Antibiotics are medicines that are used to treat several diseases or infections caused by bacteria. Antibiotics that affect a large range of bacteria are referred to as broad-spectrum antibiotics. If the antibiotics affect only a few types of bacteria it is called as narrow spectrum antibiotics.
The first antibiotic was penicillin. Penicillin related antibiotics such as amoxicillin, ampicillin and benzylpenicillin are widely used to treat various infections. At present different types of modern antibiotics have come up and purchases of antibiotics online can be done very easily.
What do antibiotics do?
Antibiotics block the vital processes in bacteria, and after that either kill the bacteria or stop them from multiplying. Because of this the body's natural immune system can fight any bacterial infection. The type of antibiotic used will depend on the type of bacteria they work against. Different types of antibiotics work in different ways. For example, taking penicillin will result in destroying bacterial cell walls, while other antibiotics can affect the way the bacterial cell works. Hence while choosing an antibiotic the doctor first identify the bacteria that is causing the particular infection. Some time even a test is done so as to identify the exact type of bacteria that is causing the infection.

Side effects of antibiotics
Like all the medicines antibiotics if taken come with its share of side effects. Some of the common antibiotics side effects include:
- Diarrhoea, nausea and vomiting: The most common antibiotics side effects are problems related to stomach such as vomiting, nausea and diarrhoea. This happens because taking antibiotics can cause the gut lining to become inflamed and can also disturb the good or the bad bacteria in the gut.
- Thrush: This infection is caused by the yeast Candida albicans which lives in the body and vagina but is harmless. Under normal circumstances it is kept in control by the immunity system and other bacteria ain the body. However, taking antibiotics can result in upsetting the normal balance of bacteria in the body and also vagina and allow candida to grow causing thrush.
- Clostridium difficile-associated disease: Together with many bacteria, Clostridium difficile is also a bacterium that is found in the gut of many people. All such bacteria live in balance together. However, if you are taking antibiotic to treat any of the infection you are suffering from, the antibiotic may kill such bacteria causing the infection and also some of the good bacteria that are there in your gut, but it does not kill C. difficile. Because of this it allows C. difficile bacteria to thrive and multiply and then it may lead to C. difficile-associated disease.
- Allergic reactions: Taking some antibiotics may result in hypersensitive or allergic reactions such as fever, hives, breathing problems and so on.
The precautions that should be taken while taking antibiotics are:
- Overdose of antibiotics should not be taken
- Antibiotics should not be taken on an empty stomach

What is antibiotic resistant
Antibiotic resistance is a situation that occurs when antibiotic has lost its ability to effectively kill or control bacterial growth. In other words the bacteria become resistant and they continue to multiply in the presence of an antibiotic. Though some bacteria are naturally resistant to few antibiotics, there are others which become resistant in either ways such as by acquiring resistance from another bacterium or by a genetic mutation.
Important things to know
- If you are prescribed with antibiotics then you must follow the dose properly. Always complete the dose and never take more than the dose prescribed. If you do not complete the course of your antibiotics than the bacteria causing the infection becomes resistant to that antibiotic.
