The best over-the-counter (OTC) pain reliever choice typically depends on what symptoms you are treating and whether there are any contraindications. Aleve (naproxen), for example, is the strongest available OTC non-steroidal anti-inflammatory pain reliever. However, there is an increased risk of gastrointestinal side effects with naproxen, so it may not be appropriate for some individuals.

The active ingredient in OTC pain medications and fever reducers varies. Which medication is appropriate depends on the condition you are treating, the type of pain you are experiencing, your medical history, and if you are trying to reduce a fever.
