Wegovy alternatives for weight loss treatment

Alternative weight loss injections to Wegovy

Wegovy isn’t the only weight loss injection available. There are currently 2 approved and regulated injectable Wegovy alternatives, which are:

Mounjaro (tirzepatide)

Mounjaro is a prescription injectable medication approved in the UK for both weight loss and treating type 2 diabetes. The active ingredient is tirzepatide, a GIP and GLP-1 agonist. This means it mimics 2 hormones (GIP and GLP-1), which:

  • stimulates insulin release from the pancreas after eating (for blood sugar regulation)
  • send signals to the brain that you are full
  • slows digestion, to make you feel fuller for longer

Is Wegovy or Mounjaro better for weight loss?

Recent studies have shown that Mounjaro may help more people to lose weight, as the percentage of people that lost 5% or more of their weight on Wegovy was 90.7% on the 7.2mg dose at 72 weeks compared to Mounjaro which was 96.3% on the 15mg dose after 72 weeks. Mounjaro also leads to a slightly higher average weight loss of 22.5% after 72 weeks on the highest dose, compared to 21% for Wegovy.

Both are taken weekly and are a similar price, so it’s up to you which you’d prefer to try. You can also switch from Wegovy to Mounjaro as long as you speak to your doctor before doing so to check the right dose for you to start with.

For a more detailed comparison of these two medications, you can find more information on our dedicated Wegovy vs Mounjaro page.

Liraglutide (Nevolat)

Generic liraglutide, Nevolat 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 maintenance 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.

*percentage initial body weight lost by patients on average according to clinical studies

Is Wegovy or liraglutide better for weight loss?

For most people, Wegovy may be a better option for weight loss than liraglutide. This is because Wegovy only needs to be injected once per week, instead of every day like liraglutide. Wegovy also has a higher percentage of weight loss in clinical trials (as shown in the comparison table), although they were tested over a different number of weeks.

Other diabetes GLP-1 medications

There’s also a few diabetes injections that contain a GLP-1 receptor agonist but are prescribed for managing blood sugar levels. For example, you may have heard of Ozempic

Please note – Ozempic is not recommended for weight loss, although people with diabetes taking it may notice reduced appetite and weight loss as a side effect. Some services may offer these medications as an off-label weight loss treatment, but ZAVA Online Doctor does not offer this. As some services are classing these medications as weight loss injections, we’ll also discuss them here so you can have a clearer picture of what they are.

Ozempic (semaglutide)

Ozempic which is a type 2 diabetic treatment for managing blood sugar levels. Like Wegovy, Ozempic contains semaglutide, a GLP-1 agonist, so a side effect is reduced appetite and weight loss. The current dose for type 2 diabetes is a maintenance dose of maximum 2mg, which is reached after gradually increasing dosage from the starting dose of 0.25mg. This is a much lower dose than the maintenance dose of Wegovy, which is 7.2mg, so is likely to be less effective for weight loss. 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.

Is Wegovy or Ozempic better for weight loss?

Wegovy is a better option than Ozempic for weight loss. They use the same active ingredient, but Wegovy has been manufactured specifically to help people lose weight. It is available at a higher dosage than Ozempic, and it’s more suitable to help people lose weight.

You can find more information about how these two medications compare on our dedicated Wegovy vs Ozempic page.

Which weight loss pill is a good alternative to Wegovy?

If you would rather take a weight loss pill, there are some Wegovy alternatives that work in the same way and some that work differently. These include:

Wegovy pills vs injections

Wegovy pills contain the same active ingredient as the injections, semaglutide. Both treatments are both licensed for weight loss in the UK. The main difference is how they are taken. Wegovy pills are taken once daily, not weekly. They have to be taken with a small amount of water on an empty stomach, after 8 hours of no eating. You then need to wait 30 minutes before eating or drinking anything else. The dosage of the Wegovy pill is also different due to how the treatment is absorbed in the digestive system.

Are Wegovy pills or injections better for weight loss?

Wegovy injections are slightly more effective, leading to an average weight loss of 21% after 72 weeks on the highest dose compared to 17% for Wegovy pills after 64 weeks on the highest dose.

While injections are more effective, pills may be more convenient or suitable for some people who don’t feel comfortable self-injecting.

Wegovy vs orlistat (brand names alli, Xenical, and Orlos)

Orlistat (Xenical, Orlos, and alli) is a prescription weight loss pill that can prevent the digestion and absorption of fat. alli can be bought without a prescription but a pharmacist or doctor still needs to check it’s safe. When taken with a meal, orlistat stops around a third of the fat being absorbed, aiding with weight loss.

Wegovy Orlistat
Active ingredient Semaglutide Orlistat
Highest dosage 7.2mg 120 mg (1 tablet) or 60mg (1 tablet if you’re taking alli or Orlos)

Is Wegovy or orlistat better for weight loss?

Wegovy can help patients lose more weight than those on orlistat according to clinical studies. However, orlistat may be another option for patients who would rather take a tablet than an injection. They also work in different ways, so orlistat could be a good option for those who cannot take GLP-1 agonists. You can also get alli without a prescription, if you want to try a lower dose, over-the-counter weight loss tablet first.

Mysimba (naltrexone and bupropion hydrochloride)

Mysimba is a weight loss pill that also reduces appetite, like Wegovy. It contains 2 active ingredients – naltrexone and bupropion hydrochloride, which are thought to affect the parts of the brain responsible for hunger and energy levels, reducing appetite and cravings. You’ll take 2 pills, twice a day after following a dosage schedule to reach this dose.

*percentage initial body weight loss according to clinical studies

Is Wegovy or Mysimba better for weight loss?

Wegovy and Mysimba have both been proven to be effective for weight loss in clinical trials, but people lost more weight with Wegovy. Mysimba may be a better choice if you can’t take GLP-1 agonists or you don’t want to take an injection. Wegovy may be preferred if you’d rather take a once-weekly injection rather than remember to take 4 pills each day.

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:

  • 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

What is a natural alternative to Wegovy?

There is no natural alternative medication for Wegovy, but there are natural alternatives 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
  • asking family and friends for help
  • getting psychological support

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

Conclusion

Wegovy is a highly effective weight loss medication that works for most people who try it. The most popular alternative is Mounjaro, which works similarly and has been proven to have slightly higher weight loss results, although both can cause significant weight loss. You can switch to Mounjaro if you want to improve your weight loss results, however, due to the price difference, this may not be possible for everyone.

If you’re not losing weight on Wegovy right now, there may be some changes you can make to kickstart your weight loss again, including making sure you’re eating the right foods.

If you find injections uncomfortable, there are a number of tablets for weight loss that can help, such as the Wegovy pill, Mysimba and orlistat. While these medications are less effective than injections, they are still effective and may better suit your needs.

Frequently asked questions

Is there a cheaper alternative to Wegovy?

Yes, orlistat is a cheaper alternative to 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.

Mysimba is also cheaper, which is a weight loss tablet that suppresses appetite, like Wegovy. Results with Mysimba aren’t as high as Wegovy, but it’s still an effective treatment.

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. This can help reduce side effects and allows your body to get used to the treatment. We’ve also created a guide on Wegovy side effects if you want to know more about them.

Is there a Wegovy generic version?

No, there is currently no generic version of Wegovy available. The medication is still under patent, so there won’t be a generic Wegovy available until this patent has run out.

Which diabetes drug causes weight gain?

Some diabetes drugs may cause weight gain, such as insulin and medications containing sulphonylureas.

Can you buy Wegovy online?

Yes, you can buy Wegovy online, from trusted and regulated sellers, such as ZAVA. Simply complete our online questionnaire, which will be reviewed by one of our doctors. If Wegovy is suitable for you, we’ll prescribe it and send it to your home, with free delivery.
