Ralzine-AX Syrup is used to treat productive cough, bronchitis, asthma, emphysema, and other chronic inflammatory respiratory conditions. It contains Levocetirizine, an antihistamine that reduces allergic symptoms and airway inflammation, and Ambroxol, a mucolytic that thins and loosens mucus, making it easier to clear from the lungs. Together, they help relieve cough, ease breathing, and improve symptoms in conditions such as bronchitis, asthma, COPD, and emphysema (a long-term lung condition that causes shortness of breath). Common side effects of Ralzine-AX Syrup may include tiredness, drowsiness, nausea, vomiting, diarrhoea, indigestion, heartburn or bloating, abdominal pain, and dry mouth or throat. Most of these side effects are mild and temporary, but consult your doctor if they persist or worsen.
