Special warnings and precautions for use Contact lenses should not be worn/used when Fusidic acid eye drops are used. The microcrystalline fusidic acid may cause scratches in the contact lens or cornea. Contact lenses are kept out until all symptoms of the infection have gone. Bacterial resistance has been reported to occur with the use of fusidic acid. As with all antibiotics, extended or recurrent use may increase the risk of developing antibiotic resistance.
