Health experts are cautioning people who feel flu-like symptoms against immediately using flu medication. They say that without being diagnosed with flu, anyone using flu medication can potentially become more susceptible to the infectious disease. Tamiflu is one of the only two FDA approved flu medications in the country. And at Dr. Scott Friedberg's office in Boynton Beach, anyone with a cough or scratchy throat is coming in requesting a batch. "Phone calls went up yesterday... I had two people walk in... New patients who wanted to be seen, thinking they had the swine flu... And asking specifically for Tamiflu," said Dr. Friedberg. The increasing demand, Dr. Friedberg says, is due to increasing panic and hysteria associated with reports of more swine flu cases being discovered throughout America and the world.
