What are the most common adverse events seen with XENICAL?
The most commonly reported 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. These and other commonly observed events were generally mild and transient, and decreased markedly during the second year of treatment. Withdrawal rates due to these events in clinical studies were low. Patients should be educated to expect GI events when taking XENICAL.
