Pharmacists in Ireland are now hoping that a new public education campaign will help people feel better faster.
Launched yesterday by the Irish Pharmaceutical Healthcare Association (IPHA) and Irish Pharmaceutical Union (IPU), the campaign also focuses on when a trip to a GP is necessary.
IPHA president John McLoughlin said changing lifestyles and the hectic pace of life in Ireland might be to blame for the frequency of many minor ailments.
Michael Guckian, president of IPU, said there were many medicines available without prescription that were extremely effective in treating minor ailments.
The aim of the new campaign, he said, was to help people self-treat minor ailments effectively, use non-prescription medicines correctly and to know when to seek advice from their pharmacist or GP.
Mr McLoughlin said thousands of GP visits were made for ailments that could be treated with non-prescription medicine recommended by a pharmacist.
“With so many people leading time-poor lifestyles, being able to self-treat minor ailments effectively and safely can have significant time-saving benefits,” he said.
Both the IPHA and IPU are also stressing the importance of reading medicine labels carefully and of checking with a pharmacist if people have questions.
“This might sound like obvious advice but research consistently shows that levels of compliance in relation to medication are as low as 50%,” said Mr McLoughlin.
The month-long campaign includes radio broadcasts and a website (www.feelbetter.ie). Information packs and fridge magnets are available in pharmacies.
