Xanax (alprazolam) typically starts working within about 30 to 60 minutes after ingestion. Most people begin to feel its calming and sedative effects around 1 hour after taking it. The drug reaches peak concentration in the bloodstream within 1 to 2 hours. The calming effects generally last for about 4 to 6 hours, though this can vary depending on metabolism, liver function, dosage, and individual health factors. Extended-release versions, like Xanax XR, take longer to peak but have a more sustained effect. In summary:
- Onset of effects: 30 to 60 minutes
- Peak effects: 1 to 2 hours
- Duration of calming effects: 4 to 6 hours
- Full clearance from the body: 2 to 6 days depending on individual metabolism
It is important to follow healthcare provider dosing instructions carefully to use Xanax safely and effectively.
