WHAT YOU NEED TO KNOW ABOUT MIGRAINE (Part Two)

DRUG THERAPY OF MIGRAINE

The drug therapy of migraine depends on the severity and frequency of attacks, and the response of individual patients to these drugs. Based on severity, migraine can be grouped into:

Mild migraine whereby migraine attacks are less than one per month and headaches are throbbing but tolerable, lasts up to 8hours and do not incapacitate the individual.

Moderate migraine where the throbbing headache is more intense, lasts for 6- 24hours, nausea, vomiting and other symptoms are more prominent and the patient is functionally impaired. Attacks are one or more per month.

Severe migraine where patients suffer 2-3 or more attacks per month and the throbbing headache usually lasts 12-48hours, usually accompanied by symptoms and patient is greatly incapacitated during the attack.

The strategy mostly adopted in the drug therapy of migraine can be summarized in the table below:
