1. What Piriton Syrup does


Piriton Syrup is used to treat the allergic symptoms of hayfever and other allergies.
The active ingredient is chlorphenamine maleate, an antihistamine which can help
to relieve the symptoms of some allergies and itchy skin rashes. It can be used to
treat the itchiness, redness, swelling, tenderness and irritation that can be caused
• hayfever and other allergies e.g. pet, house dust mite
and mould spore allergies
• nettle rash and hives
• skin allergies and dermatitis
• prickly heat and heat rash
• reactions to food, food additives or medicines
• insect bites and stings
• the itchy rash of chickenpox.

• if you have ever had an allergic reaction to antihistamines or any of
the ingredients (listed in Section 6)
• if you have taken monoamine oxidase inhibitors (MAOIs) prescribed
for depression in the last two weeks
• if you are taking other medicines containing antihistamines, including
products for the relief of colds and coughs.

Take special care with Piriton Syrup
• Talk to your doctor before you take this syrup if you have very high
blood pressure, heart disease, epilepsy, glaucoma, enlarged prostate,
liver disease, kidney disease, bronchitis, asthma or bronchiectasis.
• Avoid drinking alcohol with this medicine.
• Do not drive or operate machinery if the syrup makes you feel drowsy, dizzy
or if you experience blurred vision.
• Piriton Syrup contains 6.3% v/v ethanol (alcohol), similar to 6.3 ml beer

from alcoholism. This should also be considered if you are pregnant or
breast feeding, in children and high-risk groups such as patients with
liver disease or epilepsy.
• Clean your teeth regularly. The syrup contains sucrose and long term
use could increase the risk of tooth decay.
• If you have been told by your doctor that you have an intolerance to
some sugars, contact your doctor before using Piriton Syrup.
• Piriton Syrup contains 2.36 g of sucrose per 5 ml. This should be taken
