Ozempic For Weight Loss: Can You Lose Weight on Ozempic?

An Ozempic pen is a self-injectable device. It’s prefilled with medication and can be used to inject multiple doses of Ozempic. Ozempic pens are prescription-only treatments for type 2 diabetes.

Ozempic is not a medication licensed for losing weight in people without diabetes, but it is used by diabetes patients. In the UK there are medications that have been specifically developed for weight loss, like Wegovy. Anyone who might benefit from medications for losing weight would be better off using these alternatives.

Ozempic for diabetes

For diabetes, Ozempic stops your blood sugar from spiking. The semaglutide in Ozempic works the same way as the natural hormones your body releases after you’ve eaten to control your blood sugar levels.

Ozempic for weight loss

For weight loss, the semaglutide in Ozempic can also make you more full from less food. It slows down how fast food travels through your body, making you feel fuller for longer. As you're less hungry, it’s easier to stick to a diet without overeating, helping you lose weight. Since Ozempic is licensed for diabetes treatment and can only be prescribed off-licence for weight loss, a better choice might be Wegovy. Wegovy has the same active ingredient and is licensed for weight loss.

Ozempic is only licensed in the UK for managing weight for people who have type 2 diabetes. This means that unless you have type 2 diabetes, it can only be prescribed off-licence for weight loss in the UK. If you want to lose weight but don’t have type 2 diabetes, there are other weight loss treatment options available, like Wegovy, Saxenda, Orlistat or Xenical.

If your doctor agrees to give you a prescription for Ozempic, either on- or off-licence, you can get it filled at most pharmacies. Some online services may also let you order Ozempic online.

Prices for Ozempic will be different depending on how it’s prescribed to you. It’s available on the NHS for people with type 2 diabetes, so it can cost as little as the standard NHS prescription cost, or it can be free if you don’t pay for your prescriptions. But, if it’s offered as an off-licence private prescription, you’ll need to pay full price.

Can you buy Ozempic over-the-counter?

No, Ozempic is a prescription-only medication. This means that it needs to be prescribed by a doctor before you can get it from a pharmacy. Over-the-counter medication can be bought from a pharmacy without seeing a doctor first.

Ozempic is prescription-only because a doctor needs to check if treatment will be safe and effective for you.

What is the generic for Ozempic for weight loss?

There is currently no generic Ozempic available. Generic medications cost less than branded ones like Ozempic, but they’re only available once a patent for a branded medication has run out. The earliest an Ozempic generic will be available in the UK is probably December 5th 2031.

Even when a generic version of Ozempic becomes available, it may still only be licensed for treating diabetes and not for weight loss.

The semaglutide in Ozempic can support weight loss by making you feel fuller after you eat. This reduces your appetite and makes it easier to stick to your diet and avoid overeating or snacking as often. However, since Wegovy also contains semaglutide, has the same effect on appetite and is licensed for weight loss, it can be a better weight loss treatment option.

How quickly does Ozempic work for weight loss?

• Around 2 to 3 weeks after starting treatment. You should start feeling fuller after your first 2 to 3 doses.
• Different people react differently to Ozempic, but you should definitely notice a difference by 6 weeks at the latest if Ozempic works for you.

Although you should start feeling fuller within a number of weeks, it can still take some time to notice a difference in your weight. A major study showing weight loss on Ozempic lasted 68 weeks, so it’s a good idea to expect at least 5% weight loss after just over a year of treatment.

Depending on what you’re using Ozempic for, if you don’t notice any difference after 6 or 8 weeks you can discuss whether to continue or whether to switch to another treatment with your doctor.

“Ozempic can be safe for people without diabetes, but it is only licensed for people with diabetes in the UK. It can be prescribed off-label for weight loss if a doctor approves it. Wegovy, on the other hand, is a medication with the same active ingredient for treating weight loss in people with or without diabetes. We don’t offer Ozempic prescriptions through ZAVA.” – Dr Babak Ashrafi, Clinical Lead for Service Expansion.

The evidence for Ozempic shows that it can reduce blood sugar levels by around 22% and it can reduce the blood sugar spike people experience after eating by 36%.

How much weight can you lose on Ozempic pens?

Studies have shown that Ozempic can be an effective treatment for weight loss that works for around 45% of people who use it, with 17% of users losing more than 10% of their starting weight.

In a 30-week study of Ozempic’s active ingredient semaglutide, at the maintenance dose for Ozempic (1mg):

• 45% lost at least 5% weight
• 17% lost at least 10% weight

What are the Ozempic reviews like?

• 5.6 out of 10 for diabetes on drugs.com
• 3.5 out of 10 for weight loss on drugs.com
• 3.7 out of 5 stars for all treatments on wedmd.com

You should take your Ozempic once a week on the same day of the week if possible. You can use it any time of day, no matter when you’ve eaten.

Always use Ozempic as your doctor has advised you to. Also check the information leaflet that comes with your medication. For more in-depth advice on using your Ozempic see this patient information leaflet.

What happens when you start taking Ozempic?

Some people notice an effect right away, for others it may take a few doses before they see a reduction in their appetite. You should also notice a reduction in your blood sugar after the first week, if you’re diabetic. It can take 8 weeks to see the full effect of Ozempic.

You may also notice some mild side effects when you first start taking Ozempic, as well as when you increase your dose. This can include stomach-related effects like nausea, diarrhoea, vomiting or constipation. These usually go away as your body adjusts to Ozempic.

What happens if you take too much Ozempic?

If you realise you’ve taken too much of your Ozempic, talk to a doctor as soon as possible. You might get side effects like feeling sick. You may also be at risk of rare and more serious side effects. Always take the dose you’ve been prescribed and don’t change your dose without discussing it with a doctor first.

How long can you take Ozempic for weight loss?

Ozempic is safe to use long-term for diabetes. It has not been licensed for weight loss alone so there is no official advice about how long to use it for this purpose. Your doctor will let you know when you’re ready to come off your medication. Don’t stop using your medication without talking to your doctor, unless you have serious side effects. If you’re not sure whether you still need Ozempic, your doctor will be able to advise you.

Can you take Ozempic permanently?

Ozempic can be used as a long-term treatment for type 2 diabetes. It doesn’t have to be permanent though. If lifestyle changes are able to bring weight and blood sugar levels under control, Ozempic treatment can be discontinued.

What foods should be avoided in the Ozempic diet?

No foods will react badly with Ozempic, so nothing is off the table. But, a bad diet can make some of the side effects of Ozempic more likely. Also, a good diet is an important part of managing weight and blood sugar. So, we recommend:

• avoiding high sugar foods, even ones that are sold as healthy, like breakfast bars
• avoid sugary drinks
• avoid high fat foods as well
• avoid foods that are calorie-dense, like big portions of carbohydrates and red meats

Is it safe to mix Ozempic and alcohol?

Alcohol doesn’t react with Ozempic, but they can both lower your blood sugar so watch out for dizziness if you do drink on your treatment.

Excessive drinking can increase your risk of complications from diabetes so it’s a good idea to limit drinking anyway. Also, alcohol has a lot of calories and often leads to overeating so there are a lot of benefits to cutting down on alcohol when taking treatments like Ozempic.

There are 4 doses of Ozempic used for treating diabetes. You start on the lowest dose and then move up to higher doses during the start of your treatment.

How many doses are in an Ozempic pen?

Each pen is only meant to deliver 3 doses. As your dosage increases from 0.25mg, to 0.5mg, and to 1mg, the amount of medication in each pen also goes up.

Ozempic vs other medications

Here are some other medications that are also used for weight loss or diabetes:

Ozempic for weight loss:

• Mounjaro is a weight loss injection that contains tirzepatide, and works similarly to Ozempic. It is the most effective weight loss injection currently available.
• Wegovy is another semaglutide injection medication which is approved for treating weight loss in people who don’t have diabetes as well.
• Saxenda is another similar medication for reducing appetite that uses a similar but slightly different ingredient called liraglutide.

Ozempic for Diabetes:

• Rybelsus is a tablet form of semaglutide which works in a similar way to the injections, but like Ozempic it’s only for people with diabetes.
• Metformin tablets are another kind of diabetes treatment that works by lowering your blood sugar levels.
• Trulicity is similar to Metformin but comes as an injection instead of a tablet.
• Insulin is the hormone your body makes to manage blood sugar itself, but it’s also available as a diabetic medication as well.

If you’re looking to lose weight with medications similar to Ozempic and you don’t have diabetes, you could consider Wegovy or Saxenda.

Other weight loss medications that work slightly differently to Ozempic include branded Xenical and generic Orlistat.

For some people, managing weight loss and controlling blood sugar can be done without medication. Instead, it can be done through:

• diet
• exercise
• weight loss programmes

Even if you are using medication, lifestyle changes like the ones listed above can help improve the effectiveness of your weight loss and blood sugar treatment.

Since Saxenda is licensed for weight loss treatment, it is the better choice for people who only need weight loss treatment. Ozempic is licensed for type 2 diabetes treatment so it may be the better choice if you need help managing your blood sugar levels.

People on Saxenda have a:

• 56% chance of losing at least 5% weight
• 26% chance of losing at least 10% weight
• 12% chance of losing at least 15% weight

Since Saxenda is currently long-term out of stock, a better choice might be Wegovy, since it has the same active ingredient as Ozempic but is designed for weight loss and unlike Saxenda, stock is available.

Yes. Although they have the same active ingredient, they are licensed for different conditions and there are different doses for each.

Ozempic is licensed for treating type 2 diabetes and is available in 0.25mg, 0.5mg and 1mg doses. On the other hand, Wegovy is licensed for weight loss and is available in 0.25mg, 0.5mg, 1mg, 1.7mg and 2.4mg doses.
