The European Medicines Agency is to update the side effect profile for semaglutide following evidence from epidemiological studies that use of the drug is associated with a very rare eye condition known as non-arteritic anterior ischaemic optic neuropathy (NAION). This may cause loss of vision. The decision was announced on 6 June and will affect the labelling of three approved semaglutide products, Ozempic, Rybelsus and Wegovy. All three are produced by Novo Nordisk A/S and are on the market in the EU.
