orlistat – oral, Alli, Xenical
Medication Uses How To Use Side Effects Precautions Drug Interactions Overdose Notes Missed Dose Storage USES: This medication is used with a doctor-approved reduced-calorie diet, exercise, and behavior modification program to help significantly overweight persons lose weight. Taking orlistat can also help prevent regaining lost weight and reduce health risks associated with obesity including heart disease, diabetes, high blood pressure, certain forms of cancer, breathing problems, and a shorter life span.
Dietary fats need to be broken down before the body can absorb them. Orlistat works by blocking the enzyme that breaks down fats in your diet. This undigested fat passes out of your body in your bowel movement. Orlistat does not block the absorption of calories from sugar and other non-fat foods, so you still need to restrict your total calorie intake.
HOW TO USE: If you are using the over-the-counter product, read all directions before taking this medication. If your doctor has prescribed this medication, read the Patient Information Leaflet if available from your pharmacist before starting orlistat and each time you get a refill. Take this medication as directed by your doctor, by mouth with liquid during each meal that contains fat or within 1 hour after the meal, usually 3 times daily. If you miss a meal or your meal contains no fat, skip that dose. To decrease the chance of side effects, it is important that no more than 30% of the calories in your diet come from fat. Your daily intake of fat, protein, and carbohydrates should be evenly spread over 3 main meals.
Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase. Because this drug can interfere with the absorption of certain vitamins, a daily multivitamin supplement containing these nutrients is recommended. Take the multivitamin at least 2 hours before or after taking orlistat. If you take cyclosporine, take it at least 3 hours before or after orlistat. If you take levothyroxine, take it at least 4 hours before or after orlistat.
You should see some weight loss within 2 weeks after starting orlistat. Tell your doctor if your condition does not improve or worsens.
SIDE EFFECTS: Changes in your bowel function often occur because of the unabsorbed fat. Fatty/oily stool, oily spotting, intestinal gas with discharge, a feeling of needing to have a bowel movement right away, increased number of bowel movements, or poor bowel control may occur. These side effects may get worse if you eat more fat than you should. If these effects persist or worsen, notify your doctor promptly. If your doctor has directed you to use this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
