daisylou, how was your injection?

I'm in the Central Valley and agree the heat could destroy your medicine.
I'd considered Tymlos. But was determined to take Forteo. The Amgen rep told me it was safe to leave the opened pen in the refrigerator. Some on this site leave the pens in so that they can take the two or three injections that are usually left after the 30 injections.
You could take the opened pen with you, but there are pen thermoses. https://www.google.com/search?q=amazon+pen+thermoses+for+insulin&oq=amazon+pen+thermoses+for+insulin&gs_lcrp=EgZjaHJvbWUyBggAEEUYOTIGCAEQRRhA0gEJMTM5ODZqMGo3qAIAsAIA&sourceid=chrome&ie=UTF-8
