How long for 4mg Ativan to get out .ofthe system Was only taken for 1 day?

Ativan (lorazepam) has a half-life of approximately 10 to 20 hours, meaning it takes that long for half of the drug to be eliminated from the body. For a single dose of 4 mg, it may take about 2 to 3 days for the drug to be mostly cleared from your system. However, individual factors like metabolism, age, and overall health can affect this timeframe. If you have specific concerns, it's best to consult a healthcare professional.
