Antibiotics are powerful, lifesaving medications that treat bacterial infections like strep throat and urinary tract infections. But they're not for every sickness, and they can cause side effects like diarrhea. Learning when you need antibiotics and how to take them properly can help you benefit from these medications with the least risk.
Antibiotics fight bacteria that cause strep throat and ear, sinus and urinary infections. They do not work for the flu, colds, coughs and sore throats. Consult with your doctor about your symptoms, which can help determine the origin of your illness. Ask your doctor about the benefits and drawbacks of taking antibiotics for your diagnosis.
Pros of taking antibiotics:
● Antibiotics can slow the growth of and kill many types of infection.
● In some cases, such as before surgery, antibiotics can prevent infection from occurring.
● Antibiotics are fast-acting; some will begin working within a few hours.
● They are easy to take: Most antibiotics are oral medications. Your doctor may decide to give you an injection, if it is imperative that the medicine gets into your system quickly.
What Do Antibiotics Treat?
Antibiotics only treat certain bacterial infections, such as strep throat, urinary tract infections, and E. coli.
You may not need to take antibiotics for some bacterial infections. For example, you might not need them for many sinus infections or some ear infections. Taking antibiotics when they're not needed won't help you, and they can have side effects. Your health care provider can decide the best treatment for you when you're sick. Don't ask your provider to prescribe an antibiotic for you.
This complicated question, which should be answered by your healthcare provider, depends on the specific diagnosis. For example, there are several types of ear infections—most need antibiotics, but some do not. Most cases of sore throat are caused by viruses. One kind, strep throat, diagnosed by a lab test, needs antibiotics.
Common viral infections, like coughs or a cold, can sometimes become complicated and a bacterial infection can develop. However, treating viral infections with antibiotics in order to prevent bacterial infections is not recommended because of the risk of causing bacterial resistance:
● Remember that antibiotics do not work against viral colds and the flu, and that unnecessary antibiotics can be harmful.
● Talk with your healthcare provider about antibiotics and find out about the differences between viruses and bacteria, and when antibiotics should and should not be used.
● If your child receives an antibiotic, be sure to give it exactly as prescribed to decrease the development of resistant bacteria. Have your child finish the entire prescription. Don't stop when the symptoms of infection go away.
● Never save the left over antibiotics to use "just in case." This practice can also lead to bacterial resistance.
● Do not share your antibiotics with someone else or take an antibiotic that was prescribed for someone else.
● Antibiotic resistance is a problem in both children and adults.
Remember that taking antibiotics appropriately and making sure your child receives the proper immunizations will help prevent having to take more dangerous and more costly medicines. Talk with your healthcare provider for more information.

People usually take antibiotics by mouth. However, doctors can administer them by injection or apply them directly to the part of the body with infection.
Most antibiotics can start working within a few hours. Doctors advise people to complete the whole course of medication to prevent the return of the infection.
Stopping the medication before the course has finished increases the risk that the bacteria will become resistant to future treatments. The ones that survive will have had some exposure to the antibiotic and may consequently develop resistance to it.
An individual needs to complete the course of antibiotic treatment even after they notice an improvement in symptoms.
Doctors and the leaflet provided with the drug provide specific instructions on how to take the medication correctly.
People can follow some tips for using antibioticsTrusted Source effectively, such as:
● Avoiding alcohol when using metronidazole.
● Avoiding dairy products when taking tetracyclines, as these might disrupt the absorption of the medication.
● Taking the medication at the same time, or at set times in the day — this depends on how many times a day a person needs to take the drug.
There are hundreds of different types of antibiotics, but most of them can be classified into 6 groups.
Penicillins (such as penicillin, amoxicillin, co-Amoxiclav, flucloxacillin and phenoxymethylpenicillin) – widely used to treat a variety of infections, including skin infections, chest infections and urinary tract infections.
Cephalosporins (such as cefalexin) – Used to treat a wide range of infections, but some are also effective for treating more serious infections, such as sepsis and meningitis.
Aminoglycosides (such as gentamicin and tobramycin) – Tend to only be used in hospital to treat very serious illnesses such as sepsis, as they can cause serious side effects, including hearing loss and kidney damage; they're usually given by injection, but may be given as drops for some ear or eye infections.
Tetracyclines (such as tetracycline, doxycycline and lymecycline) – Can be used to treat a wide range of infections, but are commonly used to treat acne and a skin condition called rosacea.
Macrolides (such as azithromycin, erythromycin and clarithromycin) – Can be particularly useful for treating lung and chest infections, or as an alternative for people with a penicillin allergy, or to treat penicillin-resistant strains of bacteria.
Fluoroquinolones (such as ciprofloxacin and levofloxacin) – Are broad-spectrum antibiotics that were once used to treat a wide range of infections, especially respiratory and urinary tract infections; these antibiotics are no longer used routinely because of the risk of serious side effects.
Other antibiotics include chloramphenicol (used for eye and ear infections), fusidic acid (used for skin and eye infections), and nitrofurantoin and trimethoprim (used for urinary tract infections).
How Long Does It Take for Antibiotics to Work?
When you take antibiotics, they start working right away. But how long it takes for you to feel better depends on what kind of infection you have and how bad it is. Usually, you'll start feeling better within a few days, but it might take up to 2 weeks for some infections.
Even if you start feeling better before you finish all your medicine, it's important to keep taking it until it's all gone. This helps make sure all the bacteria are killed off so you don't get sick again.
You shouldn't take antibiotics for viral infections. Antibiotics target bacteria, not viruses. So, they won't work against conditions like:
● The flu.
● A common cold or runny nose.
● Most instances of bronchitis.
● A sore throat (unless it's strep throat).
● A sinus infection caused by a virus.
You likely don't need antibiotics for some bacterial infections that typically go away on their own. These include:
● Some sinus infections caused by bacteria.
● Some ear infections.
● Your healthcare provider will tell you if you need antibiotics for these common infections.

Antibiotics work by blocking vital processes in bacteria. They kill the bacteria or stop it from spreading. This helps the body's natural immune system to fight the infection. There are many types of antibiotics. They work against different types of bacteria.
● Some antibiotics affect a wide range of bacteria. They are called broad spectrum antibiotics (eg, amoxicillin and gentamicin).
● Some antibiotics affect only a few types of bacteria. They are narrow spectrum antibiotics (eg, penicillin).
There are many types of antibiotics. Not all of them work in the same way. For instance, penicillin destroys bacterial cell walls. Other antibiotics can affect the way the cell works.
Doctors choose an antibiotic based on the bacteria that often cause a certain infection. Sometimes your doctor will do a test. This is to identify the exact type of bacteria causing your infection. It also checks how it reacts to certain antibiotics.
How Should I Store My Antibiotics in Hot Weather Conditions?
Most medicines should be stored at room temperature (around 20◦C). Most manufacturers suggest storing antibiotics below 25◦C. It is very important to read the labelling advice with regards to which temperature your antibiotics must be stored under. This is because some antibiotics lose their effectiveness when stored incorrectly and some may change form and become difficult to use.
Take a look at our tips for storing antibiotics in hot weather conditions:
● Not in the bathroom cabinet – bathrooms can be hot and humid, which could affect the stability of antibiotics.
● In the coolest and driest place of your house.
● Away from direct sunlight.
● Kept in original packaging and containers.
● Kept in airtight containers if it's humid.
● In an insulated bag if travelling in a car during hot days.
