My cat is on 2 units of lantus twice daily. His BGLs drop to 70 and then get to Hi before his next dose. He's been like that for a while now so I'm thinking about reducing his does to 1.5 units. Unfortunately I can't find the 30 unit syringe with half markings and I've looked everywhere. I also cannot order one online because I live in Egypt and that would be extremely expensive when changing currencies. The only available syringe is the 50 Unit BD syringe with a whole unit increments. I know it's not recommended, but can I dilute Lantus before injection so I could manipulate the dose? Or should I just estimate the half unit and pull the plunger between the two lines as best I could?
