Do you need to take all your antibiotics?

Can antibiotics cause diarrhoea?

Antibiotic-resistant bacteria include Clostridium difficile, which can be carried harmlessly in the bowel until a course of antibiotics kills off its competition. This allows it to multiply and produce toxins, potentially causing life-threatening diarrhoea.

Is antibiotic resistance proportional to antibiotics?

The rate of antibiotic resistance (in a community, a hospital or a whole country) is proportional to the total amount of antibiotics used. The relationship is complex but the dangerous increase in multidrug-resistant bacteria has led some experts to predict the “end of the antibiotic era”. This is the downside of 75 years of antibiotic therapy.
