Those living in warm climate

Protection varies with the med.
It's quite variable........

But it still comes down to age, temp variations, humidity and sunlight.

To be safe take ALL variables into account.

all meds have a life span.
Temp variations can definitely be a factor.....but not always.
Humidity is particularly a problem with pills disintegrating and melding.
and Sunlight is probably the most damaging.

Any dark, dry, air/light proof container stored in a not hot place is the way to go.
