Can you buy additive free ibuprofen

i don't know yet, but i'm looking for some, and additive free acetaminophen too. as long as they are white, the adult tablet's ingredients don't look too bad. i'm specifically looking for kid's versions that are either liquid or tablets. i may have to get an rx from our doctor and have a compounding pharmacy make some for us. could cost more than $50 dollars though. i wish companies would realize that people are seeking natural products and accommodate us. we'll buy them!
