Monitoring
- Infusion associated reactions (IARs): Observe for IARs during and for two hours after infusion is finished. IARs may occur despite pre-treatment
- Monitor blood pressure, pulse, respiration and temperature as follows: (ref 3)
- Every 15 minutes for the first 30 minutes
- Then every 30 minutes during the infusion
- Then hourly for two hours post infusion
- If an IAR occurs, provide the appropriate symptomatic treatment, as needed. If the infusion is not well tolerated, the infusion time may be increased. If severe IARs occur, immediate discontinuation of the infusion should be considered. Refer to Q-Pulse CLN-NM-0118 for further information.
- The following monitoring requirements have been recently recommended (ref 4)
- Vital signs should be monitored before and during the intravenous infusion. If clinically significant changes are observed, discontinuation of infusion and additional monitoring, including ECG, should be considered
- Monitor LFTs. If patients develop signs of liver damage, unexplained liver enzyme elevations or symptoms suggestive of hepatic dysfunction (e.g. unexplained nausea, vomiting, abdominal pain, fatigue, anorexia, jaundice or dark urine), alemtuzumab should only be re-administered following careful consideration.
- Patients who develop signs of pathological immune activation should be evaluated immediately, and a diagnosis of haemophagocytic lymphohistiocytosis considered. Symptoms of immune activation may occur up to 4 years after the start of treatment.
