Cold With Green Snot? Sorry, No Antibiotics
Antibiotics No Help for Common Cold

July 19, 2005 -- It's official: Antibiotics do more harm than good for
people with common colds.
That's true even if you have what doctors call "purulent rhinitis"
-- what kids call "green snot."
Antibiotics are great for bacterial infections. Unfortunately, viruses cause
nearly all colds. Viruses don't mind if you take antibiotics, but your body
does. Diarrhea is the most common side effect.
Doctors used to give antibiotics to people with colds, hoping they would
prevent bacteria from infecting people when they were already ill. But that
doesn't really work, according to an exhaustive review of the medical
"Antibiotics appear to have no benefit in the treatment of acute upper
respiratory tract infections," write Bruce Arroll, MBChB, PhD, and Timothy
Kenealy, MBChB, of the University of Auckland in New Zealand.
"The implications for practice are that prescription of antibiotics
should not be given in the first instance as they will not improve the symptoms
and adult patients will get adverse effects."
What About Green Snot?
Arroll and Kenealy note that antibiotics can help some people with purulent
rhinitis/green snot. But the odds are against it. The chance antibiotics might
help is somewhere between 4 to 1 and 8 to 1.
Even if you think the intestinal side effects are worth that chance, another
factor makes it a bad bet. That fact: Overuse of antibiotics breeds
drug-resistant super germs. That means there may come a day when antibiotics
don't work -- not just for colds but for deadly illnesses.
So what does help?
"Patients will get a quicker fix if they take decongestants such as
Sudafed," Arroll says in a news release.
What about chest colds? Antibiotics don't help there, either --
even if you're coughing up ugly green phlegm.
