Acetaminophen only contains acetaminophen, but some medications contain mixtures of acetaminophen, caffine, and possibly other things. Read the label to know for sure.
No, flexeril is a muscle relaxant. The drug name is cyclobenzaprine. Ibuprofen is a non-steroidal anti-inflammatory pain medicine. You can safely take a pain reliever and a muscle relaxant together....
