From the Guidelines

Ativan (lorazepam) should be dosed at 0.5-1 mg orally four times a day as required in primary care, with a maximum of 4 mg in 24 hours, according to the most recent guidelines. This dosing recommendation is based on the study published in the BMJ in 2020, which provides guidance on managing COVID-19 symptoms, including anxiety and agitation, in the community 1.

Key Considerations

  • The dose should be reduced to 0.25-0.5 mg in elderly or debilitated patients, with a maximum of 2 mg in 24 hours, to minimize the risk of adverse effects.
  • Oral tablets can be used sublingually, although this is considered an off-label use.
  • It is essential to monitor patients for potential side effects, including sedation, cognitive impairment, and respiratory depression, and to educate them about the risks of combining Ativan with other CNS depressants or alcohol.
  • Treatment duration should be limited to the shortest duration necessary to achieve the desired therapeutic effect, and discontinuation should involve gradual tapering to prevent withdrawal symptoms.

Special Populations

  • Elderly patients: reduce the dose to 0.25-0.5 mg, with a maximum of 2 mg in 24 hours.
  • Debilitated patients: reduce the dose to 0.25-0.5 mg, with a maximum of 2 mg in 24 hours. These recommendations prioritize minimizing morbidity, mortality, and optimizing quality of life for patients receiving Ativan in primary care settings, as supported by the most recent and highest-quality evidence available 1.

From the FDA Drug Label

DOSAGE AND ADMINISTRATION ... For optimal results, dose, frequency of administration, and duration of therapy should be individualized according to patient response. The usual range is 2 mg/day to 6 mg/day given in divided doses, the largest dose being taken before bedtime, but the daily dosage may vary from 1 mg/day to 10 mg/day For anxiety, most patients require an initial dose of 2 mg/day to 3 mg/day given twice daily or three times daily. For insomnia due to anxiety or transient situational stress, a single daily dose of 2 mg to 4 mg may be given, usually at bedtime. For elderly or debilitated patients, an initial dosage of 1 mg/day to 2 mg/day in divided doses is recommended, to be adjusted as needed and tolerated

The recommended Ativan (lorazepam) dose for primary care is:

  • 2 mg/day to 6 mg/day given in divided doses for optimal results
  • 2 mg/day to 3 mg/day given twice daily or three times daily for anxiety
  • 2 mg to 4 mg given at bedtime for insomnia due to anxiety or transient situational stress
  • 1 mg/day to 2 mg/day in divided doses for elderly or debilitated patients 2

From the Research

Ativan Dose for Primary Care

There is no specific information provided in the given studies about the dose of Ativan for primary care. However, the following points can be noted:

  • Ativan, also known as lorazepam, is a benzodiazepine used to treat anxiety disorders 3.
  • Benzodiazepines, including Ativan, are effective in treating generalized anxiety disorder (GAD), but their use is often limited due to the risk of dependence and withdrawal symptoms 3, 4.
  • The studies provided do not mention the specific dose of Ativan for primary care, but they discuss the efficacy of benzodiazepines in treating GAD 5, 4.
  • Other treatment options for GAD, such as selective serotonin reuptake inhibitors (SSRIs) and cognitive behavior therapy, are also effective and may be considered as alternatives to benzodiazepines 6, 7.

Treatment Options for GAD

Some key points about treatment options for GAD include:

  • Cognitive behavior therapy is an effective treatment for GAD and may have more durable effects than pharmacologic agents 6.
  • SSRIs and SNRIs are commonly prescribed medications for GAD, but benzodiazepines may be more effective in the short term 4.
  • Non-drug therapies, such as interpersonal and cognitive therapies, can also be helpful in treating patients with GAD 5.
  • Providers may use a variety of interventions, including psychoeducation, relaxation training, and supportive therapy, to treat anxiety in primary care settings 7.
