Antibiotics: How they function, what they are used for, what side effects they have, and how to use them

Antibiotics are drugs that either kill or inhibit the growth of germs. They are recommended by doctors to treat bacterial infections. They accomplish this by eradicating germs and stopping their growth.



What antibiotics are, how they function, possible side effects, and antibiotic resistance are all covered in this article.

When taken appropriately, they are potent drugs that treat some diseases and can even save lives. They either kill germs or prevent them from multiplying.


The immune system can usually eliminate bacteria before they grow and produce symptoms. Even if symptoms appear, the immune system is typically able to handle and ward off the infection because white blood cells (WBCs) destroy harmful germs.


But, occasionally there are too many dangerous germs for the immune system to completely eliminate. The usage of antibiotics is appropriate here.


Penicillin was the original antibiotic. Ampicillin, amoxicillin, and penicillin G are just a few examples of penicillin-based that are still readily available and have been used for many years to treat a range of illnesses.


Modern antibiotics come in a variety of forms, but in the US, they are often only available with a prescription. Over-the-counter (OTC) creams and ointments contain topical antibiotics.


How do antibiotics function?

It comes in a variety of forms, each of which functions differently. However, the two primary things they do are:


The germs are eliminated with bactericidal antibiotics like penicillin. The bacterial cell wall or the contents of the cell are typically interfered with by these medications.


A strong antibacterial prevents bacterial growth.

After taking the initial dose, it could take a few hours or even days before someone feels better or their symptoms become better.


Why is it critical to take antibiotics when they are prescribed?

It should only be used when absolutely necessary, according to experts. This kills the bacteria and prevents it from multiplying and spreading to other parts of the body.

When bacteria stop responding to an antibiotic meant to kill them, antibiotic resistance occurs. Antibiotic resistance is becoming more common as a result of inappropriate antibiotic prescriptions.


Usually prescribing the incorrect drug or dosage might result in the overuse of antibiotics. When patients do not take antibiotics as directed by their doctor, misuse may also result. People can take preventative actions including finishing the prescribed course of therapy and refraining from sharing antibiotics with others, even if they share the same conditions.


A significant class of last-line antibiotics called carbapenems can cause some bacteria, including Enterobacterales, to develop resistance. An order of bacteria called enterobacterales is responsible for meningitis, pneumonia, and other illnesses. An example of an Enterobacterale is Escherichia coli (E. coli).


Drug resistance is beginning to spread, as predicted by the person who discovered the first antibiotic.


At this point, one of the biggest problems facing public health is antibiotic resistance.


What are antibiotics used to treat?

They are prescribed by a doctor to treat bacterial infections. Viral defense is ineffective.


Effective treatment of an infection depends on knowing whether it is bacterial or viral.


Most upper respiratory tract illnesses, including the common cold and flu, are brought on by viruses. These viruses are not susceptible to antibiotics.


Antibiotics may cause germs to grow resistant if they are misused or overused. As a result of the bacterium being able to strengthen its defenses, the antibiotic loses some of its effectiveness against that particular species of bacterium.


A broad-spectrum antibiotic can be prescribed by a doctor to treat a variety of ailments. A narrow-spectrum antibiotic works exclusively on a small number of bacteria.

While some antibiotics target anaerobic bacteria, others target aerobic bacteria. Anaerobic bacteria do not require oxygen while aerobic bacteria do.


In rare situations, such as before surgery, a medical provider may give antibiotics to prevent infection rather than to cure it. This is how antibiotics are used “prophylactically.” These are frequently taken before orthopedic and gastrointestinal operations.


Adverse consequences

The following negative effects of it are frequent:

  • vomiting
  • sickness
  • throw up
  • rash
  • stomach ache
  • Sun sensitivity while using tetracycline
  • Oral, gastrointestinal, and vaginal fungus infections with certain antibiotics or with extended usage

People who received antibiotics should not use any other medications or natural therapies without first consulting a doctor. Certain over-the-counter medications may also interact with it.


According to some doctors, antibiotics can diminish the effectiveness of oral contraceptives. However, research generally does not support this.


Those who have gastrointestinal problems or who do not take their oral contraception during illness owing to an upset stomach may find that its effectiveness is reduced.


In some cases, doctors may advise patients to take additional contraceptive precautions.


Doctors may also advise against drinking alcohol while taking some medications, such as doxycycline. However, moderate alcohol consumption is unlikely to interfere with the most regularly used antibiotics.


How to Apply

Antibiotics are normally taken orally. Doctors, on the other hand, can provide them through injection or directly to the infected area of the body.


Several antibiotics begin to work within a few hours. Doctors advise patients to finish the entire course of medicine to avoid reinfection.


If the drug is stopped before the course is completed, the germs may become resistant to future treatments. Those that recover will have had some interaction to the antibiotic and may confer immunity to it as a result.


What factors contribute to antibiotic resistance?

The majority of us have used antibiotics at some point in our lives. But what if the next time you take one of those little vulnerability pills, nothing happens? Your life may be at grave risk.


Bacteria are an important element of our environment, and we occupy our bodies with many of these microscopic organisms. They can, however, be the source of major health issues.


In our bodies, there are about as many human cells as bacterial cells, and our tiny guests pay their way by assisting our immune system and contributing to our metabolism.


Bacteria, on the other hand, occur in a variety of forms. Some can go from friend to foe, while others are simply unpleasant and will make us sick at any opportunity.
