How to Get Mounjaro in the UK (2026)

As of 2026, Mounjaro (tirzepatide) is available on the NHS for the treatment of type 2 diabetes. However, it is not yet routinely available on the NHS for weight management alone. NICE (the National Institute for Health and Care Excellence) has approved tirzepatide for type 2 diabetes, and appraisals for its use as a weight management treatment are ongoing. This means that if you want to use Mounjaro specifically for weight loss, you will currently need to go through the private prescription route. This may change in the future as NICE completes its assessment, but for now, private purchase is the primary option for weight management patients in the UK.

The most common way to get Mounjaro for weight loss in the UK is through a private prescription from an online pharmacy or weight management clinic. This is a legitimate and regulated process. A registered prescriber (usually a doctor or pharmacist prescriber) will assess your suitability based on your BMI, medical history, current medications, and weight loss goals. If they determine that Mounjaro is appropriate for you, they will issue a private prescription and the pharmacy will dispense the medication. The entire process, from consultation to delivery, can often be completed within a few days. You do not need a referral from your GP, although it is always a good idea to inform your GP that you are taking Mounjaro so they can update your medical records.

The typical process for ordering Mounjaro from a private online pharmacy involves these steps:

• Step 1: Complete a health questionnaire. You will answer questions about your height, weight, medical history, current medications, allergies, and why you want to try Mounjaro.
• Step 2: Prescriber review. A registered prescriber reviews your answers. Some pharmacies may require a video or phone consultation, while others assess based on the questionnaire alone. The prescriber checks that Mounjaro is safe and appropriate for you.
• Step 3: Prescription issued. If approved, the prescriber issues a private prescription. If not approved, you will be told why and may be offered alternative options.
• Step 4: Payment and dispatch. You pay for the medication and it is dispatched with cold-chain delivery (temperature-controlled packaging) to ensure the medication arrives in safe condition.
• Step 5: Ongoing support. Many pharmacies offer follow-up consultations, dose adjustments, and support throughout your treatment.

Not all online pharmacies are equal. When choosing where to buy Mounjaro, look for the following:

• GPhC registration: The pharmacy must be registered with the General Pharmaceutical Council. You can verify their registration on the official GPhC register. All pharmacies listed on WeightCompare are GPhC-verified.
• Genuine clinical consultation: A legitimate pharmacy will require a proper health assessment before prescribing. Be wary of any service that allows you to buy Mounjaro without a consultation.
• Cold-chain delivery: Mounjaro must be stored at 2-8 degrees Celsius. The pharmacy should use temperature-controlled packaging for delivery.
• Transparent pricing: The price should clearly state what is included (consultation fee, medication, delivery, needles). Some pharmacies bundle everything; others charge separately.
• Contact details and support: A reputable pharmacy will have clear contact information, a UK-based customer support team, and offer ongoing prescriber access for dose adjustments.

Mounjaro prices vary significantly between pharmacies and depend on the dose. As a general guide for a 4-week supply (one pen):

• 2.5mg: £130 - £230
• 5mg: £140 - £240
• 7.5mg: £150 - £250
• 10mg: £160 - £270
• 12.5mg: £165 - £290
• 15mg: £170 - £320

These are approximate ranges. Prices change frequently as pharmacies compete for customers. The difference between the cheapest and most expensive pharmacy can easily be £100 or more per month. Over a 6-month treatment course, that adds up to savings of £600+.

Here are practical ways to reduce the cost of your Mounjaro treatment:

• Compare prices regularly. Pharmacy prices change frequently. Check our comparison table each time you reorder.
• Look for bundle deals. Some pharmacies offer discounts when you buy multiple months at once or subscribe to a regular delivery plan.
• Check what is included. A pharmacy advertising a lower headline price may charge extra for the consultation, delivery, or needles. Compare the total cost, not just the medication price.
• Consider subscription plans. Several pharmacies offer monthly subscription pricing that works out cheaper than one-off purchases.
• Do not overpay for higher doses. The price difference between doses varies by pharmacy. Some pharmacies charge similar prices across all doses, while others have steep increases for higher doses.
