The same medicine, without the needle
Oral semaglutide was approved in the UK in 2026, which makes it the first weight loss treatment of its kind you can take as a daily tablet. The active medicine is the one we have prescribed as a weekly injection for years — what changes is how it gets into you, and what that asks of your daily routine.
Appetite first, willpower second
Semaglutide mimics GLP-1, a hormone your gut already makes after eating. It acts on the part of the brain that governs hunger and slows how quickly the stomach empties.
In trials published in The Lancet, the 50mg dose produced around 15% weight loss against 2% for placebo. Combined with changes to diet and activity, patients may expect to lose up to 14% of body weight over twelve to eighteen months. Both figures come from trial populations who also had clinical support, and individual results vary.
Numbers from trials describe what happened to a group of people under study conditions. They are a reasonable guide to what treatment can do, not a prediction about you — which is part of what the consultation is for.
A daily tablet
Taken every day rather than once a week. The dose starts low and steps up over several weeks, the same principle as the injection — a slow increase is what keeps side effects tolerable.
Timing matters
On an empty stomach, with a small sip of water, then wait before anything else. Food, other drinks and other medicines all reduce how much of the dose is absorbed. In practice it becomes the first thing you do in the morning, before coffee.
Every day counts
A weekly injection forgives a forgetful day. A daily tablet doesn't. If routine is the thing you find hardest, the injection may genuinely suit you better — that is a conversation worth having before you choose.
No needles
Nothing to inject, store or dispose of. For people who have ruled out treatment because of the needle, or who travel constantly and would rather not carry a pen, this is the reason the tablet exists.
Around fourteen per cent of starting body weight over roughly a year, alongside diet and activity support. For someone starting at 100kg that is about fourteen kilograms — enough to move blood pressure, cholesterol and blood sugar, which is the point of treating weight as a medical problem.
Averages, not a promise. Individual results vary with dose, tolerance and how much of the wider plan you use — and a slower loss is not a failed one.
Our fee, then the pharmacy's price
We charge for the consultation and the follow-up. The medicine is dispensed by the pharmacy of your choice at their price — we don’t sell medications.

Prices shown are SignatureRx's, correct as of 7 July 2026. Medication is prescription-only and supplied following clinical assessment. You are free to use any UK pharmacy.
Treatment begins at the lowest dose and steps up over several months as your consultant adjusts it. The table shows the pharmacy’s price at every step, so you can see the whole range before you book rather than just the entry point.
The tablet is not automatically the better option
Which form suits you depends on your routine, your other medicines and how your stomach handles it. Both are assessed at your consultation, and you can change your mind later.
Where the tablet often wins
A strong dislike of needles. Frequent travel, or nowhere reliable to refrigerate a pen. A preference for a daily habit over a weekly event.
Where the injection often wins
Irregular mornings, shift work, or several other tablets already competing for the same empty stomach. One appointment with yourself a week is easier to keep than one every morning.
When neither is appropriate
A history of pancreatitis or gallbladder disease, certain thyroid conditions, an active eating disorder, pregnancy or planning one. Side effects are the same family as the injection — mostly digestive, plus hair loss while weight falls quickly; rare but serious ones include pancreatitis, gallbladder problems and NAION, an eye condition causing visual change. Follow-ups track your rate of weight loss, side effects, hydration, exercise and global wellbeing.
Decide which form suits you in the consultation, not before it
Thirty minutes with a Consultant Endocrinologist, and no obligation to start anything at all.
