Can cold packs ease migraine pain?

Though cooling products like Thera-Med Headache Band and WellPatch and Migraine Be Koool pads may offer some headache relief, don't expect to throw out medication altogether.

The word " headache" doesn't really do justice to a migraine. Migraines don't just ache; they take over. Once the pain starts, it's hard to think about anything else.

Millions of migraineurs tackle their pain with prescription or over-the-counter drugs. But there are other options. For about $4, you can buy a pack of four WellPatch Migraine pads from Mentholatum. Users are instructed to stick a pad on their forehead as soon as pain starts. The pad is filled with a watery gel that starts evaporating when the package is opened. The evaporation cools the skin beneath the pad, a sensation that's enhanced by a subtle scent of menthol. According to the package, the cooling lasts up to eight hours.

Migraine Be Koool pads, a very similar product from Kobayashi Healthcare, also sell for about $1 each. Like the WellPatch Migraine pads, Migraine BeKoool pads stick directly to the forehead and cool the skin through evaporation. And, like the WellPatch, they have a little menthol for extra cooling.

The Thera-Med Headache Band from Carex takes a colder approach to migraine relief. Unlike the WellPatch or Be Koool pads, it chills out in the freezer or refrigerator when not in use. The band, which is held in place with Velcro straps, contains a "micro-gel" that freezes without hardening. One side of the band is covered in fabric for a more gentle cool-down, kind of like wrapping a towel around an ice pack. People who want extra cold can use the side without the fabric. Expect to pay less than $10 for each band, which can be reused indefinitely.

The claims: The WellPatch website says that the pad "cools and soothes the discomfort associated with migraine." Todd Cantrell, director of marketing at Mentholatum, clarifies that the pads don't really treat the migraine itself but can make the whole experience a little more bearable.

The website for Migraine Be Koool says that "nothing provides more immediate and soothing relief to migraine headaches than Migraine Be Koool." Kobayashi Healthcare didn't respond to requests for comment.

The Thera-Med website says that the band "helps relieve migraine, tension and sinus headaches." It also says that "researchers have found that cold treatment is shown to be effective in 50-60% of headache sufferers." Fred Thiemann, a product manager for Carex, notes that "many people spend lots of money on drugs for headaches," adding that the pad could "solve their problem" at a fraction of the price.

The bottom line: Cold isn't a miracle cure for migraines, but it can definitely bring some relief, says Dr. Frederick Freitag, co-director of the Diamond Headache Clinic in Chicago. In fact, he co-authored a study published nearly 25 years ago showing that frozen gel packs helped about 70% of headache patients who tried it. About half said that the relief was immediate.

Freitag says that commercial headache pads could be worth a try. "I'm sure they help some people," he says, adding that the relief might be at least partly psychological. He's not convinced that the WellPatch or Be Koool pads could get cold enough to "really make a difference." Still, the mere suggestion of cold could be soothing for some people, he says.

Cold packs like the Thera-Med band could potentially bring even more relief, Frietag says, but he points out that there's an even cheaper, easier option: "I tell patients to pick up a bag of frozen peas and wrap it in a towel." They can reuse the bag as often as they like, he says, and they can place it where it hurts (usually one of the temples) instead of the forehead.

"Cooling has been used [for headaches] since the 19th century," says Dr. Roland Brilla, a clinical assistant professor of neurology at the University of Wisconsin School of Medicine and Public Health in Madison and a member of the American Headache Society. Though many patients say cold helps a bit, he cautions that "it doesn't seem to be extremely effective."

There's no downside to trying a headache pad, Brilla says. But, he adds, if patients think they can trade in their medications for a little chilly headwear, they're bound to be disappointed.
