Xenical weight loss pills work by changing the way your body digests and absorbs fat. It can block up to 30% of the dietary fat that is usually absorbed from the food you eat. This helps you lose weight, as the fat is passed on when you go to the bathroom instead of being absorbed into your body.
What does Xenical do to your body?
Xenical tablets belong to a group of medications called “lipase inhibitors”. These medications block an enzyme for digesting fat in your intestines called lipase. This prevents your body from absorbing some of the fat in your food. Instead, the fat is passed out of your body as stool waste.
How long does Xenical take to work?
Xenical can start working as early as 2 days from the start of treatment, but it may take up to 2 weeks for you to start seeing results. You should expect optimal weight loss results within the first 3 months of taking Xenical.
Speak to your doctor if you have not lost at least 5% of your body weight (your weight at the start of treatment), after taking Xenical for 3 months.

Xenical (Orlistat) has been proven through clinical trials to be one of the most safest and effective medicines for treating obesity. It prevents your body from absorbing up to 30% of the dietary fat from your meals, and can help you lose more than 10% of your body weight within 6 months of treatment.
How much weight can you lose on Xenical in a month?
You can expect to lose 2kg-4kg in the first month when you start taking Xenical tablets. These results can vary from person to person, based on factors like starting weight, underlying medical conditions, and how well you keep up with other complementary lifestyle changes such as dieting and exercise.
How long does it take to see results from Xenical?
Xenical starts to work within 1-2 days after first taking it, but you may not see results straight away. Some patients notice visible weight loss after 2 weeks of taking Xenical, though it may take a little longer depending on your body and lifestyle changes. Most patients say they see the best results in the first 3 months of taking Xenical.

Swallow 1 tablet of Xenical after every main meal that contains fat, up to 3 times per day. This is usually at breakfast, lunch, and dinner. You should swallow your capsules whole with water. If you eat a meal that doesn’t contain fat, you don’t need to take Xenical.
Who can use Xenical?
Xenical is recommended for people:
- with a BMI of over 30kg/m2
- with a BMI of over 28kg/m2, and other medical conditions like type 2 diabetes or high blood pressure
- who have tried other weight loss options but have been unsuccessful
Our doctors will take your BMI and all of your medical history into consideration and may prescribe off-label when making a decision about treatment.
When should I take Xenical?
You should take Xenical tablets with every main meal that contains fat, up to 3 times per day.
You can take Xenical immediately before, during or up to 1 hour after a main meal, containing fat. Do not take Xenical if you miss a meal or the meal doesn’t contain fat.
What is the best way to use Xenical?
The best way to use Xenical is alongside complementary lifestyle changes that can help you lose weight. Working with your doctor or another weight loss specialist to create a calorie-controlled diet plan and exercise routine will make Xenical even more effective in helping you lose weight.
How long can you take Xenical for?
You typically take Xenical for 3-6 months, but it can be prescribed for up to a year in some cases. It is thought that there is no time limit on how long you can safely take Xenical for, as long as you are seeing positive results from it. However, you should not continue to take Xenical longer without an assessment with your doctor.
Can you skip a day on Xenical?
You only need to take Xenical after eating a meal that contains fat, so if you go for a day without eating a fatty meal then you could skip a day of Xenical.
If you accidentally skip or miss your Xenical dose, take it as soon as you remember as long as it is within an hour of your last meal, then continue your next dose as usual. If it is outside this time or you miss several doses, speak to your doctor as soon as possible for advice on what to do next.

There is no such thing as a “normal” BMI, though there is a range that is defined as “healthy.” A healthy BMI is between 18.5 and 24.9. You are classed as overweight if your BMI is between 25 and 29.9, and obese if your BMI is above 30.
Xenical is usually only prescribed to those who are obese, or who have a BMI of 30+. In some cases Xenical may be prescribed to those who have a BMI of 28, such as if they have high blood pressure or type 2 diabetes.

Xenical is only available at a dosage of 120mg. This dosage is taken 3 times a day with each meal, for a total dosage of 360mg of Xenical per day.

Xenical is an effective weight loss treatment for a lot of people, but it may not be right for you. Fortunately, there are alternative weight loss medications available to help you.
Orlistat vs Xenical
Xenical tablets are a branded version of Orlistat, which means that they are the same medication and work in the exact same way. The only difference between Xenical and Orlistat is the name on the box, and the price.
Xenical vs Alli
Xenical and Alli are branded versions of Orlistat, which means they both work in the same way. However, Alli is only available at the lower dosage of 60mg, while Xenical is available at 120mg. Because it is a higher dosage, Xenical is more effective for most people than Alli.
Unlike Xenical, Alli is available over the counter, while Xenical requires a prescription before you can get it.

Wegovy is a weight loss injection that works differently to Xenical tablets. While Xenical helps you lose weight by changing how your body absorbs fat, Wegovy works by reducing your appetite. This helps you lose weight by reducing your calorie intake, as you don’t need to eat as much to feel full.
Wegovy might be a good alternative if you do not like swallowing tablets, or if Xenical is not safe for you to take.

Frequently asked questions
How do I know if Xenical is working?
Xenical starts working in 1-2 days, but you might not see results for up to 2 weeks. One of the more obvious signs that Xenical is working is oilier poops than normal, which show that unabsorbed fat is being passed on through your stool.
Does Xenical work on existing fat?
No, Xenical will not reduce or burn existing fat, it reduces the amount of fat your body absorbs from future meals.
Can I take Xenical if I am pregnant or breastfeeding?
No, it is currently not recommended to take Xenical when pregnant or breastfeeding. This is because the medication may pass on to your newborn child through breast milk, or to your unborn baby in the womb.
Does Xenical make you poop?
Yes, Xenical can make you need to poop more urgently or more frequently if you eat a fatty meal. This is because some of the fat you eat will be passed on when you go to the bathroom, so if you eat a very fatty meal, it increases the amount of fat in your poop.
