I agree that Carafate suspension (liquid) is the best option. Call your pharmacist and ask about temperature requirements and what they recommend. If you're traveling, you can also ask your pharmacist or a smaller bottle that is easier to carry with you.
I found this information online:
Stability and Storage Recommendations:
® SUSPENSION PLUS should be stored at room temperature between 15
and 30°C. Avoid freezing.
(Here's the conversion: 30 C ..........86.0 F)
This is a Canadian generic (an I'm sure much cheaper) version of Carafate suspension. While I know that it's not "Carafate" specifically, Sulcrafate is the generic term for Carafate, so I expect that this is exactly the same thing (probably tastes different). FYI here's a link to the PDF doc I got the information from. It also has lots of other details about it as well:
