hello geethujoby... welcome to healthcare magic... wel after going through your query.. i can make out that the medications given by the pediatrician are specific and proper.. ciproflox is an antibiotic.. acetaminophen to reduce fever, cetrizine is an antiallergic which also relieves congestion and nasal block and nasal drainage, and levolin syrup contains levosalbutamol which is a brochodilator which dilates the brochus which wil augment in the proper ventilation.. there are some mild sideeffects of levolin which includes tremors.. tremors are one of the most common sideeffects.. tremors look like the babies hands and body are shivering.. but in fact its just a tremor... there is nothing to worry about it.. nothing wil happen with that and you can continue with medications.. well i hope this solves your query.. wish ur child a speedy recovery..
