Ambroxol + Guaifenesin + Levocetirizine + Phenylephrine is used to relieve productive cough and nasal congestion. It combines a mucolytic, an expectorant, an antihistamine, and a decongestant.
This combination is commonly used for:
• Productive cough: Thins and loosens mucus in the airways, making it easier to cough out.
• Nasal congestion: Relieves blocked or stuffy nose caused by the common cold, allergic rhinitis, or sinusitis.
• Allergic rhinitis: Reduces sneezing, itching, and a runny nose caused by allergens.
• Bronchitis: Eases chest congestion and thick airway secretions.
• Common cold and flu symptoms: Provides combined relief from cough, congestion, and allergy-related discomfort.

Nausea

Ambroxol + Guaifenesin + Levocetirizine + Phenylephrine works through four complementary actions to relieve cough, congestion, and allergy symptoms.
Ambroxol is a mucolytic that breaks down and thins thick mucus in the airways, making it easier to cough out.
Guaifenesin is an expectorant. It increases fluid secretions in the respiratory tract, which helps loosen mucus further and clear the airways.
Levocetirizine is an antihistamine. It blocks histamine, a chemical the body releases during an allergic reaction, reducing symptoms such as itching, sneezing, and a runny nose.
Phenylephrine is a decongestant that narrows blood vessels in the nasal passages, reducing swelling and congestion, and making breathing easier.
Together, these components relieve cough, clear congestion, and ease allergy symptoms associated with the common cold, bronchitis, allergic rhinitis, and sinusitis.
