Is 3 hours of heat exposure enough time to destroy NDT medication's potency? Earlier this year, i think in May, two bottles of my NDT meds were delivered on a particularly hot day, something like 90-95 degrees as I recall. They were left there in the heat in my mailbox, though my mailbox is shaded by trees, for 3-4 hours. I am running out of my supply and wondering if these are ok for me to take or if they were likely compromised by the hot weather.
Do you think my NDT meds ruined by the heat? - Thyroid UK
According to verywellhealth web site levothyroxine, liothyronine and NDT should not be stored above 86 deg F as they can degrade. They should be kept out of light (hence dark glass bottle my NDT comes in) and away from moisture too. Hope that helps.
You could put a thermometer with max and min recording in your cupboard if you get those temps again and see what it logs if it is below 86 you ought to be ok although it will not be identical conditions of course. I get the impression it is the moisture and condensation of the fridge getting into the NDT rather than the temperature per say that makes fridge storage a bad idea I have done it for 5 years and I seem to be ok on it!
