The best over-the-counter medicine for a hangover depends on which symptoms are hitting you hardest. For headaches, ibuprofen or naproxen are the go-to options. For nausea and stomach upset, an antacid or acid-reducing tablet can help. There’s no single pill that erases a hangover, but the right combination of a pain reliever, something for your stomach, and aggressive rehydration covers most of the misery.
Ibuprofen for Headaches, Not Acetaminophen
Anti-inflammatory pain relievers like ibuprofen (Advil, Motrin) and naproxen (Aleve) are the safest choices for a hangover headache. They reduce the inflammation that alcohol triggers in your body and brain. Take a standard dose with food and water.
Aspirin works too, but it’s harsher on an already irritated stomach. All of these can cause some stomach upset when combined with the aftereffects of alcohol, so eating something before or alongside the dose makes a real difference.
Acetaminophen (Tylenol) is the one to avoid. Your liver processes both acetaminophen and alcohol using the same enzyme pathway. Alcohol increases the production of a toxic byproduct during acetaminophen breakdown, and heavy drinking depletes your liver’s natural defenses against that byproduct. For people who drink regularly, even normal doses of acetaminophen taken repeatedly can stress the liver. A single standard dose after a night out is unlikely to cause serious harm in an otherwise healthy person, but ibuprofen is simply the smarter pick when alcohol is in the picture.
Stomach Relief: Antacids and Acid Reducers
Alcohol ramps up acid production in your stomach and irritates the lining directly. That’s why hangovers often come with heartburn, nausea, and a sour, unsettled feeling. Two types of over-the-counter medications help here, and they work differently.
Antacids like Tums or Rolaids neutralize stomach acid on contact. They work fast, usually within minutes, but the relief doesn’t last long. If your main complaint is a burning sensation or acid taste, these are a quick fix.
H2 blockers like famotidine (Pepcid) actually reduce the amount of acid your stomach produces. They take about an hour to kick in, but the effects last much longer. Famotidine can help with indigestion, stomach pain, heartburn, nausea, and that general sour-stomach feeling. Some people take one before they start drinking, giving it 30 to 60 minutes to get ahead of the acid surge, but it also works after the fact.
If your nausea is severe, bismuth subsalicylate (Pepto-Bismol) coats the stomach lining and can calm things down. Just know that it contains a compound related to aspirin, so don’t combine it with aspirin or ibuprofen.
Rehydration: More Than Just Water
Alcohol is a diuretic, meaning it makes you urinate more than the volume of fluid you’re taking in. You also lose electrolytes, minerals like sodium and potassium that your cells need to function properly, every time you urinate, sweat, or vomit. This fluid and mineral loss drives many hangover symptoms: fatigue, dizziness, dry mouth, and brain fog.
Plain water replaces lost fluid, and drinking it is far better than drinking nothing. But water doesn’t contain electrolytes. Oral rehydration solutions like Pedialyte contain a specific ratio of sugar and salt designed to pull fluid into your bloodstream faster than water alone. They also replenish the sodium and potassium you’ve lost. Sports drinks like Gatorade fall somewhere in between: they contain some electrolytes but also more sugar than a true rehydration solution.
The practical move is to alternate between water and an electrolyte drink. Start before bed if you can, and keep drinking steadily the next morning.
Supplements That May Help
A few supplements have some research behind them, though none are miracle cures.
- Dihydromyricetin (DHM): This plant compound, extracted from the Japanese raisin tree, has shown promise in animal studies. In mice with alcohol-induced liver injury, DHM reduced fat buildup in the liver and appeared to enhance alcohol metabolism. It also has anti-inflammatory and antioxidant properties. The typical supplement dose ranges from 300 to 1,000 mg daily. Human research is still limited, but DHM is one of the more popular ingredients in hangover supplement blends for a reason.
- L-cysteine: This amino acid may help your body break down acetaldehyde, the toxic byproduct of alcohol metabolism that contributes to headaches and nausea. A clinical study found that 1,200 mg of L-cysteine (taken as part of a vitamin supplement) reduced hangover severity, nausea, and headache. A lower dose of 600 mg was enough to ease stress and anxiety symptoms. These results are preliminary but encouraging.
- Vitamin B6: One study found that 1,200 mg of pyritinol (a form of vitamin B6) reduced the number of hangover symptoms participants reported. However, a separate placebo-controlled study using a B-vitamin blend found no significant improvement in general wellbeing, though a few specific symptoms like restlessness improved. B vitamins are depleted by alcohol, so replenishing them isn’t a bad idea, but don’t expect dramatic results.
A Practical Hangover Plan
Knowing which medicines are available is useful, but timing and combination matter. Here’s what a solid recovery routine looks like:
Before bed, drink a full glass of water or an electrolyte drink and eat a small snack. If your stomach already feels acidic, take an antacid or famotidine.
When you wake up, take ibuprofen with food, not on an empty stomach. Even a few crackers or a piece of toast counts. Drink another 16 to 20 ounces of fluid, ideally something with electrolytes. If nausea or heartburn is a problem, add an antacid or Pepto-Bismol.
Continue eating bland, easy-to-digest food throughout the morning. Your body needs calories to finish processing the alcohol, and food helps buffer stomach acid. Bananas are a good choice because they’re gentle on the stomach and contain potassium. Eggs contain cysteine, the same amino acid studied in supplement form for hangover relief.
Most hangovers resolve within 24 hours. If you’re still feeling significantly ill after that, or if you experience confusion, seizures, or persistent vomiting, that’s a sign something more serious is going on.
