Can Your GP Prescribe Mounjaro Privately?

You've asked your GP and the answer was 'no', this is why

Picture the scene: you've done the reading, you meet the BMI criteria, and you bring it up at your next appointment. Your GP listens, nods, and then explains that prescribing Mounjaro falls outside what they can currently offer you. That's not evasion. It reflects how NHS general practice actually works right now.

NHS GP practices are commissioned to prescribe within NHS frameworks. Tirzepatide sits outside routine NHS prescribing for most patients until they meet the phased rollout criteria, and even then, many practices are still setting up the required wraparound support. From April 2026, GP practices can prescribe under the new contract, but participation is optional and availability varies enormously by area. You can read more about the NHS rollout on our overview of whether GPs can prescribe Mounjaro on the NHS.

Private prescribing is a different matter. If you're wondering whether your doctor can prescribe Mounjaro privately, the short answer is that a GP can do so if they hold a separate private prescribing licence and are satisfied it is clinically appropriate. The catch is that many GPs simply don't hold this licence or have chosen not to operate in a private capacity. Some private GP clinics do offer this, typically at consultation fees on top of medicine costs. It is worth asking your own doctor directly, the answer varies.

What 'private prescribing' actually requires from any doctor

Regardless of the setting, the legal and clinical requirements are the same. Mounjaro is a Prescription-Only Medicine under the Human Medicines Regulations 2012, which means a prescriber (GP, pharmacist independent prescriber, or specialist) must assess your eligibility before issuing a prescription. No legitimate route skips that step.

At minimum, a prescriber will want to confirm your BMI, review any relevant medical history, check for contraindications (certain thyroid conditions, a history of pancreatitis, and others), and consider interactions with existing medicines. If you are on an oral contraceptive, for instance, NHS England advises adding a non-oral method for the first four weeks of treatment and after each dose increase, because absorption may be reduced. A prescriber who doesn't raise this question is a red flag.

For a fuller picture of who typically qualifies, our page on what BMI is needed for Mounjaro privately covers the licensed eligibility thresholds in detail. The short version: adults with a BMI of 30 or above, or 27 and above with a weight-related condition such as high blood pressure, type 2 diabetes or obstructive sleep apnoea, may be eligible, subject to a prescriber's full assessment.

The regulated alternative when your GP can't help

If your GP isn't the right door, GPhC-registered online pharmacies with their own independent prescribers are a well-established private route, and our guide to buying Mounjaro privately explains what to look for and what to watch out for when choosing one. The prescriber reviews your consultation, checks your identity and verifies your weight (a real clinician reads your answers, not automated software) and if treatment is appropriate, a prescription is issued and the medicine is dispensed from a regulated UK pharmacy.

This is how nume works. Our pharmacy is GPhC-registered (you can verify us directly at the GPhC register, registration number 9012878). Consultations are reviewed the same day by a GPhC-registered Independent Prescriber, and if approved, your Mounjaro ships the same working day via tracked DPD delivery.

One practical note: Mounjaro pens are stored in the fridge, ideally somewhere with a consistent temperature, most people tuck them in the door alongside everyday items. Your prescriber will point you to the patient information leaflet for the exact storage window if you need to take it out temporarily.

Cost: what to expect regardless of the route

Private prescribing, whether through a GP clinic or an online pharmacy, carries costs. The medicine itself is not cheap: following Eli Lilly's UK price adjustment in September 2025, typical private monthly costs have ranged roughly £149 to £375 depending on the dose and provider, as widely reported. A private GP may also charge a consultation fee separately from the prescription cost, so it is worth asking upfront what is and isn't included.

For a clear picture of what affects the monthly figure, our guide to Mounjaro costs breaks down what private providers typically include, and what some quietly leave out. The NICE appraisal of tirzepatide (TA1026) sets out the eligibility criteria that any prescriber should be working to, which is useful background when you're comparing services.
