CGRP Inhibitors for Migraine:
What They Are and How They Work

June 1, 2026 • The Headache Lab • 8 min read

Quick Answer

CGRP inhibitors are a newer class of medications specifically designed to target the protein responsible for triggering migraine attacks, offering real relief for patients who haven’t responded to older treatments. Available as monthly injections or oral tablets, they can reduce migraine days by 50% or more. They are one of the most significant advances in migraine medicine in decades.

A New Treatment Option

If you’ve been dealing with migraines for years, you’ve probably tried a lot of things. Maybe some helped a little. Maybe nothing really did. That’s a frustrating place to be, and it’s exactly where a newer class of medications called CGRP inhibitors tends to come up in conversation.

These treatments have genuinely shifted how a lot of providers approach migraine prevention, especially for patients who’ve already burned through the older options without much luck. At The Headache Lab, we’ve seen firsthand how much of a difference they can make for people in Westmont and across Chicagoland who thought they’d run out of roads to try.

So what’s actually going on with these medications? Here’s a straightforward breakdown.

How CGRP Inhibitors Work

There are two main ways these medications block CGRP’s activity:
Monoclonal antibodies latch onto either the CGRP molecule itself or the receptor it tries to bind to, essentially cutting off the signal before it can trigger an attack. Because antibodies stay in the body a long time, a single injection can provide coverage for anywhere from four to twelve weeks.

Gepants are oral medications that block the CGRP receptor too, but their smaller molecular size means they absorb quickly. That makes them useful for stopping a migraine that’s already ramping up, not just preventing future ones.

Whats Available Right Now

On the preventive side, four monoclonal antibodies are currently approved in the U.S.:

  • Erenumab (Aimovig): monthly injection, targets the CGRP receptor
  • Fremanezumab (Ajovy): monthly or quarterly injection, targets CGRP itself
  • Galcanezumab (Emgality): monthly injection, targets CGRP itself
  • Eptinezumab (Vyepti): quarterly IV infusion, targets CGRP itself

Gepants give you more flexibility, since several work for both acute and preventive use:

  • Ubrogepant (Ubrelvy): acute treatment
  • Rimegepant (Nurtec ODT): both acute and preventive
  • Atogepant (Qulipta): preventive

For patients who’ve had bad experiences with triptans, or just can’t use them, gepants are often worth a serious look.

Migraine With Aura: Why You May See Zigzag Lines Before a Headache

May 21, 2026 • The Headache Lab • 7 min read

What’s Actually Happening During an Aura?

There is a clear neurological reason that an aura occurs.

Before a migraine starts, a wave of electrical activity moves across the brain’s surface, followed by a period when activity slows down. This process, called cortical spreading depression, temporarily interferes with normal brain signals and causes the sensory symptoms of aura.

Aura usually lasts between 5 and 60 minutes and goes away on its own. After that, the headache phase begins. About 25 to 30 percent of people with migraine experience aura at some point.

What Does Aura
Feel Like?

Aura can look different for each person, but there are some common patterns to know.

Visual aura is the most common type. People often describe:

  • Blinking or shimmering at the edge of their vision
  • Zigzag or arc-shaped patterns (sometimes called a “fortification spectrum”)
  • A blind spot or area of blurred vision
  • Tunnel vision or partial loss of sight in one eye

Aura can also cause symptoms besides vision changes, such as:

  • Sensory changes: tingling or numbness that often starts in the hand and moves up the arm toward the face
  • Language difficulty: trouble finding words or speaking clearly
  • Motor weakness: heaviness or weakness on one side of the body (less common, and worth discussing with a provider)

How Is It Diagnosed?

There is a clear neurological reason that an aura occurs.

Before a migraine starts, a wave of electrical activity moves across the brain’s surface, followed by a period when activity slows down. This process, called cortical spreading depression, temporarily interferes with normal brain signals and causes the sensory symptoms of aura.

Migraine With Aura vs. Without: How to Tell the Difference

Both types involve the same main migraine symptoms: moderate to severe head pain, sensitivity to light and sound, and often nausea. The difference is whether neurological symptoms come before the headache.

Some people have aura without any headache, which is called a silent migraine. The visual or sensory symptoms happen, but no headache follows. This can feel unsettling the first time, especially if you don’t know what it is.

What Sets Off a
Migraine With Aura?

Triggers for migraine with aura are often the same as for other migraines, though they can vary from person to person. The most common ones include:

  • Sleep disruption: both too little and too much
  • Hormone changes: especially around menstruation, perimenopause, or changes in contraception
  • Stress: and the let-down period after stress
  • Skipping meals or dehydration
  • Sensory overload: bright lights, strong smells, loud environments
  • Weather changes: shifts in barometric pressure

Treatments That
Really Help

Managing migraine with aura usually involves having a plan for when an episode starts and a long-term strategy to reduce how often they occur.

When a Migraine
Is Coming On

Triggers for migraine with aura are often the same as for other migraines, though they can vary from person to person. The most common ones include:

  • CGRP inhibitors taken at the onset of aura or other symptoms are very effective in preventing progression to the migraine phase.
  • Triptans are another acute option. They work best when taken early in the headache phase, not during the aura.
  • NSAIDs and combination pain relievers can help with milder episodes.
  • Anti-nausea medicines are often used along with pain relief.

Preventing Episodes From Happening

For people who have frequent or severe migraines, preventive therapy may be helpful:

  • CGRP inhibitors, given as daily tablets or  monthly/quarterly injections, have strong evidence and have helped many of our patients.
  • Botulinum toxin injections are recommended for chronic migraine, which means 15 or more headache days each month.

The Lifestyle
Side of Things

It may not sound exciting, but getting enough sleep, eating regular meals, drinking plenty of water, and building good stress-management habits really help many people.

A Few Questions
We Hear Often

Is migraine with aura dangerous? For most people, it is not. However, there is a slightly higher risk of stroke, especially in women who smoke or use estrogen-containing birth control. Your provider can help you determine your risk level.

Can aura happen without a headache? Yes, silent migraine is real. If you have sudden visual or neurological symptoms, get checked to rule out other causes.

Is Aura different from a TIA (mini-stroke)? Both can involve sudden visual or sensory symptoms. The key difference is onset: aura builds slowly over several minutes, while TIA symptoms tend to appear abruptly. When in doubt, especially with new or unusual symptoms, seek emergency evaluation.

Will my migraines get worse over time? Not always. Migraine patterns can change as you get older. With good management, many people are able to reduce how often and how severe their migraines are.

You Don’t Have to Manage This Alone

Migraine with aura is a well-understood neurological condition. It has a name, a clear explanation, and, most importantly, effective treatment options.

If you are in the Westmont area or anywhere in the western suburbs of Chicago and migraines are affecting your quality of life, we encourage you to come in for an evaluation.
