About Pico-Salax

Overview

Pico-Salax is a prescription bowel-cleansing medicine containing sodium picosulfate, magnesium oxide and citric acid. It is used to clear the colon before a colonoscopy in adults and children aged 9 years and older. Sodium picosulfate stimulates movement in the colon, while magnesium oxide and citric acid combine to form magnesium citrate, which keeps water in the gut to help clear the bowel.

What it treats

- Cleansing the colon before a colonoscopy in adults and children aged 9 years and older.

Safety information

Side effects

Common side effects in adults include nausea, headache, high magnesium levels in the blood, abdominal pain, dehydration and dizziness. In children aged 9 to 16 years, common side effects include nausea, vomiting and abdominal pain. Contact a doctor promptly for serious side effects, including fluid loss or changes in blood salt levels, kidney problems, irregular heartbeats, seizures or fainting. Fainting can lead to falls, head injuries and fractures. Other serious risks include ulcers in the bowel lining, inflammation of the colon due to reduced blood flow, and aspiration (fluid entering the airways).

When to call your doctor

- Seek medical attention immediately if you have a seizure. - Seek medical attention immediately if you faint, especially if you fall or are injured. - Seek medical attention immediately if you notice an irregular heartbeat.

If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.

Before taking this medicine

Do not take Pico-Salax if you have: • Severe kidney impairment (creatinine clearance below 30 mL/minute), because magnesium may build up in the body. • A blockage in the digestive tract or ileus (when the bowel stops moving normally). • A hole or tear in the bowel. • Toxic colitis or toxic megacolon. • Gastric retention (when stomach contents do not empty normally). • An allergy to any of its ingredients. A suspected bowel blockage or perforation must be ruled out before use. Extra caution is needed if you have kidney impairment or take medicines that affect kidney function. Fluid and electrolyte disturbances can lead to abnormal heart rhythms, seizures or kidney problems. Adequate hydration is important, and your clinician may review your medicines and arrange blood tests before and after use. Fainting has been reported and can cause falls, head injuries and fractures. The medicine may also cause ulcers in the bowel lining, which should be considered when interpreting colonoscopy findings in people with known or suspected inflammatory bowel disease. People at risk of inhaling swallowed material into their airways need observation during administration.

Interactions

Tell your doctor about the medicines you take. Some medicines can increase the risks associated with changes in fluid and electrolyte levels during treatment.
