Doctors still routinely give patients a blood thinner such as warfarin
and heparin for six months to treat deep vein thrombosis (DVT) or
pulmonary embolism – and they could be putting the patient’s life at
risk by doing so.
Since 1992, recommended treatment time for anticoagulants, or blood
thinners, has been set at three months’ maximum, and yet doctors still
regularly prescribe them for a six-month period.
The patient gets no benefit from the extended therapy – in fact, he or
she is more likely to die, or suffer a recurrence or hemorrhage, than
if he stopped the drug therapy after the recommended three months.
The difference has been underlined in yet another trial, which tested
the two treatment periods on a group of 749 DVT or pulmonary embolism
patients. After a year, 19 of those who had the six months’ treatment
had died, compared with 14 in the three-month trial group, while 35
suffered some serious reaction from the treatment – usually a major
hemorrhage – after the six months’ therapy, as against 31 in the three
months’ trial.
Not that anticoagulants are especially safe even when given over a
short time. The UK’s National Patient Safety Agency has revealed that,
last year, 120 people in the UK died and a further 480 suffered
‘serious harm’ after being given warfarin. These deaths and reactions
were mainly due to doctor error and a failure to monitor the patient
after prescribing a powerful dose of the drug.
