Preventive Medications are usually taken every day
and prevent a migraine from happening.
They reduce how often people get a migraine, how severe it is, and how long each attack lasts.
Abortive Medications are taken in the early phases of a migraine
as soon as the person feels symptoms coming on.
They work to reduce or stop migraine-associated pain and related symptoms after they start.
Rescue Medications
are usually taken if abortive medications fail to work or cannot be taken for some reason.
They don't stop a migraine from happening, but help reduce non-headache symptoms, like nausea, vomiting, and dizziness.
