Hello everyone!!
I have read on internet that after opening lantus pen use it within 28 days.. Ok but the problem is that my son's dose is very low about 3 to 4 units so I can use it for almost two months..
Now I m confused what should I do?? I mean should I stop using the pen at 28th day and open a new one or I can use it longer.


Thank you!!!
 
Evening. Yes after a month you need to change to a new cartridge. As it will stop working effectively. Seems waste full but a necessary change
