Batches of ZeniPower hearing aid batteries could explode, the UK medicines watchdog has warned.
There is a “very low” risk that two batches of ZeniPower mercury-free hearing aid batteries could explode when in use or depleted, the Medicines and Healthcare products Regulatory Agency (MHRA) announced yesterday (March 10).
Due to a manufacturing fault, batteries with best before dates of August and September 2018 are at risk, it said.
Pharmacists stocking these batteries should remove them from their shelves immediately and return them to their original supplier, the MHRA said.
All other batches of the batteries are not affected, it said. "If in doubt, do not use the batteries," it added.
Patients should check their hearing aid batteries as a “precautionary measure”, the watchdog said. No adverse incidents resulting in an injury have been reported though the MHRA's Yellow Card safety monitoring system.
