Cetirizine targets histamine receptors in the body, specifically the H1 receptors, to reduce the common symptoms of allergies. By preventing histamine from binding to these receptors, Cetirizine reduces inflammation, itching, and other allergic responses, providing effective relief without the sedating effects seen with first-generation antihistamines.
Key Uses:
- Allergic Rhinitis: Relieves symptoms such as sneezing, runny nose, and itchy or watery eyes caused by seasonal or year-round allergies.
- Urticaria (Hives): Reduces itching and swelling associated with hives.
- Hay Fever: Alleviates common hay fever symptoms during pollen season.
Dosage and Administration:
- Adults and Children over 6 years: Typically 10 mg once a day, preferably in the evening.
- Children (2-5 years): 5 mg once a day.
- Take Cetirizine with or without food.
- It is important to follow your healthcare provider’s instructions regarding dosage.
Precautions:
- Liver and Kidney Conditions: People with liver or kidney problems may need an adjusted dosage.
- Pregnancy and Breastfeeding: Consult your doctor before use, especially if you are pregnant or breastfeeding.
- Alcohol and Sedation: Though Cetirizine is less sedating than older antihistamines, avoid alcohol to reduce the risk of drowsiness.
