions about your assessment outcome.

Repeat Prescriptions and Ongoing Support

Mounjaro requires ongoing monitoring and repeat prescriptions every 4-12 weeks depending on your dose. Cured Pharmacy sends automated reminders before your medication runs out, and you can request repeat consultations through your online account. Our pharmacist team provides free advice on injection technique, side effect management, and treatment optimisation throughout your weight loss journey.

Alternative Weight Loss Treatments Available

If Mounjaro is not suitable or you prefer a different treatment approach, Cured Pharmacy offers a comprehensive range of MHRA-licensed weight loss medications. Wegovy (semaglutide) is a once-weekly injectable GLP-1 agonist that produces significant weight reduction in clinical trials, whilst Saxenda (liraglutide) is a daily injectable option for patients who prefer more gradual dose adjustments [2][4].

For patients seeking non-injectable alternatives, we dispense Orlistat (available as generic or branded Xenical), which works by blocking fat absorption in the digestive system. Orlistat requires a lower-fat diet to minimise side effects and is suitable for patients with a BMI over 28 (or over 25 with weight-related comorbidities). Alli is a lower-strength version available for patients with a BMI over 28.

Oral semaglutide tablets (Wegovy Oral) combine the efficacy of GLP-1 therapy with the convenience of a daily pill, though strict dosing instructions must be followed for optimal absorption. Your UK prescriber will recommend the most appropriate treatment based on your BMI, medical history, previous weight loss attempts, and personal preferences.

Has the price of Mounjaro gone up?

Yes. From 1 September 2025, Eli Lilly raised the UK list price of Mounjaro, so pharmacies now pay more for every pen. The Pharmaceutical Journal reports that the cost to pharmacies moved from a range of £92 to £122 a pen to £133 for the 2.5mg pen and £330 for the 12.5mg and 15mg pens. For the highest dose, RTÉ reports that Lilly put the monthly price at £330, up from £122, which is a rise of about 170%.

The increase applies to private prescriptions. The Pharmaceutical Journal reports that NHS commissioning of tirzepatide is unaffected by the change in list price. Lilly confirmed the change on 15 August 2025.

Lilly sets the list price, but each pharmacy sets its own price and may receive rebates, which is why the same pen can cost different amounts.
