Superbugs are strains of bacteria, viruses, parasites and fungi that are resistant to most of the antibiotics and other medications commonly used to treat the infections they cause. A few examples of superbugs include resistant bacteria that can cause pneumonia, urinary tract infections and skin infections.

While antibiotics don't treat most colds, which come from viral infections, they do treat strep throat, as it's caused by streptococcus bacteria.

When discussing antibiotic duration with patients, rather than simply applying a blanket statement, a more tailored approach?

When discussing antibiotic duration with patients, rather than simply applying a blanket statement, a more tailored approach considering the patient, reason for antibiotics and prescribed duration compared to best available evidence is needed. Some experts have suggested counselling the patient to contact his or her prescriber if symptoms have improved prior to completing the course in order to discuss the possibility of an abbreviated course.6As always, patients should be instructed not to share or save antibiotics for later use and to return any unused antibiotics to the pharmacy for disposal.

How long should antibiotics be given?

Most clinicians tend to prescribe a fixed duration of antibiotic therapy (e.g., 7, 10, 14 days) for common community-acquired bacterial infections, without taking into account the patient’s clinical response. However, as more data informing duration of therapy accumulate, clinicians are learning that short courses of antibiotics are usually equally effective (in terms of clinical cure and relapse) as longer courses for most common uncomplicated infections treated in the community setting.6Recent clinical trials have challenged the dogma that antibiotic therapy cannot be stopped earlier. Studies show that for community-acquired pneumonia, 5 days are as good as 7 to 107; for pyelonephritis, 7 days are as good as 10 to 148; and for cellulitis, 5 days are as good as 10.9It should be noted, however, that there are some exceptions where longer courses may be preferred: streptococcal pharyngitis10and otitis media in children under 2 years11may require longer courses of treatment, as do deep-seated or chronic infections.12,13Also, there is limited evidence examining duration of treatment for infections occurring in severely immunocompromised patients. Regardless, shorter courses of antibiotics can be safely used for the majority of uncomplicated community-acquired infections.

Why do pharmacists help with antibiotics?

As trusted health care professionals, pharmacists are in a unique position to help fight antimicrobial resistance and improve patient safety by dispelling the myth that “more is always better” when it comes to antibiotics.

What does Fleming say about antibiotics?

In his Nobel lecture, Fleming spoke of a hypothetical situation where a person self-treats a sore throat with antibiotics, “He buys some penicillin and gives himself, not enough to kill the streptococci but enough to educate them to resist penicillin.” He advised, “If you use penicillin, use enough.”1Although he was likely alluding to the risks of inadequate dosing, his quote has been construed to mean that inadequate durations of antibiotic therapy breed resistance. This belief, coupled with the underestimated risks of antibiotics and commercial disincentives to use less antibiotics, has shaped modern-day thinking about antibiotics. In fact, “finish the course” is based on 2 ideas about shorter courses of antibiotics that are unsupported by current evidence: 1) they are less effective, and 2) they lead to more resistance.

Can antibiotics cause resistance?

Most of us were taught that terminating antibiotics prematurely can lead to the development of bacterial resistance. This has proven to be a myth as mounting evidence supports the opposite. In fact, it is prolonged exposure to antibiotics that provides the selective pressure to drive antimicrobial resistance; hence, longer courses are more likely to result in the emergence of resistant bacteria.14,15Additionally, long durations of therapy put patients at increased risk for adverse effects,16,17including the development of Clostridium difficileinfection,18which is associated with significant morbidity and mortality.

Is the finish the course message counterproductive?

A recent commentary by Llewelyn et al.19echoes the concept that the “finish the course” message is counterproductive to antibiotic ste wardship. While acknowledging that further research is needed to determine the optimal duration of treatment for many infections, the authors encourage policy makers, educators and physicians to drop the “finish the course” message in favour of emphasizing the harms of antibiotic overuse and a shift towards more patient-centred decision making.

Is it outdated to tell every patient to finish the course of antibiotics?

It is clear that telling every patient to “finish the course of antibiotic therapy , even if you feel better” is outdated.
