An Open-label, Single-arm, Multiple-dose Study to Evaluate the Safety of a Fixed Combination of Acetaminophen/Naproxen Sodium in Adolescents 12 to Less Than 17 Years of Age With Orthodontic Pain

The purpose of this study is to evaluate the safety of a fixed combination of acetaminophen/naproxen sodium when administered as multiple doses over a period of up to 10 days in adolescents 12 to below 17 years of age with post-procedure orthodontic pain.

Inclusion Criteria:

• Have a known allergy or hypersensitivity to naproxen (or other nonsteroidal anti-inflammatory drugs including aspirin) or acetaminophen or have asthma
• Have presence or a history of major medical condition that in the Investigator's opinion may jeopardize the participant's safety or wellbeing or the integrity of the study
