Must I do anything special after the test is over?
  • You are usually watched for 30 minutes or more after this test. Typically, you can go home after the sedation wears off, which takes about an hour or two. Follow the precautions for sedation. You can drink clear fluids when your gag reflex returns, which can take two to four hours. Avoid eating solid foods for 24 hours. It's important to call your doctor if you experience dizziness, chest pain, abdominal pain, back pain, difficulty or pain with swallowing, fever, black-colored or tarry stools, or vomiting of material that looks like coffee grounds. The last two symptoms can be signs of internal bleeding.
