It is safe to treat nausea at home using several measures such as taking enough fluids and making dietary changes, says MedlinePlus. However, the doctor must first identify the cause of nausea before recommending home treatment measures.
For nausea that occurs due to morning sickness, doctors recommend lying down, taking over-the-counter antihistamines, and using scopolamine prescription skin patches to manage morning sickness, says MedlinePlus. There are many other causes of nausea including allergies, migraines, leaking of stomach contents, medical treatments and bowel infections. Nausea that occurs alongside other symptoms, such as fainting, blurred vision, chest pain, severe abdominal pain or confusion, requires medical attention, notes Mayo Clinic.
