Does Ativan cause weight gain or loss?
Weight changes on medication are one of the most common reasons people consider switching or stopping.

Documented weight effects of Ativan
Whether Ativan causes weight gain, loss or no meaningful change depends on Lorazepam and how it acts. Some medications in Anti-anxiety Medications affect appetite directly; others alter fluid balance, metabolic rate, or sleep — all of which can shift weight. The prescribing information lists weight effects observed in clinical trials.
Practical management
Modest weight changes (±1–3 kg) over the first months on Ativan at 0.5mg, 1mg, 2mg are common and often resolve without intervention. Larger or distressing changes deserve a discussion with the prescriber. According to general clinical guidance, the right response is not always to stop Ativan — diet, activity, sleep and addressing the underlying condition all matter.
