patients with renal impairment or solid-organ

transplants as they are at a higher risk of tendon injury.

l CONTRA-INDICATIONS History of tendon disorders related

to quinolone use

l CAUTIONS Can prolong the QT interval . children or

adolescents (arthropathy has developed in weight-bearing

joints in young animals) (in children). conditions that

predispose to seizures . diabetes (may affect blood glucose) . exposure to excessive sunlight should be avoided

(discontinue if photosensitivity occurs).G6PD deficiency . history of epilepsy . myasthenia gravis (risk of

exacerbation)

CAUTIONS, FURTHER INFORMATION

▶ Use in children Quinolones cause arthropathy in the

weight-bearing joints of immature animals and are

therefore generally not recommended in children and

growing adolescents. However, the significance of this

effect in humans is uncertain and in some specific

circumstances short-term use of ciprofloxacin may be

justified in children.

completion of treatment). hypoglycaemic coma . increased

risk of aortic aneurysm (more common in elderly). increased risk of aortic dissection (more common in

elderly). ligament rupture .rhabdomyolysis (in adults). self-endangering behaviour

SIDE-EFFECTS, FURTHER INFORMATION The drug should be

discontinued if neurological, psychiatric, tendon disorders

or hypersensitivity reactions (including severe rash) occur.

For more information regarding the safety of

fluoroquinolones, please see Important Safety

Information.

l ALLERGY AND CROSS-SENSITIVITY Use of quinolones

contra-indicated in quinolone hypersensitivity.

l PREGNANCY Avoid in pregnancy—shown to cause

arthropathy in animal studies; safer alternatives are

available.

l PATIENT AND CARER ADVICE The MHRA has produced an

advice sheet on serious adverse reactions affecting

musculoskeletal and nervous systems associated with

fluoroquinolone use, which should be provided to patients

l NATIONAL FUNDING/ACCESS DECISIONS

Scottish Medicines Consortium (SMC) decisions

The Scottish Medicines Consortium has advised (August

2016) that levofloxacin (Quinsair ®) is accepted for

restricted use within NHS Scotland for the management of

chronic pulmonary infections due to Pseudomonas

aeruginosa in patients with cystic fibrosis, as a third-line

treatment option after colistimethate sodium (first line)

and tobramycin (second line). This advice is contingent

upon the continuing availability of the Patient Access

Scheme in NHS Scotland or a list price that is equivalent or

lower.

All Wales Medicines Strategy Group (AWMSG) decisions

The All Wales Medicines Strategy Group has advised

(November 2016) that levofloxacin (Quinsair ®) is

recommended as an option for restricted use within NHS

Wales as third-line therapy for the management of chronic

pulmonary infections due to Pseudomonas aeruginosa in

patients with cystic fibrosis, who do not respond to, or are

intolerant of, second-line treatment with tobramycin, only

if the approved Wales Patient Access Scheme (WPAS) is

used or where the list price is equivalent or lower.

IMPORTANT SAFETY INFORMATION

RESTRICTIONS ON THE USE OF CO-TRIMOXAZOLE

Co-trimoxazole is the drug of choice in the prophylaxis

and treatment of Pneumocystis jirovecii (Pneumocystis

carinii) pneumonia; it is also indicated for nocardiasis,

Stenotrophomonas maltophilia infection [unlicensed

indication], and toxoplasmosis. It should only be

considered for use in acute exacerbations of chronic

bronchitis and infections of the urinary tract when there

is bacteriological evidence of sensitivity to cotrimoxazole and good reason to prefer this combination

to a single antibacterial; similarly it should only be used

in acute otitis media in children when there is good

reason to prefer it. Co-trimoxazole is also used for the

treatment of infections caused by Burkholderia cepacia in

cystic fibrosis [unlicensed indication].

l CONTRA-INDICATIONS Acute porphyrias p. 1058

l CAUTIONS Asthma . avoid in blood disorders (unless under

specialist supervision). avoid in infants under 6 weeks

(except for treatment or prophylaxis of pneumocystis

pneumonia) because of the risk of kernicterus . elderly

(increased risk of serious side-effects).G6PD deficiency

(risk of haemolytic anaemia). maintain adequate fluid

intake . predisposition to folate deficiency . predisposition

to hyperkalaemia

l INTERACTIONS → Appendix 1: sulfonamides .trimethoprim

l SIDE-EFFECTS

▶ Common or very common Diarrhoea . electrolyte imbalance . fungal overgrowth . headache . nausea . skin reactions

SIDE-EFFECTS, FURTHER INFORMATION Co-trimoxazole is

associated with rare but serious side effects. Discontinue

immediately if blood disorders (including leucopenia,

thrombocytopenia, megaloblastic anaemia, eosinophilia)

or rash (including Stevens-Johnson syndrome or toxic

epidermal necrolysis) develop.

l PREGNANCY Teratogenic risk in first trimester

(trimethoprim a folate antagonist). Neonatal haemolysis

and methaemoglobinaemia in third trimester; fear of

increased risk of kernicterus in neonates appears to be

unfounded.

l BREAST FEEDING Small risk of kernicterus in jaundiced

infants and of haemolysis in G6PD-deficient infants (due

to sulfamethoxazole).

l HEPATIC IMPAIRMENT Manufacturer advises avoid in

severe liver disease.

l RENAL IMPAIRMENT

▶ In adults Avoid if eGFR less than 15 mL/minute/1.73 m2 and

if plasma-sulfamethoxazole concentration cannot be

monitored.

▶ In children Avoid if estimated glomerular filtration rate less

than 15 mL/minute/1.73 m2 and if plasmasulfamethoxazole concentration cannot be monitored.
