What is Ozempic?

Ozempic, containing the active ingredient Semaglutide, is a prescription medication used to treat type 2 diabetes mellitus (T2DM). Although it is used for diabetes management, it has been found to cause weight loss as a side effect.

Ozempic should be used with a balanced diet and regular exercise when prescribed.

What is Ozempic (Semaglutide) used for?

Ozempic is a medicine that helps people with type 2 diabetes. The active ingredient, Semaglutide, helps keep blood sugar levels in the right range.

Studies showed that people using this medicine often lost weight as a side effect.

A new medicine called Wegovy, also containing Semaglutide, is now available in the UK. Semaglutide, sold under the name Wegovy, is specifically licensed and used for weight loss, not diabetes.

What is the difference between tablets and injections?

Semaglutide is available as injections as well as tablets. Semaglutide tablets are available under the brand name Rybelsus. They work in the same way but have several advantages over injection pens:

• you only take 1 tablet once daily
• you don't need to use an injection
• they are easy to store - tablets do not need to be kept in cool conditions like the injections do

How does Ozempic work?

Semaglutide, the active ingredient in Ozempic, increases the levels of a hormone called GLP-1. This hormone helps to control blood glucose levels and how much you want to eat.

It works in 3 different ways to lower your blood sugar levels:

1. It helps an organ called the pancreas make more insulin (insulin is the hormone that controls the amount of sugar in your blood) when your blood sugar levels are high.
2. It reduces the amount of sugar that your liver makes and releases.
3. It slows down the rate at which food leaves your stomach, so it takes longer for your body to absorb the sugar from your food.

Semaglutide is a GLP-1 analogue and belongs to the same group as Liraglutide (Saxenda). It increases GLP-1 levels. Doing so causes your stomach to empty and digest food more slowly after eating. This reduces your appetite and leaves you feeling fuller for longer.

Can I buy Ozempic for weight loss?

No. In the UK, Ozempic is only approved for treating type 2 diabetes, not weight loss.

However, as of February 2022, the National Institute for Health and Care Excellence Trusted source National Institute for Health and Care Excellence (NICE) Government Source Go to source (NICE) in the UK has endorsed the use of Semaglutide, under the brand name Wegovy, for obesity treatment. This recommendation means Wegovy is now officially licensed for weight loss, and other Semaglutide medicines should no longer be prescribed off-label for weight loss.

This is why Ozempic is used for type 2 diabetes management.
