Buy Piriton Allergy

Piriton Allergy is a treatment that relieves the symptoms associated with hay fever and other allergies. Piriton Allergy is a drowsy antihistamine.

 

How Piriton Allergy works

Piriton Allergy contains the active ingredient chlorphenamine maleate. Chlorphenamine maleate is an antihistamine which treats itching, redness, swelling and irritation caused by an allergic reaction. 

Antihistamines work by blocking the effects of histamine, a substance that your body produces when it comes into contact with something you’re allergic to.

Always take Piriton Allergy exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. 

Swallow the tablet whole with water.

 

For children over 12 years old and adults: 

 

Take 1 tablet every 4-6 hours as needed. Do not take more than 6 tablets in 24 hours.

 

For children 6-12 years old:

 

Give your child half a tablet every 4-6 hours as needed. Do not give your child more than 6 half tablets in 24 hours.
