What is Xenical

For some people, losing weight through dietary changes and exercise alone is a continual struggle. Obesity is a growing problem in the UK and in many other parts of the world, and it is a crippling disease that can affect every aspect of our lives. The health concerns and the poor self-image associated with it make weight loss and weight control two of the primary goals in achieving a long and healthy life. This has led to the development of prescription weight loss treatments like Xenical.

These tablets contain the lipase inhibitor orlistat, and they work by reducing the amount of fat that the body absorbs during digestion. To achieve the desired results, this medicine should be combined with lifestyle and dietary changes.

What is the difference between Xenical and Orlistat?

Orlistat is the active ingredient in both medications. There is 120mg found in both, and they work to block fat in the same way. The main difference is that Xenical is the branded version, and orlistat is the generic form. As such, Xenical is fractionally more expensive due to its branded name.

Why choose Xenical?

This treatment doesn’t just help you lose weight; it can help you to live longer and have a higher quality of life. Obesity can make every new day seem like a challenge. Weight management is a must in order to protect ourselves from the many related diseases, and Xenical can help you to:

  • Take control of your weight
  • Regain your youthful figure
  • Strive for a healthier body

Trials also showed that Xenical supported the maintenance of weight loss better than those trying to do it through a balanced lifestyle and willpower alone.

How Effective Is Xenical?

The active ingredient in Xenical is designed to attach itself to the digestive enzymes, which break down fat to allow it to be absorbed into your body. When using Xenical, 30% of this fat is blocked, and as such, you begin to naturally lose more weight than simply using calorie control and exercise alone.

When researched for one year across five separate trials, the average amount of weight lost by those using Xenical was 13.4lb compared to those in the placebo trial who were using exercise and healthy eating alone. The placebo group lost an average of 5.8lb, meaning that Xenical assisted in over double the loss of a healthy lifestyle alone.

Can I buy Xenical online?

Xenical can be purchased online through our website. You can take a free and confidential consultation with one of our professionals here at Click Pharmacy. We will assess your current medical situation, and if appropriate, we can prescribe you Xenical. You can then buy the tablets online through the site in different-sized packs depending on your preference, from 2 weeks worth up to 3 months.

What dose should I choose?

Each tablet contains 120mg of the active ingredient orlistat, which can be taken three times a day before a meal.

When deciding which pack size to initially purchase, you can speak to your doctor or ask your specialist at Click Pharmacy during your initial online appointment. They will be able to give you all the information and support you need.

How should I take Xenical?

You should take one of these tablets three times per day immediately before, during or shortly after your meals but no later than an hour after you eat, and you should not take the tablets after eating fat-free meals.

Taking more than three a day will not help you to lose any more weight, and if you miss a tablet, there is no need to worry; it simply means that you will not have received the benefit of the medication on that occasion. You can continue to take the tablets as normal when you next eat.

Due to its fat-blocking abilities, you should take a fat-soluble, daily multivitamin at least 2 hours before or after taking Xenical. Full instructions are provided with the medicine, and if you have any questions about how to take it, you can contact our expert team.

How does Xenical work?

Xenical works by inhibiting fat absorption in the gastrointestinal tract. Orlistat, which is the active ingredient in the tablets, is a lipase inhibitor and stops your body from taking in all the fat from your meals as free fatty acids. In turn, this makes it easier to lose weight. Bear in mind that eating food with a very high-fat content whilst taking Xenical can cause unpleasant gastrointestinal side effects, and as such, your meals should only contain 30% fat.

How Long do I take Xenical for before I notice a difference?

The weight loss from taking Xenical usually begins to show after around 14 days and, depending on your starting weight and weight target, can continue to drop for anywhere up to 1 year. In some cases, the weight loss will begin to plateau. This does not mean that the medication is no longer working; it simply means that you are beginning to maintain your weight loss using the drug rather than continuing to lose it.

What are the side effects of Xenical?

All medications are associated with certain potential side effects. Some of the most common in the case of Xenical are loose stools and gas with oily spotting, an increased number of bowel movements, an urgent need to have a bowel movement, a sore throat, headaches and sweating.

These side effects are most common when you first start taking Xenical as your body is getting used to the effects of the medication. If you find that these symptoms are persistent or worsen, it is advisable to speak to your GP or book an appointment online at Click Pharmacy to discuss your options and get advice.

Can I buy Xenical over the counter?

No, you can not buy Xenical over the counter. It would help if you had a valid prescription from your GP or pharmacist in order to purchase Xenical. It is a prescription-only drug.

Alternatives to Xenical

For some people, Xenical may not work. It may even be suitable for some. In such cases, seeking alternatives for the drug is crucial.

Xenical is the brand name drug for Orlistat. Orlistat is the generic version of the drug, available in 120 mg Capsules for a much more affordable price. Not only this, but you can also get the over-the-counter generic Orlistat, which is a lower 60 mg dose. The 60 mg capsules are known as Alli Capsules. The Alli slimming tablets contain the same active ingredient as Xenical. However, it contains half the dosage. It is a good OTC alternative for Xenical.

Generic medicines, such as Orlistat, are basically copies of brand-name drugs – containing the same amount of the active ingredient, with the same strength as well as effects. However, the critical difference is that they are typically cheaper.

Xenical warnings

Before starting Xenical, it is strongly encouraged to consult a GP. If you are overweight, there is a slight chance that you suffer from other health complications as a result of it. For instance, high blood pressure or hypertension is a common health problem among overweight individuals. Considering such factors before taking a weight loss treatment, such as Xenical, is vital.

Furthermore, Xenical can lead to some harmless changes in the bowel habits, such as fatty or oily stools. This occurs due to the elimination of undigested fat in the faeces.

Note that if you use oral contraception, switching to another contraceptive method is recommended. This is because the efficacy of oral contraception can be cancelled out if you experience severe diarrhoea due to Xenical.

Do not take Xenical or any other weight loss treatment if any of the following apply to you:

  • You are allergic to the active ingredient of Xenical
  • You are allergic to any of the ingredients of Xenical listed on the box
  • You have been diagnosed with chronic malabsorption syndrome
  • You have problems with your liver

How often should I take Xenical Capsules?

Depending on the severity of your case you may be advised to take Xenical Capsules differently. However you are generally required to take one capsule an hour after consuming a fat containing meal, this is usually three times a day.

Should I take a dose of Xenical Capsules if I skip a meal?

If you skip a meal, you should also skip your dose of Xenical Capsules. Taking Xenical Capsules on an empty stomach can cause serious harm to the body.

Why do I have to take Xenical Capsules after consuming a fat-containing meal?

It is important to take Xenical Capsules after consuming a fat-containing meal. This is because Xenical Capsules work by targeting the fat consumed with meals, if you have not consumed a meal the active ingredient could target the wrong type of fat and cause harmful side effects.

Can I use Xenical Capsules for weight loss if I am diabetic?

Xenical Capsules are suitable for use for diabetic patients however it is advised to regularly check your blood sugar levels. This is because there is a possibility that Xenical Capsules interfere with blood sugar levels.

Like all medicines, you may experience a number of side effects from using Xenical Capsules. Common side effects include:

  • Increased bowel movements
  • More urgent bowel movements
  • Changes in bowel function
  • Poor bowel and bladder control

If any of these side effects worsen you should stop using Xenical Capsules and seek medical advice, from a GP or pharmacist, as soon as possible.

Always read the patient information leaflet before starting your treatment. The patient information can be found here.
