Take one capsule three times daily with your main meals.

If there is no fat in one of your meals, or if you miss a meal, there is no need for you to take a dose of orlistat.

Orlistat is a medicine that can help you to lose weight if you are obese or overweight. It works by interfering with the way fat is digested and absorbed by your body. It prevents the action of enzymes found in the digestive juices of your stomach and small intestine. These enzymes normally break down the fat which you consume in your diet, allowing it to be absorbed into your bloodstream. By blocking the enzymes' action, orlistat reduces the digestion of fat. This allows the fat you have eaten to be passed out of your body instead of being absorbed by your body, and this helps you to lose weight.

Orlistat only prevents about a third of the fat you eat from being absorbed so it is also important for you to eat a lower-fat weight-reducing diet, and to exercise regularly.

Orlistat is available on prescription, and lower-strength capsules (Alli® brand) can also be bought from pharmacies. It is not suitable for everyone and a number of guidelines apply as to who can be supplied with orlistat - more information about this can be found in the separate health information leaflet called Orlistat Weight Loss Medicine.

Before taking orlistat

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking orlistat it is important that your doctor or pharmacist knows:

  • إذا كنتِ حاملاً، تحاولين الإنجاب أو تقومين بالرضاعة الطبيعية.

  • إذا كان لديك أي مشاكل في طريقة عمل الكلى لديك.

  • If you have a condition called chronic malabsorption syndrome, where your food is not absorbed properly.

  • If you have a problem with the flow of bile to your liver, a condition called cholestasis.

  • إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

  • إذا كنت تتناول أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.

How to take orlistat

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about orlistat and will provide you with a full list of the side-effects which you may experience from taking it.

  • Take orlistat exactly as your doctor or pharmacist tells you to. There are two strengths of capsules - 60 mg and 120 mg. The lower-strength capsule is available from pharmacies whilst the higher-strength capsule is only available on a prescription from a doctor.

  • The usual dose of orlistat is one capsule (60 mg or 120 mg) taken with each of your three main meals of the day. Swallow the capsule with a drink of water as you are about to eat the meal or soon afterwards. It can be taken up to one hour after a meal. Do not take more than three doses a day.

  • Orlistat only works when there are fats in what you eat, so if you miss a meal or if you eat a meal which is fat-free then do not take a dose of orlistat.

  • If you forget to take a dose, do not worry; just take a capsule with your next meal as usual. Do not take two doses together to make up for a forgotten dose.

تحقيق أقصى استفادة من علاجك

  • Orlistat is only suitable if your body mass index (BMI) is 28 kg/m2 or greater. BMI is calculated by dividing your weight in kilograms by the square of your height in metres. So, for example, if you weigh 85 kg and are 1.7 metres tall, your BMI is 85/(1.7 x 1.7), which is 29. Alternatively, your practice nurse can measure and weigh you, and tell you your BMI.

  • To lose weight, the best chance of long-term success is to eat a well-balanced, calorie-controlled diet that is low in fat and rich in fruit and vegetables. If you are able, you should also exercise regularly. See the separate health information leaflet called Weight Loss (Weight Reduction) for more details. Your practice nurse will be able to give you further help and advice about eating a healthy diet and taking suitable exercise.

  • If you have bought orlistat from a pharmacy, check your weight regularly and, if you have not lost weight after three months, see your doctor or pharmacist for further advice. You must lose at least 5% of your weight within three months from starting orlistat; if not, the treatment should be stopped. Do not continue taking orlistat for longer than six months without seeing a doctor.

  • If you have been prescribed orlistat, your doctor will want to review your weight and treatment regularly to decide if it is still appropriate for you to carry on taking orlistat. You must lose at least 5% of your weight within three months from starting orlistat; if not, the treatment is likely to be stopped. It may also be necessary for you to have some blood tests during treatment to check your blood lipids. If you continue to lose weight after six months, your doctor may advise that you continue to take orlistat for up to a year, or possibly longer.

  • The fat which remains undigested from your diet can cause changes in your bowel habit, resulting in wind, loose stools, and oily spotting from your back passage. Reducing the amount of fat you eat in your meals will reduce the likelihood of these harmless, but unpleasant, side-effects.

  • Orlistat can interfere with the absorption of various medicines, including possibly the contraceptive pill. If you take 'the pill' and you have severe diarrhoea as a side-effect of taking orlistat, it could reduce the effectiveness of the contraception. If you experience diarrhoea, use another method of contraception in addition to the pill - for example, a condom.

  • Orlistat can also interfere with the absorption of vitamins which are fat-soluble. These are vitamins A, D, E and K. If you decide to take a multivitamin supplement, take it at a time when you are not also taking orlistat. The best time to take the supplement would be at bedtime.

  • If you have diabetes, it is important that you speak with a doctor before you start taking orlistat, as it can affect the control of your diabetes. This may require extra monitoring.

  • After you stop taking orlistat, you may put some weight back on. Remembering to continue with your healthy eating and increased level of physical activity can help to prevent this.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with orlistat.

الأسئلة الشائعة

Can orlistat be used by anyone who wants to lose weight?

No, orlistat is not suitable for everyone. There are specific guidelines for its use, including a requirement for your body mass index (BMI) to be 28 kg/m2 or greater. If you are considering using orlistat, it's important to consult a doctor or pharmacist to determine if it is appropriate for you.

What is the difference between the prescription and pharmacy versions of orlistat?

Orlistat is available in two strengths: 60 mg and 120 mg capsules. The lower-strength 60 mg capsules (branded as Alli® or Orlos®) can be bought directly from pharmacies, while the higher-strength 120 mg capsules (branded as Xenical®) require a prescription from a doctor. Both strengths work the same way but differ in their availability and dosage.

How long can I continue to take orlistat?

If you bought orlistat from a pharmacy, you should not continue taking it for longer than six months without seeing a doctor. If you have been prescribed orlistat, your doctor will review your progress regularly. If you continue to lose weight after six months, your doctor may advise you to continue taking it for up to a year, or potentially longer, depending on your individual circumstances.

What should I do if I experience severe diarrhoea while taking orlistat and I am on the contraceptive pill?

If you are taking the contraceptive pill and experience severe diarrhoea as a side effect of orlistat, it could reduce the effectiveness of your contraception. In this situation, it is important to use an additional method of contraception, such as a condom, to ensure you remain protected.

Should I take a vitamin supplement while using orlistat?

Orlistat can interfere with the absorption of fat-soluble vitamins (A, D, E, and K). If you choose to take a multivitamin supplement, it's best to take it at a different time from your orlistat dose to ensure maximum absorption. The article suggests taking the supplement at bedtime.
