Zirtek Allergy Relief Solution for Children 70ml

Is Cetirizine Syrup for Children Right for Your Child's Allergies?

If your child sneezes constantly through spring, wakes up with itchy eyes, or breaks out in hives after stroking a pet, you'll know how disruptive allergies can be — for them and for you. Cetirizine syrup for children is one of the most widely recommended over-the-counter options for managing these symptoms, and Zirtek Allergy Relief Solution for Children 70ml delivers exactly that. It contains cetirizine hydrochloride 5mg/5ml in a sugar-free, banana-flavoured liquid that's easy to measure and simple to give. At just £4.54, it's an accessible choice for families dealing with seasonal or year-round allergic conditions. You can find it alongside other trusted options in our allergy and hay fever collection.

Cetirizine is a second-generation antihistamine, which means it's less likely to cause the heavy sedation associated with older antihistamines like chlorphenamine. It's been used in children across the UK for many years and has a well-established safety profile when used as directed.

How Does Zirtek Allergy Relief Solution Work in Children?

When your child encounters an allergen — pollen, pet dander, dust mites, or certain foods — their immune system releases a chemical called histamine. Histamine binds to H1 receptors throughout the body, triggering the familiar cascade of sneezing, itching, watery eyes, and skin reactions. Cetirizine works by selectively blocking those H1 receptors, preventing histamine from binding and reducing the allergic response.

• Cetirizine is absorbed quickly after oral administration, typically reaching peak plasma concentration within one hour.
• It has a long duration of action, meaning a single dose can provide relief for up to 24 hours.
• Because it crosses the blood-brain barrier only minimally, it causes less drowsiness than first-generation antihistamines.
• It is primarily excreted via the kidneys, so dose adjustments may be needed in children with renal impairment.

Which Children Is Zirtek Allergy Solution Suitable For?

Zirtek Allergy Relief Solution is indicated for children aged 2 years and over. It's particularly useful for children who struggle to swallow tablets, making the liquid formulation a practical alternative. It is used to relieve symptoms associated with:

• Seasonal allergic rhinitis (hay fever) — sneezing, runny or blocked nose, itchy eyes
• Perennial allergic rhinitis — year-round symptoms triggered by dust mites or pet allergens
• Urticaria (hives) — itchy, raised welts on the skin caused by an allergic reaction
• Allergic conjunctivitis — red, itchy, watery eyes linked to allergen exposure

It is not suitable for children under 2 years of age. Children with known hypersensitivity to cetirizine, hydroxyzine, or any of the excipients should not use this product.

How Should Zirtek Children's Solution Be Stored and Is It Clinically Suitable?

This cetirizine syrup for children should be stored below 25°C, away from direct sunlight, and kept out of the reach and sight of children. Once opened, check the expiry date on the bottle and do not use beyond it. The solution does not require refrigeration, which makes it convenient for families on the go — whether at home or travelling during hay fever season. If your child has kidney or liver problems, speak to your GP or pharmacist before use, as dose adjustments may be necessary.

For children who also experience eye-related allergy symptoms, it may be worth exploring our eye care range for complementary relief options.

What Is Zirtek Allergy Relief Solution and What Is It Used For?

Zirtek Allergy Relief Solution for Children is an oral antihistamine liquid containing cetirizine hydrochloride 5mg per 5ml. It is used to relieve the symptoms of allergic conditions in children aged 2 years and over. These include hay fever (seasonal allergic rhinitis), year-round allergic rhinitis caused by indoor allergens, urticaria (hives), and allergic conjunctivitis. The solution is sugar-free and banana-flavoured, making it more palatable for young children who may resist taking medicine.

Cetirizine is classified as a second-generation antihistamine. Unlike older antihistamines, it is far less likely to cause significant sedation, which means most children can take it during the day without it affecting their concentration at school or their normal activities.

What Do You Need to Know Before Giving Your Child Zirtek Solution?

Before giving this medicine to your child, read the following carefully. Some children should not use this product, and others may need extra monitoring.

Do not use Zirtek Allergy Solution if your child:

• Is under 2 years of age
• Has a known allergy to cetirizine hydrochloride, hydroxyzine, piperazine derivatives, or any other ingredient in the solution
• Has severe kidney disease (end-stage renal impairment)

Speak to your pharmacist or GP before use if your child:

• Has kidney or liver problems — dose adjustment may be required
• Has epilepsy or a history of seizures
• Is due to have allergy skin-prick testing — cetirizine should be stopped at least three days before testing
• Has difficulty passing urine (urinary retention)

Drug interactions to be aware of:

• Alcohol — may increase the risk of drowsiness (relevant for older children and adolescents)
• Other CNS depressants — sedative effects may be enhanced
• Theophylline — may slightly reduce the clearance of cetirizine

How Should You Give Your Child Zirtek Allergy Solution?

Always follow the dosage instructions on the label or as directed by your pharmacist. Use the measuring device provided with the bottle — never use a household teaspoon, as this can lead to inaccurate dosing.

1. Shake the bottle gently before use.
2. Use the oral syringe or measuring spoon provided to draw up the correct dose.
3. Administer the solution directly into your child's mouth or mix with a small amount of water if preferred.
4. Replace the cap securely after use.
5. Record the time of each dose to avoid accidental double-dosing.

If your child also experiences nasal congestion or throat irritation alongside their allergy symptoms, our ear, nose and throat range may offer additional support.

Stop giving the medicine and seek urgent medical attention if your child develops signs of a serious allergic reaction, such as swelling of the face, lips, or throat, difficulty breathing, or a severe skin rash. These reactions are rare but require immediate attention.
