Cetrine Syrup 2.5 mg/5 ml Bottle 50 ml – Oral Antihistamine

Cetrine Syrup 2.5 mg/5 ml (Bottle 50 ml) is a liquid antihistamine medication formulated to help manage and relieve the symptoms of allergic reactions in both adults and children, under the guidance of a healthcare provider. Its active ingredient, cetirizine hydrochloride, belongs to a class of drugs known as second-generation antihistamines, which work by blocking histamine H₁ receptors in the body — the same receptors that trigger typical allergic symptoms when histamine is released in response to allergens.

Allergic reactions occur when the immune system mistakenly identifies harmless substances — such as pollen, dust mites, pet dander, insect bites or certain foods — as threats and releases histamine, a chemical that causes tissue inflammation and irritation. By inhibiting the action of histamine at its receptor sites, cetirizine helps reduce sneezing, runny or itchy nose, watery eyes, itching of the throat, skin rash, hives and other manifestations of allergy, providing comfort and improving daily functioning during allergy flare-ups.

The syrup formulation — concentrated at 2.5 mg of cetirizine per 5 ml of liquid — makes this product suitable for people who find swallowing tablets difficult, including children and older adults. The 50 ml bottle typically lasts for several weeks of dosing when used as directed.

How Cetrine Syrup Works

Cetirizine, the active component of this syrup, acts as a peripheral H₁ histamine receptor antagonist. Histamine is one of the principal chemicals released by the immune system that causes many symptoms of allergic inflammation, such as increased blood flow, swelling, itching and mucus secretion. By blocking histamine from binding to its receptors, cetirizine helps prevent or reduce the intensity of these symptoms when the body encounters allergenic triggers.

Because it is a second-generation antihistamine, cetirizine is less likely to cause sedation and central nervous system depression compared to older antihistamines — although mild drowsiness can still occur in some individuals.

Indications – When to Use

Cetrine Syrup is commonly used to manage allergic conditions such as:

• Seasonal allergic rhinitis (hay fever) — sneezing, runny or itchy nose, nasal congestion.

• Perennial allergic rhinitis — year-round allergy symptoms to non-seasonal triggers like dust, pets or mould.

• Chronic urticaria (hives) — itchy, raised skin lesions caused by allergic responses.

• Itchy, red, watery eyes associated with allergic conjunctivitis.

• Skin itching and rash after insect bites or mild allergens.

Effective allergy management with cetirizine can improve comfort and quality of life, especially during peak allergy seasons or when exposed to specific environmental triggers.

Directions for Use

The appropriate dose depends on age and medical guidance:

• Adults and older children (usually aged 12 years and above): A dose of 10 mg (equivalent to 10 ml syrup) once daily or as directed by a healthcare professional.

• Children (younger age groups): Lower doses are used depending on age and weight — for example, 5 ml or 2.5 ml doses at specified intervals for mid-childhood ages, but always follow a doctor’s direction or the exact dosing instructions on the product leaflet.

To ensure accurate dosing, use a calibrated dosing spoon or dropper provided with the product. The syrup may be taken with or without food.

Safety & Precautions

While generally well tolerated, cetirizine syrup must be used carefully, observing the following precautions:

• Do not exceed the recommended daily dose.

• Allergic sensitivity: Avoid use if you are allergic to cetirizine or related antihistamines such as hydroxyzine.

• Sedation risk: Although less sedating than older antihistamines, cetirizine can still cause drowsiness, fatigue or dizziness in some people; avoid driving or operating machinery if affected.

• Kidney or liver impairment: Inform your healthcare provider if you have significant kidney or liver disease, as dosage adjustments may be necessary.

• Pregnancy & breastfeeding: Use only if clearly needed and after consultation with a healthcare professional.

• Children: Always confirm appropriate dosing with a paediatrician for young children and never administer adult doses to children without guidance.

Possible Side Effects

Cetirizine syrup is generally well tolerated when taken as directed, but some individuals may experience:

• Mild drowsiness or tiredness

• Headache or dizziness

• Dry mouth

• Nausea or mild gastrointestinal discomfort

Severe allergic reactions to the syrup itself are rare, but if you experience difficulty breathing, swelling of face or throat, or severe rash, discontinue use and seek medical attention immediately.

Benefits of the Syrup Formulation

• Easy to swallow: Ideal for children, older adults and anyone who has difficulty swallowing tablets.

• Flexible dosing: Syrup allows precise adjustment of dose based on age and response.

• Rapid onset: Liquid form may provide symptom relief sooner than solid tablet form in some cases.

Storage & Handling

Store the syrup in its original bottle at room temperature (below 25 °C), away from direct sunlight and moisture. Keep the cap tightly closed and out of reach of children. Do not use after the expiry date printed on the packaging.
