Strong oxidizing agents.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
Exposure Effects - Inhalation:
Apnoea has developed secondary to seizures following overdose. - Pulmonary infiltrates with eosinophilia has occurred with chronic therapeutic use. Bronchoconstriction and asthma has been reported after initial dosing.
Exposure Effects - Skin:

CNS depression and seizures (focal and generalized) have occurred following overdose. A. Dizziness and dystonic movement disorders have also been reported. With therapeutic use - aseptic meningitis has been associated with naproxen.
The use of Naproxen should be avoided during pregnancy as insufficient studies have been performed. Because of known effects on the foetus (closure of ductus arteriosus), it should certainly be avoided during late pregnancy.
Naproxen has been found in the milk of lactating women; however, The American Academy of Paediatrics considers naproxen to be compatible with breast feeding (Briggs et al, 1998).
