1. aspirin: pp od x3d
2. aziwok: ac od x7d

what is the meaning of above example? it is written in the prescription.

I'm not an expert. Here's what I've found:

pp od x3d = post prandium (= after meal), once a day for three days

(for pp see http://dictionary.reference.com/browse/PP )

ac od x7d = ante cibum (= before meal), once a day for seven days

(for ac see http://dictionary.reference.com/browse/ac )
