- Want a weekly routine?Injections are taken just once a week, so there's no daily tablet to remember.

Frequently asked questions
GLP-1 medications mimic a hormone your body naturally produces to help regulate appetite. They work by helping you feel fuller for longer, which can reduce how much you eat over time.
Many people with a BMI of 25 or above are eligible for weight loss medication. Eligibility also depends on your overall health. A clinician will review your medical history, any existing conditions, and your current medications to assess whether treatment is suitable for you.
GLP-1 medications are taken as a weekly injection using a pre-filled pen. You inject it yourself into your stomach, thigh, or upper arm. The pen is designed to be straightforward to use, and we'll explain exactly how before you start with guides and videos.
The most common side effects are nausea, diarrhoea, and constipation. These are usually mild and tend to ease as your body adjusts. Starting on a lower dose and increasing gradually helps reduce the likelihood of side effects, and we'll support you with it. If anything concerns you, get in touch and we'll help.
There's no fixed time limit. Treatment length depends on your progress and what your clinician recommends. Most people take GLP-1 medication alongside lifestyle changes like diet and exercise. If you stop, some weight regain is possible, which is why ongoing support is an important part of your treatment plan.
Start by completing your online consultation. Answer a few questions about your health, and a clinician will review your answers. If treatment is suitable for you, your medication will be prescribed and delivered to your home.
The consultation is completed online and takes around 2 to 5 minutes. You'll answer questions about your health history, current medications, and weight loss goals. You don't need to speak to anyone or attend any kind of appointment. A clinician reviews your answers and decides whether treatment is suitable for you.
No. The entire process is online, from consultation through to delivery. There are no in-person appointments required.
Yes. Your medication arrives in plain, unmarked packaging with nothing on the outside to indicate what's inside. There's no need to visit a pharmacy or collect anything in person.
The price covers your medication, delivery, and ongoing support from our team of experts. Everything is included, with no hidden fees.
GLP-1 medications are started at a lower dose and increased gradually as your body adjusts. Many people see meaningful results without reaching the highest dose, and you only move up when you and your clinician agree you're ready. The price reflects whichever dose you're taking, so you're always in control of both your treatment and your costs.
You pay when you complete your order. If a clinician decides treatment is not suitable for you, we'll automatically refund you in full.
No. There's no minimum term or lock-in contract. You can stop treatment at any time.
Some GLP-1 medications are available on the NHS, but access is currently very limited and typically requires a referral to a specialist weight management service, with significant waiting times. MedExpress offers a private alternative, meaning you can access treatment through an online consultation.
Once you start treatment, you'll have ongoing access to our clinical team. We'll also send you tailored guides and videos as your treatment progresses to help you get the most from it. You can get in touch at any time if you have questions, need advice, or want to review your treatment.
You can get in touch with our clinical team through our website. We aim to respond as quickly as possible. If you're experiencing a medical emergency, call 999.
Switching treatment is straightforward. You can explore your options on our website, or get in touch if you'd like some support finding the right fit.
Yes, and it's more common than you might think. If your current treatment isn't giving you the results you hoped for, or doesn't suit you, our clinical team can review your options and recommend an alternative if appropriate.
Let us know as soon as possible. Get in touch through our website and we'll make sure your treatment is still right for you.
