Brief description of the problem
Bayer plc has informed us that they have received two complaints globally concerning Mirena inserters with an insertion tube which is mounted inversely to the handle. This has resulted in inversion of the insertion depth scale, which may lead to incorrect insertion depth and the possibility of a reduced efficacy or adverse events. A very small number of Mirena inserters may potentially be affected by this issue.
An investigation has shown that both complaints involve one batch of inserters and Mirena batch TU01BPE has been manufactured using inserters from the same batch.
Any incorrectly mounted insertion tubes identified should be reported to Bayer plc by telephone,
01635 563116 or by email to medical.information@bayer.co.uk
