Migraine Medication: A Complete Guide to Acute and Preventive Treatments

Migraine medication falls into two categories: acute treatments such as triptans, gepants, and NSAIDs that stop pain once an attack has started, and preventive treatments such as CGRP monoclonal antibodies, beta-blockers, and onabotulinumtoxinA that are taken on a schedule to reduce how often attacks occur. The American Headache Society recommends adding preventive therapy once a person reaches four or more migraine days a month, while acute treatment remains appropriate for every attack regardless of how often they occur [2].

Understanding Migraine Medication Categories

Treating migraine effectively requires understanding the two fundamental categories of medication. Acute (abortive) treatments are taken during an attack to relieve symptoms. Preventive (prophylactic) treatments are taken regularly, whether or not you have a headache, to reduce how often attacks occur and how severe they are [1]. Many patients with moderate to severe migraine benefit from both approaches working together.

The American Headache Society recommends considering preventive therapy when a patient experiences four or more migraine days per month, when attacks are significantly disabling, or when acute medications are not providing adequate relief [2].

Medication choice also depends on which type of migraine a person has. Migraine with aura, vestibular migraine, hemiplegic migraine, and ocular migraine all fall under the same broad diagnostic category but can call for different medication caution, since triptans and other vasoconstrictive drugs are generally avoided in hemiplegic migraine and migraine with brainstem aura. Readers still working out whether their symptoms fit the diagnosis may find it useful to compare migraine versus a regular headache before starting any medication plan, and the broader overview of migraine as a condition covers triggers and diagnosis in more depth.

Acute Migraine Medications

Triptans

Triptans have been the backbone of acute migraine treatment since sumatriptan was introduced in the early 1990s. They work by activating serotonin 5-HT1B and 5-HT1D receptors, which constricts dilated blood vessels and inhibits the release of inflammatory neuropeptides, including CGRP, or calcitonin gene-related peptide [3].

Seven triptans are currently available: sumatriptan, rizatriptan, eletriptan, zolmitriptan, naratriptan, almotriptan, and frovatriptan. They differ in how quickly they start working, how long they last, and how they are delivered [3]:

• Fastest onset: Sumatriptan injection (10 to 15 minutes), sumatriptan nasal spray (15 to 20 minutes), rizatriptan orally disintegrating tablet (30 minutes)
• Longest duration: Frovatriptan (half-life of 26 hours, making it useful for menstrual migraine prevention) and naratriptan (half-life of 6 hours)
• Best tolerated: Naratriptan and almotriptan tend to cause fewer side effects, though they may be slightly less potent

Common side effects include chest tightness, tingling, fatigue, and dizziness. Because triptans cause vasoconstriction, they are contraindicated in patients with coronary artery disease, uncontrolled hypertension, or a history of stroke [3]. For the same reason, prescribers typically steer away from triptans in hemiplegic migraine and migraine with brainstem aura.

Gepants (Small-Molecule CGRP Receptor Antagonists)

Gepants are a newer class of acute migraine treatment that block the CGRP receptor without causing vasoconstriction. This makes them a valuable option for patients who cannot take triptans due to cardiovascular risk [4]. Three gepants are currently approved for acute treatment:

• Ubrogepant (Ubrelvy): Oral tablet taken at onset of migraine, with an optional second dose after 2 hours
• Rimegepant (Nurtec ODT): Orally disintegrating tablet with a unique dual indication for both acute treatment and prevention
• Zavegepant (Zavzpret): Nasal spray offering faster onset than oral gepants

Clinical trials show gepants provide pain freedom at 2 hours in approximately 19 to 21 percent of patients compared to 11 to 14 percent with placebo [4]. While these numbers are modest compared to triptans, gepants carry no cardiovascular warnings and do not appear to cause medication overuse headache.

NSAIDs and Analgesics

Nonsteroidal anti-inflammatory drugs remain a first-line option for mild to moderate migraine attacks. Ibuprofen (400 to 800 mg), naproxen sodium (500 to 825 mg), and aspirin (900 to 1000 mg) all have evidence supporting their effectiveness [5]. Diclofenac potassium, available as a powder for oral solution, offers faster absorption than standard tablets.

For stronger acute relief, some physicians prescribe combination analgesics. The combination of acetaminophen, aspirin, and caffeine (sold as Excedrin Migraine in the US) is an FDA-approved over-the-counter option with good evidence behind it [5]. Caffeine enhances analgesic absorption and has mild vasoconstrictive effects that may help on their own.

Ditans (5-HT1F Receptor Agonists)

Lasmiditan (Reyvow) represents another option for patients who cannot take triptans. Unlike triptans, lasmiditan selectively activates the 5-HT1F receptor and does not cause vasoconstriction [6]. It is effective for acute migraine but causes significant dizziness and sedation in many patients. Driving and operating machinery should be avoided for at least 8 hours after a dose, and it is classified as a Schedule V controlled substance due to its CNS effects.

Antiemetics

Nausea and vomiting accompany migraine in many patients, making antiemetics an important part of acute treatment. Metoclopramide and prochlorperazine not only relieve nausea but also have independent antimigraine activity through dopamine receptor blockade [7]. In emergency department settings, IV prochlorperazine or metoclopramide is often more effective than opioids for acute migraine relief [7].

Preventive Migraine Medications

CGRP Monoclonal Antibodies

These biologic medications target either the CGRP molecule itself or its receptor and represent the first drug class developed specifically for migraine prevention. Four CGRP monoclonal antibodies are available [8]:

• Erenumab (Aimovig): Monthly self-injection targeting the CGRP receptor (70 mg or 140 mg)
• Fremanezumab (Ajovy): Monthly or quarterly self-injection targeting the CGRP ligand
• Galcanezumab (Emgality): Monthly self-injection targeting the CGRP ligand
• Eptinezumab (Vyepti): Quarterly IV infusion targeting the CGRP ligand, with the fastest onset of preventive benefit

Clinical trials consistently show that CGRP monoclonal antibodies reduce monthly migraine days by 3 to 5 days compared to 1 to 3 days with placebo [8]. Their side effect profile is relatively clean: injection site reactions and constipation (particularly with erenumab) are the most common complaints. Unlike older preventive medications, they do not cause weight gain, cognitive dulling, or sedation.

The main barriers are cost and access. Without insurance coverage, these medications can exceed $600 per month, though manufacturer assistance programs and biosimilar competition are beginning to improve affordability [8].

Beta-Blockers

Propranolol and metoprolol have the strongest evidence among beta-blockers for migraine prevention [9]. They are thought to work through modulation of central catecholamine activity and regulation of vascular tone. Propranolol at doses of 80 to 240 mg daily reduces migraine frequency by roughly 40 to 50 percent in responders [9].

Side effects include fatigue, exercise intolerance, cold extremities, depression, and sexual dysfunction. Beta-blockers are a particularly good choice for migraine patients who also have hypertension, performance anxiety, or essential tremor. They should be avoided in patients with asthma, severe bradycardia, or decompensated heart failure.

Anticonvulsants

Two anticonvulsants, also called antiepileptic drugs (AEDs), have strong evidence for migraine prevention:

Topiramate (Topamax) is FDA-approved for migraine prevention at doses of 50 to 100 mg daily. It reduces migraine frequency effectively but carries a notable side effect burden, including cognitive difficulties (often called “brain fog” or “dopamax” by patients), paresthesias, weight loss, kidney stones, and metabolic acidosis [10]. It is teratogenic and absolutely contraindicated in pregnancy.

Valproate/divalproex sodium (Depakote) is also FDA-approved and effective at doses of 500 to 1500 mg daily. Side effects include weight gain, tremor, hair loss, and liver toxicity. Like topiramate, it is teratogenic and requires reliable contraception in women of reproductive age [10].

Antidepressants

Among antidepressants, amitriptyline (a tricyclic) has the most evidence for migraine prevention, typically used at doses of 10 to 75 mg at bedtime, well below the doses used for depression [11]. It is particularly useful for patients with comorbid insomnia or tension-type headache. Common side effects include dry mouth, weight gain, constipation, and morning drowsiness.

Venlafaxine (an SNRI) at doses of 150 mg daily is another option with moderate evidence, and it may be better tolerated than tricyclics in some patients [11]. SSRIs (like fluoxetine and sertraline) have weak evidence for migraine prevention and are generally not recommended as primary preventive therapy.

OnabotulinumtoxinA (Botox)

Botox injections are FDA-approved specifically for chronic migraine (15 or more headache days per month). The PREEMPT protocol involves 31 to 39 injections across 7 specific head and neck muscle sites every 12 weeks [12]. Response may take two to three treatment cycles to become apparent.

Botox works through inhibition of peripheral nociceptive signaling and has been shown to reduce headache days by 8 to 9 per month in chronic migraine patients [12]. It is generally well tolerated, with neck pain and injection site discomfort being the most common complaints. It is not typically effective for episodic migraine (fewer than 15 headache days per month).

Comparing Migraine Medication Options

Each major medication class is built for a different stage of a migraine attack and a different pattern of use. The table below summarizes how the options described above compare on category, mechanism, and how they are typically taken.

This comparison is a starting point for a conversation with a prescriber, not a substitute for one. A neurologist or headache specialist weighs attack frequency, comorbidities, and prior response before recommending a specific class, and people exploring providers who manage these medications alongside other options can review the directory of migraine treatment providers or the broader migraine treatment guide for context on what each approach involves.

How to Choose the Right Migraine Medication

Selecting a migraine medication is a collaborative process between you and your physician. Several factors guide the decision [2]:

• Attack frequency: Fewer than 4 migraine days per month may be managed with acute treatment alone. More frequent attacks warrant adding prevention.
• Comorbid conditions: Hypertension favors beta-blockers. Depression may favor antidepressants. Epilepsy may favor anticonvulsants. Cardiovascular disease rules out triptans.
• Side effect profile: Weight concerns may steer away from valproate or amitriptyline. Cognitive concerns argue against topiramate.
• Speed of onset needed: CGRP antibodies and Botox work slowly. Patients needing rapid results may prefer medications with faster onset of preventive benefit.
• Route of administration: Some patients prefer daily pills. Others prefer monthly injections they do not have to remember each day.
• Cost and insurance coverage: Older generic medications (beta-blockers, tricyclics, topiramate) are far less expensive than CGRP antibodies or gepants.

A side-by-side read of migraine treatment options alongside this medication guide can help frame these tradeoffs, and a headache specialist can translate them into a specific plan faster than trial and error alone.

Medication Overuse Headache: A Critical Warning

One of the most important concepts in migraine management is medication overuse headache (MOH), previously called rebound headache. Using acute migraine medications too frequently, typically more than 10 days per month for triptans or opioids, or more than 15 days per month for simple analgesics, can paradoxically worsen headache frequency and severity [13].

MOH affects an estimated 1 to 2 percent of the general population and up to 50 percent of patients in headache specialty clinics [13]. The treatment involves carefully withdrawing the overused medication (often with a bridge therapy like a short steroid taper or nerve block) and starting appropriate preventive therapy. Gepants and CGRP antibodies appear to carry a lower risk of MOH compared to older acute treatments, though long-term data are still accumulating [4]. Readers tracking their own attack and medication days may find the practical strategies in this site's migraine relief guide useful for staying under these thresholds.

Newer and Emerging Treatments

The migraine treatment landscape continues to evolve. Atogepant (Qulipta), an oral gepant taken daily for prevention, has shown efficacy in both episodic and chronic migraine and offers a convenient oral preventive option for patients who prefer pills over injections [14]. Dual-mechanism devices combining neuromodulation with pharmacotherapy are in development. Research into glutamate receptor modulators, pituitary adenylate cyclase-activating polypeptide (PACAP) inhibitors, and other novel targets may yield additional treatment options in the coming years [15].

Migraine Medication During Pregnancy and Breastfeeding

Pregnancy changes the medication calculus substantially. Acetaminophen is generally considered the first-line acute option during pregnancy, while NSAIDs are typically avoided, especially in the third trimester, because of risks to fetal circulation. Data on triptan safety in pregnancy are more reassuring for sumatriptan specifically than for the other six triptans, and most CGRP monoclonal antibodies and gepants have not been studied enough in pregnant patients to support routine use.

Preventive medication choices narrow further. Topiramate and valproate are both teratogenic and are avoided in pregnancy and in anyone who could become pregnant without reliable contraception [10]. Beta-blockers and low-dose amitriptyline have a longer track record and are sometimes continued under close obstetric supervision when prevention is necessary. Anyone who is pregnant, trying to conceive, or breastfeeding should review every migraine medication, acute or preventive, with both their obstetric provider and their neurologist or headache specialist rather than adjusting a regimen alone.

Beyond Medication: Complementary and Procedural Approaches

Medication is rarely the only tool in a migraine treatment plan. Noninvasive neuromodulation devices, including external trigeminal nerve stimulation, remote electrical neuromodulation, and noninvasive vagus nerve stimulation, are FDA-cleared options that some patients use alongside or instead of drugs, particularly when medication side effects or contraindications limit their choices. Biofeedback therapy and providers offering neurofeedback-based care teach patients to influence physiological responses, such as muscle tension and skin temperature, that are linked to attack frequency in some people.

Diet and gut health are two areas patients frequently ask about. Identifying individual dietary triggers, covered in more detail in this site's migraine diet guide, and addressing gut-related contributors discussed in the migraine and gut health article, are reasonable complements to a medication plan rather than replacements for one. People weighing procedural or device-based options alongside medication can use the migraine treatment clinic directory to see which nearby providers offer each approach, keeping in mind that inclusion in a directory listing reflects the information a provider has supplied and verified, not an endorsement of outcome for any individual patient.

Frequently Asked Questions

What is the newest medication for migraine?

The most recently developed options are the gepants, small-molecule CGRP receptor blockers. Zavegepant (Zavzpret), a nasal spray, and atogepant (Qulipta), a daily oral preventive, are among the newest approved treatments, joining ubrogepant and rimegepant. All four avoid the vasoconstriction associated with triptans, which is why they are often considered for patients with cardiovascular risk factors [4][14].

What is the most commonly prescribed medication for an active migraine attack?

Triptans remain the most widely prescribed class for an attack already underway, a position they have held since sumatriptan's introduction in the early 1990s. Seven triptans are available in the United States, and prescribers typically match the specific drug and delivery method to how quickly a person needs relief and how long their attacks tend to last [3].

Can I take migraine medication every day?

Daily preventive medications, such as beta-blockers, anticonvulsants, antidepressants, or CGRP monoclonal antibody injections given on a monthly schedule, are designed for regular use. Acute medications are different: taking triptans or opioids more than about 10 days a month, or simple analgesics more than about 15 days a month, risks medication overuse headache, a condition that can make attacks more frequent over time [13].

What over-the-counter medication works best for migraine attacks?

NSAIDs such as ibuprofen and naproxen sodium, aspirin, and the combination product acetaminophen plus aspirin plus caffeine (sold as Excedrin Migraine) are the main over-the-counter options with supporting evidence. They tend to work best for mild to moderate attacks treated early, and people whose attacks do not respond adequately to them should discuss prescription options with a physician [5].

Is Botox used for every type of migraine?

No. OnabotulinumtoxinA is FDA-approved specifically for chronic migraine, defined as 15 or more headache days per month. It is not typically effective for episodic migraine, meaning fewer than 15 headache days per month, and most patients need two to three treatment cycles, spaced 12 weeks apart, before judging whether it is working [12].

How long does it take for preventive migraine medication to start working?

Timelines vary by class. Some CGRP monoclonal antibodies can reduce migraine days within the first month, which is faster than most older preventives [8]. Beta-blockers, anticonvulsants, and antidepressants are generally given an extended trial at an adequate dose before being judged ineffective, since benefit can build gradually [9][10][11]. OnabotulinumtoxinA typically needs two to three injection cycles, spaced 12 weeks apart, before its full effect becomes clear [12].
