Storage basics
keep it in the fridge if instructed, not the freezer
keep it away from the fridge’s coldest spots, where it could freeze
protect it from light if instructed
never leave it in a hot car
write the date you first opened it on the vial
Before each dose
check the date
look at the liquid: it should look as your pharmacy described. Compounded products don’t have one standard appearance, so your pharmacy’s own description is the reference — call them if it doesn’t match
use a new syringe every time
clean the vial top as instructed
When to call your pharmacy
the vial froze or got hot
the liquid looks cloudy, discolored or has particles (unless expected)
the strength on a refill is different
you’re unsure how many units to draw
A real-life example
Becca, 37, noticed her new vial said 5 mg/mL instead of her usual 2.5 mg/mL. She called the pharmacy before injecting. They confirmed her dose was now half as many units.
Common questions
How long does compounded semaglutide last in the fridge?
It depends on your pharmacy’s beyond-use date. Follow their label.
Can I travel with a compounded vial?
Ask your pharmacy how long it can be out of the fridge, and pack it in an insulated case.
What if my vial froze?
Don’t use it. Call your pharmacy.
