Question
Hello, I would like to ask about insulin: is it permitted to change the needle in the pen and adjust the dosage on a holiday?
Answer
Hello,
If it is possible to prepare from the eve of the holiday, it should be done that way.
If this is not possible, it is permitted to do so to maintain sugar levels, which is a concern of danger.
Also, what needs to be done on the holiday and Shabbat should be done with a change, which reduces the prohibition to a rabbinic level and not a Torah level. However, what cannot be done with a change is permitted to be done in the usual manner.
