Needle sizes for sub cutaneous injecting.

Hi all, I apologise in advance, as this has probably been asked many times before. Can anyone recommend the best needle size for sub cutaneous injecting? And how far apart should injections be? I know everyone is different so just an average would be great. Thank you in advance

Most people use orange 25G 1" needles - medisave.co.uk/b-d-microlan...

The correct frequency of injection is - often enough to keep symptoms at bay. That can vary from once a day to thrice a year. The only way to tell is to try it.

Just a note for anyone doing sub q that apparently 1 inch is too big. Suggestions are 27-30g used. 5/8 or 1/2".

Alternatively, you might obtain U-100 Insulin syringes eg BD Micro-Fine Plus (manufacturer Becton, Dickinson, France and USA). They hold 1mL and have a needle length of 8mm.

Hi Dollery, thanks for your answer.

Can these needles be used to extract the B12 from the ampoules as well as injecting? Thanks

Good question! You can deal with the 1mL ampoules with a little dexterity.

With part of my hand touching the table, to steady it, I lower the needle fully into the upright vial (on the table), Then, gently holding the vial against a side of the plastic base of the syringe, with a finger, I lift the vial as one with the syringe - same hand holing both. Now (keeping in place the finger holding the two together, of course), with the other hand, I begin to draw up the contents, gradually tilting the whole, such that the vial’s reducing contents continue to be accessible to the needle tip - eventually I have the vial horizontal. I’m content to recover 80-90 %.

You could try it first with juice in a used vial. If you do, let et me know how you get on.

Best wishes.
