MONDAY, Nov. 1 (HealthDay News) -- The injected antibiotic Teflaro (ceftaroline fosamil) has been approved by the U.S. Food and Drug Administration to treat bacterial infections including community acquired bacterial pneumonia and methicillin-resistant Staphylococcus aureus (MRSA), the agency said in a news release.

MRSA, resistant to a host of common antibiotics, is typically acquired in hospitals and other health care settings.

Teflaro is among a class of antibiotics called cephalosporins, which treat infections by interfering with the bacterial cell wall.

In clinical testing, the most common side effects of Teflaro included diarrhea, nausea and rash. The drug shouldn't be used by people with a known history of allergy or sensitivity to cephalosporins, the FDA said.
