Also indicated for the symptomatic relief of itch associated with chickenpox. For oral administration only. Do not exceed the stated dose or frequency of dosing. Adults and children 12 years and over: 10ml (4mg) every 4 to 6 hourly. Maximum daily dose: 60ml (24mg) in any 24 hours. Elderly: The elderly are more likely to experience neurological anticholinergic effects. Consideration should be given to using a lower daily dose (e.g. a maximum of 12 mg in any 24 hours). Children aged 6 - 12 years: 5ml (2mg) every 4 to 6 hourly. Maximum daily dose: 30ml (12mg) in any 24 hours. Children aged 2 - 6 years: 2.5ml (1mg) every 4 to 6 hourly.

Piriton Syrup is contra-indicated in patients who are hypersensitive to antihistamines or to any of the syrup ingredients. The anticholinergic properties of chlorphenamine are intensified by monoamine oxidase inhibitors (MAOIs). Piriton Syrup is therefore contra-indicated in patients who have been treated with MAOIs within the last fourteen days.

Piriton Syrup provides fast relief from symptoms of hayfever, skin allergies, food allergies, pet allergies, or nasal allergies. It can also be used to provide itch relief for chickenpox. This syrup can be used for children over 1 year.
