Do you know how to use antibiotics correctly? Firstly, it is important to make a distinction between antimicrobial and antibiotic. Antimicrobial is any compounds that would be used to treat or prevent numerous infections, and could be included anti-bacterial, anti-viral, anti-fungal and anti-protozoal (HMA Definitions, 2012). Antibiotic, or anti-bacterial, is a drug made by substances obtained by different microorganisms and fungi, and it is used to treat bacterial infections, avoiding the growth or killing the bacteria. The first antibiotic was penicillin, and it was discovered by Alexander Fleming in 1928 (Davies, 2010). Alexander Fleming took vacations and forgot his petri dishes at his table without protection (Rosenberg). When he returned, …show more content…
As mentioned before, the super bacteria are developed and become stronger due to noncompliance with medical recommendations. This form of infection can be fatal since there are several types of antibiotics. If a person has an antibiotic-resistant bacteria, doctors will recommend another antibiotic, yet the new one will be more toxic and potent that the common-used drug. An example would be about the gonorrhea, a sexually transmitted disease. The therapy was just penicillin, but nowadays, penicillin does not work; it is necessary the use of either fluoroquinolones or cephalosporins (Antibiotic resistance, 2011), which are potent antibiotics when it is compared with penicillin. The new antibiotics drugs development is being stimulated by the government agencies. The Food and Drug Administration (FDA) announced only one new antibiotic in the period from 2008-2012 (Dantas & Morten, 2014). Therefore, doctors must guide their patients about how use correctly the antibiotics to avoid stronger medicine that can have more side …show more content…
First, antibiotics can lose their effects, because the population is exposed it in different ways; for example, plants and animals that are treated with antibiotics that are similar to those used for human. Some antibiotics that are used in the wrong moments generate the biggest problem: bacterium resistance. The bacterium will survive, and the treatment will not be effective, causing the antibiotic useless for some treatments. Second, many drugs will have side effects, and when a person constantly uses, it not only will cause acute effects, but also will cause chronic effects that can be fatal. Chronic effects are severe, because they can affect the liver and kidney that are responsible for cleansing the human organism, excreting useless or toxic metabolites. Third, there are interactions of antibiotics with other substances that affect the treatment, causing either more or fewer effects. The commonest examples are oral contraceptive, which loses its effects, and alcohol, which increase side effects. However, there is still no evidence that proves these results. Nevertheless, doctors do not recommend drinking alcohol and antibiotic together, and use alternative contraceptive methods when the woman is on antibiotic therapy. For these reasons, the misuse of antibiotics is dangerous; may decrease the treatment efficiency, have side effects and interact with other

It is undeniable that the recent discovery of antibiotics and disinfectants in the past century is leading to the creation of increasingly dangerous antibiotic-resistant bacteria. Super bugs like Methicillin-resistant Staphylococcus have begun breaking out in hospital areas, killing more and more patients due to the lack of people following through with simple safety measures. In order to stop the creation and spread of antibiotic-resistant super bugs, proper precautions must be taken such as avoiding antibacterial cleaners, following through with instructions when taking prescriptions and maintaining adequate hand hygiene. Through adhering to basic safety rules, the creation and spread of super bugs can be minimized and all together discontinued from occurring at such a rapid rate.
According to USA Today, U.S. doctors are prescribing enough antibiotics to give to 4 out of 5 Americans every year, an alarming pace that suggests they are being excruciatingly overused. In fact, Dr. Aunna Pourang from MD states, “to give you an idea of how high the pressure is to prescribe antibiotics, I didn’t get a job once because during the interview I told the lead physician that I only prescribe antibiotic prescriptions when they are warranted.” The development and widespread obsession of antibiotics, or drugs that kill bacteria and thereby reduce infection, has helped billions of people live longer, healthier lives. Unfortunately, the more we rely on and abuse antibiotics, the more bacteria develop resistance to them, which makes treating infections that much more challenging and leads to the growth of drug-resistant strains of bacteria. Research from the Center of Disease Control found that two million people in the United States become infected with antibiotic resistant bacteria, while 23,000 people die from such infections each year. Americans often aren’t informed on the power of the human body and rush to assumptions when perfection isn’t present. In a nutshell, the obsession of antibiotics is quite deadly and needs to be addressed before it’s too
The natural components of antibiotics have been used as local remedies long before humans understood the reasons why these sometimes-radical treatments worked. Penicillin became the first manufactured antibiotic after physician Alexander Fleming published articles regarding this bacteria-disabling mold in 1928. Come 1932, penicillin was commonly used to treat infected war injuries, saving the lives of unnumbered soldiers (Lewis). Since then, penicillin has b...
Long before humans discovered antibiotics, they existed in nature. So naturally, after penicillin was introduced, some germs were already naturally resistant to the drug. As we used more and more of the antibiotics, we incidentally caused drug-resistant germs to progress. So, even if you’ve never misused antibiotics, you could still become infected by bacterium most drugs won’t kill. For each drug, there are germs genetically programmed to survive- some w/ outer walls tough for antibiotic to cross, others with ways to dump the drugs back out before they can work, and yet others can inactivate the antibiotic. Even worse, by passing tiny packets of genetic material to other bacteria, these survivor germs sometimes also pass the formula for resistance to the other bacteria. The best way you can protect yourself and your family against drug-resistant bacteria is by using antibiotics correctly. Taking them when they’re not needed encourages the takeover of drug-resistant strains in your body. (Redbook, pg.95) That’s because when antibiotics are given, the normal bacteria in your body are killed off, leaving lots of bacterial “parking spaces'; open. And the germ left to fill them is the drug-resistant ones. (Redbook, pg.95) So far, antibiotic resistance has not been a big problem with streptococcus A, the germ familiar to all of us for causing millions of cases of strep thr...
“The World Health Organization projects that as drug effectiveness decreases and antibiotic resistance increases, public education becomes more and more crucial” (476) Antibiotics were discovered in 1940 and since have been abused and misused. Between bad practices and lack of proper education antibiotic resistance has been allowed to occur. The only way to combat bacterial infections is with strong patient education and following the correct schedule in taking antibiotics.
, prevention and control in our hospitals, have left South Africa, like the rest of the international community, on the brink of a return to an era of stubbornly resistant pathogenic bacteria towards antibiotics.
Bacteria that is resistant to antibiotics is a major problem not only for the United States, but worldwide. According to the Centers for Disease Control and Prevention (2012) the cause is related to “widespread overuse, as well as inappropriate use, of antibiotics that is fueling antibiotic resistance”. According to World Health Organization (2013) resistance is a global concern for several reasons; it impedes the control of infectious diseases, increases healthcare costs, and the death rate for patients with resistant bacterial infections is twice of those with non-resistant bacterial infections.
Resistance arises from mutations that are not under the control of humans, but the evolution of bacteria has been sped along by the overexposure of antibiotics to both people and animals. The number of antibiotic-resistant strains of bacteria in an area is closely related to the frequency that antibiotics that are prescribed (Todar, 2012). Patients often unnecessarily demand antibiotics to treat common colds or simple illnesses that are not caused by bacteria. Instead, these infections are caused by viruses which, unlike bacteria, are unaffected by antibiotics. Incorrect diagnosis can also lead patients to using unnecessary antibiotics, which can sometimes be even more dangerous than otherwise left untreated. Besides the fact that antibiotics kill off beneficial bacteria in the intestines, misuse of antibiotics provides an opportunity ...
In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.
This turn of events presents us with an alarming problem. Strains of bacteria that are resistant to all prescribed antibiotics are beginning to appear. As a result, diseases such as tuberculosis and penicillin-resistant gonorrhea are reemerging on a worldwide scale (1). Resistance first appears in a population of bacteria through conditions that favor its selection. When an antibiotic attacks a group of bacteria, cells that are highly susceptible to the medicine will die.
Every year, antibiotic-resistant bacteria are threatening more and more people. As much of a problem as it is, many people are not educated on the term drug resistance. Since it is such a growing concern, it becomes confusing as to why drug resistance is occurring and what can be done to prevent it. Because drug resistance is such a health problem, determining what it is, how these bacteria can acquire the antimicrobial agents, and the possible solutions to the resistance are the types of actions that need to be taken in order to have a better understanding of how truly powerful these drug resistant bacteria are.
Thesis: With the advent of antibiotics in 1929 Fleming said, "The time may come when penicillin can be bought by anyone in the shops.Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant."With the overuse of antibiotics today we have seen this very idea come to be.Over usage is caused most prevalently by a lack of education on the part of the patient.Thus stated, the way to overcome such a circumstance is to educate, not only the patient but also the physician.
The discovery of antibiotics is attributed to Alexander Fleming who discovered the first antibiotic to be commercially used (Penicillin) in approximately 1928. An antibiotic, also known as an antimicrobial, is a medication that is taken in order to either destroy or slow the growth rate of bacteria. Antibiotics are integral to the success of many medical practises, such as; surgical procedures, organ transplants, the treatment of cancer and the treatment of the critically ill. (Ramanan Laxminarayan, 2013)
The most effective way to combat pathogenic bacteria which invade the body is the use of antibiotics. Overexposure to antibiotics can easily lead to resistant strains of bacteria. Resistance is dangerous because bacteria can easily spread from person to person. Simple methods for preventing excessive bacterial spread are often overlooked. Not all preventative measures are even adequate. Doctors and patients often use antibiotics unnecessarily or incorrectly, leading to greater resistance. Antibiotics are used heavily in livestock and this excessive antibiotic use can create resistant bacteria and transfer them to humans. In order to reduce resistant bacteria,
