Ozempic is an anti-diabetic medication designed to treat type 2 diabetes. Secondary clinical studies have also discovered that it can also aid weight loss in those struggling with long-term weight management.
Ozempic is available in the form of an injection and should be taken once a week on the same day each week, unless otherwise instructed by your doctor. The injection can be administered with or without food at any time during the day.
The drug’s primary active ingredient is Semaglutide, which increases insulin secretion to help control blood sugar levels in those with type 2 diabetes. At higher doses, Ozempic can help to suppress appetite and make you feel fuller for longer after a meal, thereby leading to weight loss.
It costs £160/month
Yes. A study of over 2000 overweight and obese patients found that over the 68 week period, those who took a 2.4mg weekly dose of Semaglutide (Ozempic) lost almost 15% of their body weight compared with those who took the placebo who lost just 2.4%.
The most common side effects of Ozempic include:
The drug has also been reported to cause some less common, more serious side effects. Namely:

Saxenda is a form of prescription medication used both in the treatment of type 2 diabetes and in chronic weight management.
Saxenda is an injection that should be administered at the same time every day, unless otherwise instructed by your doctor. The injection can be taken in your stomach, upper leg or upper arm. Detailed instructions can be found on the enclosed patient information leaflet in the product’s packaging.
Saxenda’s active ingredient is the GLP-1 analogue, Liraglutide. It works by helping the pancreas to produce the right amount of insulin when blood glucose levels are elevated. Similarly to Semaglutide, Liraglutide also mimics a hormone produced in the gut, which tells your brain that you’re feeling full. This therefore results in the consumption of fewer calories, and thus aids weight loss.
Saxenda costs £300 per month from week 5 of treatment onwards (based on Click2Pharmacy’s 5 pen discount)
Yes. A study conducted in 2021 found that those using Saxenda lost 5.4% of their body weight within the space of 12 months, a much higher percentage than that of those in the placebo group.
Different medications can affect people in very different ways. A medication that causes no side effects for one person may cause many for another, and vice versa, so it’s important to be aware of any possible side effects of a drug before using it. Some of the most common side effects of Saxenda include:
Saxenda has not been widely tested on those aged 75 and over, so for that reason, it’s advised that those within this age category do not take this medication. The drug is also unsuitable for those with severe heart failure, kidney problems, liver problems or issues related to the gut such as IBS. And of course, Saxenda should not be used by those who are allergic to any of the medicine’s ingredients.
Yes. Saxenda is not available over the counter in the UK, and has to be purchased with a prescription. If you think you could benefit from a course of this medication, either chat to your GP or talk to one of our professionals to arrange a prescription today.
