FAQ’s on Colonoscopies and HalfLytely

What is the HalfLytely® and Bisacodyl Tablets Bowel Prep Kit?
This product is a prescription medicine called a bowel preparation. It is an effective way to clean out your colon (intestines) before your colonoscopy test.

How does it work?
After you take this product, it goes through your intestines and causes you to have a liquid stool (bowel movement). This cleans the body waste out of your colon so your doctor can clearly see the inside of your intestines.

When do I take it?
The HalfLytely® and Bisacodyl Tablets Bowel Prep Kit should be used the day before your test. Your doctor will tell you when it is time to begin.

How do I use the HalfLytely® and Bisacodyl Tablets Bowel Prep Kit?
This product should be used the day before your test. Your doctor will tell you when it is time to begin. It is very important for you to FOLLOW ALL THE STEPS COMPLETELY.

REMEMBER: DO NOT eat food or drink milk on the day of the prep (drink clear fluids only). If you have questions about using the HalfLytely® and Bisacodyl Tablets Bowel Prep Kit, be sure to ask your doctor.

Step 1: TAKE BOTH TABLETS

Take BOTH bisacodyl delayed-release tablets with water. Do NOT chew or crush. Do not take the bisacodyl tablets within 1 hour of taking an antacid.

Step 2: MIX SOLUTION

Add drinking water to top of line on bottle. Cap the bottle and shake to dissolve the powder. The mixed solution will be clear and colorless. The solution may be refrigerated.  The solution should be used within 48 hours of reconstitution.  No additional ingredients (other than flavor packs provided) should be added to the solution. 

Step 3: WAIT FOR A BOWEL MOVEMENT

After a bowel movement occurs (usually in 1 to 6 hours), begin to drink the solution. Even if a bowel movement does not occur within 6 hours, begin to drink the solution.

Step 4: DRINK ALL THE SOLUTION

Drink 1 (8 oz) glass every 10 minutes (about 8 glasses). Drink each glass quickly rather than drinking small amounts continuously. A watery bowel movement should begin in approximately 1 hour. Be sure to drink ALL the solution.

You will still have loose bowel movements for about 1 to 2 hours after you finish drinking the solution.

 


HalfLytely and Bisacodyl Tablets Bowel Prep Kit is a gastrointestinal lavage indicated for cleansing of the colon as a preparation for colonoscopy in adults. Most common adverse reactions (<3%) are abdominal pain/cramping, nausea, vomiting and headache. Use is contraindicated in the following conditions: known allergies to polyethylene glycol or other components of the kit, gastrointestinal (GI) obstruction, bowel perforation, toxic colitis, toxic megacolon.

Use with caution in patients using concomitant medications (such as diuretics) that increase the risk of electrolyte abnormality, patients with known or suspected hyponatremia, patients with severe ulcerative colitis, ileus or gastric retention. There have been reports of ischemic colitis in patients with use of HalfLytely and 20 mg Bisacodyl Tablets Bowel Prep Kit. However, a causal relationship has not been established. If patients develop severe abdominal pain or rectal bleeding, patients should be evaluated as soon as possible. Patients with impaired water handling who experience severe vomiting should be closely monitored including measurement of electrolytes. Hives and skin rashes have been reported with PEG-based products which are suggestive of an allergic reaction.
