What Not to Do for Migraines
THURSDAY, Nov. 21, 2013 (HealthDay News) — Prescription pain medications should not be the first treatment for migraines. And doctors shouldn’t routinely order brain scans for patients with these debilitating headaches, according to new guidelines.
Taking a stand on common but often unnecessary or potentially risky tests and treatments for migraine, the American Headache Society published new recommendations in the November-December issue of the journal Headache.
“Our aim is to encourage doctors and patients to think carefully about medical care that can be harmful or unnecessary,” said Dr. Elizabeth Loder, president of the American Headache Society. “We didn’t approach this with cost uppermost in mind. The goal is to help address the problems of low-value care.”
Opioid painkillers, such as OxyContin and Vicodin, and the barbiturate butalbital pose serious long-term risks, the society said.
“The effectiveness of opioids is not the question,” explained Loder, chief of the division of headache and pain in the neurology department at Brigham and Women’s Hospital in Boston. “The problem is that even if they are effective in a single attack, for many people migraine is a chronic disorder that they will have for many decades.”
The risk of dependency associated with these drugs is evidenced by the growing epidemic of prescription painkiller abuse in the United States. Nearly three out of four prescription drug overdoses are caused by opioid painkillers, according to the U.S. Centers for Disease Control and Prevention.
“This ends up being a second problem patients have,” Loder noted.
Using too much of these pain medications can also lead to a condition called medication overuse headache, said another expert.
“There is a lot of research that opioids actually increase the sensitivity to pain in the head,” said Dr. Rebecca Erwin Wells, assistant professor of neurology at Wake Forest Baptist Medical Center in Winston-Salem, N.C. Medication overuse headaches are difficult to treat, Wells added.
In addition, the guidelines indicate that brain scan studies should not be performed on patients with stable headaches that meet criteria for migraine. And CT scans should not be used in a non-emergency situation as a diagnostic tool for headache patients when MRI is available.
“MRI can diagnose more conditions that may cause headache that CT scans can miss,” Loder explained.
Also, unlike CT scans, MRIs use powerful magnets and do not expose patients to radiation. “MRI is better value and safer,” Loder concluded.
The headache specialists also said that surgery targeting migraine trigger points is still experimental and not recommended outside of a clinical trial.
“We lack sufficient evidence to say the benefits of surgery outweigh the potential harms or that it is even helpful,” Loder cautioned. Before new drugs can be approved for use, they must go through rigorous testing that meets a certain standard, she noted, “and the standard for surgical interventions that are irreversible should not be lower.”
