What happens when you see a doctor about migraine

Your doctor will start by asking detailed questions about your headaches: when they happen, how long they last, what they feel like, and what makes them better or worse. They may also ask about nausea, sensitivity to light or sound, or other symptoms that come with the pain. This conversation is the most important part of diagnosis—there is no blood test or scan that confirms migraine, so your description of the headaches is what guides treatment.

After listening to your history, your doctor may do a physical exam and possibly order imaging (like an MRI or CT scan) if your headaches are new, severe, or different from your usual pattern. In most cases, imaging is not needed. Once your doctor understands your migraine pattern, they will discuss treatment options with you. Treatment falls into two categories: stopping a migraine once it starts, and preventing migraines from happening in the first place.

Key Takeaways

  • Acute medications stop a migraine in progress and work best when taken early, within the first hour of pain starting.
  • Preventive medications reduce how often migraines happen and are taken daily even when you do not have a headache.
  • Over-the-counter options like ibuprofen or naproxen work for some people, but prescription medications are often more effective for moderate to severe migraine.
  • Triptans are a common first-line prescription for acute migraine and come in tablets, nasal sprays, and injections.
  • If one treatment does not work after a fair trial, your doctor can switch you to another—finding the right medication often takes time.

Acute medications: stopping a migraine when it starts

Acute medications are taken during a migraine to relieve pain and other symptoms. They work best when you take them as soon as the headache begins—waiting an hour or more makes them less effective. Your doctor may recommend starting with an over-the-counter option like ibuprofen (Advil, Motrin) or naproxen (Aleve), especially if your migraines are mild to moderate.

If over-the-counter medications do not work or your migraines are more severe, your doctor may prescribe a triptan. Triptans narrow blood vessels and block pain pathways in the brain. Common triptans include sumatriptan (Imitrex), rizatriptan (Maxalt), and zolmitriptan (Zomig). They come as tablets you swallow, nasal sprays, or injections. Most people feel relief within 30 to 60 minutes. If one triptan does not work for you, your doctor can try a different one—people respond differently to each medication.

Other acute options include combination medications (like acetaminophen plus caffeine), ergot derivatives (an older class of migraine drugs), and newer medications called CGRP antagonists (such as ubrogepant or rimegepant), which block a protein involved in migraine pain. Your doctor will choose based on your migraine severity, how quickly you need relief, and any other health conditions you have.

Preventive medications: reducing how often migraines happen

If you have migraines more than four times a month, or if acute medications are not working well enough, your doctor may recommend a preventive medication. These are taken daily, whether or not you have a headache, to reduce how often migraines occur and how severe they are. Preventive medications work gradually—you may not notice improvement for two to four weeks, and full benefit can take two to three months.

Common preventive options include beta-blockers (propranolol, timolol), which slow your heart rate and reduce blood vessel changes; tricyclic antidepressants (amitriptyline), which affect brain chemicals involved in pain; and anticonvulsants (topiramate, valproic acid), which calm overactive nerve activity. Your doctor chooses based on your other health conditions, other medications you take, and side effects you can tolerate.

Newer preventive medications called CGRP monoclonal antibodies (erenumab, fremanezumab, galcanezumab) have shown strong results for people with frequent migraines. These are injected monthly or quarterly and work by blocking a protein called CGRP that plays a role in migraine. They are typically prescribed after other preventives have been tried, though your doctor may start with them if your migraines are very frequent or severe.

Botulinum toxin (Botox) for chronic migraine

If you have chronic migraine—defined as 15 or more headache days per month—your doctor may discuss botulinum toxin injections (Botox). This treatment involves injections into specific muscles of the head and neck every 12 weeks. The exact way it prevents migraine is not fully understood, but it appears to block pain signals. Studies show it reduces headache days by about 50% in people who respond to it.

Botox for migraine is covered by most insurance plans when other preventive medications have not worked or have caused side effects. The procedure takes about 15 minutes and is done in a doctor's office. Results usually appear after one to two weeks and improve over a month. If it works for you, you will need ongoing injections to maintain the benefit.

Lifestyle changes and non-medication approaches

While medication is the main treatment, certain habits can reduce migraine frequency or severity. Keeping a consistent sleep schedule, staying hydrated, eating regular meals, and managing stress all help some people. Some find that regular aerobic exercise (like walking, swimming, or cycling) reduces migraines over time. Avoiding known triggers—such as certain foods, caffeine, alcohol, or hormonal changes—also matters.

Non-medication approaches like cognitive behavioral therapy (a type of counseling that helps change thought patterns), relaxation training, and biofeedback have evidence supporting their use, especially when combined with medication. Acupuncture has mixed evidence; some studies show benefit while others do not. Talk to your doctor about which approaches might complement your medication plan.

What to expect when starting a new medication

When your doctor prescribes a new migraine medication, they will explain how to take it, when to expect results, and what side effects to watch for. For acute medications, you may be told to take it as soon as a migraine starts, or to wait and see if it gets worse first. For preventive medications, you will take a dose every day, usually in the evening, and should not expect full benefit for several weeks.

Side effects are common but often improve with time. Triptans may cause tingling, flushing, or chest tightness (usually mild and brief). Preventive medications like amitriptyline can cause drowsiness or dry mouth; topiramate may affect memory or cause tingling in the fingers and toes. If side effects are bothersome or do not improve, tell your doctor—they can adjust the dose or switch you to a different medication. Finding the right treatment often takes trial and adjustment, and that is normal.

When to see a migraine specialist

Most migraines can be managed by your primary care doctor, but a neurologist or headache specialist may help if your migraines are frequent, severe, or not responding to standard treatments. Specialists have access to a wider range of medications and can manage complex cases—for example, if you have other neurological conditions or take many other medications that might interact.

You might ask for a referral to a specialist if you have tried two or more preventive medications without success, if your migraine pattern has changed significantly, if you are having medication overuse headaches (from taking acute medications too often), or if you want to explore newer treatments like CGRP monoclonal antibodies or Botox. A specialist can also help if your diagnosis is unclear or if your migraines come with unusual symptoms.

Frequently Asked Questions

How long does it take for preventive migraine medication to work?

Most preventive medications take two to four weeks to show any benefit, and full effect may not appear for two to three months. This is why your doctor will ask you to stay on the medication for at least that long before deciding whether it is working. Keep a headache diary during this time to track changes in frequency and severity.

Can I take acute migraine medication every day?

Taking acute medications more than 10 to 15 days per month can lead to medication overuse headache, where the medication itself triggers more frequent headaches. If you find yourself using acute medication very often, talk to your doctor about starting a preventive medication instead. Your doctor may also recommend a brief period without the medication to reset your system.

What if my migraine medication stops working?

Medications sometimes become less effective over time, a process called tachyphylaxis. If this happens, your doctor may increase the dose, switch you to a different medication in the same class, or try a completely different approach. Do not stop taking the medication on your own—work with your doctor to plan the next step.

Are migraine medications safe to take during pregnancy?

Some migraine medications are considered safer in pregnancy than others. Acetaminophen and certain triptans have been used in pregnancy with reassuring safety data, while some preventive medications should be avoided. If you are pregnant or planning to become pregnant, tell your doctor before starting or continuing any migraine medication so you can discuss the risks and benefits together.

Why do different migraine medications work for different people?

Migraine involves complex brain chemistry, and people's brains respond differently to the same medication. Genetics, other health conditions, and individual differences in how your body processes drugs all play a role. This is why your doctor may need to try more than one medication to find what works best for you.
