Aspirin 'major bleed' warning for over-75s Aspirin 'major bleed' warning for over-75s
(about 9 hours later)
People over 75 taking daily aspirin after a stroke or heart attack are at higher risk of major - and sometimes fatal - stomach bleeds than previously thought, research in the Lancet shows.People over 75 taking daily aspirin after a stroke or heart attack are at higher risk of major - and sometimes fatal - stomach bleeds than previously thought, research in the Lancet shows.
Scientists say that, to reduce these risks, older people should also take stomach-protecting PPI pills.Scientists say that, to reduce these risks, older people should also take stomach-protecting PPI pills.

Doctors generally prescribe daily aspirin for life after a person has a stroke or heart attack to help prevent more attacks. Doctors in the UK generally prescribe daily aspirin (75mg) for life after a person has a stroke or heart attack to help prevent more attacks.
But researchers have known for some time that aspirin can increase the risk of stomach bleeds.But researchers have known for some time that aspirin can increase the risk of stomach bleeds.
Until now, most research involved people under 75, showing that the risk of serious bleeds was low in this group.Until now, most research involved people under 75, showing that the risk of serious bleeds was low in this group.
But with around half the people on lifelong aspirin in the UK now over 75, researchers at Oxford University decided to find out whether the benefits still outweigh the risks in this group.But with around half the people on lifelong aspirin in the UK now over 75, researchers at Oxford University decided to find out whether the benefits still outweigh the risks in this group.
Their study followed 3,166 patients who had previously had a stroke or heart attack and were prescribed aspirin or similar blood-thinning drugs.Their study followed 3,166 patients who had previously had a stroke or heart attack and were prescribed aspirin or similar blood-thinning drugs.
They found that, for patients aged under 65, the annual rate of disabling or fatal bleeds was less than 0.5% (around one person in every 200 people taking the medication).They found that, for patients aged under 65, the annual rate of disabling or fatal bleeds was less than 0.5% (around one person in every 200 people taking the medication).
Meanwhile, for people aged 75 to 84, this rose to three people having major bleeds in every 200.Meanwhile, for people aged 75 to 84, this rose to three people having major bleeds in every 200.

Lead researcher Prof Peter Rothwell said: "Our new study gives us a much clearer understanding of the size of the increased risk and the severity and consequences of bleeds in over-75s.Lead researcher Prof Peter Rothwell said: "Our new study gives us a much clearer understanding of the size of the increased risk and the severity and consequences of bleeds in over-75s.
"Our findings raise questions about the balance of risk and benefit of long-term daily aspirin use in people aged 75 or over if a PPI drug is not co-prescribed.""Our findings raise questions about the balance of risk and benefit of long-term daily aspirin use in people aged 75 or over if a PPI drug is not co-prescribed."
Dr Tim Chico, heart specialist at the University of Sheffield, described the work as a well-conducted study.Dr Tim Chico, heart specialist at the University of Sheffield, described the work as a well-conducted study.
He said: "Although bleeding is a well-recognised side-effect of aspirin, this drug is still seen by many people as harmless, perhaps because of how easily it can be bought over the counter."He said: "Although bleeding is a well-recognised side-effect of aspirin, this drug is still seen by many people as harmless, perhaps because of how easily it can be bought over the counter."
Meanwhile, GP leader Prof Helen Stokes-Lampard, said: "The study does reassure us that, in most cases, aspirin is still the most appropriate course of treatment for patients, but highlights the importance of managing its use carefully and effectively and that some patients may require additional medication to protect them."Meanwhile, GP leader Prof Helen Stokes-Lampard, said: "The study does reassure us that, in most cases, aspirin is still the most appropriate course of treatment for patients, but highlights the importance of managing its use carefully and effectively and that some patients may require additional medication to protect them."

Current guidelines in the UK recommend people at "high risk" are given a PPI (proton pump inhibitor) drug which protects the stomach, along with aspirin therapy.Current guidelines in the UK recommend people at "high risk" are given a PPI (proton pump inhibitor) drug which protects the stomach, along with aspirin therapy.

Why shouldn't aspirin be stopped suddenly?Why shouldn't aspirin be stopped suddenly?
Stopping aspirin suddenly has been shown to have a rebound effect - increasing the chance of heart attack, TIA and stroke for weeks after the pill is stopped.Stopping aspirin suddenly has been shown to have a rebound effect - increasing the chance of heart attack, TIA and stroke for weeks after the pill is stopped.
Anyone who is concerned must discuss it with their doctor. If stopping is advised, doctors will discuss cutting down pills gradually.Anyone who is concerned must discuss it with their doctor. If stopping is advised, doctors will discuss cutting down pills gradually.

Do stomach-protecting PPI drugs carry any risks?Do stomach-protecting PPI drugs carry any risks?
All drugs have risks and benefits and the decision to take them must be made after weighing these up for the individual. When it comes to PPIs the side-effects can include flatulence, bloating and sometimes stomach infections.All drugs have risks and benefits and the decision to take them must be made after weighing these up for the individual.
