Xenical 賽尼可 blocks some of the fat that you eat, keeping it from being absorbed by your body.
Xenical 賽尼可 is used together with a reduced-calorie diet and weight maintenance to treat obesity in people with certain risk factors (such as diabetes, high blood pressure, and high cholesterol or triglycerides).
Xenical 賽尼可 may also be used for purposes not listed in this medication guide.
It is dangerous to purchase Xenical 賽尼可 on the Internet or from vendors outside of the United States. Medications distributed from Internet sales may contain dangerous ingredients, or may not be distributed by a licensed pharmacy. Samples of "alli" purchased on the Internet have been found to contain sibutramine (Meridia), a prescription weight loss medication that can have dangerous side effects in certain people. For more information, contact the U.S. Food and Drug Administration (FDA) or visit www.fda.gov/buyonlineguide.
Xenical 賽尼可 indications
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Xenical 賽尼可 is indicated for obesity management including weight loss and weight maintenance when used in conjunction with a reduced-calorie diet. Xenical 賽尼可 is also indicated to reduce the risk for weight regain after prior weight loss. Xenical 賽尼可 is indicated for obese patients with an initial body mass index (BMI) ≥30 kg/m2 or ≥27 kg/m2 in the presence of other risk factors (eg, hypertension, diabetes, dyslipidemia).
Table 1 illustrates body mass index (BMI) according to a variety of weights and heights. The BMI is calculated by dividing weight in kilograms by height in meters squared. For example, a person who weighs 180 lbs and is 5'5" would have a BMI of 30.

Uses of Xenical 賽尼可 in details
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Xenical 賽尼可 description
Xenical 賽尼可 is a drug designed to treat obesity. Its primary function is preventing the absorption of fats from the human diet, thereby reducing caloric intake. Xenical 賽尼可 works by inhibiting pancreatic lipase, an enzyme that breaks down triglycerides in the intestine. Without this enzyme, triglycerides from the diet are prevented from being hydrolyzed into absorbable free fatty acids and are excreted undigested.
Xenical 賽尼可 dosage
Xenical 賽尼可 Dosage
Generic name: Xenical 賽尼可 120mg
Dosage form: capsule
The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.
Recommended Dosing
The recommended dose of Xenical 賽尼可 is one 120-mg capsule three times a day with each main meal containing fat (during or up to 1 hour after the meal).
The patient should be on a nutritionally balanced, reduced-calorie diet that contains approximately 30% of calories from fat. The daily intake of fat, carbohydrate, and protein should be distributed over three main meals. If a meal is occasionally missed or contains no fat, the dose of Xenical 賽尼可 can be omitted.
Because Xenical 賽尼可 has been shown to reduce the absorption of some fat-soluble vitamins and beta-carotene, patients should be counseled to take a multivitamin containing fat-soluble vitamins to ensure adequate nutrition. The vitamin supplement should be taken at least 2 hours before or after the administration of Xenical 賽尼可, such as at bedtime.
For patients receiving both Xenical 賽尼可 and cyclosporine therapy, administer cyclosporine 3 hours after Xenical 賽尼可.
For patients receiving both Xenical 賽尼可 and levothyroxine therapy, administer levothyroxine and Xenical 賽尼可 at least 4 hours apart. Patients treated concomitantly with Xenical 賽尼可 and levothyroxine should be monitored for changes in thyroid function.
Doses above 120 mg three times a day have not been shown to provide additional benefit.
Based on fecal fat measurements, the effect of Xenical 賽尼可 is seen as soon as 24 to 48 hours after dosing. Upon discontinuation of therapy, fecal fat content usually returns to pretreatment levels within 48 to 72 hours.
Amiodarone: Xenical 賽尼可 may decrease the serum concentration of Amiodarone. Monitor therapy
Anticonvulsants: Xenical 賽尼可 may decrease the serum concentration of Anticonvulsants. Exceptions: Fosphenytoin; PENTobarbital; Thiopental. Monitor therapy

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in patients.
Commonly Observed (based on first year and second year data)
Gastrointestinal (GI) symptoms were the most commonly observed treatment-emergent adverse events associated with the use of Xenical 賽尼可 in the seven double-blind, placebo-controlled clinical trials and are primarily a manifestation of the mechanism of action. (Commonly observed is defined as an incidence of ≥ 5% and an incidence in the Xenical 賽尼可 120 mg group that is at least twice that of placebo.)

In general, the first occurrence of these events was within 3 months of starting therapy. Overall, approximately 50% of all episodes of GI adverse events associated with Xenical 賽尼可 treatment lasted for less than 1 week, and a majority lasted for no more than 4 weeks. However, GI adverse events may occur in some individuals over a period of 6 months or longer.
Discontinuation Of Treatment
In controlled clinical trials, 8.8% of patients treated with Xenical 賽尼可 discontinued treatment due to adverse events, compared with 5.0% of placebo-treated patients. For Xenical 賽尼可, the most common adverse events resulting in discontinuation of treatment were gastrointestinal.
Other Adverse Clinical Events
The following table lists other treatment-emergent adverse events from seven multicenter, double-blind, placebo-controlled clinical trials that occurred at a frequency of ≥ 2% among patients treated with Xenical 賽尼可 120 mg three times a day and with an incidence that was greater than placebo during year 1 and year 2, regardless of relationship to study medication.

In the 4-year XENDOS study, the general pattern of adverse events was similar to that reported for the 1- and 2-year studies with the total incidence of gastrointestinal-related adverse events occurring in year 1 decreasing each year over the 4-year period.
In clinical trials in obese diabetic patients, hypoglycemia and abdominal distension were also observed.
Pediatric Patients
In clinical trials with Xenical 賽尼可 in adolescent patients ages 12 to 16 years, the profile of adverse reactions was generally similar to that observed in adults.
Postmarketing Experience
The following adverse reactions have been identified during postapproval use of Xenical 賽尼可. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to Xenical 賽尼可 exposure.
Rare cases of increase in transaminases and in alkaline phosphatase and hepatitis that may be serious have been reported. There have been reports of hepatic failure observed with the use of Xenical 賽尼可 in postmarketing surveillance, with some of these cases resulting in liver transplant or death.
Rare cases of hypersensitivity have been reported with the use of Xenical 賽尼可. Signs and symptoms have included pruritus, rash, urticaria, angioedema, bronchospasm and anaphylaxis. Very rare cases of bullous eruption have been reported.
Rare cases of leukocytoclastic vasculitis have been reported. Clinical signs include palpable purpura, maculopapular lesions, or bullous eruption.
Acute oxalate nephropathy after treatment with Xenical 賽尼可 has been reported in patients with or at risk for renal disease.
Pancreatitis has been reported with the use of Xenical 賽尼可 in postmarketing surveillance. No causal relationship or physiopathological mechanism between pancreatitis and obesity therapy has been definitively established.
Lower gastrointestinal bleeding has been reported in patients treated with Xenical 賽尼可. Most reports are nonserious; severe or persistent cases should be investigated further.
Do not take Xenical 賽尼可 if you are pregnant. Weight loss is not recommended during pregnancy, even if you are overweight or obese.
You should not take this medication if you are allergic to Xenical 賽尼可, if you are pregnant, or if you have gallbladder problems or chronic malabsorption syndrome (an inability to absorb food and nutrients properly).
Before taking Xenical 賽尼可, tell your doctor if you have an underactive thyroid, a history of gallstones or pancreatitis, type 1 or type 2 diabetes, an eating disorder, liver or kidney disease, or if you take other weight-loss medications (prescription or over-the-counter).
Do not give over-the-counter Xenical 賽尼可 (alli) to a child younger than 18 years old. Prescription Xenical 賽尼可 should not be used by anyone age 12 to 18 without the advice of a doctor.
Xenical 賽尼可 should be used only by the person for whom it was prescribed. Never share Xenical 賽尼可 with another person, especially someone who has a history of eating disorder. Keep the medication in a place where others cannot get to it.
Xenical 賽尼可 is only part of a complete program of treatment that also includes diet, exercise, and weight control. Your daily intake of fat, protein, and carbohydrates should be evenly divided over all of your daily meals. Follow your diet, medication, and exercise routines very closely.
Avoid a diet that is high in fat. High-fat meals taken in combination with Xenical 賽尼可 can increase your risk of unpleasant side effects on your stomach or intestines.
