Drug Information Update - Serious Liver Disorder Associated with the Use of Videx/Videx EC (didanosine)

The Division of Drug Information (DDI) is CDER's focal point for public inquiries. We serve the public by providing information on human drug products and drug product regulation by FDA.

The U.S. Food and Drug Administration (FDA) is alerting healthcare professionals and patients about a rare, but serious, complication in the liver known as non-cirrhotic portal hypertension in patients using Videx or Videx EC (didanosine). Didanosine is a medication used to treat human immunodeficiency virus (HIV) infection. Videx was the first approved didanosine medication. Videx EC is a delayed-release version of Videx.

Non-cirrhotic portal hypertension (portal hypertension that is not caused by cirrhosis of the liver) is rare in the United States. It occurs when blood flow in the major vein in the liver (the portal vein) slows down. This slowed blood flow can lead to the development of severely enlarged esophageal veins (varices) in the gastrointestinal system. Because esophageal varices are thin and portal hypertension increases the pressure of blood flow in these veins, esophageal varices can break open. This can result in serious bleeding and, in some cases, death.

FDA became aware of cases of non-cirrhotic portal hypertension through adverse event reports submitted to FDA's Adverse Event Reporting System (AERS). Based on these reports, FDA has revised the didanosine drug label to include information about non-cirrhotic portal hypertension to help ensure the safe use of this drug.
