Alka-Seltzer is a fast-acting, versatile, over-the-counter remedy for a variety of ailments. Because it is aspirin based, it acts as a pain reliever and anti-inflammatory. The double antacids delivered in an effervescent rush begin to relieve acid indigestion, heartburn and upset stomach on contact. The overall combination of active ingredients in this fizzy tonic provides speedy relief.

Faster Indigestion Relief
Alka-Seltzer neutralizes stomach acid on contact. The bubbling action provides relief of indigestion much faster than many other OTC antacid products. It takes orally ingested tablets from 15 to 30 minutes to dissolve after taking them, but when you drop two tablets into the recommended 4 ounces of water, you can see, hear and feel the fizzy effervescence. Those bubbles are the result of a series of chemical interactions that will begin to work instantly the moment you take it.

The Combination of Ingredients Makes Alka-Seltzer Versatile and Effective
All products from this brand contain at least two antacids, anhydrous citric acid and sodium bicarbonate. When these two ingredients mix in water, the well-known fizz is created. This renowned reaction is not just for show; it plays a major role in how this tonic produces results. The effervescent reaction is what alleviates your stomach discomfort and helps push aspirin, the third active ingredient, through the body to aid in relieving head and body aches as well as inflammation. This potent trio of ingredients has been providing a restorative elixir for more than 75 years.

Who Makes Alka-Seltzer?
These fizzy tabs were introduced to the market in 1931 by Miles Laboratories. In 1978, Bayer, the most trusted name in aspirin for over a century, purchased Miles Laboratories and is the current manufacturer.

Should Alka-Seltzer Tablets Be Dissolved in Cold or Warm Water?
The recommended 4 ounces of water the tablets are dissolved in should, ideally, be room temperature. Cold water will slow down the rate at which the tablets dissolve, and warm water will cause excessive foaming.

Can Anyone Take This Medication?
You should not take it if you are allergic to citric acid, aspirin or any other type of NSAID (non-steroidal anti-inflammatory drug) or if you are currently taking another anti-inflammatory. Individuals with any history of gastrointestinal disease, heart problems or those taking blood thinners or other medications to prevent blood clotting, lower blood pressure or lower blood sugar are also cautioned against taking this medication. Contraindications also exist for other conditions. If you have existing medical conditions or take any prescription medication, it is best to check with your doctor before taking any over-the-counter medications.

What Else can Alka-Seltzer be Used For?
In addition to all its medical uses, this unique product can also be useful in an educational setting to show a variety of chemical reactions. It can be used to test the effect of temperature on the rate of reaction, to create eruptions and various other experiments. You can even make an Alka-Seltzer powered rocket. Who knew you could have so much fun with an antacid?
