Reconstituting with insulin needle

Summary

Can you reconstitute tirzepatide using insulin needles or syringes?

Participants confirm insulin syringes work fine for reconstitution and may even offer better precision with less stopper damage. One suggestion is to use two syringes, removing the plunger from one to vent the vial. Another notes the second plunger can stay in place and push out automatically. Everyone agrees to watch the unit markings instead of milliliters.

Hi everyone, apologies if this seems like a dumb question. I bought all the supplies to try tirzepatide but missed getting reconstitution needles. Can I use insulin needles for that, or is there a problem with it?

Yeah, go ahead and use it. It's basically just a syringe with a needle attached. Just watch the measurements because they're in units instead of milliliters.

Yes, your insulin syringe should work fine for that.

Actually, it might be preferable because it allows for more precision and doesn't damage the vial's stopper as much. Though we don't really know the exact amount in the vial anyway, it's still a better method.

Try using two of them. Remove the plunger from one to allow air to escape from the vial.

Interesting, you could probably keep the plunger in the second syringe so it gets pushed out on its own, reducing the risk of anything dropping into it.

That's a good suggestion, thanks!

Thanks! And yeah, noting the difference between milliliters and units is helpful.
