To stop continuous vomiting, medications called antiemetics are commonly used. Generic options include Ondansetron, Metoclopramide, or Promethazine. However, because continuous vomiting can quickly lead to dehydration, it is very important to consult a doctor before taking any medication. A professional can safely determine the right dose and the underlying cause. In the meantime, once vomiting temporarily pauses, try taking small, frequent sips of water or an oral rehydration solution to stay hydrated. If you experience severe pain, high fever, or cannot keep fluids down for over 12 to 24 hours, please seek medical attention right away.

Because you cannot keep any liquids down, taking oral medications right now will not be effective, as you will likely throw them up before they can work. The safest and most effective step is to be evaluated by a healthcare professional at an urgent care or emergency room. They can safely administer fluids and anti-vomiting medications, such as generic ondansetron, directly through an IV or as a fast-dissolving tablet under the tongue. This will stop the vomiting quickly and prevent dehydration. Please seek medical attention so you can get relief soon.
