Q : In which cases are antibiotics overprescribed? A : Overprescription of antibiotics is common. It usually occurs when a patient is treated for an infection from a virus that won’t benefit from antibiotics or when a patient is treated when there’s really no infection. For outpatients, the most common unnecessary antibiotics are for upper respiratory infections, which are almost always viruses. For hospital inpatients, treatment of false-positive urinary tract infection, which is usually caused by bacteria, is most common. Q : Is overprescription related to antibiotic resistance? A : Overprescription is a major cause of antibiotic resistance. However, appropriate use of antibiotics can also cause resistance. The major problem is that certain antibiotics don’t work anymore because the bacteria become resistant. Q : What should be done to tackle antibiotics overprescription, such as the overuse of antibiotics for false-positive urinary tract infections and for upper respiratory infections? A : Doctors need to know that there’s harm in using antibiotics and to avoid them if it’s unlikely there’s an infection. Patients need to know they’re often better off without an antibiotic. Antibiotics must always be given through prescription only and never over the counter. Overprescription is a major cause of antibiotic resistance Q : In which common cases can antibiotics be effectively replaced by other drugs? A : Mostly the issue isn’t around replacement for antibiotics but just not using them. Patients who have viral colds often feel better from ibuprofen and antihistamines, sometimes nasal saline irrigation. Antibiotics just make them more likely to have diarrhoea. Q : If antibiotics are necessary, how should they be taken? A : Antibiotics are amazing, lifesaving medications if used appropriately. They should be taken as directed, which varies for each disease. More and more studies are showing that short courses of antibiotics are often equivalent or better than long courses, but this varies by disease. Also, the guidance to always complete a course is wrong. It’s the equivalent of a wives tale that’s been passed along. A few years ago, research published in the British Medical Journal reviewed the lack of evidence for this. So, it’s always good to speak with your doctor about antibiotics but not unreasonable to stop them early if you’re feeling well.
