Hi You have not mentioned the age or weight of your child. Prednisolone is usually given in cases of severe wheeze if there is no response to bronchodilators alone. Given for a short duration and then tapered and stopped, it does not cause problems. But its better to use in severe wheeze. And better to avoid when child is having fever. What are the cough preparations you are giving him? Is he a known wheezer? You may give him Paracetamol in a dose of 15mg /kg/dose repeated every 6 hrs for his fever. For his cough, depending on the type of cough, depending on the presence or absence of chest signs, medications have to be chosen. You may speak to your doctor again. Hope my answer helps you. Wish a speedy recovery for your kid.
