Beyond Botox: How CGRPs and Gepants Are Changing the Migraine Landscape
Migraines are undoubtedly one of the worst forms of a headache, and experiencing one can be debilitating. But that’s not the worst aspect of migraines. It’s the canceled plans and feeling like you are shaping your life around the next attack. It’s the feeling that you have tried almost everything, but nothing works.
Supplements, lifestyle changes, repurposed preventatives, botox, triptans, and yet, that ever-present exhaustion from the “let’s try this next” cycle.
The good news is that the treatment landscape has changed significantly in the last few years, and there are now migraine-specific therapies designed to target the biology of migraines more directly. This means no more guessing and hoping; these treatments are rooted in science.
This article will explore what calcitonin gene-related peptides (CGRPs) and Gepants are, how they relate to headaches, and why this therapy shows a lot of promise compared to tried-before methods.
Understanding the “Migraine Switch”: What CGRP Actually Does
Migraines have been a medical mystery for more than 3,000 years, and can be traced back as far as 1,200 B.C. There have been many theories, ranging from superstitions to psychological causes. Today, despite ongoing research, we have identified a neuropeptide in the nervous system, CGRP, that has shed light on what happens during a migraine.
CGRPs, or calcitonin gene-related peptides, are proteins that act as neurotransmitters in the nervous system. The basic process of a migraine looks something like:
One of the earliest changes in a migraine is a slow wave of disrupted brain activity, which can help explain why an attack often feels like it is building before the pain fully hits.
If this wave irritates the Trigeminal Nerve, it sets off the pain pathway involved in many migraine attacks.
Those nerve endings release neuropeptides, which include CGRP, this in turn drives the attack.
That process amplifies inflammation and pain signaling, which is part of what creates the throbbing, overwhelming pain many people feel during a migraine.
You could think of CGRPs as the fuel on the fire. This wave might cause some pain or irritation, but it’s the CGRPs that exacerbate everything.
As for what causes a migraine in the first place, it could be:
Metabolic changes
Sensory overload
Sleep disruptions
Fluctuating hormone levels
The migraine brain that reacts strongly to both internal or external changes. This leads researchers to believe that some people are likely more prone to migraines than others.
Why a New Generation of Migraine Medication Feels Different
The main reason why newer migraine medications feel different is because older medications or treatments were borrowed. For many patients, that meant cycling through treatments that were not originally designed for migraine in the first place. Most treatments were in fact "successful accidents”; older treatments helped some patients, but they were never designed for migraines specifically.
For example, previous treatments included beta-blockers, anticonvulsants, antidepressants, etc. Each of these were prescribed for a different original purpose, ranging from high blood pressure to depression.
It was only in 2010, when botox was approved by the FDA for chronic migraines that a major shift occurred. This marked the first time that a treatment that focused on the sensory nerves themselves was prescribed. However, you needed to have 15+ migraines per month to qualify, and required 31 injections every 12 weeks.
None of the treatments were promising and none focused specifically on the biology of migraines.
However, in 2018, the first CGRP-related medications were released. These medications (Aimovig, Emgality, Ajovy, etc) were all designed specifically to block the protein that causes the pain experienced from a migraine.
This doesn’t mean that these CGRP blockers are a cure-all for everyone, but they are still the most effective form of treatment for migraines.
CGRP Inhibitors: The Injectable Preventive Option
CGRP monoclonal antibodies are preventive migraine treatments. They are designed to reduce how often migraine attacks happen over time. They are not same-day rescue medications meant to stop a single attack in real-time. Their role is long-term prevention.
These therapies are laboratory-made antibodies that target the CGRP pathway. Some bind directly to the CGRP molecule, while others block the receptor it would normally attach to. Several are used in migraine prevention, and depending on the product, dosing may be monthly or follow another schedule recommended by the treating specialist.
This is where many patients naturally compare them to Botox. Botox is still an established and valuable option, especially for some people with chronic migraine. It has not become irrelevant. But CGRP-targeting therapies have expanded the toolkit. For patients who have not had enough relief with older preventives, or who have already been through other treatment pathways, these injectables offer another migraine-specific option to consider.
The important point is not that injectables are “better” in a blanket sense. It is that they are different. They reflect a more targeted understanding of migraine prevention, and for the right patient, that can matter a great deal.
Gepants: The New Oral Treatment Changing Migraine Care
Many people aren’t keen on the idea of chronic injections, as they can be quite a hassle. The good news is that new oral treatments exist, and they work a bit differently to their injectable counterparts.
Injectables: You can think of the injectables as a mop. They basically clean up all the GCRP molecules before they reach a nerve by circulating in the blood.
Oral Geptants: You can think of oral treatments as a lock on the GRCP molecules. This is because they sit on the molecules and make it impossible for them to “plug in”, which prevents the pain signal for occurring.
There are other differences, for example, the speed of action and duration.
Injectables: Because these are large molecules that the body slowly breaks down, they are always active and can last up to 3 months. But, they don’t work immediately once taken, so they can’t reduce pain in the middle of an attack if you just took one.
Orals: The Gepants move through your system quickly as they are processed by the liver. They work immediately and can provide immediate relief, even during an attack. However, it also means they leave your system within 24 hours.
For many, the difference between triptans (the older oral rescue method) and new Gepants isn’t clear. They definitely share similarities; both were designed to provide immediate relief. However, there are differences in immediacy and risk factors.
Triptans: While they provide immediate relief during an attack, you could develop rebound headaches if taken too frequently. They also can’t be taken by anyone with heart disease, a history of stroke, or high blood pressure as they narrow blood vessels.
Gepants: These also work immediately during an attack, but they can be taken as a preventative as well since they don’t cause overuse headaches. Additionally, since they don’t narrow blood vessels, they’re a safer option for a wider group of patients.
Whether you require injectables or the oral treatment, largely depends on the frequency of your migraines.
Why Migraine Treatment Is No Longer One-Size-Fits-All
Whenever a new class of medication gets attention, there is a temptation to reduce the conversation to “old versus new.” But migraine care is rarely that simple.
Botox still helps many patients with chronic migraine due to targeting sensory nerves. Triptans still work well for many people as they prevent several inflammatory neuropeptides from releasing and have a longer pain-reduction period than Gepants.
Older preventive medications are still useful in the right setting. For example, if a patient suffers from insomnia and chronic migraines, Amitriptyline (antidepressant) has shown great efficiency at treating both. Newer CGRP inhibitors and Gepants do not erase those options, they simply expand the landscape.
The right treatment plan depends on far more than whether a therapy is newer. Migraine frequency matters. Symptom pattern matters. Trigger patterns matter. Previous medication response matters. Medical history matters. Cardiovascular risk matters. Patient preference matters. Some patients need better acute control. Others need stronger prevention. Some need both. Some may benefit from procedural treatment, medication, lifestyle support, or a combination of these.
That is why specialist headache care matters. The real goal is not to hand every patient the same “advanced” therapy. The goal is to understand which path makes sense for that person’s migraine profile.
Moving Beyond Trial and Error With Precision Neurology
It’s safe to say that for many people suffering from chronic migraines that neurology has been an experience of one failed prescription after another. A new medication brings hope, then disappointment, then the search starts again. But, newer migraine care has become a lot more targeted in recent years.
This is evident from medications being prescribed that happened to reduce the frequency of migraines, to now specific solutions being developed with only migraines in mind.
Precision care sounds like a buzzword used by medical companies, but it really means looking at the:
Frequency
Intensity
Pattern
Triggers
Treatment goals
Coexisting conditions
Previous medication responses
To provide the best care to live a life without migraines. It also includes deciding whether you need acute treatment, prevention, procedural options, or a combination of the above.
There is no one-size-fits-all approach to migraine care, which is why specialist evaluation matters. Dr. Natalie Hendon assesses attack pattern, treatment history, coexisting conditions, and patients goals before deciding on a treatment plan that fits a patient’s specific migraine profile.
This is the most important aspect of migraine treatment, since a good care plan does more than only reacting during attacks. It tracks patterns over time so the treatment provided can adapt for best results.
Safety, Evidence, and the Importance of Specialist Guidance
The newer medications used for the treatment of migraines have all gone through rigorous formal clinical development and reviews. What does this mean for you? It means that they are not like the “off-label” guesswork of the past. They are built on decades or peer-reviewed neurological research. However, even though they have generally excellent safety profiles, as established above, they are not “one-size-fits-all”.
With that said, their prescription still requires clinical judgement in terms of:
Personal medical history
Suitability
Safety
Interactions with other medications
Insurance
Dr. Natalie Hendon must carefully evaluate all patients. This is even more important for patients that have a history of cardiovascular disease or are planning a pregnancy, because some injectables can stay in the system for months.
These treatments are usually assessed over a 12-week period, with the aim of seeing a meaningful reduction in migraine frequency. If that improvement does not happen, treatment should not simply continue unchanged. This is where Dr. Natalie Hendon’s role becomes important: evaluating response, side effects, and overall migraine pattern to decide whether another CGRP-targeting therapy or a different strategy is more appropriate.
Another consideration is that insurance companies in certain regions may not cover newer CGRP therapies until a patient has tried at least two or three more traditional treatment options.
Who Might Be a Candidate for CGRP or Gepants Therapy?
In terms of who might be a candidate, there are many factors that are considered. These are usually patients who:
With that said, their prescription still requires clinical judgement in terms of:
have tried multiple preventatives without enough relief
have already tried Botox and still struggle
need a non-injectable option
cannot tolerate triptans or have reasons to avoid vasoconstrictive drugs
feel overwhelmed by mixed information online
want a clearer long-term migraine management plan
If this sounds like you, the best way to actually determine if you qualify as a candidate is to talk to a professional like Dr. Natalie Hendon. She will go over things like:
Documented "treatment failure" history
Side effect intolerance
Cardiovascular health screening
Family planning and pregnancy timeline
Gastrointestinal and absorption issues
Menstrual and hormonal patterns
Baseline attack frequency
Functional goals vs. pain scores
Current rescue medication use
There is no guaranteeing who may qualify, so a consultation is always the best approach for peace of mind.
Modern Science, Specialized Care
If you have been suffering from chronic migraines, that may no longer need to be the case. Migraine treatment has evolved significantly over the last few years. You no longer need to figure out things like CGRPs, botox, Gepants, and rescue options on your own.
The best way to determine the path forward is to undergo a Migraine Management review which can help determine whether you will be prescribed the newer-generation therapies, depending if they fit your pattern and history.
Once you have had a consultation with Dr. Natalie Hendon, you will be able to more accurately determine an approach to live a migraine-free life.
In the meantime, you may want to read up on botox as a potential treatment plan if you experience more than 15 migraines per month.
