Migraine nausea and vomiting

Nausea and vomiting are common during migraine attacks. They can be disabling on their own and can make it difficult to keep down water or oral medication.

For some people, nausea is the symptom that makes an attack unmanageable. Treating pain alone may not be enough if vomiting prevents medication, fluids, food, and sleep.

Why nausea matters

If vomiting happens early, pills may not stay down long enough to work. Ask your clinician whether you need an anti-nausea medicine, a non-oral acute option, or a rescue plan for attacks with vomiting.

What may help

Rest in a quiet dark room, sip fluids slowly if possible, avoid strong smells, and follow your medication plan. Some people tolerate small sips of oral rehydration drink better than plain water during nausea.

What to track

Record whether nausea started before pain, after pain, or after medication. Note vomiting, fluids tolerated, medication timing, whether pills stayed down, and whether nausea caused urgent care or missed activities.

Medication questions to ask

Ask whether you should treat nausea early, whether you need a non-oral rescue medicine, what to do if you vomit after a dose, and when dehydration risk means urgent care.

When to get help

Seek urgent care if vomiting prevents fluids, symptoms are different from usual, headache is sudden and severe, or there are neurologic symptoms, fever with stiff neck, confusion, seizure, or signs of dehydration.
