My insulin pen would not pass the flow check

I was getting ready for an injection and noticed that no insulin was coming out during the flow check.

At first I was not sure whether the pen was faulty, the needle was blocked, or I was doing something incorrectly. I do not want to waste insulin, but I also do not want to inject without knowing the pen is working properly.

For people who have faced this, what steps did you take when the pen jammed or no insulin came out during the flow check?

I had this happen once and the first thing I checked was whether the needle was attached properly. I realized the issue was with the needle, not the pen itself.

Same thing happened to me. I assumed the whole pen had failed, but replacing the needle solved it.

I learned that the flow check is an important step because it confirms insulin is able to move through the needle before the actual dose. Skipping it can create uncertainty.

I would check the instructions for the specific pen model because different pens can have different steps. If insulin still does not appear after following the instructions, it may need further attention.

Good point. I used to assume all insulin pens worked exactly the same way.

The first time it happened I was worried I had done something wrong. Now I keep spare needles available so I can quickly check whether that is the problem.

I also check that the pen has been stored correctly and that there are no obvious issues with the device. Storage and handling can matter for insulin products.

I think the main thing is not to force the pen or guess the dose. If something is not working as expected, it is better to troubleshoot carefully or contact the healthcare team or manufacturer.

This is what I was unsure about. I did not know whether to keep trying with the same pen or stop and check what was wrong first.

I keep the pen instructions nearby because small details are easy to forget. It helped me avoid panicking when something unusual happened.

A pharmacist showed me the technique again when I had trouble. Sometimes a quick review of the steps solves the issue.
