[73] For the period after the first three years up to the end of the preclusion period, 22 March 2015, the additional cost of Efexor needs to be taken into account. As I have already said, the total cost per week comes to $42.06 including Efexor. Again, allowing for the PBS cap, the plaintiff's future annual cost will be $1,281.30 plus $5.40 per script thereafter. The average cost per script was calculated to be $23.57 ($2,187.12/92.79). The average number of scripts per year above the safety net was said, therefore, to be 38.43 ($905.82/$23.57). Allowing $5.40 for each of these, the additional cost (after the safety net is triggered) would be $207.52. The total annual cost to the plaintiff will therefore be $1,281.30 plus $207.52, giving $1,488.82 per annum. This is a weekly expense of $28.63. This figure discounted on the 5 per cent tables for 4.86 years (the difference between the preclusion period and 3 years), deferred for three years, comes to $5,698.36.
