      DRUG PURPOSE
      Acetaminophen Pain Reliever/Fever Reducer

      Do the Alka-Seltzer Plus® Effervescent tablets and Liquid Gels contain the same ingredients?

      Not necessarily. Please be sure to read all labels carefully and follow directions as stated. 

      Can I use the Alka-Seltzer Plus® Night Cold Formula during the day?

      Alka-Seltzer Plus® Night Cold is recommended for bedtime as it may cause marked drowsiness. 

      How many days can I use Alka-Seltzer Plus®?

      Discontinue use and consult a physician if pain, cough or nasal congestion gets worse or lasts longer than seven days, or if fever gets worse or lasts longer than three days. 

      How much water should I use when taking the effervescent tablets?

      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.) 

      What temperature of water should I use to dissolve Alka-Seltzer Plus® Effervescent 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. 

      What should I do if the tablets don't fizz?

      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.

      Can I use the Alka-Seltzer Plus® formulas beyond the expiration date?

      We don't recommend using our products after they expire. We recommend you discard expired Alka-Seltzer Plus® products.

      Can I use Alka-Seltzer Plus® products if I'm pregnant or nursing?

      If you're pregnant or breastfeeding, contact your physician before using this product. 

      Where can I find the dosage directions on the Alka-Seltzer Plus® Day & Night Formulas?

The information with the orange background (on the left) pertains to our Day Cold Formula, while the information with the green background (on the right) pertains to the Night Cold Formula.

View the directions online by visiting our product page. 

      Can I use Alka-Seltzer Plus® with other medications?

      Consult your health care provider before taking more than one medication, as interactions between drugs are always possible.
