The strength is stated as the percentage w/v of Sodium Chloride. The label states that solutions containing visible solid particles must not be used. When the preparation is intended for intravenous infusion, the label states the approximate concentrations, in millimoles per litre, of the sodium ions and the chloride ions. For a preparation containing 0.9% w/v of Sodium Chloride the concentration of each ion is stated as 150 millimoles per litre.
