Xenical is a medicine used to treat obesity. It works in your digestive system to block about one-third of the fat in the food you eat from being digested.
Xenical attaches to the enzymes in your digestive system (lipases) and blocks them from breaking down some of the fat you have eaten during your meal. The undigested fat cannot be absorbed and is eliminated by your body.
Xenical is indicated in the treatment of obesity in conjunction with a low calorie intake diet.
2. What you need to know before you take XENICAL
Do not take XENICAL
- if you are allergic (hypersensitive) to orlistat or to any of the other ingredients of Xenical,
- if you have chronic malabsorption syndrome (insufficient absorption of nutrients from alimentary tract),
- if you have cholestasis (liver disorder)
- if you are breast-feeding
Warnings and precautions
Weight loss may also affect the dose of medicines taken for other conditions (e.g. high cholesterol or diabetes). Be sure to discuss these and other medicines you may be taking with your doctor. Losing weight may mean you need adjustments to the dose of these medicines.
To gain the maximum benefit from Xenical you should follow the nutrition program recommended to you by your doctor. As with any weight-control program, over-consumption of fat and calories may reduce any weight loss effect.
This medicine can cause harmless changes in your bowel habits, such as fatty or oily stools, due to the elimination of undigested fat in your faeces. The possibility of this happening may increase if Xenical is taken with a diet high in fat. In addition your daily intake of fat should be distributed evenly over three main meals because if Xenical is taken with a meal very high in fat, the possibility of gastrointestinal effects may increase.
The use of an additional contraceptive method is recommended to prevent possible failure of oral contraception that could occur in case of severe diarrhoea.
The use of orlistat may be associated with renal stones in patients suffering from chronic kidney disease. Inform your doctor whether you suffer from problems with your kidney.
Xenical is not intended to be used in children.
Other medicines and Xenical
Please inform your doctor or pharmacist if you are taking or have recently taken any other medicines, even those not prescribed.
This is important as using more than one medicine at the same time can strengthen or weaken the effects of the medicines.
Xenical may modify the activity of:
- Anticoagulant drugs (e.g. warfarin). Your doctor may need to monitor your blood coagulation.
- Ciclosporin. Co-administration with ciclosporin is not recommended. Your doctor may need to monitor your ciclosporin blood levels more frequently than usual.
- Iodine salts and/or levothyroxine. Cases of hypothyroidism and/or reduced control of hypothyroidism may occur.
- Amiodarone. You may ask your doctor for advice.
- Medicines to treat HIV.
Xenical reduces the absorption of supplements of some fat soluble nutrients, particularly beta-carotene and vitamin E. You should therefore follow your doctor’s advice in taking a well balanced diet rich in fruit and vegetables. Your doctor may suggest you take a multivitamin supplement.
Orlistat may unbalance an anticonvulsivant treatment, by decreasing the absorption of antiepileptic drugs, thus leading to convulsions. Please contact your doctor if you think that the frequency and/or severity of the convulsions have changed when taking Xenical together with antiepileptic drugs.
Xenical is not recommended for people taking acarbose (an anti-diabetic drug used to treat type 2 diabetes mellitus).Xenical with food and drink
Xenical can be taken immediately before, during a meal or up to one hour after a meal. The capsule should be swallowed with water.
Pregnancy and breast-feeding
Taking Xenical during pregnancy is not recommended.
You must not breast-feed your infant during treatment with Xenical as it is not known whether Xenical passes into human milk.
Driving and using machines
Xenical has no known effect on your ability to drive a car or operate machinery.
3. How to take XENICAL
Always take Xenical exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure. The usual dose of Xenical is one 120 mg capsule taken with each of the three main meals per day. It can be taken immediately before, during a meal or up to one hour after a meal. The capsule should be swallowed with water.
Xenical should be taken with a well-balanced, calorie controlled diet that is rich in fruit and vegetables and contains an average of 30 % of the calories from fat. Your daily intake of fat, carbohydrate and protein should be distributed over three meals. This means you will usually take one capsule at breakfast time, one capsule at lunch time and one capsule at dinner time. To gain optimal benefit, avoid the intake of food containing fat between meals, such as biscuits, chocolate and savoury snacks.
Xenical only works in the presence of dietary fat. Therefore, if you miss a main meal or if you have a meal containing no fat, Xenical need not be taken.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed. Otherwise, your doctor may think that it was not effective or well tolerated and may change your treatment unnecessarily.
Your doctor will discontinue the treatment with Xenical after 12 weeks if you have not lost at least 5 % of your body weight as measured at the start of treatment with Xenical.
Xenical has been studied in long-term clinical studies of up to 4 years duration.
If you take more XENICAL than you should
If you take more capsules than you have been told to take, or if someone else accidentally takes your medicine, contact a doctor, pharmacist or hospital as you may need medical attention.If you forget to take XENICAL
If you forget to take your medicine at any time, take it as soon as you remember provided this is within one hour of your last meal, then continue to take it at the usual times. Do not take a double dose. If you have missed several doses, please inform your doctor and follow the advice given to you. Do not change the prescribed dose yourself unless your doctor tells you to.
If you have further questions on the use of this medicine, ask your doctor or pharmacist.
