Medications other than epidural?

I'm realllly far off from giving birth but I figured that I may as well start looking into things so that I can be better prepared later on. Epidurals just kind of freak me out in general and I've never known why. I know they work wonders and I'm not going to definitely say no to it but I also want to explore other options too before I say yes to an epidural right away. What all did you have and how well did it work? Especially those of you with low pain tolerance like me? Side note, I live in the US. I know some countries sometimes use medication that may not be used here for labor.
