Alli and Xenical are undergoing a safety review because of reports linking the drugs to liver injuries. Alli, which is sold over-the-counter, and prescription Xenical are versions of orlistate.
Despite the ongoing safety review, the Food & Drug Admnistration (FDA) is not advising healthcare professionals to change their prescribing practices with orlistat. The agency said consumers currently taking Xenical should continue to take it as prescribed and those using over-the-counter Alli should continue to use the product as directed.
