Is Naproxen and Aleve the Same Thing?

Is Naproxen and Aleve the Same Thing?

Naproxen and Aleve are not exactly the same thing, but they are closely related. Naproxen is the active drug ingredient, while Aleve is a brand name that delivers naproxen sodium over the counter. If you take Aleve, you are taking naproxen, but not all naproxen is Aleve.

The Active Ingredient

Both products contain naproxen, a nonsteroidal anti-inflammatory drug (NSAID) that reduces hormones causing pain and inflammation. Aleve uses naproxen sodium, a salt form of naproxen that the body absorbs a little faster than naproxen base. Prescription-strength naproxen, such as Naprosyn or Anaprox, uses naproxen sodium or naproxen itself and often comes in higher doses than the OTC Aleve tablet.

Prescription vs. Over-the-Counter

The main practical difference is strength and access. Aleve is sold without a prescription at 220 mg per tablet, typically taken every 8 to 12 hours. Prescription naproxen products can be 250 mg, 375 mg, or 500 mg and require a doctor's supervision. The prescription forms also come in delayed-release or combination products that Aleve does not offer.

Which One Should You Use?

For mild to moderate pain, occasional use of Aleve is often sufficient. For chronic conditions like arthritis, a doctor may prescribe a higher-strength naproxen product to manage symptoms more effectively. The choice depends on the condition, severity, and individual health factors such as heart, kidney, or stomach risk.

Side Effects and Risks

Because they share the same active ingredient, the side effect profiles are similar. Common risks include stomach irritation, heartburn, dizziness, and fluid retention. Long-term or high-dose use of any naproxen product increases the chance of cardiovascular events or gastrointestinal bleeding. Always use the lowest effective dose for the shortest time needed.
