INTRODUCTION
Antimicrobial resistance is recognised as a significant threat to public health by compromising our ability to treat infections effectively.
It is widely acknowledged that antibiotic resistance is driven by high rates of antibiotic prescribing.
The continuing problem of antimicrobial resistance has prompted efforts to reduce unnecessary antibiotic use to maximise the lifespan of
these valuable drugs and to strive to prevent a return to the “pre-antibiotic” era.
It is estimated that 80% of all antibiotics consumed by patients are prescribed by general practitioners.
It was established in 2008 that Ireland had relatively high rates of antibiotic prescribing compared to our European counterparts, and one
of only three countries in Europe that community antibiotic consumption was continuing to increase, and in addition had relatively
high levels of “broad spectrum” antibiotic use. - Source - ESAC
Penicillin non-susceptible Streptococcus pneumoniae (PNSP) is a “marker organism” and key indicator of antibiotic resistance in primary
care. In Ireland, non-susceptibility rates to penicillin for this organism have increased from 10.3% in 2004 to 18.2% in 2010.* (See
Europe map on page 3).
Rates of quinolone resistance in E.Coli in Ireland has increased from 5.2% in 2002 to 23.6% in 2010.*
Evidence-based antimicrobial guidelines are a key tool in efforts to improve antibiotic prescribing, reduce the progression of antibiotic
resistance and optimise patient outcomes.
These guidelines have been developed as part of the Strategy for the Control of Antimicrobial Resistance in Ireland (SARI) initiative
which has been ongoing in Ireland since 2001.

Distribution of Penicillin non-susceptible Streptococcus pneumoniae (PNSP) which is a marker for community resistance in Europe
in 2009 (European Antimicrobial Resistance Surveillance Network (EARS-Net))
Aims
to provide a simple, best guess approach to the treatment of common infections
to promote the safe and effective use of antibiotics
to minimise the emergence of bacterial resistance in the community
Principles of Treatment
1. This guidance is based on the best available evidence but its application must be modified by professional judgement.
2. A dose and duration of treatment is suggested. In severe or recurrent cases consider a larger dose or longer course
3. Prescribe an antibiotic only when there is likely to be a clear clinical benefit.
4. Consider a no, or delayed, antibiotic strategy for acute sore throat, common cold, acute cough and acute sinusitis.
5. Limit prescribing over the telephone to exceptional cases.
6. Try to avoid over-use of broad spectrum antibiotics (eg co-amoxiclav, quinolones and cephalosporins) as this can increase
risk of PNSP, Clostridium difficile, MRSA and resistant UTIs and also limit the future usefulness of these important agents.
Consider use of narrow spectrum agents (e.g. penicillin, amoxicillin, flucloxacillin, trimethoprim) as outlined in these
guidelines for specific indications where clinically appropriate. In particular, try to reserve use of cephalosporins and quinolones
unless there is clear rationale (e.g. where guideline evidence recommends, true allergy with little alternative, specific indication
for agent, and/or based on sensitivity results).
7. Note: Hospital antibiotic guidelines can differ from community guidelines as patients are generally systemically unwell when
hospitalised and may require intravenous and/or broader spectrum agents due to possible recent exposure to antibiotics in the
community and/or failed initial therapy and increased severity of illness.
8. Avoid widespread use of topical antibiotics (especially those agents also available as systemic preparations, e.g. fusidic acid).
9. In pregnancy AVOID tetracyclines, aminoglycosides, quinolones and high dose metronidazole (2g). Short-term use of
trimethoprim (unless low folate status or taking another folate antagonist such as antiepileptic or proguanil) or nitrofurantoin (at
term, theoretical risk of neonatal haemolysis) is unlikely to cause problems to the foetus.
10. Clarithromycin has fewer side-effects than erythromycin. However, erythromycin is preferable to clarithromycin if patient is on
warfarin. Clarithromycin has a greater potential for raising INR. Note, spectrum of activities of these drugs not identical.
Exercise caution when considering concomitant administration of macrolides and statin therapy due to potential risk of
rhabdomyolysis.
11. Where a „best guess‟ therapy has failed or special circumstances exist, seek microbiological advice.

patients do not benefit from antibiotics.
Consider a delayed antibiotic strategy and explain
soreness will take about 8 days to resolve. Patients
with 3 of 4 centor criteria (history of fever, purulent
tonsils, cervical adenopathy, absence of cough) or

NNoottee::. Amoxicillin resistance is common, therefore ONLY use if culture confirms susceptibility. In the elderly (>65 years), do not treat asymptomatic bacteriuria; it occurs in 25%
of women and 10% of men and is not associated with increased morbidity.B+

For first presentations, low risk of resistant organisms in uncomplicated UTI
consider narrow-spectrum antibiotics that concentrate in the bladder such as
trimethoprim or nitrofurantoin in the first instance.

Panton-Valentine Leukocidin (PVL) is a toxin produced by 2% of Staphylococcus aureus and is associated with persistent recurrent pustules and carbuncles or cellulitis. Send swabs for
culture in these clinical scenarios. On rare occasions it causes more severe invasive infections, even in otherwise fit people. Risk factors include: nursing homes, contact sports, sharing
equipment, poor hygiene and eczema.
Acne vulgaris Topical treatment first line e.g. benzoyl peroxide gel, retinoid or topical antibiotic.
Avoid using topical and oral antibiotics concurrently. However, topical benzoyl

Trimethoprim: : trimethoprim is a folate antagonist. Folate supplementation during the first trimester reduces the risk of neural tube defects in offspring of pregnant women treated with trimethoprim.
In women with normal folate status, who are well nourished, trimethoprim is unlikely to cause folate deficiency. However, it should not be used by women with established folate deficiency or low
dietary folate intake, or by women taking other folate antagonists (e.g. antiepileptic drugs or proguanil).
Nitrofurantoin: : significant placental transfer of nitrofurantoin does not occur. Nitrofurantoin has not been associated with an increased risk of congenital malformations. Nitrofurantoin has been
associated with haemolysis in people with glucose-6-phosphate dyhydrogenase (G6PD) deficiency. However, the risk seems very small because placental transfer is so low. There is only one reported
case of haemolytic anaemia in a newborn whose mother was treated at term with nitrofurantoin.

Issue 3, Art No. CD001209. DOI: 10.1002/14651858.CD001209.pub2. http://www.mrw.interscience.wiley.com/cochrane/clsysrev/articles/CD001209/frame.html This is an excellent review of
prophylaxis. It shows that it is very effective (NNT2). However 30% do not comply. Benefit lost as soon as prophylaxis stops and prophylaxis after intercourse is as effective as daily prophylaxis.

Data on the outcomes of over 1,700 pregnancies exposed to low-dose fluconazole (150 mg stat) show no increased incidence of spontaneous abortions, malformations, or patterns of defects. However,
there may be an increased risk of malformations associated with high-dose chronic therapy (>400 mg/day). First-line treatment of candidal infection in pregnancy should be with an imidazole.
However, fluconazole (150mg stat) may be a suitable second-line treatment if clotrimazole is ineffective.

Prescribing for children
Weight and height
The table below shows the mean values for weight and height by age;
these values may be used to calculate doses in the absence of actual
measurements. However, the child‟s actual weight and height might
vary considerably from the values in the table and it is important to see
the child to ensure that the value chosen is appropriate.
In most cases the child‟s actual measurement should be obtained
as soon as possible and the dose re-calculated. (Adapted from BNF for children 2006)
