According to the article those taking this medication lost an average of 4kg (8.8lb) over 40 months. 5-10% of their body weight.
At a cost of "about $220-290 (£155-225) per month". So about $8,800 - $11,600 (£6,200 - £9000) for the 40 months per person.
I lost 5kg (11lb) in 4 weeks by reducing bread, pasta and rice intake. About 5% of my body weight. Cost negative as I paid for less food.
Is N.I.C.E. likely to allow this medication on prescription?
