Can You Use The Same Needle Twice?

[Irish Lad 34]

I have Viridal Duo 40mcg shots. Each cartridge comes with a needle. You take the needle out of its case and pop it onto the cartridge when you want to inject.

I went out drinking a few weeks ago with 2 cartridges and 2 needles in my back pocket. But it seems I lost 1 of the needles.

So - can I use the same needle twice?

Like, if I use a needle for 1 cartridge this weekend then remove it, wash it thoroughly and put it back in its box - will I be able to then use it on another cartridge in like a week?

I guess it comes down to two things :

1. Hygiene and safety - If it's only you using the needle the risks of getting a disease etc are basically 0. However, the needle can get contaminated by air, microbes etc when being "unpacked" from it's original package. Probably a very low chance of getting an infection or anything, but at least clean it properly with an alcohol swab before re-using.

2. Confort - the needles are extremely sharp originally, to minimise pain. So much so that a single use might drastically blunt them, compared to the first use. Thus, if you re-use the same needle, prepare for it to hurt more.
