The following principle applies:
In view of the wide range of nebuliser solutions available to treat the different types of airway diseases, we are unable to make any specific recommendation here. Please always seek medical advice about the medication you should use. Your doctor is familiar with the diagnosis made for you and will select the right drugs and dosage for you. Your local pharmacy will also be happy to help with any questions about medication.
Isotonic saline inhalation solutions (e.g. PARI NaCl inhalation solution) moisten the mucous membranes of the airways and are therefore found by patients to be very agreeable. They can be used as a preventative measure or to relieve symptoms of the common cold as well as serving as a carrier solution for drugs.
