Switching weight‑loss medication providers can feel like a big decision. Whether it’s because of rising costs, supply delays, lack of clinical support, or a desire for a more structured programme, many people assume it’s complicated. In reality, with the right guidance, switching providers can be much simpler and smoother than you might expect.
What to consider before switching
Before making the switch, take a moment to reflect on your current treatment. Are you happy with how it’s going? That includes your weight loss progress, how the medication makes you feel, your current dose, and any side effects you've experienced.
Think about when you last had an injection. If some time has passed, your new provider may recommend starting from a lower dose again to keep things safe.
You should also check whether your new provider supports the medication you're using or want to move to, such as Wegovy, Mounjaro, or Saxenda.
Finally, make sure the provider offers proper clinical support. Look for things like access to licensed prescribers, CQC registration, follow-ups, side-effect guidance, and helpful tools to track your weight and progress. All of these make the switch smoother and more effective.

Step‑by‑step: How to switch your provider
Thinking of switching providers? Whether you’re moving from another clinic, a digital service, or even the NHS, the process is usually simpler than you might think.
Here’s how it works at Voy:
1. Choose your new provider
Find a provider that offers more than just prescriptions. At Voy, you’ll get expert clinician support, side-effect management, and personalised coaching, all through an easy-to-use app.
2. Complete a medical questionnaire
You’ll be asked about your height, weight, medical history (including any conditions or medications), and whether you’re already on weight loss treatment. If so, you’ll need to confirm which medication you’re using (e.g. Wegovy or Mounjaro), your current dose, and the date of your last injection.
3. Confirm your plan and make payment
Once your initial eligibility is confirmed, you’ll select your subscription and complete payment to secure your place and begin the switch.
4. Submit verification documents
You’ll be asked to upload three things:
- A full-length body photo
- Photo ID
- Proof of your current treatment
Accepted proof includes a previous prescription, a photo of your medication packaging with the dispensing label, or an invoice from a weight loss provider. The document must clearly show your full name, the prescribed dose, and be dated within the last 8 weeks.Here are some tips to correctly complete approval tasks.
5. Clinical review
A licensed clinician will review all the information you’ve submitted to ensure the medication to determine the safest and most appropriate dose for you. If approved, you’ll receive confirmation and your delivery will be scheduled.
6. Start your new treatment
Begin ideally the same day of the week as your previous injection to maintain consistency. There should be a 7-day gap from your last dose, whether you’re switching medications or continuing the same one.
7. Monitor progress and check in
Use your provider’s app (like Voy’s) to log your injections, track weight, appetite and side effects, and get direct support from a clinician whenever needed.
Why people switch providers
There are plenty of valid reasons people decide to change weight loss providers. Rising costs or sudden price hikes can make ongoing treatment harder to sustain. Others experience long delays, inconsistent deliveries, or unhelpful customer service that leaves them feeling unsupported.
Some people switch because they want more reliable, personalised care. This might include having the same coach check in regularly, fast access to a clinician when needed, or a user-friendly app to track weight, appetite, and side effects.
Positive reviews from friends, colleagues, or family members can also influence the decision to move to a more trusted provider.
Side effects support at Voy
"If you're using Voy and you experience any side effects, rest assured that our expert clinicians are just a message or phone call away. They can adjust your dose, prescribe medication to ease your symptoms, or simply offer reassurance.
Everyone responds differently to weight loss treatment and we'll help you find what feels right for you."
Others may be moving from NHS care to a private clinic for more flexibility, or looking for a provider that offers structured support, coaching, and long-term plans.
At Voy, you’ll get all of this. You’ll have one consistent coach, quick access to clinicians when needed, reliable delivery, and in-app tools to help you stay on track. Whether you are looking for better support, affordability, or more structure, switching to the right provider can make a real difference.
Can you switch between medications?
Yes. Switching between GLP-1 medications like Mounjaro and Wegovy is safe when done under clinical guidance. At Voy, we support structured transitions based on your treatment history and goals.
You’ll need to wait at least 7 days after your last injection before starting a new medication to avoid overlap.
At Voy, we’ll recommend the most appropriate starting dose for you, guided by clinical data and your treatment history, including previous medication, last dose and any side effects.
Safety and continuity considerations
Switching providers should never put your progress or safety at risk. Make sure your new provider is GPhC-registered, offers clinician-led care, and reviews your full medication history before recommending a treatment. Safe switching requires real clinical oversight and ongoing support.
