Viruses insert their genetic material into a human cell’s DNA in order to reproduce. Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus.
Antibiotics do not work for viral infections. There are antiviral medicines to treat some viral infections. Vaccines can help prevent you from getting many viral diseases.
If you take an antibiotic when you actually have a viral infection, the antibiotic attacks bacteria in your body — bacteria that are either beneficial or at least not causing disease.
But the treatment of viral infections has proved more challenging, primarily because viruses are relatively tiny and reproduce inside cells. For some viral diseases, such as herpes simplex virus infections, HIV/AIDS, and influenza, antiviral medications have become available.
Good hygiene: the primary way to prevent infections
- Wash your hands well.
- Cover a cough.
- Wash and bandage all cuts.
- Do not pick at healing wounds or blemishes, or squeeze pimples.
- Don’t share dishes, glasses, or eating utensils.
- Avoid direct contact with napkins, tissues, handkerchiefs, or similar items used by others.
- Abacavir for HIV (Ziagen)
- Aciclovir cream (Cymex Ultra, Zovirax)
- Aciclovir eye ointment.
- Aciclovir for viral infections (Zovirax)
- Adefovir for hepatitis B (Hepsera)
- Amorolfine for fungal nail infections (Loceryl, Curanail, Omicur)
- Amoxicillin for infections.
- Ampicillin for infections (Penbritin)
The drugs used for viral infection are Acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex) are effective against herpesvirus, including herpes zoster and herpes genitalis. Drugs used for treatment for viral fever are Acetaminophen(Tylenolothers)ibuprofen (Advil,motrin IB others).
Antibiotics are useless against viral infections. This is because viruses are so simple that they use their host cells to perform their activities for them. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.
Why don’t antibiotics work for viral infections? Antibiotics are not effective for treating viral infections. Viruses are completely different than bacteria. Antibiotics target specific structures on bacteria that viruses don’t have or are different in viruses. The beauty of antibiotics is that they are mostly specific to bacteria …
When is it not necessary to take antibiotics?
An antibiotic medicine is not needed if a virus is causing an infection. This is because: Antibiotics do not kill viruses. Antibiotics only kill germs called bacteria. Overuse of antibiotics when they have not been necessary has led to some bacteria becoming resistant to them.
Is it safe to take antibiotics if you have a fever?
They are not useful in treating viral infection and fever. It can, rather, be harmful to your body if taken unreasonably. Antibiotic medicines are not meant for viral infections or flu. It is extremely dangerous to use antibiotics when you are suffering from viral fever.
In complicated or prolonged viral infections, bacteria may invade as well, and cause what is known as a “ secondary bacterial infection ”. In these cases, your doctor may prescribe an antibiotic, if one is needed, to kill the specific invading bacteria.
What types of infections can not be treated with antibiotics?
- Colds and flus
- Chicken pox (varicella)
- Measles (rubeola)
- German measles (rubella)
- Roseola infantum (human herpes virus HHV-6 and HHV-7)
- Erythema infectiosum)
- diarrhea (gastroenteritis)
Antibiotics are ineffective against viruses because viruses are not composed of cells. Antibiotics break down a bacteria’s cell walls or stopping the bacteria’s ability to repair its DNA. This is why it was advised not to take antibiotics for viral infections. It may lead to antibiotic resistance in the future.
Why do antibiotics fail to kill viruses?
Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria. Antibiotics work by targeting the growth machinery in bacteria (not viruses) to kill or inhibit those particular bacteria.
When not to take antibiotics?
When NOT To Use Antibiotics. Antibiotics are not the correct choice for all infections. For example, most sore throats, cough and colds, flu or acute sinusitis are viral in origin (not bacterial) and do not need an antibiotic.
