what is the difference between pepcid and ranitidine?
Pepcid (Famotidine) works well for heartburn but may not last as long or start working as quickly as other antacids. Zantac 75 (ranitidine) works well to relieve heartburn symtoms and is quite tolerable. You can take it in combination with a quick-acting antacid (like Maalox or Tums) if you need relief right away.
