The European Medicines Agency (EMEA) has completed a review of the safety and effectiveness of 'oral formulations' of medicines containing norfloxacin for the treatment of complicated pyelonephritis. The Agency's Committee for Medicinal Products for Human Use (CHMP) has concluded that the benefits of these medicines do not outweigh their risks for this type of infection, and that this indication should be removed from the marketing authorisations for these medicines throughout Europe. The review was carried out under an 'Article 31' referral1.

The use of other formulations of norfloxacin, such as injections, and its use for other diseases, were unaffected by the CHMP's review.

1 Article 31 of Directive 2001/83/EC as amended, referral under Community interest.
