I know Zantac is safe to take- what about Pepcid?

I am starting to see that I am going to have to start taking a daily acid reducer because all of a sudden, out of the blue, the heartburn and acid issues have hit full force.
Just drinking water in the morning gives me acid!

Can we take a daily Pepcid pill?
Or should I stick to Zantac?

My next appt isn't for 2 weeks and I'm dying here!
