GoLYTELY

Primary Uses

GoLYTELY is used to cleanse the bowel before certain diagnostic procedures. It is an osmotic laxative that works by causing watery diarrhea to flush out the intestines. This ensures the colon is empty and clean so that healthcare providers can obtain a clear view of the intestinal lining.

Common procedures that require this type of bowel preparation include:

• Colonoscopy: An internal examination of the large intestine using a camera.
• Barium enema: An X-ray examination of the colon and rectum.
• Other intestinal procedures: Any medical test that requires the gastrointestinal tract to be free of stool and debris.

Purpose of Bowel Cleansing

A thoroughly cleaned colon is necessary for a successful examination. If the bowel is not completely clear, the doctor may miss polyps, tumors, or other abnormalities, and the procedure may need to be repeated. GoLYTELY contains electrolytes to help prevent the loss of essential salts from the body while the medication is clearing the digestive tract.

Mechanism of Action

GoLYTELY is an osmotic laxative containing polyethylene glycol (PEG) 3350. PEG 3350 is a large molecule that the body does not absorb into the bloodstream. When the solution is consumed, it stays within the intestinal tract and uses osmosis to hold water there.

By preventing the colon from absorbing water, the medication increases the volume of liquid in the intestines. This extra fluid softens stool and creates pressure against the walls of the colon, which triggers the muscle contractions needed to produce a bowel movement. This process results in a watery discharge that flushes out the entire digestive tract.

Role of Electrolytes

Because the medication causes a large amount of fluid to pass through the body quickly, it is formulated with specific electrolytes, including sodium sulfate, sodium bicarbonate, sodium chloride, and potassium chloride. These salts are included to help maintain the body's natural balance of minerals and water. This helps prevent dehydration or significant changes in blood chemistry while the bowel is being cleared.

Common Side Effects

The most frequent side effects occur as the medication begins to work and the bowels are cleared. These include:

• Nausea
• Abdominal fullness or bloating
• Stomach cramps
• Vomiting
• Anal irritation

Serious Side Effects

Seek medical attention immediately if you experience any of the following serious symptoms:

• Severe or persistent stomach pain
• Severe bloating or abdominal distension
• Seizures
• Irregular heartbeat or palpitations
• Fainting or lightheadedness
• Bloody stools or rectal bleeding
• Signs of dehydration, such as extreme thirst, dry mouth, or decreased urination
• Difficulty swallowing

Allergic Reactions

Get emergency medical help if you have signs of an allergic reaction:

• Hives or skin rash
• Swelling of the face, lips, tongue, or throat
• Difficulty breathing

Fluid and Electrolyte Imbalances

The use of GoLYTELY can cause significant changes in fluid and electrolyte levels in the body. These shifts may lead to serious medical issues, including abnormal heart rhythms, seizures, and kidney failure. People with pre-existing heart or kidney conditions, or those taking medications that affect electrolytes (such as diuretics), are at an increased risk.

Contraindications

This medication should not be used by individuals with certain gastrointestinal conditions, including:

• Known or suspected bowel obstruction
• Perforation in the wall of the stomach or intestines
• Toxic colitis or toxic megacolon
• Gastric retention (when the stomach empties too slowly)
• Ileus (lack of movement in the intestines)

Seizure Risk

Seizures have been reported in patients using bowel preparation products, even in those without a history of epilepsy. These seizures are typically related to severe electrolyte imbalances, such as low sodium levels in the blood.

Kidney and Heart Health

Caution is advised for patients with impaired kidney function or heart conditions like congestive heart failure or a history of heart rhythm problems (arrhythmias). In some cases, healthcare providers may perform blood tests to monitor electrolyte and kidney function before and after use.

Aspiration and Swallowing Difficulties

Individuals with an impaired gag reflex or other swallowing difficulties may be at risk of aspirating (inhaling) the solution into the lungs. Close monitoring is recommended for these patients during the administration process.

Colonic Mucosal Ulcerations

Bowel prep solutions can sometimes cause inflammation or small sores (ulcerations) in the lining of the colon. This may affect the results of the colonoscopy, particularly in patients with inflammatory bowel disease.

Pregnancy

There is limited information regarding the safety of GoLYTELY during pregnancy. Adequate and well-controlled studies in pregnant women have not been conducted, and animal reproduction studies have also not been performed. It is unknown whether this medication can cause harm to a developing fetus or affect reproductive capacity. Because of these unknowns, healthcare providers typically only recommend GoLYTELY for pregnant individuals if it is clearly necessary.

Breastfeeding

It is not known if the components of GoLYTELY are excreted in human breast milk. Because many drugs can pass into breast milk, caution is advised when using this medication while nursing. If you are breastfeeding, you should consult with your healthcare provider to weigh the potential benefits against any possible risks to the infant before using this bowel preparation solution.

Available Forms

GoLYTELY is provided as a powder for oral solution. It is packaged in a disposable jug that contains the medication in dry form. Before administration, the powder must be reconstituted by adding water to the container to reach the specified fill line.

Packaging and Preparation

The medication is generally available in the following format:

• 4-Liter Jug: A large plastic container containing a combination of polyethylene glycol 3350 and electrolytes, including sodium sulfate, sodium bicarbonate, sodium chloride, and potassium chloride.

The product may be supplied as a regular unflavored powder or with flavor packets that can be added to the solution during the mixing process to improve the taste.

FDA Approval and Indications

GoLYTELY is approved by the U.S. Food and Drug Administration (FDA) as an osmotic laxative. It is specifically indicated for bowel cleansing in adults prior to colonoscopy and barium enema X-ray examinations. The medication works by causing watery diarrhea, which clears the colon so that healthcare providers can accurately examine the intestinal walls.

Regulatory Classification

This medication is available by prescription only. While some polyethylene glycol products are available over-the-counter for the treatment of occasional constipation, GoLYTELY is a high-volume electrolyte solution regulated for use specifically in clinical bowel preparation under the guidance of a healthcare professional.

Safety and Monitoring

The FDA has not issued a Boxed Warning for GoLYTELY, and there is no Risk Evaluation and Mitigation Strategy (REMS) required for its distribution. However, the approved labeling includes important safety information regarding potential fluid and electrolyte shifts. Regulatory guidelines advise against its use in patients with known or suspected bowel obstructions, gastric retention, or bowel perforation.

Mixing the Solution

GoLYTELY comes as a powder in a large container. To prepare it, add lukewarm drinking water to the fill line indicated on the bottle. Cap the bottle and shake it vigorously until all the powder has dissolved. Once mixed, the solution should be refrigerated, though it can be used at room temperature if preferred. Do not add any extra flavorings, sugar, or other ingredients to the solution unless specifically instructed by the manufacturer or your healthcare provider.

Dietary Preparation

To ensure the colon is completely clear, you must follow a strict diet before starting the medication:

• Stop eating solid foods and drinking milk at least several hours before starting the solution, or as directed by your doctor.
• Stick to clear liquids only, such as water, clear broth, plain coffee or tea (no milk or cream), and clear fruit juices without pulp.
• Avoid any liquids that are red or purple, as these can interfere with the results of the procedure.

Taking the Medication

The timing of your doses is critical. Your doctor will provide a specific schedule, which often involves drinking 8 ounces (240 mL) of the solution every 10 minutes. Rapidly drinking each portion is generally more effective than sipping it slowly. You will continue this process until the entire 4 liters are consumed or until your bowel movements are clear and free of solid matter. If you experience severe bloating or abdominal pain, you may need to drink the solution more slowly or wait until the symptoms subside before continuing.

Storage and Handling

The mixed solution must be kept refrigerated and used within 48 hours. Any solution not used within this timeframe should be discarded. Keep the container tightly closed when not in use.
