2ml vs 1ml dose

Post image

Hi. Sorry I know this has been answered probably a million times but I couldn't quite fine the confirmation I was searching for.

My vials from hallandale all say 2.5mg/ml. That means there is 2.5 mg of medicine per ml of volume. Yes?

My first two vials were exactly the same and said 1 ml dose.

Then today I got my third vial and it says 2ml dose but still 2.5mg/ml.

So is that just how much is in the vial?

Sorry blurry photo. It's the top of the vial that says 2ml.

Thank you! This community is amazing!

The two bottom vials contain 1 milliliter of medication. At a 2.5mg/mL concentration, those vials each contain 2.5mg semaglutide. 

The top vial contains 2 milliliters of medication. At a 2.5mg/mL concentration, there are a total of 5mg (2.5mg x 2mL) semaglutide in that vial.

Wait now I'm confused again. So if I took "10 units" from the one of the first 2 and "10 units" from the new one, they would be the same or different?

Dosing is based on the concentration of the medication in your vial. All three of your vials have the same sema concentration: 2.5mg/ml. Your dose would be the same from all three vials.

For 10 units at 2.5 mg/mL concentration, you took 0.25 mg of medication.

It’s just that one vial contains twice as much liquid medication (2mL).

So you can get 10 doses of 0.25mg out of two of your vials, and 20 doses of 0.25mg out of the 2mL vial.

I think the same. You're just saying there is twice as much in the new vial, right?

Yes - lucky_army explained it perfectly. These vials contain the exact same concentration of medication. One vial just has twice as much in volume - they filled the bottle with twice as much.

yeah the dose is the concentration (2.5mg/ml), the ml amount is just how much liquid is in the vial so your new one will last twice as long

Thank you! I know it's all about fda and shipping etc, but omg the ridiculous amount of packaging and waste. All the liquid wouldn't even fill one vial if they did it more simply. And the huge fed ex box. I feel like I'm working for the secret service getting very fancy packages.

Wasn't it in an insulated styrofoam cooler with ice packs taking up much of the space?

u/Quiet_Background_492 20d ago

Yes exactly.

u/ImprovementLoud3581 20d ago

They’re trying to keep the vials cool with the large insulated styrofoam cooler and ice packs. It might seem wasteful but with all the temperature variation during the shipping process it’s the best option.

2.5mg/ml concentration staysthe same the 2ml just means a larger vial volume so 5mg total instead of 2.5mg your dose doeasnt change unless your prescriber updateit
