Bought some Motrin Pain and Migraine Reliever (400mg capsules of Ibuprofen) when I was at the grocery store. Unfortunately I didn't notice they were in a bag with some of my freezer goods and I proceeded to put them in the freezer (in the bag).

Went to get something else out of the bag 48 hrs later and found the bottle.

It says to store them between 15 and 25 degrees Celsius and I'm wondering if there would be any adverse effects from this? Obviously it isn't like heat and they aren't destroyed but do I have to throw out the bottle now? Will they be less effective? Will it change anything at all?

Thank you for your time!
