Labeling errors & mix-ups

This is exactly what it sounds like: the wrong label on the right product, the wrong strength printed on the bottle, a missing or illegible lot number and expiry date, or two products mixed up during packaging. It is dangerous precisely because the pill or liquid itself may be fine, yet the patient has no way of knowing what they are actually taking. A high share of the Class I recalls in this group are mix-ups where a stronger product ended up in a weaker product's packaging.
