Our UK-registered prescribers assess every patient individually to ensure Mounjaro (tirzepatide) is safe and appropriate for your weight loss goals.

How Mounjaro (Tirzepatide) Works for Weight Loss

Mounjaro contains tirzepatide, the first dual GIP/GLP-1 receptor agonist licensed by the MHRA for weight management in the UK [1]. Unlike single-pathway treatments such as semaglutide, tirzepatide activates both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, producing more pronounced effects on appetite regulation and metabolic control.

In the SURPASS-3 clinical trial, participants receiving the 15mg maintenance dose of tirzepatide achieved an average body weight reduction of 22.5% over 72 weeks [1]. This dual-action mechanism slows gastric emptying, reduces hunger signals, and improves insulin sensitivity, helping patients achieve sustained weight loss when combined with dietary and lifestyle modifications [2].

Mounjaro Dosing Schedule and Administration

Mounjaro is administered as a once-weekly subcutaneous injection using the KwikPen device, which delivers pre-measured doses without the need for manual preparation. Treatment begins with a 2.5mg starter dose for the first four weeks to minimise gastrointestinal side effects, then increases gradually every four weeks until reaching your maintenance dose [3].

The dose escalation typically follows this schedule: 2.5mg for four weeks, then 5mg, 7.5mg, 10mg, 12.5mg, and finally 15mg if clinically appropriate. Your UK prescriber will determine the optimal maintenance dose based on your tolerance, weight loss progress, and any side effects experienced during titration. Each pen contains a single dose and should be stored in the refrigerator between 2°C and 8°C until use [3].

How to Inject Mounjaro Safely

Inject Mounjaro into the abdomen, thigh, or upper arm, rotating injection sites each week to prevent lipodystrophy. The pen should be at room temperature before injection, and you should inspect the solution through the viewing window to ensure it's clear and colourless. Never share pens between patients, even if the needle is changed, as this poses serious infection risks.

Mounjaro vs Wegovy: Clinical Efficacy Comparison

Both Mounjaro and Wegovy are injectable weight loss treatments licensed in the UK, but they differ significantly in mechanism and clinical outcomes. Wegovy contains semaglutide, a GLP-1 receptor agonist, while Mounjaro's tirzepatide activates both GIP and GLP-1 pathways. Head-to-head trials demonstrate that tirzepatide produces greater average weight loss than semaglutide at comparable treatment durations [4].

In the STEP 1 trial, participants on semaglutide 2.4mg achieved an average weight reduction of 14.9% over 68 weeks [5]. By comparison, the SURMOUNT-1 trial showed tirzepatide 15mg delivered an average 22.5% reduction over 72 weeks [1]. Both medications require gradual dose escalation and are subject to prescriber approval following clinical assessment. Your UK prescriber will consider your medical history, current medications, and weight loss goals when recommending the most appropriate treatment.

Which Treatment Suits Your Needs?

Patients with a history of gastrointestinal sensitivity may tolerate the slower titration schedule available with semaglutide-based treatments, while those seeking maximum efficacy may be better candidates for tirzepatide. Cost considerations, injection frequency, and individual response all influence treatment selection, which is why every prescription at Cured Pharmacy follows a thorough clinical assessment by our UK-registered prescribers.

Common Side Effects and How to Manage Them

The most frequently reported side effects of Mounjaro are gastrointestinal, including nausea, diarrhoea, vomiting, constipation, and abdominal discomfort. These effects are typically mild to moderate and diminish as your body adapts to the medication, particularly if you follow the recommended dose escalation schedule [3]. Eating smaller, more frequent meals and avoiding high-fat foods can help reduce nausea during the initial weeks.

Rare but serious adverse effects include pancreatitis, gallbladder disease, and hypoglycaemia (particularly if used with insulin or sulfonylureas). Contact your GP or prescriber immediately if you experience severe abdominal pain, persistent vomiting, or signs of an allergic reaction such as rash, swelling, or difficulty breathing. Mounjaro is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 [3].

Who Can Buy Mounjaro Online UK and Eligibility Criteria

To buy Mounjaro online UK, you must meet MHRA-approved prescribing criteria, which typically include a body mass index (BMI) of 30 kg/m² or above, or 27 kg/m² with at least one weight-related comorbidity such as type 2 diabetes, hypertension, or obstructive sleep apnoea. Your UK prescriber will assess your medical history, current medications, and contraindications during the free online consultation at Cured Pharmacy.

Mounjaro is not suitable for everyone. It is contraindicated in pregnancy, breastfeeding, patients under 18 years of age, and those with a history of severe gastrointestinal disease or certain endocrine tumours. If you have a history of diabetic retinopathy, kidney impairment, or pancreatitis, your prescriber will evaluate whether Mounjaro is safe for you. All prescriptions are issued at the clinical discretion of our UK-registered prescribers, including Superintendent Pharmacist Tarun Kumar (GPhC 2233073).

The consultation takes under three minutes and covers your medical history, current medications, allergies, and weight loss goals. You'll be asked about previous weight management attempts, any history of eating disorders, and relevant comorbidities. If approved, your prescription is sent electronically to our dispensary, and your medication is dispatched in discreet packaging with next-day delivery options available across the UK.
