Question: what is the difference between aspirin ibuprofen and acetaminophen?
Answer: There are basically two types of OTC pain relievers. Some contain acetaminophen, which is processed in the liver. Others contain non-steroidal anti-inflammatory drugs (NSAIDs), which are processed elsewhere. Examples of OTC NSAIDs are aspirin, ibuprofen (Advil) and naproxen sodium (Aleve).
