The combination with metamizole was removed from the market in Lithuania for safety reasons in 2000[3] and a boxed warning against use by children and adolescents was added in Serbia in 2005.[4] In 2016 India banned marketing of the combination with nimesulide along with 344 other combination drugs;[5][6] the order was overturned in December and appealed by the Government in January 2017.[7]
