Naproxen is available over the counter under several brand names, with the most common being Aleve [1]. Other over-the-counter brands that contain naproxen sodium include Midol Extended Relief [2].
What is Naproxen and What Does It Treat?
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce fever, and decrease inflammation [3]. It is commonly used to treat conditions such as headaches, muscle aches, dental pain, menstrual cramps, and back pain [3].
How Does Naproxen Work?
Naproxen works by blocking the production of prostaglandins, which are natural substances in the body that cause inflammation, pain, and fever [3]. By inhibiting these substances, naproxen helps to alleviate these symptoms [3].
What is the Difference Between Naproxen and Ibuprofen?
Both naproxen and ibuprofen are NSAIDs used for pain and inflammation relief. A key difference is their duration of action; naproxen typically lasts longer than ibuprofen, meaning it can be dosed less frequently [4]. For example, Aleve (naproxen sodium) is often taken every 12 hours, while ibuprofen products may require dosing every 4 to 6 hours [1][4].
Are There Other Forms or Strengths of Naproxen?
Naproxen is available both over-the-counter (OTC) and by prescription in different strengths [3]. Over-the-counter versions, like Aleve, are generally lower doses suitable for self-treatment of common ailments [1]. Prescription strengths are available for more severe pain or inflammatory conditions [3].
Where Can I Buy Over-the-Counter Naproxen?
Over-the-counter naproxen products are widely available at most pharmacies, supermarkets, and online retailers [1].
What Are the Potential Side Effects of Naproxen?
Common side effects of naproxen can include stomach upset, heartburn, nausea, dizziness, and headache [3]. More serious side effects, though less common, can include stomach bleeding, kidney problems, and an increased risk of heart attack or stroke [3]. It is important to use the lowest effective dose for the shortest duration necessary [3].
When Does Naproxen Patent Expiration Matter?
Naproxen has been around for a long time and its original patents have long expired, allowing for the widespread availability of generic versions and over-the-counter formulations [5]. Patent expiration is primarily relevant for newer, branded drugs where it opens the door for generic competition and potential price reductions [5].
