    Home Care
    When the cause of nausea and vomiting is known, it is important to treat the underlying disorder. Whatever the cause, it is important for the person who has vomited a great deal to take in as much fluid as possible without upsetting the stomach any further. Sip clear fluids such as water, ginger ale, fruit juices, or Gatorade. Don’t drink too much at any one time, and work slowly back to a normal diet. Infants who are vomiting repeatedly should be seen be a physician. DO NOT GIVE INFANTS WATER, as this may lead to electrolyte imbalances. Instead, hydration should be maintained by using 1/2 strength formula or oral rehydration solutions such as Pedialyte given in frequent small amounts. Start with 1 teaspoon every 5 minutes and slowly increase the amount. Once full feed amounts are reached and the infant has gone 8 hours without vomiting, return to regular feeding. There is currently no treatment that has been approved by the FDA for morning sickness in pregnant women. Treatment for motion sickness:
  • Lying down can often help.
  • Antihistamines (such as cyclizine, meclizine, or Marezine), which are available over the counter, may help.
  • Scopolamine skin patches (such as Transderm Scop) require a prescription and are useful for extended trips (such as an ocean voyage). In order to prevent the onset of motion sickness, the scopolamine patch should be placed 4 to 12 hours before setting sail. Although scopolamine is effective, it may produce dry mouth,
  • blurred vision , and some drowsiness . Scopolamine is for adults only. It should not be given to children.
