Capsule Patency Prep

Capsule Patency Prep Explained

The patency capsule is an ingestible and dissolvable capsule intended to ensure that things move normally through the GI tract (i.e., it is “patent” or open). It is typically used to determine if it is safe to proceed to a capsule endoscopy test (a procedure that is used to look at your small intestine for conditions such as chronic gastrointestinal bleeding, anemia, small bowel polyps, and suspected Crohn’s disease). An x-ray will be performed 24 hours following ingestion of you capsule to ensure that it has moved through the entire small bowel.

Important Things to Know

  • Continue all aspirin and anti-inflammatory medications including ibuprofen, Motrin, Aleve, naproxen, Naprosyn, sulindac, piroxicam, Feldene, indomethacin, diclofenac, and Voltaren. Tylenol (acetaminophen) is also safe to continue.
  • If you are diabetic and use insulin, please contact our office for insulin instructions.
  • PLEASE call our office if you have any questions about which medications that you should or should not take.

Timing & Schedule

Preparation follows a short, structured timeline leading up to the day of your test. You’ll make brief dietary adjustments beforehand, fast overnight, swallow the capsule during your visit, and complete follow-up imaging afterward if needed. Detailed instructions and exact timing are provided below.

Instructions:
Step 1.
Day Before Your Procedure
  • You may eat a normal breakfast and lunch completed by noon 12 PM followed by a clear liquid diet the rest of the day. Please avoid red liquids. Some examples of clear liquids are apple juice, soda, coffee, tea, beef or chicken broth, Jell-O, Gatorade, or plain water.
  • DO NOT take anything by mouth after 11:59 PM – this is very important.
  • You may take your usual prescribed medications with small sips of water.
Step 2.
Day of Your Procedure
  • You should not eat or drink anything prior to your appointment.
  • Please check in at the Boise Endoscopy Center at 7:15 am on your appointment date.
  • After you check in you will meet with a nurse who will go over your instructions, obtain your consent and give you the small patency capsule to swallow.
Step 3.
After Swallowing the Capsule
  • After you swallow the patency capsule you may leave the endoscopy center and return to your normal activities.
  • You may start drinking liquids two hours after swallowing the capsule and you may eat four hours after swallowing the capsule.
  • Your physician will order an abdominal x-ray to be taken 24 hours after the patency capsule has been swallowed.
  • A nurse will contact you regarding the results of the abdominal x-ray once your physician has reviewed the x-ray result.
