New guidelines for sinusitis target prescribing practices.

Experts suggest as many as half of all the prescriptions written for sinusitis each year are totally unnecessary. This is a big problem because not only are millions being wasted on drugs that will be ineffective, but the over-use of antibiotics is causing organisms to become resistant to some of the most common bugs. New guidelines offer the latest information on how to distinguish between viral and bacterial infections, as well as guidance on new therapeutic options when an antibiotic is warranted.
