General Product Description

A natural way to help relieve congestion, FESS® Nasal and Sinus Extra Strenght Hypertonic Wash is a non-medicated nasal and sinus wash. FESS® Nasal and Sinus Wash Extra Strength consists of 24 pre-mixed dry powder sachets. When mixed with warm water, each 6.3 g sachet will produce 200mL of alkaline buffered, mild hypertonic saline wash.

This deep cleansing, non-medicated hypertonic saline wash helps relieve nasal congestion and sinusitis.

A hypertonic solution is ‘saltier’ than regular saline to gently draw liquid out of the sinuses and help break down this mucus. The higher salt concentration also helps with severe swelling and mucus build up.


It helps relieve nasal and sinus congestion due to colds, sinusitis, rhinitis and allergies by irrigating the nasal and sinus cavities with a large volume of saline solution. This helps wash away excess mucus, allergens and pollutants. Frequent sufferers of rhinitis and sinusitis may find that regular use of FESS Sinu-Cleanse® may help decrease the use of medicated products.


Post-Operative Nasal Care:
Nasal surgery can result in inflammation of the nasal and sinus cavities. After nasal surgery there is also a tendency for crusts of dried blood and mucus to irritate the sinus passages and block mucus drainage. Regular use of FESS® Nasal and Sinus Wash post operatively will help clear the nasal and sinus cavities of dried blood and mucus. Your ENT specialist will advise and instruct in the use of this product in the post-operative period.

Directions for Use

Please read instructions for use carefully. Before commencing to use FESS® Nasal and Sinus Wash you will need to boil 200 mL of water then allow it to cool until luke warm. Do not use with boiling hot water.

  1. Empty contents of one sachet into the FESS® Nasal and Sinus Wash squeeze bottle.
  2. Pour previously boiled luke warm water into the bottle to the line marked ‘FULL’ .
  3. Place cap and tube onto the bottle and screw on tightly. Place finger over opening of cap and shake the bottle gently until the powder dissolves.
  4. Lean or bend over a basin and place the cap gently inside the right nostril ensuring the tip is pointed towards the back of your head. Keeping your mouth open, gently squeeze the bottle in a pulsing action. Whenever the soft squeeze bottle needs to fill with air, remove it from the nose before you release your hand pressure. This prevents “suck back” and helps to keep the remaining solution clean.
  5. Allow approximately half of the solution to wash through the nasal passages and sinus cavity and come out of the left nostril
  6. A small amount of the solution may enter your throat. This is not harmful.
  7. Using the remaining solution, repeat this process in your left nostril.
  8. If necessary, blow your nose when you have finished.
  9. Discard any remaining solution you do not intend using within the next 2 hours.
  10. Wash bottle, cap and tube thoroughly after each use and allow it to drip-dry.
  11. For best results use FESS® Nasal and Sinus Wash once or twice daily or as directed by your doctor or specialist. This bottle is a mixing bottle for your convenience of use only. It is not a measuring device.



FESS Sinu-Cleanse® should not be taken orally and should be kept out of reach of children. Do not use if your nasal passages are completely blocked or if you have an ear infection. Discontinue use if wash causes pain or excessive irritation. If symptoms are not relieved within 2 days, consult your healthcare professional. The FESS Sinu-Cleanse® Squeeze Bottle should not be used for any other purpose. It should be discarded if damaged or discoloured in any way. 


The sachets contain the solution in dry powder form. Keep in a cool dry place below 30°C. Keep out of reach of children
