How Long Does It Take for the Effects to Wear Off?

Generally speaking, it takes about two to four hours for the effects of Alka Seltzer to wear off. The length of time it takes for Alka Seltzer to wear off varies depending on the individual and their body size. The amount of Alka Seltzer taken also affects how long it will stay in the system.

Alka Seltzer

Generally speaking, for adults, a small amount of Alka Seltzer will take 2-4 hours to wear off, while a greater amount may take 4-6 hours to wear off. It is important to note that other medications may interact with Alka Seltzer and could increase or decrease its effectiveness or prolong the time it takes to wear off.

What is Alka Seltzer?

Alka Seltzer is a combination of three medications – aspirin, citric acid, and sodium bicarbonate – used to treat symptoms like upset stomach and indigestion that causes headaches or body aches.

How Does Alka Seltzer Work?

Alka-Seltzer is an antacid that relieves indigestion and upset stomach by neutralizing the acid in your stomach. It contains three active ingredients: aspirin (acetylsalicylic acid), sodium bicarbonate, and anhydrous citric acid.

When the tablet is placed in water, these ingredients react to produce carbon dioxide gas, resulting in a fizzing sound. The aspirin and sodium bicarbonate work together as a “buffer,” which neutralizes stomach acid and temporarily keeps it from irritating your lining.

Generally, each Alka-Seltzer tablet contains about 1.9 grams of sodium bicarbonate and about 1.0 grams of citric acid. When these ingredients are dissolved in water, they instantly reduce the amount of acid in the stomach, relieving the symptoms of heartburn.

The Side Effects of Alka Seltzer

Alka Seltzer has a few common side effects, such as nausea, vomiting, dizziness, and headaches. These symptoms should pass within 4 to 6 hours after taking the medication. Other rarer side effects include allergic reactions, stomach pain, and difficulty breathing. If these symptoms occur, it is important to seek medical help immediately.

Are There Any Alternatives to Taking Alka Seltzer?

You can also try eating small meals that are easy to digest throughout the day. Probiotics may also help restore the balance of bacteria in your digestive system. Also, getting plenty of rest and reducing stress can help you recover faster from a cold or flu.

Drinking plenty of water can also help with hydration. A pinch of baking soda dissolved in water can temporarily relieve heartburn or acid indigestion. However, it is important not to take Alka Seltzer for more than 10 days in a row, as this medication is designed for short-term use only.

When should you not take Alka-Seltzer?

People should not take Alka-Seltzer with systemic mastocytosis, low vitamin K levels, gout, a decrease in the blood clotting protein prothrombin, or von Willebrand’s disease. It is also not recommended for pregnant women or people who have taken an MAO inhibitor in the past 14 days. People with anemia or hemophilia or who are taking additional caffeine should also avoid taking Alka-Seltzer.

Lastly, women in their third trimester of pregnancy should not take Alka-Seltzer originally and should avoid taking it with acetaminophen. High blood pressure should not be surprising, but it is important to note that Alka-Seltzer should not be taken with high blood pressure.

Who Should Not Take Alka Seltzer?

People who should not take Alka Seltzer include those with an active stomach ulcer, any bleeding problem, or a history of allergic reaction to aspirin, Caffeine, or other ingredients listed on the package label.

Additionally, pregnant women should not use this medicine during the last three months of pregnancy. People should also avoid taking Alka Seltzer Plus C/C(PE, DM) and similar chlorpheniramine medicines. Alka Seltzer is not recommended for children under 12 years of age. Before taking any medicine containing Alka Seltzer, individuals should consult a doctor and discuss their medical history to ensure it is safe.
