Frequently Asked Questions

Are Mysimba and Wellbutrin the same thing?

Wellbutrin is an antidepressant medication used in the UK to treat nicotine addiction and help you quit smoking.

It’s also used to treat major depressive disorder (MDD) and seasonal affective disorder (SAD) in other countries, although it is not currently licensed to be used for this in the UK.

The active ingredient in Wellbutrin is Bupropion, which is also used as an active ingredient in Mysimba, making these medicines very similar.

However, as Mysimba also contains a second active ingredient (Naltrexone) which is not included in Wellbutrin, these medications are not the same thing.

With that in mind, Wellbutrin should not be used for weight loss and should only be used as prescribed by a doctor to help you quit smoking.

Are Mysimba weight loss tablets right for me?

Mysimba tablets should only be taken by adults over the age of 18 who have a body mass index (BMI) of 30 and above, which would place them into the obese category.

However, you may also be able to take this treatment if your BMI is between 27 and 30 and you also have weight-related conditions, such as high blood pressure, type 2 diabetes, or high levels of fat in your blood.

Your BMI is calculated using your weight and your height and is a good indicator of whether or not you are at a healthy weight.

If you’re unsure what your BMI is, we’d recommend using the NHS’s BMI Calculator which will work it out for you and give you an indication of whether you may be able to use Mysimba for weight loss.

Do I need a prescription for this medication?

You do need a prescription for this medication in the UK.

Our healthcare professionals can provide prescriptions if they think this treatment would be right for you and your condition.

When you click the button which reads “Start Consultation” at the top of this page, you’ll see a short questionnaire set up by our healthcare team which is designed to help them understand your medical needs.

Just like an in-person consultation with your GP, our doctors will assess your answers to their questions and write a prescription for the treatment they think will be best for you.

You’ll then be able to pay for your medication and we’ll send it out to you quickly and in discreet packaging.
