Pharmacist tips for Sutab

pharmacist
  • Sutab can cause symptoms of bloating, nausea, or cramping. Wait until your stomach symptoms are better before drinking more water or taking a second dose.
  • Take Sutab exactly as directed by your healthcare team. If you aren't able to complete the two doses or drink the required amount of water, let your care team know before your colonoscopy. Make sure you plan your two doses accordingly so you can finish them on time.
  • Once you've started taking Sutab, avoid solid foods, dairy products (e.g., milk), and alcohol. These types of food can interfere with your colonoscopy.
  • Avoid eating or drinking anything colored red or purple (e.g., juices or jello), which can be mistaken as blood in the colon during the procedure.
  • Some medications, such as stimulant laxatives and iron supplements, can interact with Sutab or interfere with your colonoscopy. Let your healthcare team know what medications you're taking, including over-the-counter products and supplements, before you start Sutab. Talk with your care team if you have any questions about interactions with this medication. Your healthcare team might ask you to stop taking certain medications within an hour of starting Sutab.
  • After taking Sutab, you might experience frequent diarrhea until your bowels are cleared out. Make sure to stay near a toilet during treatment. The day before your colonoscopy:
  • Make sure to avoid eating foods that are high in fiber or take a long time to digest. Some breakfast options include eggs, white bread, cottage cheese, yogurt, grits, coffee and tea.
  • After breakfast, drink only clear liquids all day and the next day until 2 hours before your procedure. Examples include coffee or tea (without creamer), fruit juices without pulp, jello, water, chicken broth, sports drinks (e.g., Gatorade) and clear soda (e.g., ginger ale). The day of your colonoscopy:
  • Complete your second dose of Sutab 5 to 8 hours before the procedure, and more than 4 hours after the first dose.
  • Don't drive a car or operate machinery after your colonoscopy. Instead, arrange for someone to drive you to and from your appointment.

Common questions about Sutab

Both doses of Sutab contain 12 tablets and they should work at the same rate. If you experience bloating, cramping, or nausea during your dose, make sure to pause or slow down the rate of drinking water until these symptoms go away.

Your healthcare team will instruct you to drink 16 ounces of water as you take each dose of Sutab (12 tablets per dose). After this, they'll ask you to drink an additional 32 ounces of water over the course of one hour. This is to help prevent dehydration. If needed, you can continue to drink water or other clear liquids. Keep in mind that drinking extra water might cause bloating, nausea, and stomach cramping. Make sure to slow down on your fluid intake if you experience stomach side effects. Stop drinking all fluids at least 2 hours (or as directed by your care team) before the colonoscopy.

According to clinical studies, Sutab can stay in your system for 24 to 48 hours after your colonoscopy.

It's important to take Sutab exactly as directed by your healthcare team. Typically, one treatment of Sutab is made up of 2 doses. Usually, your care team will ask you take your first dose the night before the colonoscopy, and the second dose the morning of the colonoscopy. Following the schedule for your bowel preparation allows your care team to see inside your colon better on the day of the procedure. But if you experience bloating or stomach upset after your first dose, they might ask you to hold off on the second dose until you feel better. But if you miss a dose of Sutab, let your care team know right away since they might need to reschedule your appointment.

Sutab cleanses your colon by causing diarrhea. There's limited studies looking into when diarrhea is expected to stop. But most people experience their bowel movements returning to normal within 2 to 3 days after the colonoscopy. If you experience diarrhea for longer than 2 days after your procedure or diarrhea with additional symptoms (fever, bloody stool), let your healthcare team know right away because you might need more medical attention.

Sutab is split into two doses. Typically, your healthcare team will instruct you to take the first dose the evening before your colonoscopy. You should complete the second dose 5 to 8 hours before your procedure and at least 4 hours after your first dose. Each dose takes approximately an hour to complete so make sure you time your doses well.

No, Sutab isn't available OTC. You would need a prescription from your healthcare team in order to get this medication. Sutab is usually prescribed for you in preparation for a colonoscopy.

Sutab and Suprep are both bowel preparations for a colonoscopy. They both require a 2-dose regimen to clean out your colon. While Sutab is available in tablet form, Suprep is only available as an oral solution. In addition, Sutab is only used for adults, but Suprep can be used in adults and children 12 years and older. Discuss with your healthcare team about which option is best for you.

Risks and warnings for Sutab

Sutab can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Serious fluid and electrolyte problems

  • Risk factors: Kidney problems | Not drinking enough fluids | Heart problems

Sutab can cause severe fluid loss (dehydration) and an imbalance in body salts (electrolytes). This can lead to serious health problems, including abnormal heartbeat, seizures, and kidney problems. If you experience a lot of vomiting or signs of dehydration (feeling weak, dark-colored urine, confusion), let your healthcare team know right away. Your care team will order lab work to check your electrolytes and kidney function. Don't take Sutab until your lab work are normal and you're hydrated.

Heart problems

  • Risk factors: History of prolonged QT | Uncontrolled irregular heartbeat | Recent heart attack | Chest pain | Heart failure | Heart muscle problems

In some rare cases, some people who take Sutab can experience irregular heartbeat. Your risk is higher if you have a history of heart problems, such as abnormal heart rhythm, heart attack, chest pain, or heart failure. Let your healthcare team know about your medical conditions before starting this medication. Your care team might ask you to get an electrocardiogram (EKG) before or after your colonoscopy to make sure your heart is not affected by Sutab.

Seizures

  • Risk factors: Changes in electrolyte levels | History of seizures | Taking medications that raise seizure risks | Withdrawal from alcohol or medications belonging to the benzodiazepines class

In some cases, people who take Sutab have experienced seizures and loss of consciousness. This is because Sutab can cause dehydration and electrolyte imbalance, which can both trigger seizure episodes. You can be at risk even if you had no history of seizures. Let your healthcare team know if you take medications that raise your risk of seizures (e.g., amitriptyline), if you experience alcohol withdraw, or if you have a history of low sodium levels.

Kidney problems

  • Risk factors: People over age 65 | Dehydration | History of kidney problems | Use of certain medications (diuretics, ACE-I/ARB, NSAIDS)

Sutab can raise the risk of kidney damage in people who already have problems with their kidneys. It can also raise the risk of kidney damage in people who are taking medications that affect kidney functions, such as diuretics, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers, and nonsteroidal anti-inflammatory drugs (NSAIDs). Make sure to stay hydrated before and after taking Sutab. Your healthcare team might check your kidney health before and after your colonoscopy. Get medical attention right away if you experience symptoms of kidney damage, such as difficulty urinating, swelling in your feet and legs, nausea, vomiting, confusion, and weakness.

Colon damage

  • Risk factors: Inflammatory bowel disease (IBD) | Ulcerative colitis | Taking other laxatives

Sutab might damage your colon, which can lead to hospitalization. Don't take other laxatives while using this medication for colonoscopy. Let your healthcare team know if you have history of stomach ulcers, blockage, or inflammatory bowel disease (IBD) before your procedure.

Serious allergic reactions

Some people have reported serious allergic reactions after taking Sutab. Symptoms included anaphylaxis, trouble breathing, rash, and hives. Get medical help right away if you notice these symptoms.
