FDA Issues Early Communication about Ongoing Safety Review of Orlistat.
Weight loss drug review includes both prescription drug Xenical and OTC drug Alli.

The U.S. Food and Drug Administration announced today that it is reviewing adverse event reports of liver injury in patients taking the weight loss drug orlistat, marketed as the prescription drug Xenical and the over-the-counter medication Alli.

Between 1999 and 2008, the FDA received 32 reports of serious liver injury in patients taking orlistat. Of those cases, 27 reported hospitalization and six resulted in liver failure. Thirty of the adverse events occurred outside the United States. The most commonly reported adverse events included yellowing of the skin or whites of the eyes (jaundice), weakness, and stomach pain.

The FDA is reviewing additional data submitted by orlistat manufacturers on suspected cases of liver injury, and the issue has been discussed at the FDA’s Center for Drug Evaluation and Research Drug Safety Oversight Board.

“The issues here are complex, but FDA has benefited from the input of the Board, including comments from representatives from three FDA Centers and several other Agencies in the Department of Health and Human Services,” said Steven Osborne, M.D., executive director of the Board.

The FDA’s analysis of these data is ongoing, and no definite association between liver injury and orlistat has been established at this time. Consumers taking Xenical should continue to take it as prescribed, and those using over-the-counter Alli should continue to use the product as directed.

For more information on the Early Communication about the ongoing safety review please read: Orlistat (Marketed as Alli and Xenical) Safety Review. The Early Communication is a risk communication tool used by the FDA to inform the public about its ongoing safety reviews of drugs. The FDA will release its findings on orlistat as soon as the review is completed.

Consumers who have used orlistat should consult a health care professional if they experience symptoms possibly associated with development of liver injury, particularly weakness or fatigue, fever, jaundice, or brown urine. Other symptoms may include abdominal pain, nausea, vomiting, light-colored stools, itching, or loss of appetite.

The FDA urges both health care professionals and consumers to report suspected side effects from the use of orlistat to FDA’s MedWatch Adverse Event Reporting program.

FDA’s Early Communication about the Ongoing Safety Review of Orlistat.

FDA is reviewing new safety information regarding reports of liver-related adverse events in patients taking orlistat. Orlistat is marketed in the United States as a prescription product, Xenical, and as an over-the-counter (OTC) product, Alli.

Xenical (orlistat 120mg) was approved as a prescription product by FDA in 1999 for obesity management in conjunction with a reduced caloric diet, and to reduce the risk of regaining weight after prior weight loss. In 2007, Alli (orlistat 60mg) was approved for OTC use for weight loss in overweight adults, 18 years and older, in conjunction with a reduced-calorie and low-fat diet. Currently, orlistat is approved for marketing in approximately 100 countries. In January 2009, a nonprescription version of orlistat was approved for sale in the European Union.

Between 1999 and October 2008, 32 reports of serious liver injury, including 6 cases of liver failure, in patients using orlistat were submitted to FDA’s Adverse Event Reporting System. Thirty of the 32 reports occurred outside the United States. The most commonly reported adverse events described in the 32 reports of serious liver injury were jaundice (yellowing of the skin or whites of the eyes), weakness, and abdominal pain. Hospitalization was reported in 27 of the 32 cases.

In addition to the 32 reported cases, this issue was discussed at the CDER Drug Safety Oversight Board in April 2009, and FDA is reviewing other data on suspected cases of liver injury submitted by the manufacturers of orlistat. FDA’s analysis of these data is ongoing and no definite association between liver injury and orlistat has been established at this time.

FDA is not advising healthcare professionals to change their prescribing practices with orlistat. 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.

Consumers should consult their health care professional if they are experiencing symptoms possibly associated with the use of orlistat and development of liver injury, particularly weakness or fatigue, fever, jaundice or brown urine. Other symptoms may include abdominal pain, nausea, vomiting, light-colored stools, itching, or loss of appetite.

FDA urges both healthcare professionals and consumers to report side effects from the use of orlistat (Alli and Xenical) to FDA’s MedWatch Adverse Event Reporting program.

This early communication is in keeping with FDA’s commitment to inform the public about its ongoing safety reviews of drugs. FDA will communicate its findings to the public as soon as its review of orlistat is complete.

This information reflects FDA’s current analysis of available data concerning these drugs. Posting this information does not mean that FDA has concluded there is a causal relationship between the drug products and the emerging safety issue. Nor does it mean that FDA is advising health care professionals to discontinue prescribing these products. FDA is considering, but has not reached a conclusion about whether this information warrants any regulatory action. The FDA will release an update when additional information or analyses become available.

People who use Reglan may be at risk to tardive dyskinesia. Recently published analyses suggest that Reglan, also known as metoclopramide, is the most common cause of drug-induced movement disorders. More than two million Americans use these products for the treatment of a number of gastrointestinal disorders depending on what form the physician prescribes the medication. The FDA has become aware of continued spontaneous reports of tardive dyskinesia in patients who used metoclopramide, the majority of whom had taken the drug for more than three months.
