Does anyone know if there are 1/4 unit marked ? My eyesight isn't that good and the 1/2 unit ones are small. Sometimes I need to inject 1/2 unit for corrections.
There are no 1/4 unit syringes. For micro dosing the only options are diluting insulin and a pump.
Another technique you can use is to bolus for 1/2 unit and eat couple of grams of glucose.
