Switching from MedExpress, Voy and Others to The Care Pharmacy

If you are considering switching weight loss treatment to The Care Pharmacy, you are already closer to a better experience than you might think. Moving providers does not mean restarting your journey. This guide explains exactly how switching works, what happens to your current dose, how your treatment continues without unnecessary interruption, and why thousands of patients have chosen to move their weight loss treatment to a GPhC-registered, pharmacist-led pharmacy that puts clinical care first.

Whether you are currently with MedExpress, Voy, or another online weight loss service and are looking for more support, more transparent pricing, or simply a pharmacy you can actually speak to — read on.

Why patients switch weight loss providers

The growth of online weight loss services in the UK means patients now have more choice than ever. But more choice also means more variation in the quality of care, the level of clinical oversight, and the day-to-day experience of being a patient on a GLP-1 treatment.

Based on what patients tell us when they come to The Care Pharmacy from other providers, the most common reasons for switching are consistent:

• Difficulty reaching a pharmacist or clinician. GLP-1 medicines like Mounjaro (tirzepatide) and Wegovy (semaglutide) come with side effects, dose escalation questions, and injection technique queries. Patients on automated or low-touch services sometimes find it hard to speak with someone clinical when they need to.
• Stock issues and supply delays. Supply constraints have affected many GLP-1 providers at various points. When stock runs out with no clear timeline, patients understandably look elsewhere.
• Pricing increases or unexpected charges. Some patients find their costs rise significantly after the introductory period, or encounter charges they were not expecting — for consultations, needles, delivery, or follow-up reviews.
• Wanting a pharmacy-first approach. Some patients start with a direct-to-consumer subscription service and later decide they want the governance and accountability of a proper registered pharmacy — with a named pharmacist, clinical oversight, and full dispensing accountability.
• First Dose Video Supervision. The Care Pharmacy offers supervised first injection sessions as standard, which some patients specifically seek out when they realise their current provider does not offer this level of support.

None of these reasons imply your previous provider was unsafe — many online services are GPhC-registered and operate responsibly. But your needs can change as your treatment progresses, and switching to a provider that better fits where you are now is a reasonable and common decision.

Is it clinically safe to switch weight loss providers?

For most patients who are established on a GLP-1 treatment, moving to a new provider does not require restarting on the lowest dose. The medication itself does not change between providers — a Mounjaro 7.5mg KwikPen dispensed by The Care Pharmacy is the same Eli Lilly product as one dispensed by any other GPhC-registered pharmacy in the UK. What matters is that your new prescriber has an accurate picture of your current treatment history before they prescribe.

A few principles apply across the board:

• Do not stop your current medication without confirming your new provider can prescribe before your next due dose. A gap in GLP-1 treatment can affect your progress.
• Bring an accurate record of your current dose, when you last injected, and any side effects you have experienced. This allows your new prescriber to make an informed decision.
• If you have had any significant changes to your health — new conditions, new medications, pregnancy — these must be declared in your new consultation regardless of what your previous provider was told.

What to bring when you switch to The Care Pharmacy

Switching is straightforward. You do not need a letter from your previous provider or a formal transfer of records. What helps most is arriving at your new consultation prepared with the following:

• Your current medication and dose strength (e.g. Mounjaro 7.5mg, Wegovy 1.0mg)
• The date of your last injection
• Your current weight and height (for BMI calculation)
• Any known medical conditions or allergies — including any diagnosed since you started treatment
• A list of all current medications, including over-the-counter treatments and supplements
• Any side effects you have experienced at your current dose

If you have any previous consultation records, a copy of your most recent prescription, or blood test results, these can be helpful but are not required. Our prescriber will carry out a thorough clinical assessment and may ask clarifying questions based on your answers.

How switching to The Care Pharmacy works

We have made the switching process as simple as possible. Here is what to expect from start to delivery:

What happens to your current dose when you switch?

This is the question most patients ask first. The good news is that, for the majority of patients who are established and tolerating their current dose, treatment can typically continue at the same strength with The Care Pharmacy following a clinical assessment.

You do not automatically need to restart at the lowest dose simply because you are switching pharmacies. The medication is the same product. What our prescriber needs to confirm is that you are clinically suitable to continue at your current dose — which is why the consultation matters.

There are scenarios where our prescriber might recommend a dose adjustment:

• If you have experienced significant side effects that were not fully resolved at your current dose
• If there has been a long gap in treatment (typically four or more weeks without a dose)
• If your health has changed in a way that warrants clinical review before continuing

The prescriber’s decision will always be based on what is clinically appropriate for you as an individual. Our goal is to continue your treatment with as little disruption as possible while ensuring we are prescribing safely.

First Dose Video Supervision at The Care Pharmacy

The Care Pharmacy offers a supervised first injection session as part of its weight loss service — a feature not consistently available across all online providers. Even if you are already experienced at injecting, booking a First Dose Video Supervision session when you switch to us provides a useful clinical checkpoint.

During the session, a member of our pharmacy team will:

• Walk you through correct injection technique for your specific pen (Mounjaro KwikPen, Wegovy FlexTouch, or other)
• Confirm correct storage and handling of your new order
• Answer any questions about side effects, dose timing, and what to do if you miss a dose
• Document the session in your patient record for ongoing clinical continuity

This service is offered at no additional cost as part of your treatment at The Care Pharmacy. You can book directly at thecarepharmacy.com/book-a-supervised-first-injection/.

Why patients choose The Care Pharmacy

The Care Pharmacy is a GPhC-registered UK pharmacy (registration number 9010308), not a technology platform with a pharmacy licence attached. That distinction matters when you are taking a weekly injectable prescription medicine over months or years.

Pricing at The Care Pharmacy — and what is included

One of the most common surprises patients encounter when switching providers is discovering what their previous service did and did not include. At The Care Pharmacy, our treatment prices are all-inclusive. There are no hidden extras at checkout.

Every order from The Care Pharmacy includes:

• ✓Clinical consultation reviewed by our pharmacist prescriber
• ✓Prescription fee
• ✓Pen needles and alcohol swabs
• ✓Sharps disposal container (with your first order)
• ✓Free next-day tracked delivery in temperature-controlled packaging
• ✓Access to our clinical team throughout treatment

Prices shown are for the starter dose. Higher doses are priced accordingly — see our full weight loss treatment pages for current pricing at each dose strength.

Comparing weight loss providers: what to look for

With dozens of services now offering GLP-1 weight loss treatments in the UK, it can be difficult to know what distinguishes one from another. Beyond price, the factors that matter most for long-term safety and results are clinical governance, prescriber accountability, and the quality of ongoing support.

When evaluating any provider — including The Care Pharmacy — consider asking:

• Is the pharmacy GPhC-registered? You can check any UK pharmacy on the GPhC register. A valid registration number and a named superintendent pharmacist are non-negotiable.
• Is my consultation reviewed by a qualified prescriber? Not all services use pharmacist prescribers or doctors to review consultations. Some use non-prescribing staff or rely heavily on automated systems. Your prescriber is legally accountable for the prescription — know who they are.
• What support is available if I have a problem? Side effects are common with GLP-1 treatments, particularly during dose increases. Is there a pharmacist you can speak to, or only a messaging system with a 48-hour response time?
• What is included in the price? See the table above. Always ask for a full breakdown before committing.
• Is the medication genuine? Only purchase from GPhC-registered UK pharmacies sourcing from licensed wholesalers. The MHRA has previously warned about counterfeit GLP-1 products circulating through unregistered sources.
