What About my Current Medications?
You can take most medications as usual until the day of the EUS examination. Tell your doctor about all medications that you're taking and about any allergies you have to medication. Anticoagulant medications (blood thinners, such as Coumadin or heparin) might need to be adjusted before EUS. Insulin also needs to be adjusted on the day of EUS. Check with your doctor in advance regarding these prescriptions and regarding aspirin and non-steroidal anti-inflammatory (ibuprofen, naproxen, etc.). Check with your doctor about which medications you should take the morning of the EUS examination, and take essential medication with only a small cup of water.
If you have an allergy to latex, you should inform your doctor prior to your test. Patient with latex allergies often require special equipment and might not be able to have an EUS examination.
Do I Need to Take Antibiotics?
Antibiotics aren't generally required before or after EUS examinations. But tell your doctor if you take antibiotics before dental procedures. If your doctor feels you need antibiotics; antibiotics might be ordered during the EUS examination or after the procedure to help prevent an infection. Your doctor might prescribe antibiotics if you're having specialized EUS procedures, such as to drain a fluid collection or a cyst using EUS guidance. Again, tell your doctor about any allergies to medications.
Should I Arrange for Help After the Examination?
For an EUS examination of the upper gastrointestinal tract, your endoscopist might spray your throat with a local anesthetic before the test begins. Most often, you will receive sedatives intravenously to help you relax. You will most likely begin by lying on your left side. After you receive sedatives, your endoscopist will pass the ultrasound endoscope through your mouth, esophagus and stomach into the duodenum. The instrument does not interfere with your ability to breathe. The actual examination generally takes between 15 to 45 minutes. Most patients consider it only slightly uncomfortable, and many fall asleep during it.
An EUS examination of the lower gastrointestinal tract can often be performed safely and comfortably without medications, but you'll receive a sedative. You will start by lying on your left side with your back toward the doctor. Most EUS examinations of the rectum last from 10 to 30 minutes.
What Happens After EUS?
You will be monitored in the recovery area. If you had an upper EUS, your throat might be a little sore. You might feel bloated because of the air and water that were introduced during the examination. You'll be able to eat after you leave the procedure areas, unless you're instructed otherwise.
Your doctor generally can inform you of the results of the procedure that day, but the results of some tests will take several days.

AS THE SEDATION GIVEN WILL NOT ALLOW YOU TO DRIVE FOR 12 HOURS.
