This medication is used with a doctor-approved exercise, behavior change, and reduced-calorie diet program to help you lose weight. It is used by certain overweight people, such as those who are obese or have weight-related medical problems. Taking orlistat can also help keep you from gaining back weight you have lost. Losing weight and keeping it off can lessen the many health risks that come with obesity, including heart disease, diabetes, high blood pressure, and a shorter life.Dietary fats need to be broken down into smaller pieces before the body can absorb them. Orlistat works by blocking the enzyme that breaks down fats in your diet. This undigested fat then 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 intake of calories.
How to use Orlistat Capsule
If you are taking the over-the-counter product to self-treat, read all directions on the product package before taking this medication.
If your doctor has prescribed this medication, read the Patient Information Leaflet if available from your pharmacist before you start taking orlistat and each time you get a refill. Take this medication as directed by your doctor, by mouth with liquid sometime 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 of the medication. To decrease the chance of unpleasant side effects, it is very 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 (fat-soluble vitamins including A, D, E, K), a daily multivitamin supplement containing these nutrients is recommended. Take the multivitamin at least 2 hours before or 2 hours after taking orlistat (such as at bedtime).
If you take cyclosporine, take it at least 3 hours before or after orlistat to make sure the full dose of cyclosporine is absorbed into your bloodstream. If you take levothyroxine, take it at least 4 hours before or after orlistat.
You should see some weight loss within 2 weeks after you start orlistat. Tell your doctor if your condition does not improve or if it worsens.
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 last or get worse, notify your doctor promptly.
If your doctor has directed you to use this medication, remember that your doctor 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.
Stop taking this medication and tell your doctor right away if any of these rare but serious side effects occur: symptoms of liver disease (such as nausea/vomiting that doesn't stop, severe stomach/abdominal pain, dark urine, yellowing eyes/skin), symptoms of kidney stones (such as back pain, pain when urinating, pink/bloody urine).
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
