Overview

The NeilMed^® sinus rinse™ is a saline (salt water) nasal wash used to treat rhinitis (inflammation of the lining of the nasal passages) and sinusitis (inflammation of the sinuses).

It works by cleaning mucus, allergens (things that can cause an allergic reaction) and irritants from the nose and sinuses. This can help reduce inflammation and might improve symptoms such as a blocked or runny nose, dry cough, facial pressure, facial pain and loss of smell or taste.

The NeilMed sinus rinse kit contains sachets that are dissolved in water to create a nasal wash solution, along with a squeeze bottle to help administer the solution into your nose effectively. Each sachet contains sodium chloride (salt) and sodium bicarbonate. The solution is isotonic (contains a similar concentration of salt to the human body) and pH neutral (similar pH to the human body). This means it does not irritate your nasal passages or sinuses, or cause burning or stinging.

How to use the NeilMed sinus rinse

Use the rinse as directed by your doctor. For most people, using it 2 times a day is recommended. The kit contains a detailed booklet that includes step-by-step instructions, which should be read carefully before use.

You can also watch a demonstration video, developed by the manufacturers. 

Treatment is usually recommended for 3 months at first, but might be continued long-term if it's helping your symptoms.

Side effects

Saline nasal rinses are generally safe and do not normally cause problems.

Possible side effects include:

• mild ear discomfort while rinsing
• drainage of leftover solution from the nose after use

These can usually be avoided by following the instructions provided in the kit.

You might notice a temporary increase in nasal congestion when you first start using the rinse, but this usually improves with continued use. 

You should not swallow the solution. However, if you do swallow some by accident, this is not harmful as the amount of salt contained in one swallow is low.

How to get a repeat prescription

NeilMed sinus rinse sachets are classed as a medical device rather than a medicine, so they cannot be prescribed on an NHS prescription by your GP.

You will be given your first kit by the hospital but, if you need more sachets, you must buy them online or in a pharmacy. There are different types available, so you should make sure that you buy the isotonic ones.

It is also recommended that the squeeze bottle is replaced every 3 months.

Making your own saline solution

If needed, you can make your own saline nasal wash solution, using this method:

• Measure 1 teaspoon of sea, canning or pickling salt.
• Measure 1/2 teaspoon of baking soda.
• Dissolve them in 500ml (1 pint) of freshly boiled and cooled water.

This can be administered using a nasal irrigation pot (neti pot), which you can buy online.

Any unused solution should be thrown away after use. Always prepare a fresh solution each time.
