When vomiting will not stop and fluids will not stay down, waiting it out at home stops being the safe option. ER of Mesquite – Emergency Room is the stomach flu emergency room open 24/7 at 1080 E Cartwright Rd Ste 100, with IV fluids, anti-nausea medication, and lab testing on-site. Walk in now, no appointment needed.
Go to the ER for vomiting that lasts more than 24 hours, includes blood, comes with severe abdominal pain, or is paired with dehydration signs like dizziness, dry mouth, a rapid heartbeat, or noticeably reduced urination. Vomiting after a head injury, or alongside high fever and confusion, also needs same-day evaluation rather than home management.
If you cannot keep even small sips of water down for several hours, that alone is a reason to come in. Persistent vomiting sometimes signals something beyond a simple virus, our abdominal pain page covers when stomach pain itself is the emergency.

Severe stomach flu dehydration shows up as a dry mouth and lips, dizziness or lightheadedness when standing, dark yellow or minimal urine, sunken eyes, rapid heartbeat, and unusual fatigue or confusion. Dehydration can progress quickly in young children and older adults, so these signs deserve prompt attention rather than a wait-and-see approach.
Vomiting that will not stop despite rest and small sips of fluid is a can’t-stop-vomiting emergency once it prevents you from staying hydrated. This matters most for infants, young children, older adults, and anyone with diabetes, since dehydration and blood sugar swings can escalate fast. Our diabetic emergency page covers what to do if vomiting occurs alongside high or low blood sugar.
IV fluids for the stomach flu work faster than anything you can drink, restoring hydration directly while your stomach settles. Alongside IV fluids, we run on-site lab testing to check your electrolytes and rule out other causes, then treat nausea with anti-nausea medication so you can keep fluids down again.
As a freestanding emergency room, your visit follows a clear path: you are seen quickly by a board-certified ER physician, we assess your hydration and run labs to find the cause, we treat you with IV fluids and medication on-site, and if your condition needs hospital admission for ongoing care, we coordinate that transfer.

Vomiting is a warning sign when it includes blood, comes with severe or localized abdominal pain, follows a head injury, or occurs with high fever, confusion, or inability to keep any fluids down.

The stomach flu is a viral infection that usually causes gradual nausea and diarrhea over a day or two. Food poisoning often causes sudden, severe vomiting within hours of eating contaminated food.
The stomach flu typically lasts one to three days for adults, though symptoms can linger up to a week. Vomiting or diarrhea beyond several days warrants medical evaluation.
