New First-Line Recommendations and Practical Strategies for Clinical Practice

Migraine is one of the most common and disabling neurological disorders worldwide, affecting more than one billion people and ranking among the leading causes of years lived with disability. Despite its prevalence, migraine remains underdiagnosed and undertreated, particularly when it comes to preventive therapy. Recent advances in migraine science have transformed prevention strategies, prompting updated clinical recommendations that emphasize earlier, more effective intervention.

This continuing medical education (CME) update highlights new first-line preventive options and provides practical guidance for managing patients with frequent or disabling migraine.

When to Consider Preventive Migraine Therapy

Preventive treatment is recommended for patients who experience frequent migraine attacks or significant migraine-related disability. Current guidance suggests initiating prevention in patients who have:

• Four or more migraine days per month

• Two or more migraine days per month with substantial disability

• Poor response, intolerance, or contraindications to acute treatments

• Risk of medication-overuse headache

• Patient preference for reducing attack frequency and severity

The goal of preventive therapy is not complete elimination of migraine, but a meaningful reduction in attack frequency, intensity, duration, and reliance on acute medications.

Evolving Understanding of Migraine Pathophysiology

Advances in migraine research have clarified the role of calcitonin gene-related peptide (CGRP), central sensitization, and altered pain processing in migraine. This improved understanding has driven the development of targeted therapies that address migraine mechanisms more specifically than traditional preventives.

As a result, prevention is no longer limited to repurposed medications originally developed for hypertension, depression, or epilepsy.

New First-Line Preventive Treatment Options

CGRP-Targeted Therapies

CGRP monoclonal antibodies are now recognized as first-line options for migraine prevention in many patients. These therapies include both injectable and oral agents designed specifically for migraine prevention.

Key advantages include:

• Migraine-specific mechanism of action

• Rapid onset of benefit

• Favorable tolerability profile

• Minimal drug–drug interactions

CGRP inhibitors are particularly beneficial for patients who have failed or cannot tolerate traditional preventive medications.

Traditional Preventive Medications Still Matter

Established preventive agents remain appropriate first-line options for many patients, particularly when cost, comorbidities, or access to newer therapies are considerations. These include:

• Beta-blockers (e.g., propranolol, metoprolol)

• Antiseizure medications (e.g., topiramate, valproate)

• Antidepressants (e.g., amitriptyline, venlafaxine)

Selection should be individualized based on patient characteristics, comorbid conditions, and side-effect profiles.

OnabotulinumtoxinA for Chronic Migraine

For patients with chronic migraine (15 or more headache days per month), onabotulinumtoxinA remains an evidence-based preventive option. It is particularly useful in patients with medication overuse or those who have failed multiple oral preventives.

Practical Guidance for Clinicians

Start Low, Go Slow — but Don’t Wait Too Long

Titration remains important, especially with oral preventives. However, experts emphasize avoiding prolonged trials at subtherapeutic doses. A fair trial typically lasts 8–12 weeks at a therapeutic dose before assessing effectiveness.

---

Set Realistic Expectations

Patients should understand that:

• Improvement may be gradual

• A 50% reduction in migraine days is considered a successful response

• Preventive therapy works best when combined with lifestyle optimization

Clear communication improves adherence and satisfaction.

---

Address Comorbidities and Triggers

Effective migraine management requires a holistic approach. Clinicians should screen for and address:

• Sleep disorders

• Anxiety and depression

• Hormonal influences

• Stress and lifestyle factors

Nonpharmacologic strategies such as regular sleep, hydration, exercise, and stress management remain foundational.

---

Reducing Medication-Overuse Headache

Frequent use of acute migraine medications can worsen headache frequency and reduce preventive effectiveness. Preventive therapy plays a critical role in breaking this cycle by decreasing reliance on rescue medications.

Early initiation of prevention can help prevent progression from episodic to chronic migraine.

---

Individualizing Treatment Decisions

There is no single “best” preventive therapy for all patients. Updated recommendations emphasize shared decision-making that considers:

• Migraine frequency and severity

• Prior treatment response

• Comorbid medical conditions

• Patient preferences and lifestyle

• Insurance coverage and cost

This personalized approach improves long-term outcomes and adherence.

---

The Future of Migraine Prevention

The migraine prevention landscape continues to evolve, with ongoing research into new molecular targets, combination strategies, and biomarkers that may help predict treatment response. As understanding deepens, prevention is shifting from a trial-and-error process to a more targeted, patient-centered model.

---

Conclusion

Migraine prevention has entered a new era. Updated first-line recommendations now include migraine-specific therapies alongside traditional options, allowing clinicians to intervene earlier and more effectively. By recognizing candidates for prevention, selecting appropriate therapies, and partnering with patients, clinicians can significantly reduce migraine burden and improve quality of life.

Staying current with evolving migraine guidelines is essential—not only to reduce headache frequency, but to restore function, productivity, and well-being for patients living with this disabling neurological disease.
