Did storing tablets at a temperature of 2 degrees in the car for 8 hours affect their effectiveness?

You do not have to worry, the effectiveness of the tablets is preserved.

So those 30 minutes in the car in May when it is warm does not reduce the effectiveness of contraceptive pills? And these somehow 30 minutes in the gallery walking around the shops and somehow a few minutes outside where it was windy also do not reduce the effectiveness of these pills right? And I don't have to worry?

For @Gabriela: The properties of the tablets are preserved. Short-term exposure to a lower/higher than recommended temperature does not affect the effectiveness of the tablets.

The tablets were just bought unused and transported home so they were about 29 minutes in a car where it was warm and outside a few minutes where it was windy and cool.

And what if the tablets I mailam in the purse that was closed I had them in the car about 20 minutes because I transported them home (we have May so it starts to get warm) also a few minutes I was outside with them in my purse and outside it was already cool because the wind was blowing which does not change that it is May or such a situation could obmziyc their effectiveness?

Tak, bez obaw może Pani je stosować. Tabletki przebywając w temperaturze 2 stopni, owinięte w kurtkę, nie stracą swojej skuteczności i działania, tak jak napisałam - producent najpewniej wziął to pod uwagę w procesie tworzenia tabletek. Nie ma Pani powodów do niepokoju.

Czyli bez obaw mogę je stosować ?a co jeśli rzeczywiście by okazało się że były w za niskiej temperaturze,czy wtedy to osłabia w dużym stopniu i h skuteczność?

To tym bardziej - nie ma powodów do obaw. Producent najpewniej przewidział, że zimą tabletki będą transportowane z apteki do domu i będą przebywały przez jakiś czas w niższych niż zalecane temperaturach.

Tabletki były również owinięte w kurtkę i leżały w samochodzie przez te kilka godzin.
