Abbreviations Used in Prescription Writing

  

 

 

 

 

.

...

A warning; and the strange case of S.I.D.: Although prescription abbreviations are used throughout this reference and they are fairly well recognized, they do increase the potential for mistakes to occur. When writing a prescription, this author recommends writing out the directions in plain English and avoiding the use of abbreviations entirely. If abbreviations are to be used, definitely avoid q.d., q.o.d., and s.i.d. because they can be easily confused with other abbreviations.

            S.I.D. is virtually unknown to health professionals outside of veterinary medicine and the vast majority of pharmacists have never seen it used. S.I.D. should be eliminated from all veterinary usage.
