I'm well into SI (just did my second!) and using the same needle to draw the liquid out of the ampoule as to inject, which doesn't seem to be a problem except that I can't get it all out of the ampoule no matter how I try. Tonight I ended up injecting just over 1/2ml. I've tried pushing air into the ampoule, tipping it upside down, on its side, repeatedly trying to draw more up. Help! What am I doing wrong?
Self-injecting question: I'm well into... - Pernicious Anaemi...
There shouldn't be a need for a special needle as such. I use a 21g (green) to draw up (wider gauge) then a 23g (light blue) to inject. Never a problem getting pretty much all of it out. I also use 2.5ml barrels. I get my needles etc at local needle exchange. I've never used a 26g but am guessing it's too fine a needle for drawing maybe??
I was taught to use the 21g (green) needle to draw up and the 23g (blue) to inject. Tilt the ampoule with the top snapped off slightly, put the tip of the needle right down into the lowest part of the ampoule and draw up the serum.
Change to the thinner needle and expel the air. Then inject.
The reason for using the two needles, and they could both be the fine ones if you were so ammind, is to make sure the tip is a sharp as it can be, without a turning over of the tip which can happen when you push it down to the bottom of the ampoule. You would know about it if you were withdrawing a hooked needle point.
Needles are £2.37/100 plus VAT and p&p so not worth taking the risk.
I draw out liquid with a green needle - but I was shown how to first pull the plunger back a little way on the syringe before removing the liquid, so there's a gap at the top between the drawn out liquid and the flat part of the plunger. Then I change needles to a tiny yellow one for subcutaneous injection. Plunge syringe gently to get liquid to end of needle. Because there's a small gap between plunger and liquid, you'll find all of the liquid goes into the needle when you start to inject. Obviously stop when it's all gone, so you're not injecting the tiny bit of air. It's this little bit of air that pushes all the liquid out, meaning you'll get the full benefit of the entire 1ml instead of it being short. This technique should work too if you're only using one needle, I imagine. Good luck!
Hi, As far as I understand, IM injections are absorbed a bit more quickly than S/C.
I started by IM injections but now I do S/c with an orange (25G) needle, and inject into my abdomen. I find it easier, to be honest, than in leg. Self-injecting into arm is quite hard although, I suppose it's possible - I wouldn't be able to do it into arm.
I've read various peoples' opinions about which is best, but common consensus seems to be that it really doesn't matter which you do - whatever you feel most comfortable with. Some people say IM gets into your system quicker, but then you'll only use however much B12 you need anyway, and the rest will be passed out of your body, so it doesn't really matter. I can't do IM either - feel much happier injecting into the flesh of my stomach and it works well for me!
