• Anaphylactic and Hypersensitivity Reactions

What special precautions should I follow?

• Laboratory abnormalities in liver tests have been seen in healthy volunteers and pediatric patients treated with Eraxis. Patients who develop abnormal liver tests during Eraxis therapy should be monitored for evidence of worsening hepatic tests and evaluated for risk/benefit of continuing Eraxis therapy.
