Patients who require syringes for self injection (think insulin, B12 etc.) can acquire them from most pharmacies. Because the pharmacists want to ensure that the syringes are not being used for illegal drugs, they often may request to see a prescription from a doctor/ND for the medication to be injected or simply ask you straight out to know what you want to use it for. Syringes in Canada range from 20 cents to 1 dollar a syringe.
