Migraine management is a stepwise approach tailored to the severity and frequency of headache episodes, as well as the patient's response to treatment. The goal is to reduce the frequency, severity, and duration of migraine attacks and improve the patient's quality of life. Treatment can be divided into acute (abortive) and preventive (prophylactic) strategies.
Acute Treatment:
The aim of acute treatment is to stop or reduce the severity of a migraine attack once it has started.
First-line options for mild to moderate migraine attacks include:
NSAIDs (Nonsteroidal Anti-Inflammatory Drugs): Ibuprofen, naproxen, and aspirin are effective in reducing migraine pain and associated symptoms.
Acetaminophen (Paracetamol): Can be used alone or in combination with caffeine or an NSAID.
For moderate to severe migraines, or if NSAIDs and acetaminophen are ineffective, the first-line options are:
Triptans: Sumatriptan, rizatriptan, naratriptan, and others. Triptans are serotonin receptor agonists that reduce inflammation and constrict blood vessels.
Ergots: Ergotamine and dihydroergotamine (DHE), which are less commonly used due to their side effects but can be effective for some patients.
Side Effects of Ergot
For nausea and vomiting, adjunctive treatments include:
Anti-nausea medications: Metoclopramide, prochlorperazine, or ondansetron.
Preventive Treatment:
Preventive treatment is considered if migraines are frequent, typically more than four times a month, or if acute treatments are ineffective.
First-line options for preventive treatment include:
Beta-blockers: Propranolol and metoprolol have been shown to reduce the frequency and severity of attacks.
Anticonvulsants: Topiramate and valproate are effective for migraine prevention.
Calcium channel blockers: Verapamil is used to prevent migraines in some patients.
Antidepressants: Amitriptyline, a tricyclic antidepressant, is often used for migraine prevention, especially if the patient also has depression or insomnia.
Newer options include:
CGRP (Calcitonin Gene-Related Peptide) antagonists: Erenumab, fremanezumab, and galcanezumab are monoclonal antibodies designed to prevent migraines by targeting the CGRP pathway, which is involved in the development of migraine pain.
Lifestyle modifications and non-pharmacological treatments should also be part of the management plan. This includes regular exercise, maintaining a healthy diet, ensuring adequate hydration, stress management techniques, and avoiding known migraine triggers.
