Painkillers 'can cause' headaches
Common painkillers could be causing people to have headaches, Britain's health watchdog has warned.
People who regularly take medicines such as aspirin, paracetamol and triptans could be causing themselves more pain than relief, the National Institute for Health and Clinical Excellence (Nice) said.
Medication “overuse” could contribute to headaches for people who have been taking such medicines for up to half of the days in a month over three months, a spokesman said. The watchdog estimated that one in 50 people who experience headaches suffer because of medication overuse.
It said common over-the-counter treatments are effective for easing the pain of occasional headaches but using them for tension-type headaches or migraine can reduce their effectiveness and cause further pain.
People who suffer from such headaches could be in a vicious cycle where their headaches are getting worse because of medication overuse and to alleviate symptoms they take more drugs.
Issuing new guidance to healthcare professionals, the institute said different headaches require different treatments, so a correct diagnosis is vital.
More than 10 million people in the United Kingdom experience regular or frequent headaches, according to Nice. They account for one in 25 GP consultations.
Martin Underwood, a GP and professor of primary care research at Warwick Medical School who chaired the guideline’s development, said: “We have effective treatments for common headache types.
“However, taking these medicines for more than 10 or 15 days a month can cause medication overuse headache, which is a disabling and preventable disorder.
“Patients with frequent tension-type headaches or migraines can get themselves into a vicious cycle, where their headaches are getting increasingly worse, so they take more medication which makes their pain even worse as they take more medication," he said.
“Explaining to patients that they should abruptly stop their medication, knowing that their headache will get much worse for several weeks before it will improve, is not an easy consultation,” Dr Underwood added.
