ALKA-SELTZER PLUS Brand Guide

Alka-Seltzer Plus Brand Overview and History

Alka-Seltzer Plus is a flagship line from Bayer, a global leader in healthcare products, extending the legacy of the original Alka-Seltzer introduced in 1931. The classic Alka-Seltzer revolutionized over-the-counter relief with its fizzy, effervescent formula that combines aspirin, sodium bicarbonate, and citric acid for quick heartburn and pain relief. Building on this innovation, Alka-Seltzer Plus launched in the 1980s to tackle the full spectrum of cold and flu symptoms. Today, it's a go-to brand in the Cough & Cold > Cold & Flu Relief category under Health Care > Over-the-Counter Medication. Renowned for its fast-dissolving tablets that deliver maximum strength ingredients directly into your system, Alka-Seltzer Plus has earned a reputation for efficacy and convenience. With decades of trust from consumers worldwide, the brand continues to evolve, offering targeted formulas for adults and children 12 years and older, ensuring you're back on your feet faster during peak illness seasons.
