Medication losing potency/degrading during international transport?

Has anyone experienced this problem? Something to do with being stored in the cargo hold of an aeroplane and being exposed to higher temperatures. We've got a batch that simply does not work and this looks like the best reason, <online pharmacy> have been great and are trying to help, I just wondered if this was a thing? I know that Mary Shomon has mentioned it in her blog.

I hope everyone is as well as can be expected.

Last year I went to South Africa. As i take my ndt in a split dose, i had no option but to carry it with me in boiling temperatures (39 degrees C) every day.

I was very concerned about what the heat was doing to the tabs, but i can honestly say I felt no different symptom wise. I use Thyroid S


My Armour Thyroid patient leaflet said to store between 15- 30 degrees centigrade

( 59 and 86 farenheit )...... Would an aircraft hold really go above 86 degrees ????

Mine too came from USA


Don't know about medications, as we alwasy carry them on us, but my son's glucose monitor would not work after my husband put it in the hold with luggage.


My tabs are not supposed to be stored above 25 degrees and they were in 39 - 40 degrees C daily
