Antibiotics
Antibiotics (drugs used to treat bacterial infections) are overwhelmingly misprescribed in the United States. Despite congressional hearings and numerous academic studies on this issue, it has become the general consensus that 40 to 60% of all antibiotics in this country are misprescribed. New studies continue to confirm the fact that a large proportion of antibiotic prescribing for both children and adults continues to be inappropriate.
Fluoroquinolones
One of the biggest-selling and most overprescribed classes of drugs in the United States is the family called fluoroquinolones. One clue that a drug your doctor wants to give you is in this class is the fact that the generic names of all such drugs approved in the United States include the sequence floxacin. These drugs have been alternatives for individuals allergic to, or with infections resistant to, other antibiotics. Some fluoroquinolones are commonly misprescribed for colds, sore throats, bladder infections, or community-acquired (as opposed to hospital-acquired) pneumonia.
