Pulmoclear syrup is prescribed for my 5 years old son when he was suffering from late night coughing. It was cured wen we used the above syrup with a mild steroid called omnacortil. And now its a winter. Again my son is suffering from the same kind of allergy cough. Coughing in the late night wen he is in deep sleep. Now can I use the same prescription. Or should I consult a doctor again. please reply.
