What Is Alka Selzer®?

The original Alka Selzer® formula is an effervescent pain reliever and antacid made with sodium bicarbonate, aspirin, and citric acid. Today, the brand also makes antacid chews, tablets, heartburn relief gum, and products intended to help with cold and flu symptoms. People have trusted the brand to alleviate heartburn for nearly 90 years.

What Does Alka Selzer® Do?

Alka Selzer® helps provide fast relief from acid indigestion, sour stomach, and heartburn. Products like the original Alka Selzer® made with aspirin can also help with fever, headaches, and body aches. Together, the combination of ingredients helps minimize excess stomach acid and alleviate overall discomfort. When you drop Alka Selzer® effervescent tablets in water, they fizz.

How Does Alka Selzer® Work?

Alka Selzer® works by neutralizing stomach acid, an effect that can help alleviate digestive upset. Alka Selzer® products can also help with excess gas and bloating. There are several advantages to using Alka Selzer® effervescent tablets that you won't get anywhere else. Since Alka Selzer® effervescent tablets dissolve quickly, they start to work almost instantly.

How Often Can You Take Alka Selzer®?

How often you can take any Alka Selzer® product depends on the nature of the product you select. You'll find dosage recommendations for individual products printed directly on the packaging. Children and teens recovering from flu-like symptoms or chickenpox should not take any product containing aspirin. Ask your doctor before using Alka Selzer® if you have a history of stomach issues.  

How Long Does It Take Alka Selzer® To Work?

Most people find that Alka Selzer® products deliver fast relief. With some Alka Selzer® products, many people report feeling better in as little as 30 minutes. According to the manufacturer's website, the active ingredients in Alka Selzer® Cool Action Heartburn Relief Gum start working instantly.

How To Take Alka Selzer®

Heartburn can strike at any time. Some of the most common triggers are spices, fatty foods, alcohol, and stress. Most Alka Selzer® products are intended to be taken at the first sign of discomfort. However, if you have a known medical condition or take medication, consult your health care provider. Antacids can interact with several prescription medications.

When using Alka Selzer® effervescent tablets, drop your tablets into a glass of room temperature water according to package directions. Using cold water can cause excessive foaming and slow the rate of dissolution.
