storing Hydroxocobalamin ampoules

[bambuko]

Just received my first order of 100 ampoules from Versandapo (easy and painless process).

Understand one is supposed to store them below 25 deg C.

How do you (experienced self injecters) keep your ampoules safely?

Today temp inside my house has reached 25 deg C ...

and it is only going to get warmer

I asked the same.

In the dark.

In a cool place in a drawer?

I've put mine under the stairs as cool there .

Or in the door of the fridge in the box

they can be stored in the fridge in hot weather but do warm them up - eg in the palm of your hand - before you inject

thank you guys,

I have managed to liberate some space in the fridge

I was asking for advice, because whilst it says store below 25 deg C it doesn't say whether it is OK to keep in the fridge (which I guess will be something between 2 deg C and 5 deg C)

I keep mine on a shelf in my bedroom. It's cool and dark. Yes, sometimes it gets above 25 C for a few hours, but I don't worry about it.

When they say it should be stored below 25 C, they don't mean that it instantly goes off at a higher temperature. It means it will go off slightly faster.

A rule of thumb we chemists use is that a reaction will go twice as fast when the temperature is increased by 10 C. So if the B12 lasts two years at 25 C it will only last one year at 35 C (that's 35 C every minute of every day of that year). The difference between 25 C and 28 C (for a few hours over 30 days) will only be a week or so off the nominal shelf life (which is a hugely under optimistic figure).

My B12 might go in the fridge if we have temperatures over 30 C for a week.

that's interesting - thank you!

so perhaps I should not be so paranoid

having said so, from what you are telling me - there is no harm in keeping it in the fridge?

Last summer when it got very warm I kept mine on the floor of my cupboard under the stairs. I had a thermometer there and it didn't exceed 25 degrees even on the hottest days.
