Mary Harney's success in cutting the trade price on 300 commonly used medicines by 40% will save the taxpayer around €90m and deserves to be commended.


It's true we paid well over the odds for too long for these drugs compared with other countries, but at the same time, the fact that officials drove the price down is a big plus.


But unfortunately, people without medical cards won't benefit as much as they should because now the chemists are going to rip us off instead of the drug companies.


Rather than pass on the savings, many are charging the old price and pocketing the profit.


There are no regulations which can force chemists to drive down prices because competition law won't allow it. They can charge what the market will allow. So consumers must vote with their feet.


The Irish Pharmaceutical Healthcare Association, the drug companies' trade body, has put the names and prices of the 300 medicines and their new prices on the website www.checkthelist.ie.


Knowing how much your pharmacy should charge is the first step in boycotting those who rip you off. The power is with you, not your chemist.
