The UK’s regulator of medicines (Medicines & Healthcare products Regulatory Agency [MHRA]) has received updated information from the company that makes Emerade pens about the defect previously reported by the MHRA. The defect means some pens may fail to activate and therefore will not inject adrenaline. Recent results from tests on unused pens returned by patients indicate that approximately 13% of pens (13 in 100) need higher than normal force to activate. This implies a higher risk of failure to activate than was previously estimated.
For Emerade 150 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 for a recall to patient level. Emerade 150 micrograms auto-injectors is a product intended for use in children who weigh between 15 kg and 30 kg (typically aged 3 to 10 years).

Emerade 300 microgram and Emerade 500 microgram auto-injectors are not being recalled at present as there are insufficient supplies of alternatives to provide replacements. For all patients currently in possession of higher strengths of Emerade auto-injectors (i.e. 300 or 500 microgram auto-injectors), the advice from MHRA and DHSC remains that the risk to the patient of being left without a pen, and therefore having no adrenaline to administer, is greater than allowing them to keep pens that may not activate, especially if two pens are carried. Although the risk of activation failure is now estimated to be higher than was previously reported, most Emerade pens will still activate as intended. Therefore, patients should be advised to retain their unexpired Emerade pens, to avoid being left without access to any adrenaline pens. Further MHRA drug alerts will be issued with immediate effect, as soon as supplies of alternatives are able to meet the demand for replacement of all the remaining Emerade pens held by patients.
