I’ve bought a bottle of liquid Regaine and read the booklet, which said that the max. temp at which I can keep it is 25 C degrees. I figured that I should put it in the fridge then…so it spent about 14 hours in the fridge, when I googled for a booklet in English and they said that it has to be kept at 20-25 C (some say 15-25). I have no idea how cold the inside of a fridge is, but i guess its below 15 C…so, have I totaled 50 dollars?
I doubt you harmed the medication effectiveness, but I would follow the instructions on the bottle and not different language instructions you’ve found on the web (there might be slightly different formulations or packaging). My gut tells me you’re worrying about this too much.
The temperature warnings might just be safety notices so you’re not shocked if the medication’s container explodes under pressure created by fluctuating temperatures, though it also will likely contain some wiggle room on the exact temperature (which is why you’ve seen the range move so drastically). If you don’t know how cold it is in the refrigerator, get a thermometer so you don’t have to worry about this anymore.
