From the Guidelines
The typical starting dose of alprazolam for adults with anxiety is 0.25 to 0.5 mg orally 3 times daily, beginning on the night before treatment. This dose is recommended to minimize side effects while allowing the body to adjust to the medication 1. The dose may be gradually increased if needed, with most patients requiring between 1 to 4 mg total daily dose divided into multiple administrations. It's essential to note that elderly patients, patients with debilitating disease, and those with advanced liver disease should start with a lower dose of 0.25 mg orally 2 or 3 times daily for treatment of anxiety 1.
Some key points to consider when prescribing alprazolam include:
- The dose should be gradually reduced when decreasing or discontinuing alprazolam therapy to avoid withdrawal symptoms 1
- Alprazolam can cause physical dependence, so it's crucial to take it exactly as prescribed 1
- Side effects may include drowsiness, dizziness, and impaired coordination, so patients should avoid driving or operating machinery until they know how the medication affects them 1
- Alprazolam should be used as part of a comprehensive treatment plan that may include therapy and lifestyle modifications 1
It's worth noting that the evidence from 1 is more recent and of high quality, providing a clear guideline for the starting dose of alprazolam for adults with anxiety. While 1 also provides similar information, 1 is preferred due to its recency and prestige of the journal.

From the Research
Typical Starting Dose of Alprazolam
The typical starting dose of alprazolam for adults with anxiety is not explicitly stated in the provided studies. However, the following information can be gathered:
- The average dose of alprazolam used in the treatment of panic disorder was 1.36 ± 0.70 mg/day 3.
- In a study of alprazolam treatment for panic disorders, the mean dose was 2.2 mg/day 4.
- There is no specific information on the starting dose, but the studies suggest that the dose of alprazolam can vary depending on the individual and the condition being treated.
Key Points to Consider
- Alprazolam is approved for use in panic disorder and generalized anxiety disorder 5.
- The use of alprazolam should be carefully considered due to its potential for abuse and dependence 5.
- Alternate pharmacological and non-pharmacological strategies for use in anxiety and insomnia are available, which might be safer than alprazolam 5.
Dosing Information
- The dose of alprazolam can range from 1.33 ± 0.64 mg/day to 2.2 mg/day, depending on the study and the condition being treated 3, 4.
- The extended-release formulation of alprazolam allows for once-daily dosing, which can help reduce fluctuation in therapeutic effect and curb the clock-watching phenomenon between doses 6.
