Piriton Allergy Syrup - 150ml


Checked By

What is Piriton Allergy Syrup?

Piriton Allergy Syrup is an effective treatment for a number of different allergy types, including hay fever, food, pet, dust mite, skin, and mould. Another benefit of this syrup is that it can also be used to treat the rash produced when affected by chickenpox.

The active ingredient in Piriton Allergy Syrup is chlorphenamine maleate. This is a type of antihistamine that works against the symptoms produced by the allergy.

What is an antihistamine?

An antihistamine is a type of medicine that is designed to treat the effects of allergies. Antihistamines can also be used to treat motion sickness as well as insomnia. There are two types of antihistamine, first-generation and second-generation. The main difference is that the first-generation antihistamines will make you drowsy when using them, which is why they are used to treat a lack of sleep. The active ingredient in this syrup, chlorphenamine, is a first-generation antihistamine and can make you feel drowsy when you use it. 

Who is Piriton Allergy Syrup suitable for?

Piriton Allergy Syrup is suitable for children aged from 1 year and above, as well as adults. This syrup is not suitable for anyone who is allergic to any of the ingredients contained in the syrup.

If you are already taking a form of medication, or are pregnant or breastfeeding, then consult your doctor before taking this syrup.

How much Piriton syrup should I take?

The dosage recommended of Piriton syrup depends on the age of the user. For 1-2-year-olds, the recommended dosage is one 2.5ml spoonful twice a day. For 2-6-year-olds, the recommended dosage is one 2.5ml spoonful every 4-6 hours. For 6-12-year-olds, the recommended dosage is one 5ml dosage every 4-6 hours. For adults and children over 12 years of age, the recommended dosage is two 5ml spoonfuls every 4-6 hours.

Are there any side effects?

Like all medication, there are a number of potential different side effects when taking this syrup. The most common side effect is drowsiness. There are more potential side effects, such as:

  • Tiredness
  • A headache
  • Blurred vision
  • Indigestion
