The most difficult pharmacy abbreviations to remember are the eyes and ears. They are very easy to mix up, especially because they seem to make no sense.
Try this: When you see the O, think of an EYE which is round. For the A, remember it as "Audio" which is heard through your EARS. For S, think of "South" and Left handed boxers being dubbed southpaw. When you see U, imagine it as a face, needing both eyes or ears.
