Hooikoortstabletten Cetirizine Dihcl Etos (Cetirizine Dihydrochloride)

Hooikoortstabletten Cetirizine Dihcl Etos is used to relieve symptoms caused by allergic conditions. It may be taken by individuals experiencing seasonal or perennial allergy manifestations.

• Relief of sneezing, nasal congestion, and runny nose associated with allergic rhinitis.
• Reduction of itching, swelling, and hives in urticaria.
• Management of watery, itchy eyes due to allergic conjunctivitis.
• Supportive therapy for mild to moderate allergy symptoms when avoidance measures are insufficient.
• Suitable for adult and adolescent self‑care without prescription.

• Cetirizine dihydrochloride acts as a selective antagonist of peripheral histamine H1 receptors. By binding to these receptors, it blocks the action of endogenous histamine released during allergic reactions, thereby preventing the cascade of cellular events that lead to vasodilation, increased vascular permeability, and sensory nerve stimulation. This inhibition reduces the typical signs of allergy such as itching, swelling, and mucus production, without crossing the blood‑brain barrier in significant amounts.

Avoid

• Alcohol and other sedating agents (e.g., benzodiazepines, opioids) that may increase drowsiness.
• Monoamine oxidase inhibitors (MAOIs) taken within 14 days, due to potential additive antihistaminic effects.

Use with caution

• Other antihistamines or cold medicines containing antihistamine components.
• Anticholinergic drugs that may exacerbate dry mouth.
• CYP3A4 inhibitors (e.g., ketoconazole) that could raise cetirizine plasma levels.
• Medications that prolong QT interval; monitor cardiac status if combined.
