The most commonly observed adverse events (incidence of >5%
and twice that of placebo) were oily spotting, flatus with discharge, fecal
urgency, fatty/oily stool, oily evacuation, increased defecation and fecal
incontinence, particularly after meals containing more fat than
recommended. These and other commonly
observed events were generally mild and transient, but for some people they may
continue for 6 months or longer.
XENICAL is contraindicated in patients with chronic
malabsorption syndrome or cholestasis. Organic causes of obesity, such as
hypothyroidism, should be excluded before prescribing XENICAL. XENICAL is
not recommended for use during pregnancy and should not be taken by nursing
mothers.
To reduce the chance of a drug interaction resulting in
reduced levels of cyclosporine, XENICAL and cyclosporine should not be taken
within 2 hours of each other. More
frequent monitoring of cyclosporine levels should be considered in patients
taking both drugs (see WARNINGS).
Because XENICAL has been shown to reduce the absorption of
some fat-soluble vitamins and beta-carotene, patients should be counseled to
take a multivitamin supplement containing fat-soluble vitamins once a day at
least 2 hours before or after taking XENICAL.
