Crystals can be dissolved and reincorporated, but it’s a potential cause for irritation if they aren’t fully dissolved. This goes for both sealed and unsealed vials.
Additionally: before drawing from a vial, partially fill your syringe with air so that when you draw fluid from the vial you replace it with an equivalent volume of air. This simple step prevents a vacuum from forming over time inside the vial which can make drawing sigificantly more difficult.
+Dead space refers to the amount of fluid that is wasted when performing an injection. This is fluid that is trapped in the syringe or in the needle. With a standard Luer lock needle/syringe this can be up to 0.1mL, whereas in an insulin needle can be as low as 0.003mL. Reducing dead space is recommended for economic reasons because it adds up to a lot of wasted estrogen. This calculator can be useful for estimating how much estrogen is wasted depending on the supplies used.
One thing to note if you are swapping needles for drawing and injecting, then you should pull the plunger back slightly prior to taking off the drawing needle so that the fluid inside the drawing needle is not wasted. It is very minor, but it can make a difference. Note as well that syringe markings already account for dead space, so you should not manually add more to your injection. See Question 7.7 for another possible strategy if concerned about high dead space.
