My husband has been taken off glicazide because his blood sugar number had dropped to 43, he is still on metformin. However his readings are now increasing, has gone from always being the 5s before breakfast to in the 7s or even 8s. quite often 2 hr after his main meal in the evening he is 13 or 14 it really worries me and I wondered there were any other medications that he might need to keep him on a even keel.
