If i'm prescribed ativan (lorazepam) 0.5 bid prn for post partum anxiety how long can i take it before it's addictive? it's helpful but i'm concerned.

Post partum anxiety: Medications such as Ativan (lorazepam) are addictive in the sense that they are quickly adapted to, and to achieve the same effect, higher doses are required. The general post-partum anxiety is caused in part by sudden drops in estrogen, but unless you are nursing, your regular cycle should resume within 6-8 weeks after delivery. You should consult your healthcare provider to evaluate the need to continue.
