User avatar Dear violinchezy,
It is good, that you have read the side effects and this is what every body should do for any medication he has to take. The most commonly observed adverse events in seven double blind studies using XENICAL was gastrointestinal upset which was related to the mechanism of action of XENICAL. GI disturbances included, abdominal pain, nausea, infectious diarrhoea, fecal urgency, rectal discomfort, fatty/oily stool, particularly after meals containing higher fat than recommended. These events occurred within 3 month of therapy but they were mild and transient for one week in most of the cases. However, from these studies XENICAL is contraindicated in patients with chronic malabsorption syndrome or cholestasis. I recommend you to go back to your doctor and discuss with him your fears to better understand his advice and to be aware more of warning symptoms that mandate therapy discontinuation, if he still believe that you can receive the drug.
Best regards,
