Fasting and Medication Instructions

Fasting and Medication Instructions



Please fast from all food-types for at least 6 hours prior to your admission time. This includes chewing gum, lollies, and mints.

  • If your admission time and surgery is scheduled for the morning, please fast from midnight. 
  • If your admission time is scheduled closer to midday for surgery in the afternoon, you can have a light breakfast. Please ensure that you have finished your meal at least >6 hours prior to your admission time (a light breakfast consists of liquids, 1 egg or cereal or a piece of toast. Do not eat greasy foods such as bacon or sausage). 


You may drink plain water up until 2 hours prior to your procedure – please limit your intake to 250ml per hour. 

You may also drink clear fluids up until2 hours prior -this includes black tea, black coffee, cordial and pulp-free juice. 

NB: Milk, juice (with pulp) and other liquids are classified as food and must be ceased >6 hours prior to your admission time. 

There is to be no food or fluid intake beyond the 2 hour mark prior to your procedure.

Failure to follow these instructions greatly increases the chance of serious adverse complications under anaesthetic and as such, your procedure may be delayed until you are properly fasted or potentially cancelled on the day.


Please take all of your usual medications unless advised differently by your Surgeon or Anaesthetist. Your medications can be taken with a small glass of water.

NB: Special circumstances apply to:

  • Diabetic injectable insulins and oral medications, particularly the SGLT2 Inhibitors: 
      • dapagliflozin (Forxiga, Qtern or Xigduo XR)
      • empagliflozin (Jardiance, Jardiamet or Glyxambi)
  • Anticoagulants / ‘Blood-thinning’ medications

Please discuss these medications directly with your Anaesthetist at least 3 days prior to your procedure as they may need to be changed, ceased or have the dosage altered. 

Any concerns regarding your medications are best clarified with your Anaesthetist by contacting the Strive Anaesthesia rooms on (08) 6158 9997.
