Hi Taz2,
I live in Queensland Australia, and have never ever put medication like Panadol in the fridge. As you can imagine most of the year is above 25 degrees and we have high humidity too.
I don’t understand UK doctors scaring their patients about there medication not working.
I hate to think how hot my medication can get as I always carry paracetamol in my handbag.
I have never taken medication in my life including vagina atrophy medication, and thought why isn’t it working, oh hang on it’s summer. I’ve also never heard or read anything about is your medication to hot and how you should store it with Australian media.
And I’ve only bought two medication were the chemist has told me to get it in the fridge as soon as possible. They were a probiotic and suppositories for my butt.
So I wouldn’t worry too much, but if you feel better sticking it in the fridge then do so.
