About Allercet Syrup

Allercet Syrup is a syrup used to relieve allergy symptoms in children. It helps manage symptoms such as sneezing, a runny or itchy nose, watery eyes, and itchy skin rashes or hives. Doctors commonly prescribe this medicine to help children feel more comfortable during allergy seasons or after exposure to environmental allergy triggers.

This medicine is typically taken once daily, and it is important to give it to your child at the same time each day to maintain consistent relief. It can be taken with or without food, making it easy to fit into your child's daily routine. Simple changes, such as keeping windows closed during high pollen seasons and washing hands after playing outdoors, can further support your child's allergy management.

While this medicine is generally well-tolerated, some children may experience mild side effects like drowsiness, a dry mouth, or a mild headache. These symptoms usually go away on their own, but you should contact your doctor immediately if you notice any unusual behaviour, severe skin rashes, or breathing difficulties.

Before starting Allercet Syrup, inform your doctor if your child has kidney problems, epilepsy, or a history of seizures. This medicine should not be given to infants under the age recommended on the product packaging or by your paediatrician. Always consult your healthcare provider to ensure it is safe for your child's specific age group and health status.

This medicine can interact with other drugs that cause drowsiness, such as cold medicines or other allergy treatments, which may make your child overly sleepy. Since this is a paediatric formulation, avoid giving it alongside any other antihistamines unless directed by a doctor. If you are caring for a teenager, remind them to avoid alcohol while taking this medicine, as it can significantly increase drowsiness.

Allercet Syrup helps relieve the symptoms of allergic conditions caused by the release of histamine. Your doctor may prescribe it for the following conditions:

  • Allergic Rhinitis (Hay Fever): Allercet Syrup helps relieve seasonal and year-round nose allergies by reducing sneezing, runny nose, and nasal itching.
  • Allergic Conjunctivitis: It helps soothe red, itchy, and watery eyes caused by airborne allergens like pollen, pet dander, or dust mites.
  • Hives (Urticaria): It relieves the intense itching, redness, and swelling associated with hives in children.

How Allercet Syrup Works

Allercet Syrup contains cetirizine, a second-generation antihistamine. It works by blocking the action of histamine, a natural chemical released by the body during an allergic reaction. Histamine is responsible for symptoms such as sneezing, a runny nose, itchy eyes, and skin itching. By preventing histamine from attaching to its receptors, Allercet Syrup helps relieve allergy symptoms and provides long-lasting relief. As a newer-generation antihistamine, it is less likely to cause drowsiness than older antihistamines, although some children may still feel sleepy.
