The safety of acupuncture for migraine prevention during pregnancy.

Relief from migraine attacks may be obtained through non-pharmacological therapy during pregnancy when most drugs are contraindicated. There is accumulating evidence for the efficacy and safety of acupuncture for migraine in the general population but very little to no data on acupuncture during pregnancy. With this retrospective study, we wanted to determine whether an association exists between acupuncture treatment and preterm delivery and side effects of therapy.
