Medications: Which to take, which to stop

Fasting and Medications

Most medications should be continued before, during and after operations and anaesthesia. Take them at or near the usual time with a sip of water, at least two (2) hours before admission to hospital or 3-4 hours before your expected operation time. Exceptions are:

    • Diabetes medications (tablets and injections) should usually be stopped while fasting, to minimise the risk of a ‘hypo’ (which is more dangerous than high sugar levels). Please make a consultation for specific advice for your situation.
    • Blood thinners are usually stopped (e.g. aspirin, anti-inflammatories, warfarin, anti-platelet agents such as clopidogrel). You may need to consult with your cardiologist prior, as sometimes the risk of clotting (e.g. cardiac stents) outweighs the risk of bleeding during the operation.

Dex drink

Dex is a drink filled with complex carbohydrates that optimise your body functions. It is medically formulated, safe to have before your anaesthetic by keeping your body nourished and hydrated, eliminating the usual hunger and thirst that precedes surgery.

Also, Dex drink prevents muscle breakdown that occurs with fasting, helping your body repair itself as soon as surgery finishes, and reducing the likelihood of nausea and infection after your operation. It is fructose-free, sucrose-free and has no artificial flavours or colours. It is an energy-dense liquid meal that meets the strict fasting guidelines, and it is suitable for use before surgery, gastroscopy and colonoscopy.


Smoking should be stopped at least 24 hours prior to reducing the risk of wound and chest infection.


There are risks associated with anaesthesia and surgery. Fortunately, significant risks are very rare. Australia is quoted as one of the safest countries in the world for anaesthesia. Some risks to consider are listed below. Please discuss any concerns that you may have at your consultation.

Risks increase with obesity, smoking, co-existing medical conditions and complex surgery.

Risks include:

      • Infrequent (<10%): nausea, vomiting, sore throat, bruising/ pain at injection, muscle aches, headache, dizzy
      • Rare risks (<1%): breathing difficulty, nerve injury, allergy, teeth/ lip/ tongue injury, infection and blood clots
      • Extremely rare (<0.1%): awareness, eye injury, brain/ spinal cord injury, heart attack, lung/ liver/ kidney damage
