Description

Benadryl Allergy Children’s 1mg/ml Oral Solution – 100ml

Benadryl Allergy Children’s 1mg/ml Oral Solution is a banana-flavoured liquid antihistamine suitable for children aged 2 years and over. It is used to relieve the symptoms of hay fever, allergic rhinitis, and other allergies such as pet dander, dust mites, and skin reactions like hives (urticaria).

How It Works

The active ingredient, cetirizine hydrochloride, is a non-sedating antihistamine. It works by blocking histamine receptors in the body — histamine is the chemical released during an allergic reaction that causes symptoms such as sneezing, itchy or watery eyes, and a runny nose. By blocking histamine, cetirizine helps to reduce and relieve these uncomfortable symptoms.

Like all medicines, cetirizine can cause side effects, although not everyone will experience them. Common side effects may include:

Who Should Not Take This Medicine

Do not give this medicine to your child if they:

• Are under 2 years of age
• Are allergic to cetirizine hydrochloride, hydroxyzine, or any other ingredient in this product
• Have severe kidney (renal) impairment
• Have a known hypersensitivity to piperazine derivatives

⸻

Interactions

Cetirizine is unlikely to interact with most medicines at the recommended dose; however, its sedative effect may be increased if taken alongside other medicines that cause drowsiness, such as sedatives or certain anxiety medications. Theophylline may slightly reduce the elimination of cetirizine from the body. Tell your PillSorted pharmacist or doctor about all medicines you are currently taking, including herbal remedies and supplements.

⸻

Pregnancy and Breastfeeding

This product is intended for children aged 2 years and over and is not indicated for use in adults or during pregnancy or breastfeeding. However, if a parent or carer is pregnant or breastfeeding and has incidentally handled this medicine, it is not expected to cause harm. Speak to your doctor or PillSorted pharmacist before use if you are pregnant, trying to conceive, or breastfeeding.

⸻

Alcohol

Although cetirizine is considered non-sedating, alcohol may enhance any drowsiness effect. This product is intended for use in children, so alcohol consumption is not relevant to the patient; however, parents and carers should ensure no alcohol is mixed with the solution when administering it to a child.

⸻

Driving and Operating Machinery

Cetirizine is classified as a non-sedating antihistamine; however, some children may still experience drowsiness. If your child appears drowsy after taking this medicine, ensure they do not ride a bicycle, use machinery, or engage in activities that require full alertness until the drowsiness has passed.

⸻

Store below 25°C in a dry place, away from direct sunlight and heat. Once opened, the solution should be used within 6 months — refer to the patient information leaflet for full details. Keep out of sight and reach of children. Do not use after the expiry date shown on the packaging.
