Objectives: To determine the pattern of unnecessary injection prescription practice and to evaluate the effect of health education in improving rational injection prescription among health workers in Katsina State. Methodology: A quasi experimental design was used to study 275 primary health care workers among the study group and control groups with 222 prescription slips selected randomly on exit from consultation rooms.

Most of the health workers practice prescription, the mean injection prescribed 49.0±38.7 pre intervention and 24.3±24.3 post intervention among the study group. Poly pharmacy with an average of 6.0 drugs pre intervention to 5.69 drugs post intervention remained among the workers. The mean injection prescribed reduced from 2.009±1.6 to 1.792±1.6 post intervention (p=0.001),most of the prescriptions issued by the study participants have significantly improved in writing full name of drugs, dose of medication, dose interval and legible hand writing (p<0.05). Use of generic name has improved to 52.3% post intervention and prescriber-patient communication also improved averagely in explaining to patient why oral drugs was better than injection and why injection was prescribed has improved to  84.4% and 89.6% post intervention significantly(p<0.05).
