Hi, does one need a prescription to buy insulin syringes (with the half unit markings) in Canada and the UK? And if not, any suggestions on where I can buy them? I live in Mumbai, India and the only insulin syringes we get here are 1ml (100 unit) ones with 2 unit calibrations! I order my syringes from the US - I order them online from ADW Diabetes and get a friend or relative coming from the US to bring them to me. With the covid situation I am trying to see if I can find other sources for syringes.
