The frequency of migraine headaches described as crushing, vicelike or eye-popping can be reduced by Botulinum shots used for cosmetics.

Migraine headaches affect approximately 28 million Americans, known to cause pain that is often debilitating. Researchers conducting clinical trials on botulinum toxin type A to treat facial

lines recognized a correlation between the shots and the alleviation of migraine symptoms.

Christine C. Kim, then of SkinCare Physicians, Chestnut Hill, Massachusetts, and now a private practitioner in Encino, California, and colleagues studied patients (average age 50.9 years) who

had already received or were planning to receive botulinum injections for cosmetic purposes but also reported having migraines.

Three months after treatment, more than two thirds of the patients had responded to the treatment with a reduction in migraine pain, including those who had imploding or ocular headaches and

those who had exploding headaches.

A JAMA release said that a third of the patients who did not respond had exploding headaches.

February issue of Archives of Dermatology has published these findings in the February issue of Archives of Dermatology. (With Input from Agencies)
