A small drop at the needle tip after injection is normal. If the pen is leaking significantly, do not use it. Contact your pharmacy.

Yes, you can let the pen come to room temperature before injecting. This may make the injection more comfortable. Do not use artificial heat (microwave, hot water).

"What if I see air bubbles?"
