Does dr pepper have caffeine in it?

Unlike Coca-Cola and Pepsi, Dr Pepper is not marketed as a cola. Dr Pepper's flavor is allegedly derived from a mixture of soda fountain flavors popular when the drink was first devised. A partial list of these flavors can be seen at the bottling plant in Dublin, Texas, although the formula itself (with its twenty-three ingredients) is a closely guarded secret. Contrary to a popular urban legend, Dr Pepper does not and never has contained prune juice. In Texas, Dr Pepper is extremely competitive in the soft drink market, regularly outselling Pepsi and Coca-Cola.
