Alka Seltzer is often used to ease hangover symptoms like headaches, body aches, and an upset stomach. It contains aspirin, sodium bicarbonate, and citric acid. These ingredients can help reduce pain and settle your stomach. Some people say it works fairly quickly, often within 15 to 20 minutes, but it’s not a complete fix for every hangover symptom.

In this article, we’ll look at what Alka Seltzer actually does, whether it’s good for nausea, how it compares to other options, and when it's safe to take it before or after drinking.

Is Alka Seltzer Good for Hangovers?

Yes, Alka Seltzer may help with some hangover symptoms, especially headaches, muscle aches, and mild indigestion. It works because of the combination of aspirin, which reduces inflammation, and antacids that help calm your stomach.

That said, it doesn’t treat the full range of hangover symptoms. Things like fatigue, dizziness, or brain fog aren’t really affected by Alka Seltzer. Also, the aspirin can irritate your stomach, especially if you’re already feeling nauseous or have not eaten.

So while it might give you some short-term relief, it's not a cure-all for hangovers. It’s best used when your symptoms are mild and mostly limited to pain or indigestion.

What Is Alka Seltzer and How Does It Work?

Alka Seltzer for hangoversAlka Seltzer is an over-the-counter medicine that comes in the form of fizzy tablets. You drop them in water, they dissolve quickly, and then you drink it. It’s commonly used for heartburn, indigestion, and minor aches.

Each tablet contains three active ingredients:

  • Aspirin, which is a pain reliever and anti-inflammatory

  • Sodium bicarbonate, an antacid that helps reduce stomach acid

  • Citric acid, which helps the tablets dissolve and adds to the antacid effect


Together, these ingredients work to relieve pain and calm an upset stomach. The fizzing action also helps get the medicine into your system a bit faster. Many people also use Alka Seltzer after drinking alcohol, hoping it will ease the next morning’s hangover.

Common Hangover Symptoms Alka Seltzer May Address

Alka Seltzer can help with a few specific symptoms, mostly related to pain and digestion. Here are some of the most common hangover symptoms it may relieve:

  • Headache and body aches – The aspirin in Alka Seltzer helps reduce inflammation and pain.

  • Indigestion or acid reflux – The antacids can neutralize excess stomach acid and reduce heartburn.

  • Mild fatigue or mental fog – Some users feel temporary relief from fatigue, though this may be more from hydration than the ingredients.


It will not help with dehydration, low blood sugar, or poor sleep, all of which contribute to hangovers.

Can You Take Alka Seltzer for Hangovers?

does Alka Seltzer help relieve hangover symptoms?You can take Alka Seltzer for hangovers, and it may give short-term relief from headaches, muscle pain, and an upset stomach. But it’s not a cure for all symptoms and may not be right for everyone.

Here are a few things to keep in mind:

  • It may help with headache and body aches, thanks to the aspirin.

  • It might ease indigestion or acid reflux from drinking.

  • It won’t fix dehydration, which is a major part of most hangovers.

  • Aspirin can irritate your stomach, especially if you're feeling nauseous or haven't eaten.

  • Always follow the label instructions, especially if you’re on other medications or have stomach issues.


If your hangover symptoms are severe or you're sensitive to aspirin, it’s better to talk to your doctor or pharmacist first.

Is Alka Seltzer Good for Nausea?

Alka Seltzer might help with nausea if it's related to acid buildup or indigestion. The sodium bicarbonate and citric acid can neutralize stomach acid, which may reduce that queasy, sour-stomach feeling. That’s why some people take Alka Seltzer after drinking alcohol when they wake up feeling sick.

However, it’s not always the best choice for nausea. One of the ingredients, aspirin, can actually make nausea worse for some people. Aspirin can irritate the stomach lining, especially on an empty stomach, which is common after a night of drinking.

So if your nausea is strong or ongoing, Alka Seltzer may not be the most helpful option. In some cases, a plain antacid or a rehydration drink without aspirin might be a better choice.

What About Alka Seltzer XS or Plus for Hangovers?

Alka Seltzer XS and Alka Seltzer Plus are slightly different from the original version. Alka Seltzer XS contains paracetamol (acetaminophen) and caffeine instead of aspirin. 

This combo is more targeted toward general pain and fatigue, which may be helpful during a hangover. However, the dose of acetaminophen in XS is quite low compared to the usual adult dosage.

Alka Seltzer Plus is usually made for cold and flu symptoms and may contain extra ingredients like antihistamines or decongestants. These aren't really needed for a hangover and could even make you feel groggier. 

So while XS might be mildly helpful, Alka Seltzer Plus isn’t really made with hangovers in mind.

Can You Mix Alka Seltzer and Alcohol?

It’s best not to take Alka Seltzer while you’re still drinking alcohol. Mixing aspirin with alcohol can increase the risk of stomach irritation or even internal bleeding, especially if you have a sensitive stomach or drink heavily.

Alka Seltzer is meant to be taken after drinking, once the effects of alcohol are wearing off. If you’re using it to prepare your stomach before drinking, that’s not a good idea either. It won’t prevent a hangover and may actually cause more discomfort.

If you’ve already taken Alka Seltzer and are thinking about having another drink soon after, it’s better to wait. 

Give your body some time to process the medicine first. When in doubt, talk to your doctor or pharmacist, especially if you take other medications regularly.

How Long After Taking Alka Seltzer Can I Drink Alcohol?

You should wait at least a few hours after taking Alka Seltzer before drinking alcohol again. This gives your body time to absorb and process the aspirin and other ingredients.

Drinking too soon after taking Alka Seltzer can increase your risk of stomach problems. Aspirin and alcohol both irritate the stomach lining, and combining them close together may raise your risk of discomfort or even bleeding. 

It’s better to let your body rest and recover rather than jump back into drinking.

If you're planning to drink again the same day, consider using a non-aspirin alternative or spacing things out with food and water in between.

Is It Safe to Take Alka Seltzer on an Empty Stomach?

It’s usually not recommended to take Alka Seltzer on an empty stomach. The aspirin in it can be harsh on your stomach lining, especially if you haven’t eaten anything.

Taking it without food might lead to nausea or stomach pain, and in some cases, it could make acid reflux worse. If you’re already feeling sick after a night of drinking, this could add to your discomfort.

To stay on the safe side, try to eat a small meal or snack before taking Alka Seltzer. Something light like toast or a banana can help cushion your stomach and reduce the chances of irritation.

Are There Any Side Effects of Taking Alka Seltzer for a Hangover?

Alka Seltzer can cause side effects, especially if taken on an empty stomach or too close to alcohol. The most common issues are stomach irritation, nausea, or acid reflux due to the aspirin.

In some cases, it can lead to more serious problems like bleeding in the stomach or allergic reactions. The reason why it's not recommended for people with indigestion is because there's a risk of serious bleeding from stomach ulcers. 

The FDA has also issued a warning about this. This risk increases if you take it often or already have gut issues (1). 

Always check the label, and if you’re taking other medications or have health concerns, talk to your doctor or pharmacist first.

When to Take Alka Seltzer for Hangovers

Timing can make a difference in how well Alka Seltzer works for hangover relief. You want to take it when symptoms are showing up, but not too early or too late.

  • In the morning after drinking, once you’re feeling symptoms like headache or indigestion

  • After eating something light, so your stomach isn’t empty

  • Before a nap or rest, to help relieve aches while you recharge

  • When you’re staying hydrated, since water helps with recovery too

When to Avoid Alka Seltzer for Hangovers

Alka Seltzer isn’t the right choice for everyone. There are times when it’s better to skip it and try something else.

  • If you have a sensitive stomach or ulcers, since aspirin can make it worse

  • If you’re allergic to aspirin or NSAIDs, which can cause reactions

  • If you’re already taking blood thinners, to avoid possible interactions

  • If you haven’t eaten, as it may irritate your stomach

  • If you're still drinking alcohol, because it can increase the risk of side effects

Better Alternatives to Alka Seltzer for Hangover Relief

Alka Seltzer might help with a few symptoms, but it doesn’t cover everything. These options focus on hydration, nutrients, and gentle stomach support—things your body actually needs after drinking.

Oral Rehydration Solutions (ORS)

ORS drinks like Liquid I.V. or Pedialyte help you rehydrate faster than plain water. They contain electrolytes like sodium and potassium to restore balance and reduce fatigue. 

Magnesium and B Vitamins

Alcohol drains your body of magnesium and B vitamins, which are key for energy and brain function. 

Low levels can make hangovers feel worse. Taking a B-complex and magnesium the next day may ease brain fog and muscle soreness.

Ginger Tea or Peppermint Tea

Both teas are gentle on your stomach and can help with nausea or bloating. Ginger is backed by research for calming nausea, and peppermint helps relax your digestive system. 

They’re a soothing option when you're feeling queasy.

Specialty Hangover Supplements

These are made to support recovery with ingredients like milk thistle, prickly pear, and NAC. Some studies suggest they may help reduce inflammation and oxidative stress from drinking.Omre AfterdrinkIf you want a complete recovery formula with research-backed ingredients, AFTERDRINK® is worth checking out. It’s a smart pick for those looking to feel better after a night out.

Other Tips for Hangover Recovery

Alka Seltzer can help a little, but it’s just one part of getting back on your feet. Here are some practical things you can do that really make a difference:

  • Drink lots of water – Alcohol dehydrates you, so aim for small sips throughout the day.

  • Eat something gentle – Toast, bananas, or soup can settle your stomach and give you energy.

  • Rest and sleep – Your body needs time to recover. Don’t push yourself too hard.

  • Avoid more alcohol – The “hair of the dog” doesn’t really help and can make things worse.

  • Take a cool shower – It can freshen you up and reduce that heavy, sluggish feeling.

  • Limit caffeine – A little might help with energy, but too much can irritate your stomach and make dehydration worse.

Final Words

Alka Seltzer can offer some relief from hangover symptoms like headaches and indigestion, thanks to its mix of aspirin and antacids. 

But it doesn’t fix everything. It won’t help much with fatigue, nausea, or dehydration—and for some people, it may even make things worse.

If you choose to use it, timing matters. Take it after drinking, not during, and ideally after eating something light. 

For those looking for more complete recovery, options like rehydration drinks, B vitamins, herbal teas, or targeted hangover supplements like AFTERDRINK may work better. 

Always consider your own health conditions and talk to a pharmacist or doctor if you’re unsure.
