MHRA Issues Important Alert for recall of Emerade 500mcg Auto-Injectors


MHRA Issues Important Alert for recall of Emerade 500mcg Auto-Injectors 

Results from manufacturer testing of Emerade auto-injectors recalled from patients in Europe indicate that approximately 13% of pens need higher than normal force to activate, implying a higher risk of activation failure than was previously understood. This applies to all strengths of Emerade. Previous estimations of activation failure were obtained from tests on pens that had been stored in the manufacturing facility. Whereas, the recent results were obtained on pens carried by patients, suggesting an environmental contribution to the risk. Investigations are ongoing to understand this.

For Emerade 500 micrograms auto-injectors, the MHRA, in conjunction with the Department of Health & Social Care (DHSC) has established that there are sufficient supplies of alternative auto-injectors to allow a recall to patient level.

The recall of Emerade 500 microgram auto-injectors from patients follows a previous recall of Emerade 150 microgram auto-injectors and Emerade 300 microgram auto-injectors from patients. More information on the previous alert can be found on the following links:

Class 2 Medicines Recall: Emerade 150 micrograms solution for injection in pre-filled syringe, PL 33616/0013 (EL(20)A/14)


Class 2 Medicines Recall: Emerade 300 micrograms solution for injection in pre-filled syringe, PL 33616/0014 (EL(20)A/20)


Alternative brands of adrenaline auto-injector (EpiPen and Jext) are available in a maximum strength of 300 micrograms. There is evidence to suggest that a single EpiPen (300 microgram) or Jext (300 microgram) pen will be a suitable replacement for a single Emerade 500 microgram pen. This is based on recently available results from a study which compared blood levels of adrenaline following injection of Emerade 500 microgram pens with those following EpiPen 300 microgram or Jext 300 microgram pens. You must continue to always carry two adrenaline pens with you at all times. Prescribers are to follow dosage guidance in individual Summary of Product Characteristics (SmPC).

What to do if you suspect anaphylaxis

  • use your adrenaline pen immediately or ask someone else to do this if you prefer (any person is legally allowed to administer adrenaline to another person to save a life);
  • call an ambulance (999) immediately after giving the injection or ask someone to do this. Say this is an emergency case of anaphylaxis (pronounced "anna-fill-axis");
  • use your second adrenaline pen 5 to 15 minutes after the first pen if you are not improving or if you start to deteriorate after an initial improvement;
