From the Guidelines
Benzodiazepines are the most effective quick-acting medications for rapid relief of anxiety symptoms, with options like lorazepam, alprazolam, diazepam, and clonazepam being commonly prescribed. These medications are preferred for short-term use due to their rapid onset of action, typically within 15-60 minutes, by enhancing the effect of the neurotransmitter GABA in the brain, which reduces neuronal excitability and produces a calming effect 1. When selecting a benzodiazepine, considerations should include the patient's age, side-effect profile, potential interactions, and personal preference, as outlined in recent guidelines for managing anxiety and depression 1. Some key points to consider when prescribing benzodiazepines for anxiety relief include:
- Starting doses, such as 0.5-1mg for lorazepam, 0.25-0.5mg for alprazolam, 2-5mg for diazepam, or 0.5mg for clonazepam, which can be adjusted based on patient response and tolerance.
- Monitoring for adherence, side effects, and adverse events, given the potential risks of dependence, tolerance, and withdrawal with regular use beyond 2-4 weeks.
- Informing patients about potential side effects, including drowsiness, dizziness, and impaired coordination, and advising them to avoid driving or operating machinery until they are familiar with how the medication affects them. Given the potential for long-term dependence and other adverse effects, benzodiazepines are generally recommended for short-term use, with non-benzodiazepine options like SSRIs or therapy preferred for ongoing anxiety management, as suggested by recent clinical guidelines 1.

From the Research
Quick-Acting Medications for Anxiety Relief
- Benzodiazepines are a class of medications that can provide rapid relief for anxiety symptoms, with some studies showing effectiveness in as little as 10 minutes 3.
- Short-acting benzodiazepines such as lorazepam and oxazepam are often preferred for episodic anxiety, as they can provide quick relief without the risk of dependence associated with long-term use 4.
- Lorazepam has been shown to be highly effective in relieving anxiety in clinical trials, with significant improvements in symptoms compared to placebo 5, 3.
- Other benzodiazepines, such as alprazolam, have also been shown to be effective in treating panic disorder, although they may have similar efficacy to lorazepam 6.
Comparison to Other Medications
- Selective serotonin reuptake inhibitors (SSRIs) are also commonly used to treat anxiety disorders, but they can take several weeks to have a therapeutic effect, whereas benzodiazepines have a rapid onset of action 7.
- While SSRIs are associated with a delay in onset of therapeutic effect, benzodiazepines can cause tolerance and dependence, highlighting the need for careful consideration of the risks and benefits of each medication 7.
