Slimming products Xenical

Xenical is a specific gastrointestinal lipase inhibitor with a long-term effect. Its therapeutic effect is carried out in the lumen of the stomach and small intestine and consists in the formation of a covalent bond with the active serine part of the stomach and pancreatic lipase. The inactivated enzyme loses the ability to break down food fats in the form of triglycerides into absorbed free fatty acids and monoglycerides. Since undissolved triglycerides are not absorbed, the resulting decrease in calorie intake leads to a decrease in body weight. Thus, the therapeutic effect of the drug is carried out without absorption into the systemic blood flow.

How to use Xenical


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.

Precautions


Before taking orlistat, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using this medication, tell your doctor or pharmacist your medical history, especially of: a certain digestive problem (chronic malabsorption syndrome), a certain gall bladder problem (cholestasis), underactive thyroid (hypothyroidism), kidney stones/problems (such as calcium oxalate kidney stones, hyperoxaluria), certain eating disorders (anorexia nervosa/bulimia), HIV infection, seizures. Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). 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 doctor may need to adjust your diabetes medication, exercise program, or diet. This medication must not be used during pregnancy. Weight loss offers no potential benefit to a pregnant woman and may harm an unborn baby. If you become pregnant or think you may be pregnant, tell your doctor right away. It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.
