Step 1
Do not prescribe fluoroquinolone / antibiotics for mild infections because they will get better due to the body's normal immune system.
Answer
It’s essential to refrain from prescribing fluoroquinolone or any antibiotics for mild infections. The body's immune system is capable of handling these infections without the aid of antibiotics, which helps prevent unnecessary resistance.
Step 2
Do not prescribe fluoroquinolone / antibiotics for viral infections / colds / flu because antibiotics do not kill viruses.
Answer
Antibiotics, including fluoroquinolone, are ineffective against viral infections such as colds or flu. Prescribing them in such cases would not only be futile but would also contribute to antibiotic resistance.
Step 3
If you do prescribe fluoroquinolone / antibiotics make sure the patient finishes the course.
Answer
It's crucial for healthcare providers to instruct patients to complete their antibiotic courses. This ensures that all bacteria are eradicated, reducing the chance of resistance development.
Step 4
Do not prescribe fluoroquinolone if the patient has the new strain because their routine use would lead to an increase in resistant bacteria.
Answer
Avoiding the prescription of fluoroquinolone for patients with the new strain is vital, as its continued use will lead to increased antibiotic resistance.
Step 5
Doctors and nurses in the practice / hospital should be using strict hygiene procedures between each patient and / or isolate (resistant) bacteria.
Answer
Implementing stringent hygiene measures between patients is crucial in preventing the spread of infections. Isolation of known resistant bacteria can further protect other patients.
