Description
Xenical, known by its generic name orlistat, is a prescription medication that is primarily used for weight management. It works by inhibiting the absorption of dietary fat in the digestive tract. By blocking the action of enzymes called lipases, Xenical prevents the breakdown of fat into smaller molecules that the body can absorb. As a result, only a portion of the dietary fat you consume is absorbed, and the excess fat is excreted through the bowel. This helps reduce calorie intake and can assist with weight loss.
Xenical is typically prescribed to individuals who are overweight or obese and are unable to lose weight through diet and exercise alone. It can be used in combination with a reduced-calorie diet and increased physical activity to help people achieve and maintain a healthy weight. Xenical is also sometimes used to treat obesity-related conditions like type 2 diabetes, high blood pressure, and high cholesterol levels.
How Xenical Works
The primary mechanism of Xenical is to block the enzyme lipase, which is responsible for breaking down fat in the stomach and intestines. Without the action of this enzyme, around 25% of the dietary fat you consume is not digested and is passed out of the body. This results in a reduction of total calorie intake, which can contribute to weight loss when combined with a healthy diet and exercise routine.
By blocking fat absorption, Xenical can also help improve other obesity-related health issues, including high cholesterol and high blood sugar. It’s important to note that Xenical is not a magic solution; it requires commitment to a healthy lifestyle to see significant results.
Uses of Xenical
- Weight Loss: Xenical is used to help overweight and obese individuals lose weight when combined with a calorie-controlled diet and exercise.
- Obesity-Related Health Conditions: It is often prescribed to people who have type 2 diabetes, high blood pressure, or high cholesterol, as Xenical may help with weight management and improve overall health.
- Weight Maintenance: After achieving weight loss, Xenical can be used as part of a maintenance program to help keep the weight off and avoid regaining lost pounds.
Dosage and Administration
- How to Take Xenical: Xenical is usually taken three times a day, with each meal that contains fat. It is important to take the medication with or up to an hour after eating a meal to ensure that it is effective.
- Recommended Dosage: The typical dose of Xenical is 120 mg taken with each of the three main meals of the day. If a meal is missed or contains no fat, a dose of Xenical can be skipped.
- How to Take: Swallow Xenical capsules whole with a glass of water. It is important to follow a balanced diet that includes appropriate amounts of fat, protein, and carbohydrates to support the weight loss process while using this medication.
Side Effects of Xenical
While Xenical can be effective in helping individuals lose weight, it can cause some side effects, especially in the digestive system, due to its fat-blocking action.
- Common Side Effects:

- Severe gastrointestinal symptoms like nausea, vomiting, or diarrhea.
If you experience any serious side effects or signs of liver or kidney problems, contact your healthcare provider immediately.
Precautions and Warnings

- Liver or Kidney Issues: If you have liver or kidney problems, talk to your doctor before starting Xenical, as it may exacerbate existing conditions.

- Eating Disorders: Xenical should not be used in individuals with eating disorders, such as bulimia or anorexia, due to the risk of serious health complications.
