A member asked:
I left my birth control in my car for a week when the temps severely dropped (-5) for 2 days. would the effectiveness of the pills go down because of the cold?

The manufacturer label typically has oral contraceptive pills storage requirements to be at controlled room temperature as per USP. There’s no mention of effectiveness outside this range but one could assume that it would be less effective
