I had to leave my birth control pills in a hot car trunk for around 8 or 9 hours. Are the pills still effective or did they go bad in the heat?

I believe pills are suppose to be stored at room temperature. You should check the pamphlet that came with the pills and talk to your doctor of phamarcist.

Don't worry I had this same thing happen to me and I called the pharmacist he said not to worry and just keep taking them.
