Benzodiazepines f

l CONTRA-INDICATIONS Acute pulmonary insufficiency . marked neuromuscular respiratory weakness . sleep

apnoea syndrome . unstable myasthenia gravis

l CAUTIONS Avoid prolonged use (and abrupt withdrawal

thereafter). debilitated patients (reduce dose)(in adults).

elderly (reduce dose). history of alcohol dependence or

abuse . history of drug dependence or abuse . myasthenia

gravis . personality disorder (within the fearful group—

dependent, avoidant, obsessive-compulsive) may increase

risk of dependence .respiratory disease

CAUTIONS, FURTHER INFORMATION

▶ Paradoxical effects A paradoxical increase in hostility and

aggression may be reported by patients taking

benzodiazepines. The effects range from talkativeness and

excitement to aggressive and antisocial acts. Adjustment

of the dose (up or down) sometimes attenuates the

impulses. Increased anxiety and perceptual disorders are

other paradoxical effects.

l SIDE-EFFECTS

▶ Common or very common Alertness decreased . anxiety . ataxia (more common in elderly). confusion (more

common in elderly). depression . dizziness . drowsiness . dysarthria . fatigue . gastrointestinal disorder. headache . hypotension . mood altered . muscle weakness . nausea . respiratory depression (particularly with high dose and

intravenous use—facilities for its treatment are essential). sleep disorders . suicidal ideation .tremor. vertigo . vision

disorders . withdrawal syndrome

▶ Uncommon Agitation (more common in children and

elderly). anterograde amnesia . behaviour abnormal . hallucination . libido disorder.rash . urinary disorders

▶ Rare or very rare Aggression (more common in children

and elderly). blood disorder. delusions . jaundice . paradoxical drug reaction . psychosis

▶ Frequency not known Drug dependence

Overdose Benzodiazepines taken alone cause drowsiness,

ataxia, dysarthria, nystagmus, and occasionally respiratory

depression, and coma. For details on the management of

poisoning, see Benzodiazepines, under Emergency

treatment of poisoning p. 1359.

l PREGNANCY Risk of neonatal withdrawal symptoms when

used during pregnancy. Avoid regular use and use only if

there is a clear indication such as seizure control. High

doses administered during late pregnancy or labour may

cause neonatal hypothermia, hypotonia, and respiratory

depression.

l HEPATIC IMPAIRMENT In general, manufacturers advise

caution in mild to moderate impairment; avoid in severe

impairment. Benzodiazepines with a shorter half-life are

considered safer.

Dose adjustments In general, manufacturers advise dose

reduction in mild to moderate impairment, adjust dose

according to response.

l RENAL IMPAIRMENT Increased cerebral sensitivity to

benzodiazepines.

l PATIENT AND CARER ADVICE

Driving and skilled tasks May cause drowsiness, impair

judgement and increase reaction time, and so affect ability

to drive or perform skilled tasks; effects of alcohol

increased. Moreover the hangover effects of a night dose

may impair performance on the following day.

For information on 2015 legislation regarding driving

whilst taking certain controlled drugs, including

benzodiazepines, see Drugs and driving under Guidance on

prescribing p. 1.

risk extends to at least 24 hours after administration.

Responsible persons should be available to take patients

home afterwards. The dangers of taking alcohol should be

emphasised.
