Tylenol and Aleve are not the same. Tylenol is the brand name for a non-prescription drug called acetaminophen, and Aleve is the brand name for an over-the-counter drug called naproxen sodium, according to WebMD.
WebMD explains that both of these drugs work to reduce fever, relieve pain and reduce inflammation. Aleve effectively treats headaches, tendonitis, muscle aches, menstrual cramps, dental pain and arthritic joint stiffness. Tylenol works well for the above symptoms of pain and also treats cold and flu symptoms.
WebMD notes that both Tylenol and Aleve are non-steroidal anti-inflammatory drugs (NSAIDs) and can react with other medications. Patients should consult a pharmacist or physician before taking either of these medications.
