how to use this page
This is the decoder ring for a typical glutathione injection instruction: what "subcutaneous" means, how units and ml relate, how often it's taken, and the 30-day vial rule.
Key Takeaway
what "subcutaneous" means
Glutathione is commonly given subcutaneously, into the soft, fatty layer just under the skin, not into muscle. The usual spots are the belly (a couple inches from the navel), the front of the thigh, or the back of the upper arm. Rotating where you inject each time keeps any one area from getting sore.
reading the dose: units and ml are the same thing
Glutathione instructions usually list the dose two ways at once, for example, a volume in ml plus a number of "units" on the syringe. Those are the same amount: on an insulin syringe, you draw up to the line your instructions name: the "units" are the marks printed on the syringe and the "ml" is the actual volume.
Your real numbers are on your prescription. This is only how to read the notation.
how often
Glutathione is commonly taken once or twice a week. Your instructions tell you how often. Follow the schedule on your prescription.
the 30-day vial rule
Once you first puncture a vial with a needle, it's good for 30 days, then you discard it and open a fresh one, even if there's still plenty of liquid left.
- The moment you first use a vial, write that date on it.
- Use that vial until the 30-day mark, then throw it out and start the next one.
The 30 days is about keeping the medication sterile after the seal is broken, not about the vial running empty.
why you may have received more than one vial
If your glutathione came as more than one vial, it's usually the 30-day rule at work, not because you need that much at once. You move to a fresh vial roughly once a month, and the set is meant to carry you through to your next refill. Open one at a time, discard at 30 days no matter how full it looks, and work through them in order.

Frequently asked questions
It says a volume in ml and also units, which do I use?
Both: they're the same amount written two ways. On an insulin syringe, draw up to the line your instructions name.
How often do I take it?
It depends on your form and prescription: the injection is commonly once or twice a week. Follow the frequency on your instructions, and ask your provider if you're unsure.
The vial still looks full at 30 days, do I really discard it?
Yes. The 30-day limit is about keeping the medication sterile once the vial has been punctured, not about how much is left inside.
