IrCOm looking for a way of keeping my eye drops cool, i.e. < 25c, when en route to/from a warm destination abroad traveling by air. A lot of the cooling devices IrCOve seen online are for insulin containers but I need to carry a supply of Tafluprost and a couple of bottles of Brinzolamide. I guess thererCOs potentially a 48 hour period where these items will not be refrigerated. The only really critical item is Tafluprost but it seems to make sense to include the other items too. Any advice from someone in a similar situation would be most welcome. TIA.

Chill the medicine and chill your clothes and wrap the medicine in the
clothes in your suitcase. The insulation properties of the clothing
will see a very slowed-down warming - maybe none at all if they are
flying in your hold luggage in an unheated freight compartment. That
should get you to your destination.

I have no experience of medicines but I have regularly transported low
melting point chocolate truffles to blisteringly hot destinations this
way and the goods have arrived unharmed.

Just use an insulated cooler bag with one of those
frozen packs wrapped in an old flannel or something.

Latanoprost and Cosopt (which are v similar) must not
be refridgerated, just kept at normal temps below 25C.
You should be ok inside the cabin.

If you have a supply of single-use droppers then its
less of a worry than having to use a 28-day bottle

One simple solution that I've come across is a sort of wallet inside
another wallet. The idea is that you soak the outer one in cold water
and put your eye drops in the inner wallet. The outer one then provides evaporative cooling. The effect won't, I guess, be all that great if
high temperatures are accompanied by high relative humidity. You can
buy this cooling wallet from Glaucoma UK and no doubt other charities or medical suppliers. I have tried one and it works to some extent for a shortish period, but doesn't provide all that much cooling and would
certainly not last as long as 48 hours. So I can't really recommend it,
but YMMV.

Vacuum flask, with something else insulating to fill in the gap? Maybe even spray expanding foam into it, poking something in that you remove when it
has set to make a space for the bottles. Pre-chill everything before you leave.

You would likely need to remove them for security, but you could put them in the X-ray baggy with an ice pack and then return them to the flask.

(If multiple flights are involved you might need to acquire some icecream in the lounge so they survive several security checkpoints)

Actually, thinking about this it's a tradeoff between the insulation value
of the 'stuff' inside, and the amount of 'cold' that's stored. Insulation
will stop the cold leaking out, but it isn't very good as a reservoir.

In that case, filling the thermos flask full of sand and thoroughly chilling the whole thing (with the lid off) may provide a better reservoir of 'cold', even if that cold leaks out more rapidly (which is mostly via the neck, something expanding foam won't improve greatly).

I assuming freezing it is 'too cold' for the drops, else frozen sand would
act as a good reservoir. Chilled sand will still help though, and be better than a liquid which can convect.

Read the leaflet that comes with your eye drops. Most will
say 'Do NOT refridgerate or store above 25C'. All you need
to do is keep them in some sort of cooler bag to avoid
getting too warm. Inside the plane it will be air-conditioned
as will most airline check-ins and holding areas.

I've ordered a large Frio bag now so let's hope it lives up to to its claims. Many thanks to GB and the others who offered advice.

Are these a prescription item? Could you just buy a new bottle on
arrival (assuming the hotel has a fridge)?

I used a Frio pack to keep my diabetic injection pen cool. Kept it below
25C even in places that were up in the mid to high 30s. Injection drugs
now available in tablets so I don't have to manage pens, needles, sharps
boxes at present.
