Why is this medication prescribed?

Before a colonoscopy, which is an examination of the colon’s interior to check for colon cancer and other abnormalities in adults and children 12 years of age and older, the colon is emptied to allow the doctor a clear view of the colon’s walls. This procedure involves using magnesium sulfate, potassium sulfate, and sodium sulfate. Osmotic laxatives, which include magnesium, potassium, and sodium sulfates, are a group of drugs. In order to get the stool out of the colon, it works by generating watery diarrhea.

How should this medicine be used?

Magnesium sulfate, potassium sulfate, and sodium sulfate are available as tablets (Sutab®) and solutions (liquid; Suprep®). Typically, the first dose is given the evening before the colonoscopy, and the second dose is taken the following morning. When exactly to take your medication will be specified by your doctor. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Follow the manufacturer’s instructions when taking sodium, potassium, and magnesium sulfates. Never take more or less of it than your doctor has advised.

You must start abstaining from solid meals and milk the day before your colonoscopy in order to get ready for the procedure. At this period, you should only consume clear drinks. Water, light-colored fruit juice without pulp, clear broth, coffee or tea without milk, flavored gelatin, popsicles, and soft drinks are a few examples of clear liquids. Avoid consuming alcoholic beverages and any red or purple liquids. If you have any concerns about what liquids you may consume prior to your colonoscopy, ask your doctor. If you have difficulties drinking clear drinks, let your doctor know.

You must mix the drug solution (Suprep®) with water just before ingesting it if you’re taking the solution. There is a higher likelihood that you will suffer unpleasant or harmful side effects if you consume the solution without mixing it with water. To prepare each dose of your medication, fill the dosing container that was provided with the medication with water until it reaches the line (16 ounces, 480 mL or 12 ounces, 300 mL) that is marked on the cup. This is done by pouring the contents of one bottle of magnesium sulfate, potassium sulfate, and sodium sulfate solution into the container. Immediately consume the entire combination. The night before your colonoscopy, you will take your first dose. After taking this dose, you must consume two containers either 16 ounces, 480 milliliters, or 12 ounces, 300 milliliters of water within the hour before going to bed. The morning before your colonoscopy is scheduled, you will take your second dose. In the hour following the second dose, you must consume two containers (16 ounces, 480 mL, or 12 ounces, 300 mL) of water, but you must finish all the liquids at least two hours before your colonoscopy.

Each dose consists of 12 tablets if you’re using Sutab® tablets. The night before your colonoscopy is scheduled, you will take your first dose (12 tablets), and the morning of your colonoscopy is when you will take your second dose (12 tablets). You must add water to the given container for each dose until it reaches the line (16 ounces, 480 mL) printed on the cup. Each tablet should be taken with a sip of water, and the cup’s contents should be consumed in 15 to 20 minutes. You should drink one 16-ounce container of water over the course of 30 minutes following the administration of a dose (12 tablets) and another 16-ounce container of water over the course of 30 minutes following the consumption of the second container of water. You must consume all the beverages at least two hours prior to your colonoscopy after taking the second dose (12 pills).

During your therapy with magnesium sulfate, potassium sulfate, and sodium sulfate, you will have a lot of bowel movements. From the moment you take your first dose of the medication until the day of your colonoscopy appointment, make sure to stay close to a bathroom. Inquire with your doctor about any comfort measures you can use at this time.

When you start taking this drug, your doctor or pharmacist will give you the patient information leaflet (Medication Guide) from the manufacturer. If you have any questions, carefully read the material and contact your doctor or pharmacist. The Medication Guide is also available on the manufacturer’s website or the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm).

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature.

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilizing a medicine take-back program is the easiest approach to get rid of your medication. To find out about take-back programs in your area, speak with your pharmacist or the garbage/recycling department in your city.
