Most healthy adults can take ibuprofen for a hangover headache if the label allows, ideally with food after they've stopped drinking; acetaminophen (Tylenol) is best avoided after heavy drinking, because NIAAA says alcohol plus acetaminophen can be toxic to the liver. So can you take ibuprofen for a hangover? Usually, yes, but NSAIDs such as ibuprofen, naproxen and aspirin carry their own stomach-bleeding warning with alcohol. Follow the label, and ask a pharmacist if you have stomach, kidney, liver or bleeding problems, drink daily or take other medicines.
Key takeaways
- NIAAA warns that "the combination of alcohol and acetaminophen can be toxic to the liver."1
- FDA-required labels warn that severe liver damage may occur with acetaminophen, and that the chance of severe stomach bleeding from NSAIDs is higher, if you have 3 or more alcoholic drinks every day while using them.2
- In a placebo-controlled trial of 150 people with hangovers, the NSAID loxoprofen eased headache but not fatigue or nausea.3
- As of a 2022 review, acetaminophen and aspirin had not been tested in placebo-controlled hangover trials.4
The short answer: can you take ibuprofen for a hangover?
Usually, for healthy adults who've stopped drinking and eaten, if the label allows. Skip acetaminophen after a heavy night.
| Pain reliever | Main concern with alcohol | Hangover evidence |
|---|---|---|
| Acetaminophen (Tylenol; also in many combination products) | Liver damage; label warns about 3+ drinks a day and other acetaminophen products2 | Not tested against placebo4 |
| Ibuprofen (Advil, Motrin), naproxen (Aleve) | Stomach bleeding; label warns about 3+ drinks a day; kidney and diuretic cautions2 | A related NSAID eased headache in one trial3 |
| Aspirin | Same NSAID stomach-bleeding warning2 | Not tested against placebo4 |
None is approved for hangovers. See how to cure a hangover.
Acetaminophen (Tylenol) and alcohol: the liver issue
Together, alcohol and acetaminophen can be toxic to the liver. NIAAA notes that some people take it before bed after drinking, which is exactly the combination it warns about.1
The FDA-required "Liver warning" says severe liver damage may occur if you take more than the label's daily maximum, take it with other acetaminophen products, or have 3 or more alcoholic drinks every day while using it.2 FDA adds that too much acetaminophen "can lead to liver failure and death," and that it's in hundreds of over-the-counter and prescription drugs.5
Overdose symptoms such as nausea, vomiting and upper belly pain can look like a hangover. If you think you've taken too much, get medical help right away, even if you feel fine, or call Poison Control at 1-800-222-1222.6 More in how your body processes alcohol and liver support after drinking.
Ibuprofen, naproxen and aspirin: stomach, kidney and bleeding cautions
NSAIDs don't carry acetaminophen's liver warning, but they irritate the stomach, and so does alcohol. NIAAA says aspirin and ibuprofen can increase stomach acid and advises caution before or after drinking.1
The FDA-required "Stomach bleeding warning" says the chance is higher if you're 60 or older, have had ulcers or bleeding problems, take a blood thinner, a steroid or another NSAID, have 3 or more drinks every day while using the product, or take more or for longer than directed.2 People with high blood pressure, heart disease, liver cirrhosis or kidney disease, or who take a diuretic, should ask a doctor first. MedlinePlus adds that NSAIDs other than aspirin may raise the risk of heart attack and stroke, that stomach-bleeding risk is higher in people who drink large amounts of alcohol while taking ibuprofen, and that ibuprofen may be taken with food or milk to prevent stomach upset.7
The best evidence is a Japanese trial in which 150 people with hangovers were analyzed.3 A single dose of loxoprofen, an NSAID, eased headache more than placebo but not fatigue or nausea, with similar stomach discomfort (2.7% vs. 3.9%). Ibuprofen and naproxen are in the same class but weren't tested.
Timing: wait until you've stopped drinking
Skip pain relievers while drinking and at bedtime after a night out. No study has defined a safe wait; the practical rule is morning, after food, per the label.
NIAAA notes that alcohol and medicines "can interact harmfully even if they are not taken at the same time."8 Many adults clear roughly one standard drink every one to two hours, so after a heavy night some alcohol may still be in your system in the morning.9 If you drank a lot or can't keep food down, ask a pharmacist.
Is any medicine approved for hangovers? And watch combination products
As of October 2026, we found no drug that FDA has approved specifically to prevent or treat hangovers. In 2020, FDA warned seven companies that supplements claiming to cure or prevent hangovers are unapproved new drugs, and said consumers shouldn't rely on them "as an alternative to responsibly limiting their consumption."10
Watch multi-symptom products: some headache products combine aspirin and acetaminophen, and NIAAA warns that cold, flu and allergy products can cause drowsiness, dizziness and an increased risk of overdose with alcohol, and lists OTC sleep aids as harmful combinations too.8 If you pack a pain reliever in a hangover kit, choose a single-ingredient one and keep the label.
Who should avoid all of them (or ask first)
Ask a pharmacist or doctor before taking any of these after drinking if you have liver disease, kidney disease, heart disease, high blood pressure or a history of ulcers or stomach bleeding; take a blood thinner, steroid, diuretic or any prescription medicine; are 60 or older; drink 3 or more drinks a day; or are pregnant or breastfeeding.2, 6
Federal guidance is "Consume less alcohol for better overall health," and people on medicines that interact with alcohol should avoid it completely.11 Hangovers impair coordination, so don't drive while hungover.1
Non-drug alternatives
NIAAA says there is "no cure for a hangover other than time."1 Meanwhile: rest in a dark, quiet room, drink water for thirst, eat something bland, and skip "hair of the dog," which NIAAA says can prolong symptoms.1
Some headaches aren't hangovers. Get help right away for a sudden, explosive or "worst ever" headache, one after a head injury, or one with fever, stiff neck, confusion, slurred speech or weakness.12 See hangover headache.
What we don't know yet
- Whether acetaminophen, aspirin, ibuprofen or naproxen beat placebo for hangovers; the trial evidence covers a different NSAID.
- How long to wait after drinking before an NSAID is safe for a given person.

Frequently asked questions
Can I take Tylenol after drinking?
It's best avoided after heavy drinking. NIAAA says alcohol plus acetaminophen can be toxic to the liver, and the FDA-required label warns of severe liver damage in people who have 3 or more drinks every day while using it. If you're unsure, ask a pharmacist.
How long after drinking can I take ibuprofen?
No study has set a safe interval. Wait until you've stopped drinking and alcohol has had time to clear, then take it with food as the label directs. If you drank heavily or have stomach, kidney or bleeding problems, ask a pharmacist first.
Is aspirin good for a hangover?
Aspirin hasn't been tested against placebo for hangovers, and as an NSAID it carries the same stomach-bleeding warning with alcohol as ibuprofen. Check combination products, which may also contain acetaminophen.
Can I take ibuprofen before bed after drinking?
It's better to wait until morning. At bedtime alcohol is still in your system, NIAAA advises caution with ibuprofen around drinking, and there's no evidence a bedtime dose prevents a hangover. Avoid acetaminophen at bedtime after drinking.
Is any over-the-counter medicine approved for hangovers?
Not that we found. As of October 2026, we found no drug FDA has approved specifically to prevent or treat hangovers; single-ingredient pain relievers are labeled for symptoms such as headache and minor aches. In 2020, FDA warned seven companies that supplements claiming to cure or prevent hangovers were unapproved new drugs.
