How it works

Quieter hunger, all week.

Semaglutide acts like GLP-1, a hormone your gut already makes after you eat. In clinical trials, weight loss was reported alongside diet and exercise. Results vary.

1AppetiteLess hungryIt turns down the “I’m hungry” signal.
2FullnessSatisfied soonerSmaller portions start to feel like enough.
3DigestionSlower, steadierFood leaves your stomach more slowly, so you stay full for longer.

Other options

A pen that works on two hormones, too.

Mounjaro acts on GLP-1 and GIP. Your doctor recommends what fits, and you can change it later.

Questions

Before you start.

Who can take it?

Wegovy is approved in Japan for obesity disease. Your doctor decides whether it suits you, from your BMI, your health and what you’ve tried with diet and exercise. Even with a high BMI, treatment may not be right for you.

Who shouldn’t take it?

It isn’t for anyone pregnant, breastfeeding or planning a pregnancy, anyone with type 1 diabetes or a history of pancreatitis, or anyone with a personal or family history of medullary thyroid cancer or MEN2. Tell your doctor about any allergies and every medicine you take.

How do I inject it?

Once a week, on the same day, at any time. Inject under the skin of your stomach, thigh or upper arm, and change the spot each week. Each pen is one dose, and a step-by-step guide comes with it.

What if I miss a dose?

If your next dose is 2 or more days away, take it when you remember. If it’s less than 2 days away, skip it and go back to your usual day. Never take two doses at once.

Can I take it if I’m on the pill?

Yes. Always tell your doctor you take the pill. Bad sickness or diarrhoea can stop the pill being absorbed properly.

Can I switch to Mounjaro?

Yes, with your doctor. Follow-ups are free, so it’s a conversation, not a new start.

What are the side effects?

The most common are nausea, diarrhoea and constipation, especially when you start or step up a dose, and they often settle. Get help straight away for severe stomach pain that doesn’t go away: it may be pancreatitis.

When am I charged?

Consults are free, first and follow-up. You pay for medicine only once a doctor prescribes it. If medicine isn’t right for you, you pay nothing.
