Honestly speaking I am not familiar with sig codes and never tried to understand it. A new capability in the computational knowledge engine Wolfram Alpha inspired me to try to learn what it really is. Sig codes are the abbreviations doctors commonly used in their prescriptions. Yep! It is the abbreviations of some Latin words. Your pharmacist can easily understand the sig codes. Now you can also understand what are those abbreviations in your prescription. Search on Wolfram Alpha to learn sig codes in your medical prescription.
