What Is Acetaminophen or Ibuprofen?
Acetaminophen and ibuprofen are over-the-counter pain relievers.
Both help reduce pain and fever. However, they work differently inside the body.

Ibuprofen belongs to a group called NSAIDs (nonsteroidal anti-inflammatory drugs). It reduces pain by lowering inflammation.
Although both medicines treat similar symptoms, they are not always interchangeable.
