Xenical Oral

Uses 
This medication is used along with a doctor-approved reduced-calorie diet, exercise, and behavior modification program to help significantly overweight (obese) persons lose weight. Taking orlistat can also help prevent you from regaining the weight you have lost. Losing weight and keeping it off can reduce the many health risks that come with obesity, including heart disease, diabetes, high blood pressure, some forms of cancer, certain breathing problems, and a shorter lifespan.

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 Xenical Oral

Read the Patient Information Leaflet provided by your pharmacist before you start taking orlistat and each time you get a refill. If you have any questions, consult your doctor or pharmacist.

Take this medication by mouth with liquid sometime during each main meal that contains fat or within 1 hour after the meal, usually 3 times daily or as directed by your doctor. If you occasionally 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 carbohydrate should be evenly spread over 3 main meals.

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 (e.g., at bedtime).

If you take cyclosporine, take it at least 2 hours before or after orlistat to make sure the full dose of cyclosporine is absorbed into your bloodstream.

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.

Before taking orlistat, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies.

This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: digestive problems (chronic malabsorption syndrome), gall bladder problems (cholestasis).

Before using this medication, tell your doctor or pharmacist your medical history, especially of: underactive thyroid (hypothyroidism), kidney stones/problems (e.g., calcium oxalate kidney stones, hyperoxaluria), certain eating disorders (anorexia nervosa/bulimia).

If you are diabetic, weight loss may improve your blood sugar control. Be sure to check your blood sugar regularly and tell your doctor the results. Your diet or medications may need to be adjusted.

This medication is not recommended for use during pregnancy. Consult your doctor for more details.

It is not known whether this drug passes into breast milk. Because of the possible risk to the infant, breast-feeding while using this drug is not recommended. Consult your doctor before breast-feeding.

For best results, this medication should be used along with a doctor-approved exercise program and diet plan. Consult your doctor or dietician for help designing an appropriate exercise and food plan for you.

MISSED DOSE:

If you miss a dose, take it as soon as you remember unless it has been more than 1-2 hours since your meal. In that case, skip the missed dose since most of the fat from your meal will already be absorbed and the medication will not work. Do not double the dose to catch up.

Changes in your bowel function frequently 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.
