So, once and for all: does Prozac contain fluoride? The simple answer is yes. Prozac not only contains fluoride, Prozac is fluoride.
Prozac is the brand name for a chemical compound called fluoxetine hydrochloride. Fluoxetine is made up of five different elements (C17H18F3NO). Fluorine is one of those elements (F3).
Fluorine is a gas and never occurs in a free state in nature.
Fluorine exists only in combination with other elements as fluoride compounds. Both organic and inorganic compounds containing the element fluorine (F) are considered fluorides. This means fluoxetine is a fluoride. Therefore, we could say Prozac is fluoride. Fluoxetine is the only ingredient in Prozac and fluoxetine is a fluoride.*
