|clinicalTrials=* Most adverse reactions to benzodiazepines, including CNS effects and [[respiratory depression]] are dose dependent, with more severe effects occurring with high doses.
|alcohol=Alcohol-Lorazepam (oral) interaction has not been established. Talk to your doctor about the effects of taking alcohol with this medication.
 
* In a sample of about 3500 patients treated for [[anxiety]], the most frequent adverse reaction to lorazepam was [[sedation]] (15.9%), followed by [[dizziness]] (6.9%), [[weakness]] (4.2%), and unsteadiness (3.4%). The incidence of [[sedation]] and unsteadiness increased with age.
 
* Other adverse reactions to benzodiazepines, including lorazepam are [[fatigue]], [[drowsiness]], [[amnesia]], memory impairment, [[confusion]], [[disorientation]], [[depression]], unmasking of [[depression]], [[disinhibition]][, [[euphoria]], [[suicidal ideation]]/attempt, [[ataxia]], [[asthenia]], [[extrapyramidal symptoms]], [[convulsions]]/[[seizures]] [[tremor]], [[vertigo]], eye-function/[[visual disturbance]] (including [[diplopia]] and [[blurred vision]]), [[dysarthria]]/[[slurred speech]], change in [[libido]], [[impotence]], decreased orgasm; [[headache]], [[coma]]; [[respiratory depression]], [[apnea]], worsening of [[sleep apnea]], worsening of [[obstructive pulmonary disease]]; gastrointestinal symptoms including [[nausea]], change in appetite, [[constipation]], [[jaundice]], increase in bilirubin, increase in liver transaminases, increase in alkaline phosphatase; [[hypersensitivity|hypersensitivity reactions]], [[anaphylactic]]/oid reactions; dermatological symptoms, [[allergy|allergic skin reactions]], [[alopecia]]; [[SIADH]], [[hyponatremia]]; [[thrombocytopenia]], [[agranulocytosis]], [[pancytopenia]]; [[hypothermia]]; and autonomic manifestations.
 
* Paradoxical reactions, including [[anxiety]], excitation, [[agitation]], hostility, aggression, rage, sleep disturbances/[[insomnia]], sexual arousal, and [[hallucinations]] may occur. Small decreases in blood pressure and [[hypotension]] may occur but are usually not clinically significant, probably being related to the relief of [[anxiety]] produced by lorazepam.
|postmarketing=There is limited information regarding <i>Postmarketing Experience</i> of {{PAGENAME}} in the drug label.
|drugInteractions=* The benzodiazepines, including lorazepam, produce increased CNS-depressant effects when administered with other CNS depressants such as alcohol, barbiturates, [[antipsychotics]], [[sedative]]/[[hypnotics]], [[anxiolytics]], [[antidepressants]], narcotic analgesics, [[sedative]] [[antihistamines]], [[anticonvulsants]], and anesthetics.
 
* Concomitant use of clozapine and lorazepam may produce marked [[sedation]], excessive [[salivation]], [[hypotension]], [[ataxia]], [[delirium]], and respiratory arrest.
 
* Concurrent administration of lorazepam with valproate results in increased plasma concentrations and reduced clearance of lorazepam. Lorazepam dosage should be reduced to approximately 50% when coadministered with valproate.
 
* Concurrent administration of lorazepam with probenecid may result in a more rapid onset or prolonged effect of lorazepam due to increased half-life and decreased total clearance. Lorazepam dosage needs to be reduced by approximately 50% when coadministered with probenecid.
 
* The effects of probenecid and valproate on lorazepam may be due to inhibition of glucuronidation.
 
* Administration of theophylline or aminophylline may reduce the sedative effects of benzodiazepines, including lorazepam.

|overdose=* In postmarketing experience, overdose with lorazepam has occurred predominantly in combination with alcohol and/or other drugs. Therefore, in the management of overdosage, it should be borne in mind that multiple agents may have been taken.
Symptoms
 
* Overdosage of benzodiazepines is usually manifested by varying degrees of central nervous system depression ranging from drowsiness to coma. In mild cases, symptoms include drowsiness, mental confusion, paradoxical reactions, dysarthria and lethargy. In more serious cases, and especially when other drugs or alcohol were ingested, symptoms may include ataxia, hypotonia, hypotension, cardiovascular depression, respiratory depression, hypnotic state, coma, and death.
 
'''MANAGEMENT'''
 
* General supportive and symptomatic measures are recommended; vital signs must be monitored and the patient closely observed. When there is a risk of aspiration, induction of emesis is not recommended. Gastric lavage may be indicated if performed soon after ingestion or in symptomatic patients. Administration of activated charcoal may also limit drug absorption. Hypotension, though unlikely, usually may be controlled with norepinephrine bitartrate injection. Lorazepam is poorly dialyzable. Lorazepam glucuronide, the inactive metabolite, may be highly dialyzable.
 
* The benzodiazepine antagonist flumazenil may be used in hospitalized patients as an adjunct to, not as a substitute for, proper management of benzodiazepine overdose. The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users and in cyclic antidepressant overdose.

Overview

Lorazepam (oral) is an antianxiety drug that is FDA approved for the treatment of anxiety disorders, status epilepticus, insomnia and as premedication for anesthetic procedure. Common adverse reactions include fatigue, drowsiness, amnesia, confusion, disorientation, depression, euphoria, ataxia, asthenia, tremor, and vertigo.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Indications

  • Lorazepam is indicated for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety or anxiety associated with depressive symptoms. Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic.
  • The effectiveness of lorazepam in long-term use, that is, more than 4 months, has not been assessed by systematic clinical studies. The physician should periodically reassess the usefulness of the drug for the individual patient.

Dosage

  • Lorazepam is administered orally. For optimal results, dose, frequency of administration, and duration of therapy should be individualized according to patient response. To facilitate this, 0.5 mg, 1 mg, and 2 mg tablets are available.
  • The usual range is 2 to 6 mg/day given in divided doses, the largest dose being taken before bedtime, but the daily dosage may vary from 1 to 10 mg/day.
  • For anxiety, most patients require an initial dose of 2 to 3 mg/day given b.i.d. or t.i.d.
  • For insomnia due to anxiety or transient situational stress, a single daily dose of 2 to 4 mg may be given, usually at bedtime.
  • For elderly or debilitated patients, an initial dosage of 1 to 2 mg/day in divided doses is recommended, to be adjusted as needed and tolerated.
  • The dosage of lorazepam should be increased gradually when needed to help avoid adverse effects. When higher dosage is indicated, the evening dose should be increased before the daytime doses.
