The manufacturer of Emerade, the adrenaline injector, have informed us there is a small chance of product failing to deliver a dose of adrenaline from the syringe due to blockage of the needle.
However, if the patient follows the existing advice to carry two in-date pens with them at all times, the risk of not being able to deliver a dose of adrenaline before the emergency services arrive is substantially reduced.
It should be emphasised that two pens are already recommended to be carried at all times in case the patient does not improve after the first injection which may occur for a number of reasons.
This notification of potential for needle blockage applies to Emerade devices of all strengths. It does not apply to the other marketed brands of adrenaline auto-injectors.
The MHRA is not recalling batches of Emerade so please do not request replacement devices unless they are expiring.
