The best over-the-counter medication for a hangover depends on which symptoms are bothering you most. For headaches, ibuprofen or naproxen are the safest choices. For nausea and stomach upset, bismuth subsalicylate (Pepto-Bismol) or an antacid can help. And one medication you should actively avoid is acetaminophen (Tylenol), which can cause serious liver damage when your body is still processing alcohol.
For Headaches: Ibuprofen or Naproxen
A standard dose of ibuprofen (Advil, Motrin) or naproxen (Aleve) is the go-to for hangover headaches. Both are anti-inflammatory painkillers that work well for the throbbing, dehydration-driven headache most people experience the morning after drinking. Take them with food and water, not on an empty stomach.
There’s a trade-off to be aware of: both ibuprofen and aspirin can irritate your stomach lining, and alcohol has already done some of that work overnight. If your hangover is more stomach-heavy than headache-heavy, you may want to hold off on these or at least eat something first. Naproxen lasts longer than ibuprofen (about 12 hours versus 4 to 6), so a single dose in the morning may carry you through.
Why You Should Skip Acetaminophen
Acetaminophen (Tylenol) is the one painkiller you want to avoid on a hangover. Your liver processes both alcohol and acetaminophen, and the combination creates a dangerous bottleneck. Normally, your liver handles acetaminophen through safe pathways. But when those pathways are overwhelmed, the drug gets rerouted through an enzyme called CYP2E1, which converts it into a toxic byproduct that damages liver cells directly.
Alcohol consumption ramps up CYP2E1 activity while simultaneously depleting your liver’s main protective molecule, glutathione. That means more of the toxic byproduct gets created and less of it gets neutralized. This isn’t just a theoretical concern. The combination of chronic or heavy drinking with acetaminophen is a well-documented cause of acute liver failure. Even if you’re not a regular drinker, your liver is already working hard the morning after, so give it one less thing to process.
For Nausea and Stomach Upset
Hangover nausea comes from a combination of excess stomach acid, irritation of the stomach lining, and the inflammatory effects of alcohol breakdown. A few OTC options can help, depending on severity.
Bismuth subsalicylate (Pepto-Bismol) coats the stomach lining and can ease both nausea and that unsettled, acidic feeling. It’s a reasonable first choice for mild to moderate stomach symptoms. Just keep in mind it contains a compound related to aspirin, so if you have aspirin sensitivity, skip it.
For acid reflux or a burning feeling in your chest and stomach, antacids like calcium carbonate (Tums) provide fast, short-term relief by neutralizing acid that’s already been produced. They work within minutes but wear off relatively quickly. If your stomach issues are more persistent, famotidine (Pepcid) takes a different approach: it reduces acid production at the source rather than neutralizing what’s already there. A single dose in the evening or at bedtime is most effective, so if you know a hangover is coming, taking one before bed can get ahead of the problem.
Rehydration Matters More Than Most Pills
No medication fully treats a hangover because the underlying cause is a combination of dehydration, inflammation, and the toxic byproducts of alcohol metabolism. Water alone helps, but adding electrolytes is better. Alcohol suppresses the hormone that tells your kidneys to retain water, so you lose sodium, potassium, and other minerals along with all that extra fluid. An oral rehydration solution, coconut water, or even a salty broth replaces what plain water can’t.
Drink a full glass of water with whatever medication you take. Many hangover symptoms that feel like they need a pill, especially fatigue and brain fog, improve significantly with fluids and food alone.
Supplements That Show Some Promise
Two supplements have at least preliminary evidence behind them, though neither is a guaranteed fix.
Dihydromyricetin (DHM) is a plant-derived compound found in many commercial hangover supplements. It has strong antioxidant and anti-inflammatory properties, and animal studies show it reduces the liver inflammation and fat accumulation caused by alcohol. In mice, DHM supplementation restored normal levels of key inflammatory markers and improved mitochondrial function in liver cells that had been damaged by ethanol exposure. It also boosted a protective molecule called IL-27, which helps repair the gut barrier after alcohol exposure. Human clinical data is still limited, but the animal evidence explains why it’s become a popular ingredient in hangover products.
Red ginseng has been tested in a small crossover study in healthy men. Participants who took a red ginseng drink had significantly lower blood alcohol levels at 30 and 60 minutes after drinking compared to placebo. The overall alcohol exposure (measured as area under the curve) was about 14% lower in the ginseng group. Researchers believe ginseng’s antioxidant properties help the liver clear alcohol and its toxic byproducts more efficiently. The evidence is early-stage, but the results were measurable.
Timing Your Medications
When you take something matters almost as much as what you take. Pain relievers work best once alcohol has largely cleared your system, typically by the morning after. Taking ibuprofen while you’re still drunk doesn’t help much and increases the risk of stomach irritation. If you’re dealing with acid reflux, taking famotidine before bed gives it time to reduce acid production overnight so you wake up in better shape.
For nausea, bismuth subsalicylate or an antacid can be taken as soon as symptoms start. Pair everything with water, food when you can tolerate it, and patience. Most hangovers resolve within 24 hours regardless of what you take, but the right combination of fluids, an anti-inflammatory painkiller, and something for your stomach can make those hours considerably more bearable.
