MonitorResponse to therapy
Monitor patient's response to therapy. Notify health care provider if infection does not appear to improve or worsens.Side effects
Monitor patient for GI, DERM, and general body side effects, and signs of superinfection. Inform health care provider if noted and significant. Immediately report severe diarrhea, diarrhea containing blood or pus, or severe abdominal cramping.
Category B .
