First, it depends on what medication you are using. Some meds state you can repeat the dose in 4 hours, others require 6-8 hours between dosing. You do not include enough information in this post for anyone to answer this properly. Most all migraine medications can be repeated as needed until the migraine is gone but there should be instructions on the label of the medication, telling you how soon you can repeat a dose.
