Viral Infections And Antibiotics
Antibiotics treat bacterial infections, but influzena is caused by a virus, so antibiotics arent effective treatment for the flu. In fact, antibiotics may do more harm than good if you have the flu, says Dr. Tyler Policht, a family medicine doctor at Geisinger. They wont help you feel better, and they can cause other health problems.
Thats because viruses infect your body in a different way. Viruses infect your cells and multiply inside of them. For the virus, your cells act as a sort of Trojan horse so they can reproduce. Because they hide in your cells, antibiotics cant affect viruses in the same way.
Reasons Why You Did Not Receive Antibiotics From Your Provider
Have you ever left your health care providers office feeling frustrated that you didnt get an antibiotic for a sinus infection, sore throat, or ear infection? If you answered yes, you are not alone. Each year, millions of people visit their provider looking for antibiotics to cure infections. The reality is that most of these illness are caused by viruses and do not need antibiotics to get better. This includes the common cold, sore throats that are not caused by Strep, most coughs, bronchitis, ear infectionsand sinus infections. Yes, I said ear infections and sinus infections!
How can my doctor tell whether my illness is caused by a virus or bacteria? Though there is no easy way to tell for sure, infections caused by bacteria often take on certain characteristics. They tend to last longer, cause a fever of 100.4 degrees or greater, and may make people sick enough to be hospitalized. Evidence shows that infections lasting 10 days or longer are more likely caused by bacteria, and infections lasting less than that are caused by viruses.
At this point, you might be shaking your head in disbelief, or asking How can that be? You might even wonder why your doctor isnt treating you just in case. After all, 10 days is a long time to wait when you are feeling ill. The answer is tri-fold:

Can You Get The Covid
âAs per the CDC, there is no good evidence that acute illness makes a vaccine less effective or increases adverse effects,â says Dr. Robert Cole, MD, an intensive care medicine specialist in Camden, New Jersey, and author of How to Build a Smile. âHowever, as a precaution, the current recommendation is to delay vaccination if someone has any acute moderate or severe illness. In other words, if you have a mild cough, runny nose, or diarrhea, but are COVID negative, you can get the vaccine. Additionally, if you are taking antibiotics, you can also still get vaccinated safely.â
However, if you can wait to get vaccinated, you might want to do so. âIf you are sick, it would be best to wait to get the COVID vaccine until you are fully recuperated,â Dr. Soma Mandal, MD, a board-certified internist at Summit Medical Group in Berkeley Heights, New Jersey, tells Bustle. âThis is because the COVID-19 vaccine can potentially cause body aches, fever, fatigue, headache, joint and muscle pain, which can make the symptoms of an existing upper respiratory infection worse.â Why pile on more feeling sick if you can avoid it?

Conditions Are Often Treated With These Drugs But Shouldn’t Be
Every year doctors prescribe millions of antibiotics. But up to 43 percent of the antibiotics prescribed in doctors offices could be unnecessary, according to a nationally representative study published in the journal BMJ on Dec. 11.
Unless an infection is caused by bacteriawhich is usually not the casethe drugs will have no effect.
And antibiotics can cause serious side effects, says Lauri Hicks, D.O., a medical epidemiologist and head of the Centers for Disease Controls program Get Smart: Know When Antibiotics Work. These can include allergic reactions as well as an infection called C. difficile, which can cause severeand sometimes deadlydiarrhea.
Plus, she says, the more bacteria are exposed to antibiotics, the less likely they are to respond to the drugs. You increase your risk of developing an antibiotic-resistant infection the more antibiotics that you take, Hicks notes.
Doctors know that, but they often prescribe antibiotics anyway, in part because patients expect it.
Here are six conditions where its wise to question the use of antibiotics.
Avoid Mixing Alcohol And Antibiotics
If youre someone who likes to partake in alcoholic beverages, two weeks of an antibiotic like could put a wrench in your plans.
Its best to avoid alcohol while taking antibiotics. Heres why:
Alcohol weakens your immune system which slows down your bodys healing process.
Taking alcohol with Bactrim, Flagyl, or can result in severe nausea, vomiting, abdominal pain, and headaches.
Its probably best to err on the side of caution.

How To Take It
Try to space the doses evenly throughout the day. If you take it 3 times a day, this could be first thing in the morning, mid-afternoon and at bedtime.
You can take amoxicillin before or after food.
Swallow amoxicillin capsules whole with a drink of water. Do not chew or break them.
Amoxicillin is available as a liquid for children and people who find it difficult to swallow capsules.
If you or your child are taking liquid amoxicillin, it will usually be made up for you by your pharmacist. The medicine will come with a plastic syringe or spoon to help you measure out the right dose. If you do not have one, ask your pharmacist for one. Do not use a kitchen teaspoon as it will not measure the right amount.
How Do I Know If I Need To Take Antibiotics
It depends on what is causing your infection. These are some basic guidelines:
Colds and flu are caused by viruses. They cannot be cured with antibiotics.
Cough and bronchitis are almost always caused by viruses. But if these problems do not go away, germs may be the cause. Your doctor may want you to take an antibiotic.
A sore throat is usually caused by a virus and cannot be cured with an antibiotic. But strep throat is caused by germs. Your doctor will do a lab test before prescribing an antibiotic for strep throat.
Ear infections can be caused by viruses or germs. Antibiotics sometimes are used for ear infections, but they are not always needed. Antibiotics do not work for infections caused by viruses.
Sinus infections can be caused by viruses or germs. Antibiotics sometimes are used to treat sinus infections. But a runny nose with yellow or green mucus does not always mean you need to take an antibiotic.

What Is Antibiotic Overuse
Antibiotic overuse is when antibiotics are used when they’re not needed. Antibiotics are one of the great advances in medicine. But overprescribing them has led to resistant bacteria .
Some germs that were once very responsive to antibiotics have become more and more resistant. This can cause more serious infections, such as pneumococcal infections , skin infections, and tuberculosis.
Antibiotics Slow Down Your Response To Infection
In 2012, researchers at the University of Pennsylvania found that mice treated with antibiotics were unable to fully fight off the flu virus.6
This is because antibiotics wipe out the healthy bacteria that naturally protect the body.
You will find these protective microbes in the gut, on the surface of the skin, along the birth canal, and in the respiratory tract. Without these healthy communities of native microbes, the immune system isnt able to mount a strong attack on the flu virus. Researchers have also found that antibiotics slow down the clearance of an infection meaning more sick days out. When you treat a viral infection with antibiotics, you cripple your immune system.

What Happens When Antibiotics Are Overused
Taking antibiotics for colds and other viral illnesses doesn’t work and it can create bacteria that are harder to kill.
Taking antibiotics too often or for the wrong reasons can change bacteria so much that antibiotics don’t work against them. This is called bacterial resistance or antibiotic resistance. Some bacteria are now resistant to even the most powerful antibiotics available.
Antibiotic resistance is a growing problem. The Centers for Disease Control and Prevention calls it “one of the world’s most pressing public health problems.” It’s especially a concern in low-income and developing countries. That’s because:
- Health care providers there often lack quick, helpful diagnostic tools that can identify which illnesses are caused by bacteria and which are not.
- Many of the areas only recently got widespread access to antibiotics.
- Lack of clean water, poor sanitation, and limited vaccine programs contribute to the infections and illnesses that antibiotics are prescribed for.
Here’s Why Antibiotics May Give Viruses A Leg Up
27 March 18
Why are infections from the viruses that cause West Nile fever, dengue and even Zika deadly for some people but mild in others?
The answer thus far has been chalked up to being mostly a matter of human genetics. But a major factor in whether these viruses wreck your health may come down to the profile of bacteria that inhabit your intestines, called the gut microbiome, a new study in mice suggests.
The study, published today in the journal Cell Reports, found that these particular viral infections were more likely to be deadly if the infected mice had been treated in advance with antibiotics.
The reason is that antibiotics wipe out the gut microbiome, and this weakened microbiome somehow”impairs your immune system,” senior study author Dr. Michael Diamond, a professor of medicine, molecular microbiology, pathology and infectious disease at Washington University School of Medicine in St. Louis.
“The immune system is activated differently if the gut does not have a healthy microbiome,” Diamond said in a statement. “If someone is sick with a bacterial infection, they absolutely should take antibiotics. But it is important to remember that there may be collateral effects. You might be affecting your immune response to certain viral infections.”

Antibiotics Dont Work For Everything
Antibiotics fight infections caused by bacteria, but they wont work against infections caused by viruses. That means they are not effective against the flu, the common cold or COVID-19.
If that sounds like common sense, consider this: In a recent survey, one in three surveyed Americans wrongly believed that antibiotics work effectively against colds.
When you visit your doctor, be as specific as possible about all of your symptoms so he or she can narrow down the cause, Dr. Allan says. Figuring out whether its likely a bacterial or viral infection is step one.
For example, symptoms such as a consistently high fever , nasal discharge and severe facial pain may indicate a bacterial sinus infection. Most sinus infections are viral, but if these symptoms linger for many days without improvement, the cause may indeed be bacterial.
Likewise, that same high fever combined with ongoing ear pain may be signs of a bacterial ear infection. In both cases, antibiotics would be appropriate.
But not all infections are bacterial. A stuffy head and low-grade fever might be signs of a virus, for instance. Its critical to work with your doctor to get as clear a diagnosis as possible then proceed with the proper treatment.
That treatment is not always antibiotics. Sometimes easing your symptoms while letting your body fight off a virus is the proper course of action.
Can Amoxicillin Make You Feel Sick
Can amoxicillin make you feel sick? The most common side effects of amoxicillin are feeling sick and diarrhoea. Liquid amoxicillin can stain your teeth. This doesnt last and is removed by brushing. You can drink alcohol while taking amoxicillin.
Why do I feel sick after taking amoxicillin? The gut microbiome keeps the digestive system functioning and helps the immune system to defend against viral infection. When antibiotics upset the bacterial balance, a person may experience side effects, such as nausea or diarrhea.
Is it normal for antibiotics to make you feel sick? Side effects of antibiotics
Most antibiotics do not cause problems if theyre used properly and serious side effects are rare. The common side effects include: being sick. feeling sick.
Can antibiotics make you feel sick and tired? If youre taking prescription antibiotics, you may feel tired and fatigued. This may be a symptom of the infection being treated by the antibiotics, or it may be a serious, but rare, side effect of the antibiotic.

When Are Antibiotics Usually Prescribed
Antibiotics are normally only prescribed for more serious infections with germs .
Most common infections are caused by viruses, when an antibiotic will not be of use. Even if you have a mild bacterial infection, the immune system can clear most bacterial infections. For example, antibiotics usually do little to speed up recovery from most ear, nose and throat infections that are caused by bacteria.
So, do not be surprised if a doctor does not recommend an antibiotic for conditions caused by viruses or non-bacterial infections, or even for a mild bacterial infection.
However, you do need antibiotics if you have certain serious infections caused by bacteria, such as meningitis or pneumonia. In these situations, antibiotics are often life-saving. When you are ill, doctors are skilled at checking you over to rule out serious illness and to advise if an antibiotic is needed. Urine infections also commonly need antibiotics to prevent spread to the kidneys.
Antibiotics can also be prescribed to treat acne – a less serious condition. For acne, antibiotics can be taken by mouth or applied directly to the skin.
How Do You Avoid Antibiotic Side Effects
To avoid antibiotic side effects, only get a prescription for an antibiotic when it is needed. Taking antibiotics when they aren’t needed can put your child at risk for side effects and encourages antibiotic resistance. Antibiotic resistance means the medications are unable to work effectively because the germs have evolved to not be impacted by the drug.
You may be able to avoid or reduce your child’s chances of developing side effects by:
- Taking a probiotic, which helps replenish good bacteria in the gut, and may prevent diarrhea
- Protecting your child from the sun, by using sunscreen and avoiding peak sun hours, if the antibiotic increases the risk for sunburn
- Taking the antibiotic as prescribed
- Making sure your pediatrician knows about all other medications, including over-the-counter and natural remedies, that your child may be taking
- Storing the antibiotic properly
- Following directions on whether or not to take the antibiotic with food or on an empty stomach

Here’s When You Should Not Get The Covid Vaccine
If there’s a chance you have COVID, however, then it’s a different story. If you are having upper respiratory symptoms, the first thing you should do is get tested for COVID-19, Dr. Mandal says. For one thing, if you do have COVID or are awaiting test results, you should immediately self-isolate, and definitely shouldn’t expose the person giving you the shot. For another, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said in a Jan. 6 C-span interview that you should wait three months to get the COVID vaccine if you have already had the virus. The theory is that waiting would prevent interference between naturally occurring antibodies and the ones the vaccine triggers.
âIf you currently have the virus, then getting vaccinated will not be immediately helpful as the body takes time to mount an immune response,â says Dr. Eudene Harry, MD, a board-certified emergency medicine physician in Orlando, Florida. âIf you have recently received flu or any other vaccinations, then it is recommended by the CDC that you wait to receive COVID vaccine at least 14 days.â In any case, if you have had COVID-19, it is still recommended that you eventually receive the vaccine, as it is still unclear how long immunity from infection lasts, Dr. Harry says.
Can I Stop Taking Antibiotics If They Are Making Me Sick
If you have been fever-free for 24 to 48 hours and are feeling significantly better, its reasonable to call your doctor and ask if you can stop your antibiotic, she says. And be reassured that stopping short of a full course of antibiotics wont worsen the problem of antibiotic resistance, Peto says.

What Do Antibiotics Treat
Two major types of germs can make people sick: bacteria and viruses. They can cause diseases with similar symptoms, but they multiply and spread illness differently:
- Bacteria are living organisms existing as single cells. Bacteria are everywhere and most don’t cause any harm, and in some cases are beneficial. But some bacteria are harmful and cause illness by invading the body, multiplying, and interfering with normal body processes.Antibiotics work against bacteria because they kill these living organisms by stopping their growth and reproduction.
- Viruses, on the other hand, are not alive. Viruses grow and reproduce only after they’ve invaded other living cells. The body’s immune system can fight off some viruses before they cause illness, but others must simply run their course. Antibiotics do not work against viruses.
