Why does my BMI matter?

Orlos is recommended for those with a body mass index (BMI) of 28 or more with other weight-related conditions, such as high blood pressure or type 2 diabetes.

If you have no underlying health conditions related to your weight, Orlos should only be used if you have a BMI of 30 or more.

BMI is a measurement that uses your height and weight to work out if you're currently a healthy weight. For most adults, the ideal BMI ranges from 18.5 to 24.9.

Whilst it's a fairly accurate measurement for most of us, do bear in mind that very muscular people like athletes, weight trainers or heavyweight boxers may receive an inaccurate 'overweight' or 'obese' reading. This is because muscle is much denser than fat.

To calculate your BMI, you need to divide your weight in kilograms by your height in metres squared - or just use our handy calculator and we'll do it for you!

    How does Orlos work?

    The active ingredient in Orlos is a medication called orlistat. Orlistat works by blocking certain chemicals in your gut that digest fat, meaning around a third of the fat you eat won’t be absorbed by your body. The undigested fat will pass through the body naturally - this is why it’s important to follow a low-fat diet whilst taking Orlos, as too much undigested fat can cause unwanted side effects like diarrhoea.

    How long does orlistat take to work?

    Orlistat will get to work reducing the amount of fat absorbed from your food right away.

    However, this doesn’t mean you’ll see weight loss results immediately.

    Weight loss is always a slow process and as much as this treatment can help, how quickly you shed the pounds will ultimately be decided by what you eat and how much exercise you do.

    Does orlistat work without dieting?

    Keeping a close eye on your diet is important whilst taking Orlos. Orlistat works by preventing around a third of the fat you eat from being digested. For orlistat to work properly, you should aim to eat meals with around 15g of fat or less whilst sticking to a lower-calorie diet - following the correct guidance will reduce the likelihood of unwanted side effects and help you to lose more weight than through dieting alone. To find out the exact fat content you should aim for based on your weight, refer to the patient information leaflet.

    Is Orlos suitable for pregnant or breastfeeding women?

    Orlistat, the active ingredient in Orlos, should not be used during pregnancy as it may harm the unborn baby. Orlos is also unsuitable for breastfeeding women as it is unknown whether the medicine can pass into breast milk and cause harm to the baby.

    Does orlistat have any side effects?

    Like all medicines, you may experience side effects while taking Orlos. The active ingredient, orlistat, can commonly cause diarrhoea, wind, or oily discharge when a strict low-fat diet isn’t followed properly. These side effects can be prevented if you follow your low-fat diet exactly as you have been advised. For information on rare side effects, refer to the patient information leaflet.

    Why do I need to answer medical questions before I can buy Orlos?

    You do not need a prescription for Orlos, however, you will be asked to complete a short medical questionnaire by your Chemist4U pharmacist before we can take your order. This includes some simple questions that all pharmacies legally are required to ask before supplying this kind of product. This helps our pharmacy team to be sure that Orlos is the best choice for you.

    Do I still need to request my prescription from my GP?

    Yes, you’ll still need to request your repeat prescription from your GP when you need it.


    You can do this through an app, online, in person, or however else you normally would, so that part of the process won’t change.


    When you’ve requested your medication, your GP will approve it and send your prescription to us electronically so we can fulfil it and get it sent out ASAP. All you need to do is sit back, relax, have a cup of tea, and let us take care of it.
