Studies in 2004 had indicated that clobutinol has the potential to prolong the QT interval. Clobutinol was in 2007 determined to cause cardiac arrhythmia in some patients. Boehringer Ingelheim products containing clobutinol were voluntarily withdrawn from sale in Germany, and the rest of the world, on August 31, 2007. The approval for Germany and the EU was revoked in 2008.
