Traditionally, clinicians and health authorities advocate that patients should complete their full course of antibiotics as prescribed, even when their symptoms have improved, to prevent relapse of infection and the development of antibiotic resistance.
This means most probably that a virus has been responsible and viruses do not respond to antibiotics as all will know. Hence repeating the course will achieve little and may expose you to risk of side effects or secondary infection with something worse.
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.
Waiting too long between antibiotic doses increases the chance of bacteria growing and becoming resistant to the medicine. The following are examples of appropriate time intervals for taking your antibiotics. If your label says to use the medicine: Twice a day – take your dose every 12 hours.
It is usually taken every 12 hours (twice a day) or every 8 hours (three times a day) with or without food. The length of your treatment depends on the type of infection that you have.
Once the antibiotic treatment ends, the few remaining bacteria can grow again, restoring the infection. Infections that can't be treated are a significant problem.
Resistance to even one antibiotic can mean serious problems. For example: Antimicrobial-resistant infections that require the use of second- and third-line treatments can harm patients by causing serious side effects, such as organ failure, and prolong care and recovery, sometimes for months.
A growing body of research finds that telling patients to finish a full course of antibiotics even if they're already feeling better not only fails to prevent drug-resistant “superbugs” from forming, but also might make those pathogens stronger.
One way to fight a particularly stubborn infection is to prescribe two drugs at once that attack it in alternate ways—for example, two antibiotics can disrupt two different parts of the bacteria's protein-building machinery.
How long should antibiotics be taken for? Usually 3, 5 or 7 days – but it can be two weeks; and sometimes many weeks for long-term infections. Antibiotics should be taken for as long as the doctor has prescribed them. In fact, take them exactly as your doctor tells you, and they have been prescribed.
Antibiotics should be limited to an average of less than nine daily doses a year per person in a bid to prevent the rise of untreatable superbugs, global health experts have warned.
Vancomycin 3.0 is one of the most potent antibiotics ever created. It is used to treat conditions like methicillin-resistant Staphylococcus aureus-induced meningitis, endocarditis, joint infections, and bloodstream and skin infections.

Frequently Asked Questions. Will antibiotics continue to work after you stop taking them? Yes, antibiotics continue their antibacterial effects after your last dose. Some will last in the body longer than others.
Antibiotic resistance occurs when bacteria change so that antibiotic medicines can't kill them or stop their growth. As a result, bacterial infections become extremely difficult to treat. Antibiotic resistance is a type of antimicrobial resistance.
Antimicrobial resistance happens when germs like bacteria or fungi no longer respond to the drugs designed to kill them. That means these germs are not killed and continue to grow. It does not mean our body is resistant to antibiotics or antifungals. Antimicrobial resistance is a naturally occurring process.
Sometimes, bacteria causing infections are already resistant to prescribed antibiotics. Bacteria may also become resistant during treatment of an infection. Resistant bacteria do not respond to the antibiotics and continue to cause infection.
Every time you take antibiotics you are increasing the chances that next time you use that particular antibiotic, it won't work as effectively, says Dr Philippa Binns clinical advisor at NPS MedicineWise. You're also making it more likely that you could get infections that can't be properly treated.
You should always take all of your antibiotics as prescribed. Antibiotics should only be taken when prescribed by a doctor for a specific illness and should never be taken without speaking to your doctor or pharmacist – even if you feel sick in the future and think you may have the same illness!
Doctors should rely on science, not emotion
But many doctors prescribe higher dosages of antibiotics for longer courses than necessary or prescribe them for viral infections that can't be cured with antibiotics.
Long-term therapy was defined as an intended treatment course of greater than 12 months. Out of the 202 patients on long-term antibiotic therapy identified in this previous study, 29 patients were prescribed this therapy for infections deemed incurable [3,5].
Vancomycin, long considered a "drug of last resort," kills by preventing bacteria from building cell walls. It binds to wall-building protein fragments called peptides, in particular those that end with two copies of the amino acid D-alanine (D-ala).
