Unclear how orlistat's mechanism can lead to liver damage. Likely a non-issue.
August 28, 2009
Orlistat is designed to act peripherally in the GI tract and studies have demonstrated negligible systemic absorption of orlistat. Patients suffering from liver damage are either hypersensitive to orlistat or have taken too much of the drug. It is likely that these cases of liver injury are unrelated to orlistat, since obesity predisposes patients for liver damage. But overall cases of liver damage are small compared to the total number of patients who have taken the drug over the years.
