A 34-year-old female asked:

I've read conflicting information. does the fluorine in prozac (fluoxetine) break down into fluoride at all and if it does, how and what happens? thank you.

Prozac (fluoxetine) & Fluorine: Prozac (fluoxetine) does contain a fluorine moiety on its molecule. But the organic carbon-fluorine bond is very strong -- meaning it's very unlikely to break down into Fluoride atoms. Most historical cases of Fluoride toxicity have happened with insecticides & rodenticides that contain inorganic fluoride. It's not a good idea to swallow toothpaste either, because of inorganic fluoride.

No: Prozac's generic name is fluoxetine which sounds a little like flourine. To my knowledge, Prozac does not contain flourine.

Prozac does contain a fluoride group on its molecule, but its bonds are very strong and do not break down like an inorganic bond would. Please see this link for a diagram of it: http://tinyurl.com/lhr9edj
