Cough: treating dry cough
Cough suppressants
Cough suppressants are sometimes known as antitussives. Pholcodine and dextromethorphan are 2 over-the-counter cough suppressants that are available from your pharmacist.
Combination products
A number of combination products are available, which combine a cough suppressant with a decongestant or antihistamine or both. Some antihistamines may reduce the urge to cough, and some have sedative effects that may help sleep. However they should not be used primarily for this.
If you have a dry cough, you should avoid taking combination products that contain an expectorant or a decongestant, as these ingredients are useful only when congestion is present. Decongestants such as pseudoephedrine may also cause insomnia and restlessness.
Lozenges
Cough suppressant lozenges have the added advantage of having a longer contact time, but you should check the sugar content. Lozenges may also contain various combinations of other ingredients such as an antiseptic, analgesic, anti-inflammatory or anaesthetic.
Gargling salt water or antiseptic/anti-inflammatory gargle may also provide some relief from a dry cough.
