Lorazepam

Lorazepam tablets are 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 tablets 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.

• Lorazepam tablets are 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 two times a day or three times a day
• 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 tablets 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
• Discontinuation or Dosage Reduction of Lorazepam Tablets To reduce the risk of withdrawal reactions, use a gradual taper to discontinue lorazepam tablets or reduce the dosage
• If a patient develops withdrawal reactions, consider pausing the taper or increasing the dosage to the previous tapered dosage level
• Subsequently decrease the dosage more slowly (see and DRUG ABUSE AND DEPENDENCE: Dependence )

Clinical studies of lorazepam generally were not adequate to determine whether subjects aged 65 and over respond differently than younger subjects; however, the incidence of sedation and unsteadiness was observed to increase with age (see ). Age does not appear to have a significant effect on lorazepam kinetics (see ). …

• Advise the patient to read the FDA-approved patient labeling ( Error! Hyperlink reference not valid. )
• Risks from Concomitant Use with Opioids Advise both patients and caregivers about the risks of potentially fatal respiratory depression and sedation when lorazepam is used with opioids and not to use such drugs concomitantly unless supervised by a healthcare provider
• Advise patients not to drive or operate heavy machinery until the effects of concomitant use with the opioid have been determined (see and ). …

Lorazepam is contraindicated in patients with: • hypersensitivity to benzodiazepines or to any components of the formulation • acute narrow-angle glaucoma.

The concomitant use of benzodiazepines and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at GABA A sites and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid-related respiratory depression exists. Limit dosage and duration of concomitant use of benzodiazepines and opioids, and monitor patients closely for respiratory depression and sedation. …

Risks from Concomitant Use with Opioids Concomitant use of benzodiazepines, including lorazepam, and opioids may result in profound sedation, respiratory depression, coma, and death. Because of these risks, reserve concomitant prescribing of these drugs in patients for whom alternative treatment options are inadequate. Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioids alone. …

Most adverse reactions to benzodiazepines, including CNS effects and respiratory depression, are dose dependent, with more severe effects occurring with high doses. 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. …

Pregnancy Pregnancy Exposure Registry There is a pregnancy registry that monitors pregnancy outcomes in women exposed to psychiatric medications, including lorazepam, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychiatric Medications at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/pregnancyregistry/. …

Overdosage of benzodiazepines is characterized by central nervous system depression ranging from drowsiness to coma. In mild to moderate cases, symptoms can include drowsiness, confusion, dysarthria, lethargy, hypnotic state, diminished reflexes, ataxia, and hypotonia. Rarely, paradoxical or disinhibitory reactions (including agitation, irritability, impulsivity, violent behavior, confusion, restlessness, excitement, and talkativeness) may occur. In severe overdosage cases, patients may develop respiratory depression and coma. …

Controlled Substance Lorazepam tablets contains lorazepam, a Schedule IV controlled substance. Abuse Lorazepam is a benzodiazepine and a CNS depressant with a potential for abuse and addiction. Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects. Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a healthcare provider or for whom it was not prescribed. …

Tome assim que lembrar, a menos que esteja quase na hora da próxima dose. Nesse caso, pule a dose esquecida. Nunca tome duas doses de uma vez para compensar. Confira a bula, pois alguns medicamentos são diferentes.
