Latamoxef has been associated with prolonged bleeding time, and several cases of coagulopathy, some fatal, were reported during the 1980s. Latamoxef is no longer available in the United States. As with other cephalosporins with a methylthiotetrazole side chain, latamoxef causes an antabuse reaction when mixed with alcohol. Additionally the methylthiotetrazole side chain inhibits γ-carboxylation of glutamic acid; this can interfere with the actions of vitamin K.
It has been described as a third generation cephalosporin.
