Thanks for posting on HealthCareMagic. The fever is caused due to an infection and the blood counts indicate that the infection is of bacterial origin. The reduction of WBC count indicates that the child is responding to the antibiotics and the dose needs to be continued further. Please note that the dose of azithromycin is once daily and not thrice daily. Meftal P contains paracetamol and is meant to control the fever. The temperature needs to be controlled either with medicines or cold sponging or both. Else, high temperature can cause damage to the brain. So the medicines for control of fever need to be continued as required. Nebulisation helps in dilating the airway tracts and diluting the cough. So it provides relief and needs to be continued too. Overall the treatment is on the right lines and you need not worry. Hope that helps. Feel free to revert back in case of further queries if any.
