Xenical is a weight loss drug that is available only by prescription from a licensed doctor or other healthcare professional. It is manufactured by the Roche pharmaceutical company. It is typically prescribed for individuals who are obese in order to help them to lose weight when they have been struggling to do so.
As a drug meant only for obese individuals, Xenical will be prescribed to patients whose Body Mass Index (BMI) is greater than 30, and whose weight puts them at greater risk of conditions such as high blood pressure, heart disease, high cholesterol, and diabetes. Without the proper BMI, you will not be prescribed this drug. This is because there is a risk of serious and potentially life threatening consequences if it is taken by individuals who are not significantly overweight.
Xenical helps with weight loss by blocking the absorption of up to a third of the fat that is consumed in foods. The fat that is not absorbed during digestion as a result of the use of this drug is expelled from the body with the rest of its waste. This product has been proven effective in clinical studies.
The primary active ingredient in Xenical is Orlistat. Its high performance in clinical studies makes many doctors and patients confident of the efficacy of this drug. Unfortunately, as a prescription drug, it is also associated with some unpleasant potential side effects. These include abdominal pain, headaches, trapped wind and flatulence, diarrhea, low blood sugar levels (hypoglycemia), and anxiety.
As Xenical works by blocking the absorption of some fat by the body, there is a risk that some nutrients will not adequately be absorbed, either. This is because many vitamins and minerals are fat soluble and are therefore absorbed by the body through fat digestion. Therefore, your doctor will likely advise you to take a form of multivitamin on a daily basis along with the use of this medication.
Your doctor will also likely recommend a lower-fat diet while you take Xenical because the more fat you eat, the more will be sent out of the body through defecation. Excess fat in the stool can lead to the side effects relating to gas, abdominal pain, and diarrhea. For this reason, it is advised that you carefully follow the doctor’s instructions for taking this pill, and consult him or her if you need advice relating to the foods that should be consumed and those that should be avoided.
