… for someone who is needle phobic.

I have always been pretty needle phobic, fainted for holiday immunisations and jags during pregnancy. I nearly fainted when I took my first dose of mounjaro 4 months ago but have managed this since by doing the jab at bedtime and then just lying down straight away and going to sleep. I imagine repeated exposure to the process is helping a bit too.

I decided not to do the bonus dose as I didn’t want to be messing around over twisting pens to potentially break them and was nervous about using a regular needle and syringe. However, the price increase is not going to be sustainable for me long term, so I’m keen to get the bonus dose from my remaining pens.

Long story to get to my actual questions 😂 You can see I’m overthinking this!

Which syringes and needles should I buy? I do not really want to inject myself with the same needle I’m extracting with, that makes me feel weird. I would like to inject myself with a small/fine a needle as possible, the one on the pen is fine but I don’t really want to go bigger, I’m not sure I’ll manage it.

Would different needle sizes for extracting and injecting be beneficial?

Is there a chance of going too deep when injecting from a syringe? Or is that stupid?

A step by step guide would also be appreciated! I’m a capable person but this is well and truly out of my comfort zone due to my phobia, so I think an idiot’s guide would be useful. Thanks.

You can buy luer lock syringes which are syringes with a twist on / twist off needle. You can then buy longer / bigger gauge needles to extract with and then take this needle off and put a finer one on to inject with.

For example:

1ml Unifix Luer Lock Syringe – UKMEDI 1ml syringe
27g Grey 6mm Meso-relle Needle | UKMEDI Quality needle to extract
32g Pink 4mm Meso-relle Needle | UKMEDI needle to inject

The needle for injecting is the same length as the ones that come with the MJ pen. No chance of going too deep.

Hope this helps x

Do we use all of the remaining medication or measure it? Sorry if that’s a stupid question!

There is usually more than a normal dose in volume left. So measure 0.6ml (60 units on the 1ml syringes) for the exact same dose as the rest of pen, or if you get more and want to use it as a step up then calculate eg 0.75/0.6 x 5 =6.25mg (volume extracted/0.6 x pen strength )

This is exactly what I have just ordered before seeing this post, so very pleased I seem to be on the right track! Thanks @TheNinthLockUnlocked!

@periglpfan thank you 😀

Surely they’ll soon stop having the fifth dose in the pens. I’ve thought that even before this price hike emergency. They won’t want to keep giving extra surely

Definitely a possibility. Just going to try to get what I can before the loophole closes!

I fully expect this too, they needed time to manufacture new style of pen but expect that’s been in the works.

I can’t see why you would need separate needles for drawing up and injecting . Just buy some insulin needles from Amazon and draw up the bonus dose and inject it from the same needle/syringe . If you were having the dose administered by a nurse she wouldn’t change needles as it hasn’t been used before.
