For nasal use, 2-3 sprays should be instilled into each nostril twice a daily.
The nasal spray can be used with the patient in the upright position. Sprays are generally unsuitable for young children because of the small size of their nostril.
A treatment course should not normally exceed three to five days, and on no account should it be continued for longer than two weeks because of the risk of developing 'rhinitis medicamentosa'.
