More information
Xenical (Orlistat 120mg) is a primary pharmacological intervention for obesity management, typically prescribed for patients with a BMI of 30 or above, or those with a BMI of 28+ who have weight-related comorbidities such as hypertension or type 2 diabetes. Unlike appetite suppressants, it works locally in the digestive system to facilitate steady, sustainable weight loss when paired with a calorie-controlled, low-fat diet.

Xenical is a prescription-only weight loss medication designed to treat obesity and overweight adults who have a high Body Mass Index (BMI). It is the branded version of the medication Orlistat and is widely used within the NHS and private healthcare to support patients who have struggled to lose weight through diet and exercise alone. By targeting fat absorption rather than the brain's hunger signals, it provides a unique pathway for weight reduction.
The active ingredient in Xenical is Orlistat, a potent lipase inhibitor that works specifically within the gastrointestinal tract. Each hard capsule contains 120mg of Orlistat, along with inactive excipients such as microcrystalline cellulose, sodium starch glycolate, and povidone. The capsule shell is composed of gelatin and indigo carmine to give it its distinctive turquoise colour.
Many users report that Xenical acts as a "behavioural coach" because the digestive side effects encourage them to stick to a low-fat diet. Clinical data from the XENDOS study shows that patients using Orlistat 120mg achieved significant weight loss over a 12-month period compared to those on a placebo. UK patients often highlight that seeing the physical removal of fat in their stool provides a tangible sense that the medication is working effectively.
The Patient Information Leaflet (PIL) contains essential safety data regarding the use of Xenical and should be read thoroughly before starting treatment. You can access the official electronic medicines compendium (eMC) version or find the physical copy included inside your medication box. It provides details on contraindications, such as chronic malabsorption syndrome or cholestasis.
Xenical works by attaching to gastric and pancreatic lipases, which are the enzymes responsible for breaking down dietary fats into absorbable fatty acids. When these enzymes are blocked, approximately 30% of the fat you consume during a meal remains undigested. This unabsorbed fat then passes through your system and is excreted naturally through bowel movements, effectively reducing your total daily calorie intake.
You should take one 120mg capsule with water at each of your three main meals per day to achieve the best results. The capsule can be taken immediately before, during, or up to one hour after your meal. If you miss a meal, or if you eat a meal that contains no fat, you should skip that dose as the medication only works when fat is present in the digestive tract.
The standard adult dosage is one 120mg capsule taken three times daily. Increasing the dose beyond 120mg three times a day has not been shown to increase weight loss results but does significantly increase the risk of side effects. It is vital to follow the instructions provided by our prescriber and not to exceed the recommended daily limit.
Common side effects of Xenical are primarily digestive and are directly related to the fat-blocking mechanism of the drug. These are often manageable by strictly adhering to a low-fat diet (less than 30% of total calories from fat).
- Oily spotting on underwear or oily discharge.
- Flatulence (wind) with discharge.
- Urgent or increased need to open bowels.
- Fatty or oily stools.
- Abdominal pain or discomfort.
Xenical can interfere with the absorption of fat-soluble vitamins (A, D, E, and K), so it is recommended to take a daily multivitamin at bedtime to ensure nutritional balance. You should inform our prescriber if you are taking medications for epilepsy, thyroid conditions (like Levothyroxine), or blood thinners (like Warfarin), as Orlistat may affect their efficacy. It is not suitable for pregnant or breastfeeding women.
Xenical differs from newer injectable treatments like Wegovy or Mounjaro because it does not affect appetite-regulating hormones. Instead, it blocks fat absorption. While GLP-1 injections often produce higher total weight loss, Xenical is a non-injectable, tablet-based option that has a long-standing safety profile spanning over two decades.
| Treatment | Type | Mechanism | Availability |
|---|---|---|---|
| Xenical (Orlistat) | Capsule | Blocks 30% fat absorption | Prescription (120mg) |
| Alli | Capsule | Blocks 25% fat absorption | Over-the-counter (60mg) |
| Wegovy | Injection | Suppresses appetite (GLP-1) | Prescription |
Does Xenical reduce appetite?
No, Xenical does not suppress your appetite or make you feel full. It only prevents the body from absorbing fat from the food you eat. If you are looking for appetite suppression, you may wish to discuss other options with our clinical team.
How much weight can I lose with Xenical?
Clinical trials show that many patients lose 5% or more of their body weight within the first 12 weeks of treatment. According to NICE guidelines, if you have not lost at least 5% of your body weight after 3 months, you should stop taking the medication.
What should I eat when taking Xenical?
You should follow a nutritionally balanced, calorie-controlled diet where roughly 30% of calories come from fat. Eating high-fat meals (such as fried foods or fatty meats) will significantly increase the likelihood of digestive side effects like oily stools.
Can I take Xenical and Ozempic together?
Combining different weight loss medications is generally not recommended unless specifically advised by a specialist consultant. Using Xenical alongside GLP-1 agonists like Wegovy (the weight loss version of Ozempic) can lead to severe gastrointestinal distress.
