I am due for a colonoscopy procedure in two days! Dr. has prescribed Fleet Phospho Soda, but the Clinic's Pharmacist has given me "Fleet Enema" to open & use for cleansing (2 doses of 45ML within 12 hours)? Is the formula same and oral administration allowed? I also take Coversyl 5ML for hypertension. Isn't the sodium in fleet enema counterindicated? Yousef Male, 56-year-old in UAE. Your earliest response appreciated!
