Product Overview:
Xenical, containing the active ingredient Orlistat, is a leading weight loss medication manufactured by Roche. It is specifically designed to aid in weight management by inhibiting the absorption of dietary fats. Each hard capsule of Xenical contains 120 mg of Orlistat, and this product comes in a pack of 84 capsules.
Indications:
Xenical is indicated for use in the management of obesity. It is prescribed to individuals who are overweight or obese and need assistance in losing weight or maintaining weight loss. The medication is used alongside a reduced-calorie diet and exercise program to achieve optimal results. It is suitable for adults with a Body Mass Index (BMI) of 30 kg/m² or higher, or for those with a BMI of 27 kg/m² or higher who have weight-related health conditions, such as hypertension or type 2 diabetes.
Mechanism of Action:
Orlistat, the active component of Xenical, works by inhibiting the action of pancreatic lipases, enzymes responsible for breaking down dietary fats into smaller molecules that can be absorbed by the intestines. By blocking these enzymes, Orlistat prevents approximately 30% of the dietary fat from being absorbed. The undigested fat is then excreted through the bowel, thus reducing caloric intake and contributing to weight loss.
Dosage and Administration:
- Dosage: The recommended dose of Xenical is one 120 mg capsule taken three times a day with each main meal containing fat. The medication should be taken during or up to one hour after the meal. If a meal is missed or does not contain fat, the dose of Xenical can be skipped.
- Administration: Capsules should be swallowed whole with a glass of water. They should not be chewed, crushed, or opened.
Contraindications:
Xenical is contraindicated in the following conditions:
- Known hypersensitivity to Orlistat or any of the other components of the capsule.
- Chronic malabsorption syndrome.
- Cholestasis (a condition where bile cannot flow from the liver to the duodenum).
- Pregnant or breastfeeding women (due to the potential risk to the fetus or infant).
Warnings and Precautions:
- Gastrointestinal Effects: Common side effects include oily or fatty stools, increased bowel movements, and abdominal discomfort. These effects are related to the fat-blocking action of Orlistat and are generally minimized by adhering to a low-fat diet.
- Nutritional Absorption: Prolonged use of Xenical may affect the absorption of fat-soluble vitamins (A, D, E, and K). Therefore, a multivitamin supplement should be taken daily, preferably at bedtime or at least 2 hours before or after taking Xenical.
- Kidney and Liver Function: Caution should be exercised in patients with kidney or liver impairments. Regular monitoring of liver function is recommended.
Drug Interactions:
Xenical may interact with certain medications, including:
- Cyclosporine: Reduced absorption of Cyclosporine may occur; it is recommended to separate the administration of Xenical and Cyclosporine by at least 3 hours.
- Warfarin: Monitor anticoagulant effects as Xenical can affect the absorption of vitamin K, which is crucial for blood clotting.
- Antiepileptic Drugs: Possible interaction with certain antiepileptic drugs such as Lamotrigine, affecting their effectiveness.
Side Effects:
Common side effects include:
- Gastrointestinal symptoms: oily spotting, flatulence with discharge, frequent bowel movements, and fecal urgency.
- Possible impact on the liver: signs of liver injury such as jaundice or dark urine may occur.
Serious side effects are rare but can include severe allergic reactions, liver damage, and persistent gastrointestinal symptoms. If any severe side effects occur, discontinue use and consult a healthcare provider.
Storage:
- Storage Conditions: Store Xenical capsules at room temperature (15-25°C or 59-77°F), in a dry place away from direct light and moisture. Keep out of reach of children.
Patient Counseling Information:
- Dietary Advice: To maximize the effectiveness of Xenical, patients should follow a nutritionally balanced, reduced-calorie diet with approximately 30% of calories from fat.
- Exercise: Incorporating physical activity into daily routines is essential for successful weight management.
- Consult Healthcare Provider: Patients should consult their healthcare provider regularly to monitor progress, assess weight loss, and address any side effects or concerns.
