Antibiotics are used to treat infections caused by bacteria. They have
no effect against infections caused by viruses.
Sometimes an infection caused by bacteria does not respond to a
course of an antibiotic. One of the commonest reasons for this to
occur is because the bacteria causing the infection are resistant to the
antibiotic that is being taken. This means that they can survive and
even multiply despite the antibiotic.
Bacteria can become resistant to antibiotics for many reasons.
Using antibiotics carefully can help to reduce the chance of bacteria
becoming resistant to them.
When your doctor prescribes a course of an antibiotic it is intended to
treat only your current illness. Paying attention to the following advice
will help prevent the emergence of resistant bacteria that could stop
the antibiotic working.
1. It is very important that you take the antibiotic at the right dose,
at the right times and for the right number of days. Read the
instructions on the label and if you do not understand anything ask
your doctor or pharmacist to explain.
2. You should not take an antibiotic unless it has been prescribed
specifically for you and you should use it only to treat the infection
for which it was prescribed.
3. You should not take antibiotics that have been prescribed for other
people even if they had an infection that was similar to yours.
4. You should not give antibiotics that were prescribed for you to other
5. If you have any antibiotic left over when you have taken the course
as directed by your doctor you should take the remainder to a
pharmacy for appropriate disposal.
9. Keeping the end of the needle in the liquid, pull back the plunger and draw
all the liquid in the vial into the syringe.
10. Remove the needle and syringe from the vial and throw the empty vial
away in a safe place.
11. Hold the syringe upright, with the needle pointing upwards. Tap the syringe
so that any bubbles in the liquid rise to the top of the syringe.
12. Remove any air in the syringe by gently pushing the plunger until all the air
13. If you are using Meropenem at home, dispose of any needles and infusion
lines that you have used in an appropriate way. If your doctor decides to
stop treatment, dispose of any unused Meropenem in an appropriate way.
