Why is ibuprofen almost always burnt-red? Why is acetaminophen either white or red/white?
It doesn’t seem to matter who the manufacturer is – Ibuprofen almost always is brick red. Acetominophen is usually white (or sometimes red/white capsules although I have seen red-white-light blue).
Either the same company is manufacturing for everyone or there is some standard about what color OTC meds have to be.
Why is this? Who sets the standard?
