Antibiotics: why must they not be used at random?

What are we talking about?

Antibiotics treat certain bacterial infections. They are ineffective against most colds, influenzas and other common viral infections.

WHO warns about antimicrobial resistance (AMR): when bacteria adapt, antibiotics become less effective for everyone.

What you may observe

A febrile symptom, a cough or diarrhoea does not “prove” that an antibiotic is needed. Only a professional assessment can decide.

If an antibiotic has been prescribed for you, note the exact duration and schedule.

Good practices

Use an antibiotic only if it has been prescribed for the current episode. Respect the indicated times and duration.

When treatment has been prescribed, finish the course as indicated, unless the prescriber gives explicit contrary instructions. Do not keep leftovers “for next time”.

What to avoid

Avoid using leftover antibiotics from an old box, those of a relative, or buying them without assessment.

Avoid stopping a prescribed course too early because “it feels better”, unless advised by the professional following the treatment.

Medicines: what you need to know

Each antibiotic has its own spectrum and precautions (allergies, interactions, pregnancy, renal impairment).

In case of an adverse effect or a missed dose, ask for advice rather than adjusting the dosage on your own.

When to ask the pharmacist?

The pharmacist recalls how to take the medicine, any food precautions, and the importance of not sharing the treatment.

They can also explain why an antibiotic is not indicated in your current situation.

When to seek medical care?

Seek care if symptoms worsen, if an allergic reaction appears, or if the infection for which the antibiotic was prescribed does not improve as expected.
