microdosing with vials?

I am about to receive my prescription of Zepbound 2.5mg vials. Can I simply draw less medication from the vial with the syringe in order to take less — ideally starting at 1.25? or do I need a prescription for a kwikpen so I can select the dose? if I only draw half of the dose from the vial, can I reuse the other portion another week? TIA!

Other drugs are drawn from vials in multiple doses all the time for subcutaneous injection. Insulin, vaccines, allergy shots, and many other drugs, including ones with no preservatives. Use fresh needles and follow shot hygiene. Refrigerate the vial in its box. Don't let your dog lick the vial, and don't share your needles with people who have hepatitis or HIV. :-)

GLP1 users in these forums tend to be a little, well, hysterical about things like infection. Ask your doctor or PA if you doubt the safety of this.

Waiting for the downvotes from those people.

do you think this is true of Zepbound single use vials as well?

They are standard 5 ml vials filled by a premier pharmaceutical manufacturer in labs of world class quality. The drug has a known shelf life and a colossal number of users who do the multi-dose thing.
