Question 1

What format of saline solution should I choose for a baby?

Accepted Answer

The 5 ml single-dose unit is the standard format for infant nasal rinsing and eye care. Sterile and for single use, it eliminates any risk of contamination between uses.

Question 2

Is single-dose saline solution of higher quality than the bottled kind?

Accepted Answer

No. The solution is identical — 0.9 % sodium chloride in sterile solution. The only difference is the packaging and therefore the guarantee of sterility at the time of use.

Question 3

Should saline solution be kept in the refrigerator?

Accepted Answer

No. Storage is at room temperature, preferably below 25 °C. Cold does not improve the conservation and the manufacturers do not recommend it.

Question 4

How long can an open bottle of saline solution be kept?

Accepted Answer

The duration depends on the packaging and is stated in the manufacturer's leaflet, which is authoritative. In all cases, close the bottle after each use, avoid any contact of the tip with the skin or a wound, and discard the product if the solution becomes cloudy.

Question 5

What is the price difference between single-dose and large format?

Accepted Answer

Around a factor of five per millilitre, according to observed public prices. The single dose is between 6 and 10 cents per millilitre, compared to 1 to 2 cents for a 250 ml bottle. The difference is explained by the cost of individual packaging, not by the formulation.
