Xenical is a safe and clinically proven weight loss drug used to treat people who are overweight or with a body mass index (BMI) of more than 30kg. They are designed to be used alongside a low-calorie diet.
Xenical 120mg works by blocking fat from your digestive system. It stops around one-third of fat from being absorbed by attaching to enzymes in your digestive system, which is then eliminated by your body.
To get the best results from xenical it’s important to monitor what you eat. This weight loss pill only works when fat is present in your diet, and it shouldn’t be taken if you miss a main meal or if you have a meal containing no fat.
It’s important to follow a balanced, calorie-controlled diet with an average of 30 % of the calories from fat. Sources of carbohydrates, protein and fat should be distributed across your three meals for the day, and you should avoid snacking on fatty foods in between meals.
If you have not lost at least 5 % of your body weight after 12 weeks your treatment may be stopped.
Drinking alcohol during your weight loss programme can be counterproductive because alcohol is high in calories. This interferes with your weight loss goals and irritates the digestive system, worsening some of the side effects associated with xenical. Heavy drinking can also interrupt nutrient absorption and contribute to vitamin deficiencies.
Both medicines work in a similar way. The difference between orlistat and xenical is that xenical is a branded medication, while orlistat tablets are the generic version, meaning it is marketed under its chemical name rather than a brand name.
Xenical (Orlistat):
Ozempic (Semaglutide):
Active ingredient: Orlistat
Inactive ingredients: microcrystalline cellulose (E460), sodium starch glycolate (type A), povidone (E1201), sodium laurilsulfate and talc. The capsule shell consists of gelatine, indigo carmine (E132), titanium dioxide (E171) and edible printing ink.
Take one 120 mg capsule three times a day, swallow with water. This should be taken before, during or an hour after breakfast, lunch and dinner.
If you forget to take your medicine, do not take a double dose. Instead, take it as soon as you remember, but only if this is within one hour of your last meal. After this, continue to take it at the usual times. Speak to your GP or pharmacist if you have missed several doses.
You should contact your doctor or pharmacist urgently if you take more capsules than you have been told to take.
Most symptoms are typically mild; however, you should inform your doctor or pharmacist if you feel unwell whilst using xenical.
Very common side effects (more than 1 in 10 affected):
Common side effects (more 1 to 10 users in 100 affected):
Stop taking Xenical and tell your doctor if you experience symptoms of an allergic reaction. This includes:
There are certain circumstances when you should not take xenical. Do not take this medicine if:
You may need to adjust the dose of any medicines you are taking as you lose weight. It is important to let your doctor or pharmacist know of any other medications you are taking before you start using xenical.
A diet high in fat can increase your likelihood of gastrointestinal effects and a change in bowel movements. This may cause you to have fatty or oily stools because of the elimination of undigested fat in your faeces. It is important to spread fat intake across your three main meals per day. Over consumption of both calories and fat whilst using xenical will also reduce its effect and potentially how much weight you lose. Effort must be made to stick to your nutrition programme throughout the course of your treatment.
Some people can experience severe diarrhoea which could impact the way oral contraception works therefore an additional contraceptive method is recommended whilst using xenical.
You should also inform your doctor whether you suffer from problems with your kidney. Orlistat, the main active ingredient in xenical, has been linked with renal stones in people suffering from chronic kidney disease.
Let your doctor or pharmacist know if you are taking or have recently taken any other medicines, including non-prescription drugs. Using multiple medicines at the same time can strengthen or weaken the effects of the medicines.
Xenical can impact the way the following medicines work:
It may also decrease the absorption of antiepileptic drugs leading to convulsions. Tell your doctor if you notice that the frequency and/or severity of the convulsions have changed when taking xenical together with antiepileptic drugs.
The absorption of supplements with some fat-soluble nutrients, particularly beta-carotene and vitamin E can be reduced when using this medicine. It’s important to maintain a well-balanced diet rich in fruit and vegetables. In some cases, your doctor or pharmacist may suggest you take a multivitamin supplement.
Xenical is not recommended for people taking acarbose, an anti-diabetic drug used to treat type 2 diabetes mellitus.
Taking xenical whilst pregnant is not recommended. Weight loss during pregnancy is not typically advised because of the potential harm to both mother and the developing fetus. The nutritional needs of the mother increase during this time and xenical can interfere with the absorption of fat soluble vitamins. Restricting calories or using weight-loss medications could affect the development of the baby.
You must not breastfeed during treatment with xenical because there is little evidence as to whether xenical passes into human milk.
This is entirely dependent on your weight loss goals, health and preferences. We sell a range of clinically proven prescription and non-prescription weight loss pills which are designed to be used alongside a weight loss programme. Weight loss takes patience and requires realistic expectations for you to achieve success.
Xenical has been studied in long-term clinical studies of up to 4 years. Clinical trials have found xenical to be effective in helping people who are overweight lose about 5-10% of their body weight over a period of 6 to 12 months, when used alongside a low-calorie diet. Orlistat has been proved to be safe and effective for use on the NHS.
