How much water should I use when taking the effervescent tablets?
It’s recommended to use 4 ounces of water to dissolve 2 tablets.
Can I dissolve Alka-Seltzer Plus® Effervescent tablets in something other than water?
They dissolve best in water. Other liquids may contain ingredients that delay or affect dissolution. For example, milk contains compounds such as protein and fat, so it takes longer to dissolve the tablets.

Room temperature works best since cold water slows the dissolution and warm water can make the product foam excessively. The surface of the tablet needs to be submerged completely in water for rapid dissolution.

The tablets may have been exposed to moisture due to a slight imperfection or small hole in the foil or packaging and should not be used.
