Whenever possible, get another member of staff to look at the script and either label it, or assemble it, but avoid doing it all yourself if you can. This is not out of laziness, but sometimes our eyes deceive us and see something that isn't really there, and by making 2 pairs of eyes work on a script, you minimise the risk that you BOTH saw something different from what is actually on the Rx.
If you don't have someone else to double-check you, try reading out loud what the script says, what the label says, and what the box says: it's a different part of your brain that processes speech, sounds, and language, so if your eyes have convinced you that the Rx says amiloride, and you pick a box of amiloride and read out the script that says amlodipine, you'll hear yourself saying "amlodipine" and notice the discrepancy... Sounds daft, I know, but it works!!!
