How long do Wegovy weight loss injections take to work?

Wegovy injections get to work in your system right away, but that doesn’t mean that the pounds will fall off within a couple of days.

Clinical trials of Wegovy have shown that patients typically lose 15% of their starting body weight during their treatment, but how quickly this happens depends on the number of calories you’re eating every day.

Wegovy works by helping to control your appetite and reduce food cravings, making it easier for you to stick to the low-calorie diet you’ll need to lose weight.

A healthy rate of weight loss is generally considered to be 1 - 2lbs a week, so you may want to use this as a rule of thumb when considering your weight loss goals.

Is Wegovy the same thing as Ozempic?

Wegovy and Ozempic are two medications which use the same active ingredient for different purposes.

They are both manufactured by Novo Nordisk, which holds the patent for both medications at the moment. Ozempic is a medication for patients with type 2 diabetes that helps you to control your blood sugar, and it can be used alone or alongside other medicines like insulin or metformin.

As they both contain semaglutide, these medications work similarly, but that doesn’t mean you can use them interchangeably.

Ozempic is used in different dose sizes to Wegovy, with Wegovy often being prescribed in higher amounts, so if you’re already taking Ozempic for type 2 diabetes you won’t be able to take Wegovy as well, as this could cause an overdose of the active ingredient.

What is Mounjaro?

Mounjaro is a prescription medication that you inject yourself. It’s used for diabetes and weight loss.

Alongside an active and reduced-calorie diet, Mounjaro helps you to lose weight by suppressing your appetite. It allows you to feel fuller for longer and reduces your food cravings.

Is Mounjaro safe for weight loss?

Mounjaro is a safe and effective way to lose weight if you’re obese. It has been approved for weight loss by the MHRA. However, Mounjaro does have side effects that you should be aware of.

Is Mounjaro better than Wegovy?

Mounjaro is more effective than Wegovy when it comes to weight loss results. Research has concluded that people who use Mounjaro lose more weight than those who use Wegovy.

Mounjaro and Wegovy both work in a similar way, however, they are not the same. What works for one person might not be suitable for you.

What is the difference between Wegovy and Saxenda?

Saxenda is another brand of weight loss injection that is very similar to Wegovy.

They work in a similar way, but use different active ingredients and have different dosage sizes. Saxenda uses an active ingredient called liraglutide, which is part of the same group of medicines as semaglutide — GLP-1 receptor agonists.

Saxenda needs to be injected once a day, whereas Wegovy only needs to be injected once a week.

Saxenda pens also need you to set your dose manually and insert a new needle for each dose, Wegovy doesn’t need you to do either of these as each pen is only used once.

The final big difference is that Wegovy has been shown to be much more effective than Saxenda in clinical trials.

With Saxenda you can lose 5% of your starting weight within 12 weeks of taking its maximum dose, but clinical trials of Wegovy have found that patients lose an average of 15% of their starting weight.

Can I drink alcohol while I’m taking Wegovy?

You can drink alcohol while you’re taking Wegovy, it shouldn’t affect the way this treatment works.

However, we always recommend that you drink in moderation and try to drink water or another soft drink between alcoholic drinks to help you stay hydrated.

Something else you should look out for is the calorie content in alcoholic drinks.

Alcoholic drinks often contain a lot more calories than you might expect, so drinking a lot can interfere with your weight loss simply by increasing your calorie intake.

Do Wegovy pens need replacement needles?

Unlike Saxenda, Wegovy pens don’t need you to replace their needles after each use.

This is because Wegovy pens are single-use only, so you won’t need to measure out a dose manually and won’t need to worry about putting a new needle onto your pen.

This is one of the reasons that patients prefer this treatment to Saxenda, as you don’t need to manage dosing or needles by yourself, making the whole process simpler.

Is a sharps bin included with this product?

Yes, we can supply sharps bins you can use to safely dispose of Wegovy or Saxenda pens.

When you have completed your consultation with our prescribers, the option to include a sharps bin with your order will be there for you to select.

Depending on your order size, we may be able to give you your sharps bin for free, but there may be a charge for smaller orders.

Once you have your sharps bin, you will need to contact your local council to organise collection and its safe disposal when your bin is full.
