Navigating Wegovy Alternatives: What You Need to Know
Medically reviewed by
Dr Kathryn BasfordLast reviewed: 19 Feb 2026
Wegovy is an injectable medication that can help you lose and keep off weight. The active ingredient semaglutide works by reducing your appetite, so following a diet and exercise plan is easier. There are also other injectable medications and weight loss pills if Wegovy isn’t suitable for you.
If you want to know more about the best Wegovy alternatives, we explore these in more detail below.
What are Wegovy injections?
Wegovy is a type of prescription weight loss treatment. It can be used if you want to lose weight and have been struggling to do this through diet and exercise alone. To be suitable for Wegovy, you must:
- have a BMI of over 27 and a health condition that is affected by your weight, such as high blood pressure, or
- have a BMI of 30 or above
The active ingredient is semaglutide, which is a GLP-1 agonist. This works by reducing your appetite, which can help you stick to a reduced calorie intake, so you can lose weight safely.
Wegovy is taken once a week and should be injected into your lower abdomen, thigh, or upper arm.
How does a GLP-1 agonist work?
GLP-1 (glucagon-like peptide-1) is a hormone that’s released naturally when you eat. It tells your brain that you’re full and reduces blood sugar levels.
Semaglutide acts in the same way as this hormone, tricking your brain into believing you’re full for longer. This means you don’t feel hungry, making it easier to stick to a diet regime.
Why might you need an alternative to Wegovy?
There are several reasons why you might need an alternative to Wegovy for weight loss, such as:
- it’s not available in your country
- you don’t meet the requirements to take Wegovy (as listed above)
- it’s not suitable due to another medical condition
- it could interact with another medication you currently take
- you don’t want to use an injectable medication
- you’d prefer a Wegovy alternative
- you want to find a cheaper alternative to Wegovy
- you get side effects and want to try a different treatment
Injectable alternatives to Wegovy for weight loss
Mounjaro (Tirzepatide)
Mounjaro is another weight loss injection that contains the active ingredient tirzepatide. It’s a GIP and GLP-1 agonist, which means it mimics 2 hormones that:
- make the pancreas stop releasing insulin after eating
- send signals to the brain that you are full
- slow digestion, to make you feel fuller for longer

Please note: Wegovy 7.2mg has been authorised as of 17th February 2026 and is a maintenance option like 2.4mg. However, the pen with the 7.2mg dosage has not been released yet by the manufacturer and is expected before the end of 2026.
Saxenda (Liraglutide)
Saxenda contains the active ingredient liraglutide, which works in the same way as semaglutide, as it’s a GLP-1 agonist as well. It should be injected once daily, and the recommended dose is 3mg. You will follow a regime to slowly increase the dosage. This allows your body to adjust to the medication and reduces side effects.

Ozempic (Semaglutide)
Ozempic is a type 2 diabetic treatment for managing blood sugar levels. It’s sometimes used as a weight loss treatment, but is only meant to treat diabetes type 2, which often comes along with obesity. Like Wegovy, Ozempic contains semaglutide, a GLP-1 agonist.
The current dose for type 2 diabetes is a maintenance dose of 1mg, which would be gradually increased when starting treatment. It should be taken once a week and is prescription only. Ozempic can only be prescribed off-label for weight loss. At ZAVA we do not prescribe Ozempic off-label.

Victoza (Liraglutide)
Victoza contains the active ingredient liraglutide, like Saxenda. Its primary use is managing blood sugar levels in people with type 2 diabetes, but it can also be an effective weight loss treatment. It’s currently not approved for weight loss, although it may be prescribed off-label.
Victoza should be taken once a day. It’s a GLP-1 agonist, so it can trick your brain into thinking you are full. Please note: We do not prescribe Victoza off-label for weight loss at ZAVA.

What is a natural alternative to Wegovy?
There is no natural alternative medication for Wegovy, but there are natural alternatives to Wegovy for weight loss, such as:
- eating a healthy, balanced diet
- exercising regularly
- joining a local weight loss group
- setting realistic weight loss goals
- slowly reducing your calorie intake and making healthier lifestyle choices
- avoiding fad diets and very low-calorie diets, which aren’t good for your health and aren’t likely to lead to long-term weight loss

You may also be referred by your GP for surgery if medications and natural weight loss treatments do not work.

Deciding which weight loss treatment is best for you depends on your current medical conditions, weight, and preferences. You can also speak through your patient account to one of our doctors about Wegovy and the Wegovy alternatives we offer.
Frequently asked questions
Is there a cheaper alternative to Wegovy?
Yes, Orlistat is cheaper than Wegovy. It comes in the form of a tablet that you take with meals containing fat. It may not be as effective as Wegovy, as it only works when you eat fat. You can also get Saxenda, which is another weight loss injectable.
What are the side effects of Wegovy for weight loss?
Very common Wegovy side effects include:
- headache
- feeling sick
- throwing up
- diarrhoea
- constipation
- stomach pain
- feeling weak or tired
You’ll take Wegovy at a lower dose to start with. That can reduce these side effects and allows your body to get used to the treatment.
Is there a Wegovy generic?
No, there is currently no generic version of Wegovy available.
Which diabetes drug causes weight gain?
Some diabetes drugs may cause weight gain, such as insulin and medications containing sulphonylureas.
