Can I Take Zofran After Drinking Alcohol?
Zofran (ondansetron) is a prescription anti-nausea medicine approved for nausea and vomiting caused by cancer chemotherapy, radiotherapy and surgery. A hangover is not one of its approved uses. Its FDA label does not list alcohol as an interaction, but it carries heart-rhythm and serotonin warnings, so ask a doctor or pharmacist before taking it after drinking. The NIAAA says nothing cures a hangover except time.

What Zofran is approved for
The FDA-approved label (revised February 2025) says Zofran (ondansetron) is indicated for the prevention of:
- nausea and vomiting with highly emetogenic cancer chemotherapy
- nausea and vomiting with initial and repeat courses of moderately emetogenic chemotherapy
- nausea and vomiting with certain radiotherapy
- nausea and/or vomiting after surgery
Nausea from a hangover is not on that list, so using Zofran for a hangover is outside its approved use.
Can you take Zofran after drinking alcohol?
The label’s interaction section names other medicines, not alcohol. That does not make it a hangover remedy. The label warns about:
- Heart rhythm (QT prolongation): ECG changes and rare cases of Torsade de Pointes have been reported.
- Serotonin syndrome: reported with this class of medicine, especially together with other serotonergic drugs.
- Common side effects: headache, tiredness, constipation and diarrhea.
If you take other medicines, have heart problems, or were prescribed Zofran for something else, ask your doctor or pharmacist before combining it with drinking.
Does Zofran help a hangover?
The NIAAA says there is no cure for a hangover other than time, and that none of the remedies promoted online have been scientifically proven to work. Typical hangover symptoms include fatigue, thirst, headache, muscle aches, nausea and stomach pain.
The NIAAA also warns that acetaminophen (Tylenol) together with alcohol can be toxic to the liver, and that aspirin and ibuprofen can irritate the stomach.
When vomiting after drinking is an emergency
Vomiting can be a sign of alcohol overdose. The NIAAA says to call 911 right away if someone who has been drinking has mental confusion, is hard to wake, has seizures, slow or irregular breathing, clammy or bluish skin, or a very low body temperature. Do not leave them alone, and if they are lying down, roll them onto their side.

Can you mix Zofran and alcohol, or take it while drinking?
No official page says you cannot, and none says you can. The generic ondansetron tablet label (DailyMed) does not mention alcohol, and neither does MedlinePlus, so there is no official rule on whether you can drink alcohol while taking Zofran (ondansetron). The label does say that people with liver impairment and people over 75 clear the drug more slowly, so a safe gap may differ from person to person. It does not treat wine, beer or liquor differently. Ask your pharmacist about your dose.
How long after Zofran can you drink alcohol?
No official page gives a waiting time. See the answer above and ask your pharmacist.
Is it okay to take Zofran when drunk or hungover? Will it help a hangover?
The label does not say. It covers nausea from chemotherapy, radiotherapy and surgery, so nausea from drinking is outside its approved use. We found no official source showing Zofran works for a hangover. The NIAAA says there is no cure for a hangover other than time, and that symptoms can last 24 hours or longer.
Can you take two Zofran at once?
Only if your prescriber told you to. MedlinePlus says not to take more than prescribed or more often, and not to take a double dose after a missed one. The label sets doses by use, for example 8 mg before moderately emetogenic chemotherapy, and caps severe liver impairment at 8 mg a day. For an overdose call poison control at 1-800-222-1222, or 911 if the person has collapsed, had a seizure, has trouble breathing or cannot be woken.
Can you eat after taking Zofran? Can you take it with Ativan, Phenergan or Advil?
MedlinePlus says to continue your usual diet unless told otherwise, and the label says food slightly increases how much drug is absorbed. The label’s interaction section names serotonergic drugs (such as SSRIs and SNRIs), tramadol and apomorphine, but it does not list lorazepam (Ativan), promethazine (Phenergan) or ibuprofen (Advil). That is not a clearance: ask a pharmacist before combining medicines, especially with alcohol.
People also ask
Can I take Zofran for a hangover?
Zofran is approved for nausea from chemotherapy, radiotherapy and surgery, not for hangovers. Ask a doctor or pharmacist before using it after drinking. The NIAAA says only time cures a hangover.
Does Zofran interact with alcohol?
The FDA label does not list alcohol among its interactions, but it warns about heart rhythm changes and serotonin syndrome. Check with a pharmacist, especially if you take other medicines.
What helps nausea after drinking?
The NIAAA says no hangover remedy is proven and only time helps. If vomiting comes with confusion, trouble staying awake or slow breathing, call 911: these can be signs of alcohol overdose.
Can you mix Zofran and alcohol?
No official page says you cannot or can. The ondansetron label and MedlinePlus do not mention alcohol; liver problems and age over 75 slow clearance of the drug, so ask a pharmacist.
Can you drink alcohol while taking Zofran or take Zofran while drunk?
We found no official rule. The label does not mention alcohol, and nausea from drinking is outside its approved use. Ask a pharmacist.
Will Zofran help a hangover?
We found no official source saying so. The NIAAA says there is no cure for a hangover other than time.
Can you take 2 Zofran at once?
Only if your prescriber said so. MedlinePlus says not to take more than prescribed or double up after a missed dose; for an overdose call 1-800-222-1222.
Can you eat after taking Zofran?
Yes. MedlinePlus says to continue your usual diet unless your doctor says otherwise, and the label says food slightly increases absorption.
