Do any prescription drugs also contain non-prescription ingredients?

[KittyKatt]

Are any of the ingredients in prescription diet pills also available in non-prescription diet pills? Like, is there a pill that has a strong ingredient in it that makes it prescription strength, but that also contains something else that is effective that isn't as strong so non-prescription pills have it, too?

[MeSarah]

That's a really good question. I don't think so. I say this only because there would be lots of OTC diet pills on the market claiming to work just as good as a prescription drug because they contain the same nonprescription ingredient, with the benefit that you don't get all the side effects and blah blah blah. I can't say I know of any herbal or nonprescription ingredient like that.

I also don't think so, because if that were the case, all the OTC companies would be selling the ingredient.

[Whirlybird]

I didn't think of that but ya, you're right if that was the case, every OTC company under the sun would be flaunting it.

The only one I can think of OTC wise is Alli, which contains orlistat, which is also found in Xenical (the prescription version). Is that what you mean?
