This information will help you prepare for your Bravo Capsule Test at Memorial Sloan Kettering Cancer Center (MSK).
The 48-hour Bravo Capsule test determines the amount of acid that comes back into your esophagus (food pipe) from your stomach. It can tell your doctor the amount of acid reflux you have and length of time you experience it as you go about your normal activities.
Before Your Procedure
Ask about your medications
You will need to stop taking some medications 1 week before your procedure. Some common examples are:
- Proton pump inhibitors, such as rabeprazole (Aciphex®), omeprazole (Prilosec®), lansoprazole (Prevacid®), pantoprazole (Protonix®), and esomeprazole (Nexium®)
- Histamine2 blockers, such as nizatidine (Axid®), famotidine (Pepcid®), cimetidine (Tagamet®), and ranitidine (Zantac®)
If you take insulin or other medication for diabetes, you may need to change the dose on the day of your procedure. Ask the doctor who prescribes this medicine for you what you should do the day before and the morning of your procedure.
If you have an automated implanted cardioverter-defibrillator (AICD), you will need to get a clearance letter from your cardiologist before your procedure.

Where to go
Your procedure will take place in the Endoscopy Suite at the main hospital, which is located at 1275 York Avenue. Take the M elevator to the 2nd floor.
What to expect
Once you arrive at the hospital, doctors, nurses, and other staff members will ask you to state and spell your name and date of birth many times. This is for your safety. Patients with the same or similar names may be having procedures on the same day.
After changing into a hospital gown, you will meet your nurse. He or she will place an intravenous (IV) catheter into a vein, usually in your hand or arm. At first, you will receive fluids through the IV, but it will be used later to give you anesthesia (medication to make you sleepy). Your nurse will also check your heart rate, breathing, and blood pressure.
Your doctor will explain the procedure to you and answer any questions you have. He or she will ask you to sign a consent form.
When it's time for your procedure, you will be taken to the procedure room and helped onto an exam table. You will receive anesthesia through your IV, which will make you sleepy. You will be attached to equipment to monitor your heart, breathing, and blood pressure. You will also receive oxygen through your nose. Your doctor will place the capsule into your esophagus while you are asleep.
After Your Procedure
In the recovery room
You will wake up in the recovery room. Your nurse will continue to monitor your heart rate, breathing, and blood pressure. Once you are fully awake, your nurse will remove your IV. If you have someone waiting with you, your nurse will explain your discharge instructions to both of you before you go home.
It is important that you eat, drink, work, and exercise as you normally would. However, avoid the following because they will affect your test results:
- Foods high in acid, such as coffee, orange juice, cranberry juice, and soda
- Gum and throat lozenges
- Between-meal snacks
You will be given a diary the day of your procedure. It is important that you keep accurate records in the diary. This will help the doctor decide how best to help you. Be sure to write down the following:
- All of the symptoms you have, such as coughing, heartburn, and burping food into your mouth
- All of the medications you take
- Everything you eat and drink
- The time you eat and drink
- When you lie down
You will be given a receiver to wear on your waistband or belt. Keep the receiver within 3 feet of your body all the times. If it is too far away, it will beep. Do not let the receiver get wet.
You may have some discomfort in your chest after your procedure. You can take acetaminophen (Tylenol®) to relieve this discomfort.
The capsule will pass through your system and come out during a bowel movement, but you might not see it.
Do not have magnetic resonance imaging (MRI) for 30 days after the capsule is placed.
You will need to return the receiver and your diary to your doctor during your follow-up appointment.
