| Xenical medication is used with a reduced-calorie diet to help significantly overweight persons lose weight. It also helps to prevent regaining weight previously lost. Orlistat works by blocking some of the fat normally digested by the intestine. Before using this drug, tell your doctor your entire medical history, including any allergies (especially drug allergies), liver or kidney disease, high blood pressure or heart disease, history of stroke or seizures, certain eating disorders (e.g., anorexia nervosa), glaucoma (narrow angle), or history of gallstones. Limit alcohol intake, as it may worsen certain side effects of this medication. It is recommended that women of child-bearing age should use effective birth control while taking this medication. This drug is not recommended for use during pregnancy. Consult your doctor before using this drug. It is not known whether this drug is excreted into breast milk.

Elderly patients may be more sensitive to the effects of this drug. Use cautiously. Take this drug by mouth, generally three times daily during (or up to one hour after) each main meal that contains fat. Your daily intake of fat, protein and carbohydrate should be evenly spread over three main meals. If a meal is occasionally missed or contains no fat, skip that dose of the medication. Because this drug can interfere with absorption of fat-soluble vitamins (e.g., 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 this drug (e.g., at bedtime). The effects of this drug may begin as soon as 1-2 days after treatment begins; noticeable weight loss will take longer. If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.
