Injection duration: most pens deliver the dose over several seconds. Holding the button down for the full duration ensures complete delivery. Releasing early can result in underdosing.

Pen dose counters: what a click does and does not guarantee posts 31–60
This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
Worth separating two things that post #29 runs together.
Priming: most pens require priming before the first use (injecting a small amount to fill the needle and line). Not priming can result in no dose being delivered on the first injection.

owen.brady, post #23: Picking up post #20: that is the part I would want checked first. Storage after first use: most pens can be stored at room temperature after first use, even if unrefrigerated, for a limited time (often 28 days). Check your specific pen's labelling. Go to post
post #33 is right about the mechanism and I think understates the practical bit.
Dose counters: pens show the remaining number of doses. When the counter reaches zero, the pen is empty and cannot deliver more. Noting the counter before injection prevents running out unexpectedly.
r.ilunga, post #8: On post #4 — agreed on the reasoning, with one qualification. Two things before anyone answers the substance. First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound. Go to post
Coming back to post #33, because the follow-up matters more than the original answer.
Pen confusion between compounds: if you are using multiple pens or alternating pens, confirming you have the correct pen before injection prevents administration errors. Check the label every time.
mira.patel, post #21: Off-label dosing with a pen: if you want to deliver a dose different from the pen's pre-set steps (e.g., halfway between two step doses), that is off-label use. Some pens allow it; others do not. Confirm before attempting. Go to post
post #37 answers the question as asked. The question underneath it is different.
Needle installation: some pens require a fresh needle for each injection; others have a single needle that stays attached. Check the design of your pen.

This follows post #37 rather than contradicting it.
Reusability: some pens are single-use (throw away after one injection). Others can be reused until empty. Confirm which type you have. Reusing a single-use pen is ineffective because the mechanism does not reset.

Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did and when. The single most useful thing in your own records is not any individual result; it is that they are dated and consecutive.

Worth separating two things that post #44 runs together.
Pen mechanics: most pens are dial-and-inject devices where you dial the dose on the pen and push the button to inject. Understanding your specific pen's mechanism prevents dose errors.

Visibility of the dose: some pens allow you to see the insulin remaining; others do not. Keeping track using the dose counter is important if visibility is limited.
