About Cetirizine 10mg Hay Fever & Allergy Relief - 30 Tablets
  1. What are Cetirizine tablets?

    Cetirizine is a non-drowsy antihistamine medicine. You can buy Cetirizine on prescription, but it can also be purchased over the counter.

    This medicine provides swift and effective relief from the symptoms of common allergic conditions like hay fever and food allergies.

    Cetirizine tablets can be taken by adults and children over the age of 6. It is also available as Cetirizine Oral Solution, which can be used by children as young as 2 years old for hay fever and skin allergies.

    You can buy Cetirizine tablets without a prescription. 

    What is Cetirizine used to treat?

    Cetirizine 10mg tablets are used to treat the symptoms of a range of conditions, including:

    • Hay fever
    • Certain food allergies
    • Conjunctivitis
    • Eczema
    • Hives
    • Reactions to insect bites or stings

    Why is Cetirizine recommended for allergic conditions?

    These tablets contain the active ingredient cetirizine hydrochloride, which is an effective non-drowsy antihistamine used to relieve the symptoms associated with a number of common allergies including:

    Because it is a non-drowsy antihistamine, you are far less likely to suffer from drowsiness while taking Cetirizine tablets compared to other antihistamine medicines.

    It is suitable for adults and children aged 6 and above. 

    You should start to feel better within one hour of taking Cetirizine.

    How does Cetirizine work?

    Cetirizine belongs to a group of medicines known as antihistamines. It contains the active ingredient cetirizine hydrochloride, which works by blocking the effects of a chemical called histamine.

    Histamine is produced by your body when you come into contact with an allergy trigger, such as pollen, animal fur or dust. Histamine is useful for the body in most cases, but in an allergic reaction it causes unpleasant symptoms such as:

    • Stuffy, runny, itchy, or blocked nose
    • Itchy eyes
    • Watering eyes
    • Itchy red skin that can become cracked
    • Nausea and diarrhoea
    • Swollen eyes, face or tongue
    • Hives
    • Tight chest, wheezing

    By blocking the effects of histamine, your symptoms can be alleviated.

    Who can use Cetirizine tablets?

    Cetirizine 10mg tablets provide effective relief from the symptoms of allergies and hay fever, but they are not suitable for everyone to use.
