When to seek medical help Seek immediate medical help if your nausea is accompanied by heart attack symptoms. Heart attack symptoms include crushing chest pain, an intense headache, jaw pain, sweating, or pain in your left arm. You should also seek emergency attention if you experience nausea combined with a severe headache, stiff neck, difficulty breathing, or confusion. Seek medical help if you suspect that you’ve ingested a poisonous substance or if you’re dehydrated. See your physician if nausea has left you unable to eat or drink for more than 12 hours. You should also see your physician if your nausea doesn’t subside within 24 hours of trying over-the-counter interventions. Always seek medical attention if you’re concerned you may be experiencing a medical emergency. How is nausea treated? Treatment for nausea depends on the cause. Sitting in the front seat of a car, for example, may relieve motion sickness. Motion sickness can also be helped with medications such as dimenhydrinate (Dramamine), an antihistamine, or by applying a scopolamine patch to relieve seasickness. Taking medications to address nausea’s underlying cause can help as well. Examples include stomachacid reducers for GERD or pain-relieving medications for intense headaches. Keeping hydrated can help to minimize dehydration after your nausea subsides. This includes taking small, frequent sips of clear liquids, such as water or an electrolyte-containing beverage. When you begin to reintroduce food, it’s helpful to stick to the BRAT diet (bananas, rice, applesauce, and toast) until your stomach is more settled.
