How do antibiotics treat viral infections?
They don't. Antibiotics are targetted at bacteria. There are also antifungals and a very few, quite new, not 100% effective anti-virals.
Why do doctors prescibe antibiotics for viral infections when antibiotics are supposed to be for bacterial infections?
Antibiotics can not treat Viral infections because they kill bacteria, not virus'. There are anti virals, like tamiflu, and valtrex that treat virus' but those are usually only given to people to prevent a virus, not usually treat it. Virus' and bacteria are very different. And even with antibiotics, there are certain antibiotics for certain infections. Not all antibiotics kill all bacteria. Like augmentin kills E.coli (like in a UTI), where as Doxycycline kills Chlamydia…
You would not be given any antibiotic for use to treat a cold or flu. They are both viral infections, not bacterial infections. Antibiotics are only for bacterial infections. If you have a secondary bacterial infection with a viral infection, you might be prescribed an antibiotic to treat that secondary infection, but not for the virus itself.
Yes. Viral infections should always be treated without antibiotics. There are some viral infections that should be treated with anti-viral medications, HIV, for example, and some that can be treated with antivirals. Antibiotics do not help with viral infections and can encourage the growth of more antibiotic resistant bacteria.
Antibiotics are ineffective in this case because they fight bacteria, not viruses. Taking antibiotics for a viral infection can lead to an antibiotic resistant infection that is harder to treat, as well as other harmful side effects. The rate of drug resistant infections is on the rise in hospitals, so please resist the urge!
In cats, the majority of upper respiratory infections are viral infections, so antibiotics are not effective to clear up the infection. However, sometimes cats get secondary bacterial infections. For these infections, if antibiotics are going to be used, the typical medication is amoxicillin or another penicillin-class drug.
That is true but viral infections stay dormant in the body until the nucleic acids can enter a cell then spreading itself throughout the body. Viral infections can not be cured unlike bacterial infections. Bacterial infections enter the body by air... thus entering the bloodstream going to any part of the body. The bacteria may even have a specific place in the blood it may want to go. Antibiotics were made to cure bacterial infections…
Antibiotics cannot treat a viral infection. An infection caused by a virus. A viral infection includes the common cold, the flu, viral meningitis and most sore throats. Doctors will prescribe an antibiotic for some people with the flu though to keep them from getting a secondary infection like pneumonia, like bacterial pneumonia. The over prescribing of antibiotics and the use of so much antibiotics in our food supply has hurt our health and caused antibiotics…
None whatsoever. No antibiotic has any effect whatsoever on a viral infection, and prescribing antibiotics for viral infections is considered unethical by the medical profession. There are a few rudimentary anti-viral drugs now on the market that can help viral infections if administered early in the infection, and more will probably follow as time goes on.
