Hello Nandasiv, Asthalin contains salbutamol, a medicine which can increase the inner diameter of the child’s wind pipe. It also helps sputum (phlegm) to be coughed out. Cetrizine is a medicine which acts against histamine. (Histamine gets released during allergic reactions or inflammation) Ofloxacin is an antibiotic to control bacterial infection. These medicines are usually given to children with night symptoms of cough, and vomiting. Wheeze may or may not be present. Some general advice for such children: Avoid exposure to dust, fumes and pets. Keep a watch on food items (especially prawns, processed foods and preserved items) he eats. See whether cough/vomiting at night is more with any item of food. Such food must be avoided. Child should get adequate exercise. Hope your child recovers fast. Thanks for using healthcaremagic.com.
