Antibiotics are totally worthless and ineffective for the treatment of flu or other viral diseases. Viruses are not killed by antibiotics. While there are a few anti-viral drugs on the market, they are not commonly used. Treatment of the flu remains treatment of its symptoms. When your child wakes up with a sore throat, body aches and a fever of 105, it is a rare parent who will not be scared.
Most parents are especially concerned by the height of the fever.
High fevers are very common with influenza, and, fortunately, not dangerous in and of themselves. They may, however, be caused by other illnesses. If your child has a fever over 104 or looks sick, he should be seen by his Pediatriciain. A sore throat is also a reason to visit the doctor as strep throat can look very much like the flu and antibiotics are very effective against strep. If you child has the flu, try to get his fever down to less than 102, but it will likely go back up.
