Using magnesium citrate before a procedure

• 1). Follow your doctor's directions. Magnesium citrate is often only one part of an entire bowel cleansing that your doctor may have prescribed before your colonoscopy or other procedure. First, read your doctor's directions carefully, and then read the directions on all of the medications your doctor has given you.
  
  
• 2). Buy a flavored version, preferably lemon-lime, and put it in the fridge, as chilled is the easiest way to consume it. It doesn't taste great, and you will be drinking the entire bottle.
  
  
• 3). Drink magnesium citrate on an empty stomach, according to the directions on the bottle or your doctor's directions. Your doctor should tell you when it's best to take it. If your doctor's directions and the directions on the bottle differ, call your doctor or pharmacist. Do not leave the house for the rest of the day or night.
  
  
• 4). Drink a full glass of water. Magnesium citrate works by pulling water into the intestinal tract, so it's important to have enough water in your system to avoid dehydration.
  
  
• 5). Wait and eliminate. Magnesium citrate is a strong laxative and will likely require multiple trips to the bathroom. You may also experience some minor cramping. Keeping hydrated will help with any discomfort. Bowel movements should occur in 30 minutes to six hours.
