How To Buy Xenical

Xenical can be bought online after your doctor has first prescribed it safely. Recurrent prescriptions can be bought online after an online medical consultation.

To obtain Xenical you should have a body mass index (BMI) of 30 or over. Xenical is sometimes prescribed to those with a BMI of 28 if there are also risk factors such as high blood pressure or type 2 diabetes.

The active ingredient in Xenical is called Orlistat. Individuals whose weight is putting them at risk of serious illness and death should speak to their doctor about using Xenical as a prescription.

There are other weight loss medications available over the counter that claim to use fat-binding as a weight loss mechanism. These may or may not work in some capacity, but are not suitable for obese and severely obese individuals.

Herbals remedies that claim herbs speed up metabolism are unregulated and not clinically proven. At best they may help in slight amounts at worst they will damage your health and prevent you from losing the weight you need to reduce your risk of life-threatening illnesses.

Is it safe to order online?

It is extremely important to buy Xenical from a registered online pharmacy that only dispenses genuine medicines. You will need to undertake an online consultation with a registered doctor before being prescribed Xenical online. Any website that is willing to sell you 'Xenical' without a prescription is putting your heath at risk. There are no guarantees that their medicines are genuine.

The fat loss market is lucrative. Many companies and brands attempt to sell wonder drugs that burn away fat without effort. These types of 'drugs' do not work. The only available medically prescribed fat loss medicine is Xenical, and this works with a combination of dietary change and exercise.

It is not worth risking your health and money on 'medicines' that are not clinically proven and claim to remove fat without effort.

What is included in the price?

When ordering Xenical online here at Medilico, this is an all-inclusive price including the prescription, consultation, medication and delivery. There are no hidden costs. The price adjusts depending on the dosage and quantity you have ordered.

Can you buy without a prescription?

No. All clinically proven medication requires a valid prescription and Xenical is no exception. This is to confirm the medication is perfectly safe and highly effective for you to use. The prescription process will involve a short consultation – this is the same in person as well as online – and involves medical and personal question to ensure Xenical is compatible with you. For Xenical, it's important to remember the BMI factor.

What Is Xenical Used For?

Xenical is used to help obese individuals lose weight and regain control of their health. If you have a BMI of over 30, or over 28 with complications such as type 2 diabetes or high blood pressure, Xenical may be prescribed to help you reduce your weight to a healthy level.

Losing weight can reduce the risk of serious health conditions such as cancer, heart disease and diabetes. Xenical is usually only prescribed to those who have tried conventional methods of weight-loss including a modified diet and exercise but have not been able to reduce their weight to a safe level.

Xenical is not usually prescribed to children under the age of 12. Only adults over the age of 18 can purchase Xenical online.

It's important to be aware that although Xenical is a weight-loss medication it will only work if you eat a healthier diet and regularly exercise.

How Does Xenical Work?

Xenical is a lipase inhibitor. It works by blocking fat that's been eaten as part of an everyday meal.

Lipases are the digestive system's enzymes. They work by breaking down fat so the body can absorb and store it. The active ingredient in Xenical is Orlistat. Orlistat binds itself to the lipase enzymes and prevents them from breaking down fat. Instead of being stored on your body 30% of consumed fat is passed straight through the bowels.

Unblocked fat is digested and stored as body fat, but once Xenical is in your digestive system it blocks around a third of the fat you've eaten. Because this fat is not digested it's eliminated in by your body and passed out as a bowel movement.

Xenical must be used in association with lifestyle changes. You will need to exercise and eat a low calorie diet. This is because fat from sugar and other foods will not be affected. Simply over-eating and using Xenical will not help you lose the weight you need. Speak to your doctor about a healthy eating plan and regular but gentle exercise. Beginning slowly will enable you to lose weight and keep going. As you lose weight exercising will become easier.

Xenical does not affect your mood like previous weight loss drugs on the market. Its active ingredient Orlistat simply prevents enzymes from digesting fat. It is not an appetite suppressor which tricks the brain into thinking it's full. Previous weight loss drugs on the market have been withdrawn over safety concerns these were sibutramine and rimonabant.

Fat blocking medication is preferable because you don't have to completely change your diet. Crash dieting is not required and although healthy choices are needed you will not need to cut out every gram of fat or sugar. This means you're more likely to stick to your weight loss plan and achieve a healthy BMI on Xenical.

Appetite suppressors change the way your brain functions, which can lead to psychological side effects. Xenical is not an appetite suppressant and does not affect your brain in any way.

How To Take Xenical

You must take Xenical as your doctor has prescribed it. Generally, you will be advised to take one 120mg tablet with a drink of water at some point before, during, or up to an hour after your meal. Using more Xenical than prescribed will not block more fat and you may experience side effects if you take more than the recommended amount.

Xenical blocks fat from being digested, but this can include some necessary vitamins including fat-soluble vitamins A, D, E and K. To counteract this effect you will need to take a multivitamin each day two hours before or after you take Xenical.

If you miss a meal or eat a meal containing no fat a dose of Xenical is not required as it will only prevent fat from being absorbed. It does not remove current body fat.

Your Diet

The diet you adopt with Xenical should consist of fruit and vegetables with an average 30% of calories from fat. These calories should be spread across three meals at breakfast, lunch and dinner.

Avoid snacking on fattening foods between meals as Xenical will not block any of this intake. If you do snack choose healthy options such as fruit, nuts and low-fat yoghurt. If you take Xenical at mealtimes but eat excessive snacks between meals Xenical will not help you lose weight. Lifestyle changes including regular exercise and a lower calorie diet are necessary to obtain the full benefit.

Lifestyle changes are also necessary and should be in place for when you stop taking Xenical. If eating and exercising habits have not changed then your lost weight is likely to be regained.

If you forget Xenical you can take it up to an hour after your last meal and it will still work. Don't double up on a dose as this can lead to side effects. If you miss more than one dose ask your doctor for advice.

Xenical hard tablets are not designed to be broken, crushed or chewed. The tablet should be swallowed whole without tampering.

How Long Is A Course of Xenical

You must lose at least 5% of your weight from three months of starting Xenical. If not the treatment should be stopped. If you continue to lose weight after six months then you can continue to use if for several years until your weight is at a safe level. You doctor will decide if it's safe and appropriate to keep prescribing Xenical to you.

If you take it correctly you should start to see improvements in two to three months. Sometimes individuals see progress as quickly as two weeks.

In short, Xenical can be taken until you have reached your target weight and your health is no longer in danger - so long as you are still losing weight.

Xenical Doses

Xenical is the only prescription weight loss medicine in the UK that is clinically proven to aid weight loss. It is only available in a 120mg tablet dose. One tablet should be taken three times a day with your meals.

Don't be tempted to increase your dose as this puts you at risk of side effects and won't remove any extra fat over and above the 30%.

Taking Xenical should become part of your daily eating regime. Choose a time to take Xenical, either before, during or up to an hour after your meal and stay with this pattern for all three meals.

What Is The Success Rate Of Xenical

Research has shown that Xenical is a highly effective weight-loss support.

Trials indicated that by using the active ingredient Orlistat the average weight loss was 50% higher than a placebo. Those taking Orlistat were also more likely to keep the weight loss rather than regaining it.

Other studies have shown that Xenical plus exercise and a healthier diet help individuals lose 10% of their body weight within six months compared to weight loss without Xenical.

However, the success rate is largely down to your lifestyle habits. If you eat excessively Xenical will remove 30% of the fat, but 70% of the remaining fat may still exceed what you burn away in exercise. If you eat more calories that you burn off you will gain weight.

To be successful Xenical must be viewed as an aid rather than a cure. Changing your lifestyle is important not only to reduce your weight when taking Xenical but in the period after you stop. Weight regain may happen if you don't change your eating and exercise habits into a healthy, sustainable regime.

Xenical Side Effects

Xenical is a prescription medicine and as with all prescription medicines it may produce unwanted side effects.

If you experience side effects that are severe and you are unable to cope with them, speak to your doctor. The majority of individuals using Xenical do so without problems, but you should be aware of the following potential side effects.

A very common side effect affecting more than one in ten users is the effects of Xenical on bowel habits. Xenical works by blocking fat from absorption so 30% of fat is passed straight through your gut. This can mean you experience fatty, oily stools, liquid stools, flatulence, flatulence with discharge and a strong desire to open your bowels. This can lessen over time as your body becomes used to the action of Xenical, particularly if you eat the recommended lower fat diet. Eating a high-fat diet may increase the risk of these symptoms.

Other very common side effects include headaches, abdominal discomfort, and lowered blood sugar in type 2 diabetics.

Common side effects affecting one to 10 users in 100 include soft stools, stool incontinence, bloating in type 2 diabetes, tooth and gum problems, changes to the menstrual cycle, rectal pain and discomfort and tiredness.

Other rare side effects include:

Severe liver problems. Symptoms experienced are loss of appetite, itchy skin, yellowing skin or eyes (Jaundice) an orange-coloured urine, light colour stool, pain in the top right of your stomach.

Kidney problems. Before you begin Xenical you may need kidney tests to check their function. Symptoms of kidney problems include swelling of the feet and legs, a small volume of urine, painful and frequent urination, blood-stained urine, loss of appetite, nausea, vomiting, and severe stomach groin or back pain.

Gallstones. Symptoms are a pain in the right-hand side of your stomach, nausea, chills, vomiting and shoulder pain.

An allergic reaction is a serious but rare side effect. Symptoms are itching, itchy raised skin patches, hives, difficulty breathing, nausea, vomiting, swollen lips and a swollen throat.

Other rare side effects include rectal bleeding, pancreatitis, diverticulitis, and skin blistering.

If you experience any rare but serious side effects stop taking Xenical and speak to your doctor. Ignoring serious side effects can lead to a life-threatening conditions. Serious side effects are rare, but a change in bowel movement is to be expected. Your doctor may recommend lowering the amount of fat you eat and managing any symptoms.

Xenical Precautions

Any weight loss experienced by users of Xenical may affect other medicines. You may need to have any dose of high cholesterol or diabetes drugs changed. Speak to your doctor about the implications of weight loss on your current medications.

Xenical or any weight loss medicines should not be taken by children unless your doctor recommends it. Children's bodies are still developing and any lack of vitamins or minerals can cause problems in later life.

Never share your medicine with anyone and keep it out of the reach of children.

Other Medication Interactions

It's important to let your doctor, dentist and pharmacist know if you are taking Xenical, and report any recent medicines you've taken to them. This is important because the combination of medicines can strengthen or weaken their effects.

Xenical may modify the activity of:

  • The contraceptive pill: If you take an oral contraceptive such as the combined or mini pill you should ensure you use extra barrier contraception for seven days following severe diarrhoea. Severe stomach upsets can mean the pill is not properly absorbed leaving you at risk of pregnancy. If you experience regular diarrhoea using Xenical speak to your doctor about using another form of contraception.
  • Anticoagulant drugs such as warfarin. Your doctor may need to monitor your blood levels to ensure you do not experience bleeding.
  • Ciclosporin. Using Xenical with ciclosporin is not recommended. Your doctor may need to monitor your blood levels.
  • Iodine salts and thyroid medications. Xenical may interfere with how thyroid medicines work leading to cases of hypothyroidism.
  • Amiodarone for heart rhythm problems.
  • Antiretrovirals used to treat HIV.
  • Medicines for depression, psychiatric disorders or anxiousness.
  • The active ingredient orlistat may decrease the absorption of antiepileptic drugs.
  • Xenical is not recommended for people taking acarbose - an anti-diabetic drug for diabetes mellitus.

If you are required to take a short or long course of medicines always inform you doctor, dentist or pharmacist that you are taking Xenical. All over-the-counter remedies and any herbal supplements should be evaluated against Xenical in case there is a risk of interaction.

If you feel Xenical is reacting with a medicine you have taken speak to your doctor for advice.
