Xenical FAQs

What is Orlistat?

Xenical is a clinically proven weight loss drug available to help people with a body mass index (BMI) over 30. Xenical works by preventing up to 30% of the fat you consume per meal from being absorbed and taken to your body's fat stores. It has been proven effective in clinical trials, where it showed that it was possible for participants to lose between 5% and 10% of their body weight during each cycle of use.

What's the difference between Orlistat and Xenical?

Orlistat is a generic prescription treatment that prevents a third of dietary fat from being absorbed by the body. Xenical is the branded version that acts in the same way. Alli is a similar treatment, but with a lower dosage (60mg) and a lower potency, only preventing the intake of a quarter of dietary fat.

How does Orlistat work?

Xenical tablets contain the active ingredient orlistat. Once in your body, Xenical works to prevent enzymes from breaking down fat so that it can be absorbed by your digestive system and stored. This means that a third of the fat per meal you consume gets blocked and just passes through your system.

How long does Orlistat take to work?

If combined with a healthy diet (preferably with a fat content of around 30% or less) and exercise, Xenical can produce noticeable results within 2 to 3 months. However, if you have lost less than 5% of your starting weight after 12 weeks of treatment, you should consult with your doctor.

How do I get the best results from Orlistat?

The best results come from combining Xenical with a healthy diet (preferably with a fat content of around 30% or less) and exercise. Of course, for long-term results and to maintain a healthy weight, these lifestyle changes should be made permanent.

What should I eat when taking Orlistat?

Even though this treatment is designed to aid weight loss, to maximise effects, and to benefit your health long-term, it is advised to maintain a healthy diet, low in fat. Of course, this should go without saying.

Can I buy Orlistat over the counter?

No. Xenical requires a prescription. However, Alli is an over-the-counter alternative that works in the exact same way. Both treatments contain the active ingredient orlistat, which prevents the digestion of fat. Xenical has a higher potency, though Alli is still effective.

What's the difference between Orlistat and Alli?

Xenical and Alli work in the same way. The active ingredient prevents fat from being digested and allows it to pass straight through your system. The difference between the two lies in their potency. Xenical comes in 120mg pills, and prevents a third of fat from being digested, whereas Alli comes in a 60mg dosage and prevents one-quarter.

How do I take Orlistat?

Xenical is currently only available on prescription, as 120mg tablets. Using the medication is simple, every capsule should be taken with a full glass of water during, or at the latest, one hour after each meal, three times a day. You should still take a pill even if you feel you have had a meal with low-fat content.

Can I buy Orlistat without a prescription?

No, Xenical does require a prescription. Luckily, HealthExpress provides a quick and easy prescription service, as well as speedy delivery that can have your treatment at your front door the very next day.

Is Orlistat safe?

There is a risk factor involved with all treatments, and that is why it's very important to first speak with a medical professional. More common side effects include an increase in bowel movements, flatulence (with an oily discharge) and abdominal pain.

What are the side effects of Orlistat?

The severity of the potential side effects varies from person to person. This means that while some may have to deal with more severe side effects, others won't experience any at all. Xenical tablets can cause issues in your gastrointestinal tract, which can include an increase in bowel movements, flatulence (with an oily discharge) and abdominal pain.

Is Orlistat only available in 120mg?

Orlistat can be purchased as branded Xenical in 120mg pills, designed to prevent approximately a third of fat from being digested. Alternatively, it is available over the counter in a 60mg dosage as Alli. This dosage prevents roughly one quarter of fat intake.

What results can I expect from Orlistat?

Xenical has been tested thoroughly in clinical studies. In one 2011 study, when compared with a placebo, orlistat caused a significant reduction in weight (5.6% against 2.3%), BMI and waist circumference, cholesterol and LDL levels.
