10 trials reviewed, only 1 useful. Patients <18 years oldSystemic review on randomised and controlled trials.Reduction of symptoms after 1 hourIV Prochlorperazine was more effective than IV Ketorolac in reduction of symptoms 1 hour after treatment.Complete follow up was not obtained on 6 children. No placebo was used therefore unable to comment on drug affect alone.

Reduction in severity75% at 1 hour, 95% at 3 hours
Failure1 patient failed to respond to Prochlorperazine

Clinical Bottom Line

Prochlorperazine belongs to a class of drugs called phenothiazines. Prochlorperazine is normally given to patients who experience nausea and vomiting. There were no studies confirming whether this drug was beneficial for treating migraine in patients with/without nausea and vomiting. However, the studies did report that over 50% of patients became pain free or improved 1 hour after treatment with Prochlorperazine. Side effects of Prochlorperazine were mild and only a few patients experienced side effects. Therefore, in conclusion Prochlorperazine is useful in treating/ decreasing the pain in migraine.
