Allecet Syrup Uses

Allecet Syrup is a widely used allergy medicine in South Africa that helps relieve common symptoms such as sneezing, itchy skin, watery eyes, and a runny nose. It belongs to a group of medicines called antihistamines and is suitable for both adults and children (as guided by age recommendations).


What it is and what it is used for

Active ingredient and class

Allecet Syrup contains cetirizine dihydrochloride, which is classified as a second-generation antihistamine.

  • Strength: 1 mg per 1 mL
  • Class: Antihistamine (H1 receptor blocker)

Indications (uses)

Allecet Syrup is used to treat allergic conditions, including:

  • Hay fever (allergic rhinitis)
    Helps reduce sneezing, nasal congestion, and watery eyes.
  • Skin allergies (including chronic urticaria or hives)
    Reduces itching, redness, and swelling.
  • Allergic conjunctivitis
    Helps relieve eye irritation and watering.
  • Other allergy-related reactions (under medical supervision), such as:
  • Insect bites
  • Food-related allergic responses

How it works

When your body reacts to an allergen (like pollen or dust), it releases a chemical called histamine. This causes symptoms such as itching, swelling, and a runny nose.

Cetirizine works by:

  • Blocking H1 histamine receptors
  • Preventing histamine from triggering allergic symptoms

In simple terms, it stops the allergy reaction before it causes discomfort.


Who should NOT use this medicine

Do not use Allecet Syrup if:

  • You are allergic to cetirizine or hydroxyzine
  • You have severe kidney problems without proper dose adjustment

Important: Always consult a healthcare professional if you are unsure.
