dear user from your words i would like to tell you that your daughtet get viral infection that causes common cold and it was good behaviour to see the doctor to role out bacterial infection that may need antibiotics for treatment.....the treatment of this case is tylenol as antipyretic and may be cough sedative syrup helpful ...but you should know that viral infection causing common cold take course of few days and improvement occur gradually ...the treatment is only symptomatic...i feel your worry about fever so i want to say that fever can cause dehydration and we should manage it...tylenol has good effect against fever if the fever is mild but the most important step you should do is cold compresses.....cold compresses before any antipyretic treatment is very very important to manage fever ...cold compresses is the first step in lowering fever so you should do cold compresses for 10 minutes when the fever rise then give her tylenol...you can put her gradually under running water for relief of fever as the high grade fever doesnot reduced with out that even if you increased the dose of tylenol......so you can take this simple step and get out your worry and your daughter will be fine.......wish you and her ahealthy life
