Cetirizine + Pseudoephedrine

Uses of Cetirizine + Pseudoephedrine

Cetirizine + Pseudoephedrine is used to relieve symptoms of allergic rhinitis and the common cold, such as sneezing, a runny or blocked nose, and watery eyes. Cetirizine is an antihistamine, and Pseudoephedrine is a decongestant.

This combination is commonly used for:

• Allergic rhinitis: Relieves sneezing, itching, and a runny or blocked nose caused by allergens such as pollen or dust.
• Common cold symptoms: Eases nasal congestion and a runny nose associated with colds.
• Nasal congestion associated with sinusitis: Helps relieve pressure and congestion caused by blocked sinuses.
• Upper respiratory allergies: Relieves combined symptoms of nasal allergy and congestion.

Side effects of Cetirizine + Pseudoephedrine

  • Drowsiness

  • Dry mouth

  • Mild nausea

  • Headache

  • Fatigue

How Cetirizine + Pseudoephedrine works

Cetirizine + Pseudoephedrine works through two different actions that together relieve allergy and congestion symptoms.

Cetirizine is an antihistamine. It works by blocking histamine H1 receptors, preventing histamine from causing symptoms such as sneezing, itching, and a runny nose.

Pseudoephedrine is a decongestant. It works by narrowing the blood vessels in the nasal passages, which reduces swelling and congestion, making it easier to breathe.

Together, Cetirizine relieves allergy-type symptoms while Pseudoephedrine clears nasal congestion, providing more complete relief from allergy and cold symptoms.
