Xenical: A Comprehensive Guide Xenical, also known by its generic name Orlistat, is a prescription medication used to assist in weight loss. It is specifically used to treat obesity by reducing the absorption of fat from the diet. This article will cover the uses, dosage, demographics, side effects, interactions, and generic options of Xenical. Uses Xenical is used in combination with a low-calorie diet and exercise to help people lose weight. It works by preventing the absorption of some of the fat consumed through the diet. This fat is then passed out of the body through bowel movements. Xenical is approved for use in adults over the age of 18 with a body mass index (BMI) of 30 or greater. It is also approved for people with a BMI of 27 or greater who have other risk factors such as high blood pressure, diabetes, or high cholesterol. Dosage The recommended dose of Xenical is one 120-milligram capsule three times a day. It should be taken with each main meal that contains fat or within one hour of that meal. If a meal is missed or has no fat, the Xenical dose should be skipped. It is important to follow a low-calorie diet while taking Xenical since it is not a magic pill and cannot work without proper diet and exercise. Demographics Obesity is a global epidemic, affecting both men and women of all ages. According to the World Health Organization, in 2016, more than 1.9 billion adults were overweight, with 650 million of them being obese. Xenical is typically prescribed for adults over the age of 18 with a BMI of 30 or greater, although it is sometimes prescribed to those with a BMI of 27 or greater with other risk factors. Side Effects The most common side effects of Xenical are related to the digestive system. These include oily or fatty stools, gas, frequent bowel movements, and an urgent need to have a bowel movement. These side effects typically occur in the first few weeks of treatment and diminish as the body adjusts to the medication. Other less common side effects include an increased risk of kidney stones, liver problems, and allergic reactions. Interactions Xenical may interact with certain medications such as cyclosporine, warfarin, and levothyroxine. It may also reduce the absorption of some fat-soluble vitamins such as vitamin D, E, A, and K. Therefore, it is important to inform your doctor of any medications or supplements you are taking before starting Xenical. Generic Options Orlistat is the generic name for Xenical. It is available in both prescription and over-the-counter (OTC) formulations. The prescription strength is typically 120 milligrams three times a day, while the OTC strength is typically 60 milligrams taken up to three times a day with meals containing fat. It is important to note that the OTC version of orlistat only helps with weight loss and does not treat obesity. It is also important to confirm any and all changes to your medication with a doctor. Conclusion Xenical, also known as orlistat, is an FDA-approved medication used to help individuals lose weight. It is typically prescribed to people with a BMI of 30 or greater and can be taken in combination with a low-calorie diet and exercise. Side effects such as oily stools and increased bowel movements are common, but generally decrease as the body adjusts to the medication. Xenical can interact with certain medications and may affect the absorption of fat-soluble vitamins. It is important to talk to your doctor before starting Xenical and to follow a healthy diet and exercise routine while taking it.
