Aleve Pain Reliever/Fever Reducer

Aleve is a well-known brand of over-the-counter pain relief medication specifically containing naproxen sodium. The brand was originally developed and introduced by Syntex Corporation in the United States. Following various mergers and acquisitions within the pharmaceutical industry, the brand's ownership moved to Bayer AG, the German multinational pharmaceutical and biotechnology company.

Today, Aleve is produced in multiple global locations to serve different markets, with primary manufacturing operations often centralized in Germany and the United States. As one of Bayer's flagship consumer healthcare products, Aleve remains a global leader in the pain management category, marketed by Bayer's Consumer Health division which is headquartered in Switzerland, though the parent ultimate owner company is based in Leverkusen, Germany.
