Many people rely on
painkillers for various ailments and injuries. Common problems such as
headaches, back aches and temperatures can be eased by taking pills like paracetamol and ibuprofen.
While these are safe to use in accordance with the package instructions, research has shown there are risks to taking them regularly.
It had been previously assumed that paracetamol was a completely safe drug to use in patients with high
blood pressure until fairly recently.
However, a
2022 study found that long-term use of paracetamol could increase the risk of
heart disease and
stroke among people with hypertension.
The effect on blood pressure is similar to that of non-steroidal anti-inflammatories (NSAIDs), such as ibuprofen, researchers have said.
As part of the study conducted by a team at the University of Edinburgh, 110 patients with a history of high blood pressure were prescribed either one gram of paracetamol four times a day or a matched placebo for two weeks.
Four grams of paracetamol a day is a routinely prescribed dose in patients with chronic pain.
All patients received both treatments, with the order randomised and blinded.
Those prescribed paracetamol saw a significant increase in their blood pressure, compared with those taking the placebo.
