    May be harmful if swallowed, inhaled or absorbed through the skin. May cause sensitization by skin contact, or if breathed in. May cause an allergic reaction. [Note: Cephalosporins and penicillins have similar chemical structures. Because of this, it is believed that those individuals who are allergic to one class of compounds may show an increased risk of cross-allergenicity when a member of the other class is encountered.] Toxicology not fully investigated.
