Has anyone successfully used the "shrink wrap"-type vial covers for any of their high-alert medications? For reference, I was looking at the product available from Healthcare Logistics: https://shop.gohcl.com/default.aspx?page=item detail&itemcode=16063

We are specifically considering them for use with our neuromuscular blocking medications, as applying labels to the vials is problematic space-wise.

My concern is that it looks like the shrink wrap could possibly cover important vial labeling information.
