Warnings Adults and children aged 12 years and over should use two to three sprays in each nostril up to four times a day. Allow at least four hours between applications. Don't use more than four applications in 24 hours. Before using the spray for the first time it needs to be primed. To do this, remove the protective cap from the nozzle, hold the bottle upright and press the pump down firmly several times (spray into a tissue). The spray should also be primed in this way if you have not used it for more than a week.
