What To Expect


What to Expect During Your Colonoscopy

  • During a colonoscopy, your doctor will very carefully put a thin, flexible tube with a lighted fiber optic camera, called a colonoscope, into your rectum and colon. The colonoscope sends pictures of the inside of your colon to a video screen so your doctor can check for polyps (abnormal growths) or colon cancer. If your doctor does see a polyp, it can be removed during your colonoscopy.

  • You will have an IV placed in a vein in your hand or arm so you can be given medicines and fluids. Right before the test begins, your doctor will give you a mild sedative to help make you as comfortable as possible. As you lie on your side, your doctor will slowly and gently put the colonoscope into your rectum and up through your colon. You may feel some pressure, bloating, or cramping during the test.

  • After your test, you will have to rest for a while until the effects of the medicine wear off. While you are resting, your doctor will talk to you about the results of your test and whether any polyps were removed. If a biopsy was performed you can expect to get the results in a few days.

  • Do not drive yourself home after your test. Ask a loved one or friend to go with you on the day of your exam.

What to Expect with SUPREP®BOWEL PREP KIT

Be sure to follow your doctor’s instructions and carefully read the information that comes with SUPREP® BOWEL PREP KIT. Your doctor will tell you when it is time to begin taking SUPREP® BOWEL PREP KIT.

SUPREP is a low-volume bowel preparation that is taken as a split-dose regimen. A split-dose regimen means that you take two 6-ounce bottles of SUPREP® BOWEL PREP KIT. The first 6-ounce bottle is taken the evening before your colonoscopy and the second 6-ounce bottle is taken the morning of your colonoscopy.

After taking your first medicinal dose, you must drink two (2) more 16-ounce containers of water over the next hour. Upon taking the second medicinal dose, it is important to again drink two (2) 16-ounce containers of water over the next hour.

In clinical studies, the most common side effects that people experienced with SUPREP® BOWEL PREP KIT were overall discomfort, abdominal distention, abdominal pain, nausea, vomiting and headache. Call your doctor if you have any questions about taking SUPREP® BOWEL PREP KIT.


Signs You’re Ready for Your Colonoscopy3

Colonoscopies are imperative for detecting abnormalities within the colon, and being adequately prepped for yours is crucial to a successful screening. It can be hard to know when your colon is clean. Here are some ways to know that you’re ready for your procedure:

  • 1. Your stool is clear yellow liquid without dark particles.

  • 2. Your stool comes out like an open tap.

  • 3. You feel like having a bowel movement but nothing comes out.

SUPREP® Bowel Prep Kit (sodium sulfate, potassium sulfate and magnesium sulfate) Oral Solution is an osmotic laxative indicated for cleansing of the colon as a preparation for colonoscopy in adults. Most common adverse reactions (>2%) are overall discomfort, abdominal distention, abdominal pain, nausea, vomiting and headache.

Use is contraindicated in the following conditions: gastrointestinal (GI) obstruction, bowel perforation, toxic colitis and toxic megacolon, gastric retention, ileus, known allergies to components of the kit. Use caution when prescribing for patients with a history of seizures, arrhythmias, impaired gag reflex, regurgitation or aspiration, severe active ulcerative colitis, impaired renal function or patients taking medications that may affect renal function or electrolytes. Use can cause temporary elevations in uric acid. Uric acid fluctuations in patients with gout may precipitate an acute flare. Administration of osmotic laxative products may produce mucosal aphthous ulcerations, and there have been reports of more serious cases of ischemic colitis requiring hospitalization. Patients with impaired water handling who experience severe vomiting should be closely monitored including measurement of electrolytes. Advise all patients to hydrate adequately before, during, and after use. Each bottle must be diluted with water to a final volume of 16 ounces and ingestion of additional water as recommended is important to patient tolerance.
