Depression medication

Hi,

A friend of mine currently claims long term incapacity benefit after surgery.Things have got on top of her and she wants to go onto medication.I stand by this decision as I can see a definate change in her.

Anyways,I dont beleive prescriptions are free on IB,so could someone tell me...

a.if there is any financial help she'll get.
b.how much "typical" depression medication is

Even this is getting her down cos she doesnt have much left after bill paying etc,and doesnt think she'll be able to afford medication she needs.

Thanks.
