A few years ago, the phrase “nasal sprays” probably made you think of commercials for allergy medications. Yep, we can picture that bee too. Now that more and more nasal sprays made for treating migraine are hitting the market, however, you’re likely starting to get curious about how they actually work.
So we did the research and wrote this guide to answer all of your questions.
How do nasal sprays work to treat migraine?
First thing’s first: How do nasal sprays work in general?
Well, when you spray a treatment into your nose, the medication gets absorbed into the blood vessels in your nostril. After that, it’s just like what happens when you take a pill—the medication travels where it needs to go via your bloodstream. So to answer your question, the mechanics of the spray aside, they treat your migraine similar to the way that an oral pill would.
What are the benefits of nasal sprays?
Why would someone choose to spray a medication into their nose when they could just take a pill and get the same effect?
Nasal sprays work faster
Nasal sprays usually work more quickly than pills because you don’t have to wait for them to be dissolved and digested by your stomach, a process that slows during a migraine attack.
Experts call the time it takes for a medication to kick in “time to peak effect,” so nasal sprays have a shorter time to peak effect than tablets do.
For example, if you take a zolmitriptan tablet as soon as you feel a headache setting in, you could expect to get some relief from your symptoms in about 30 minutes. But if you use Zomig® nasal spray (the same medication, but in nasal spray form), you can get that relief in as little as 15 minutes.
If you’ve experienced a migraine headache, you know exactly what a big difference 15 minutes can make.
Nasal sprays can be more effective
The other factor experts consider when choosing what form to recommend is bioavailability, which means how much of the medication enters your blood circulation after you take it. (That’s right—some of what you put into your body never makes it to your bloodstream, which is why vitamins and supplements tend to use higher dosages that you actually need.)
Tablets have the lowest bioavailability, and IV treatments unsurprisingly have the highest. (Fun fact: Orally-dissolving tablets actually take longer to work than standard ones.) Nasal sprays are on the higher end of the spectrum. That means they not only work faster, but are also more efficiently absorbed by your body.
Nasal sprays don’t interfere with your nausea
And for people who experience migraine nausea, nasal sprays have an added benefit: You don’t have to swallow them ... or worry about vomiting and wasting medication.
What nasal sprays are currently available?
So far, three different types of nasal sprays that can treat migraine have hit the market. They’re all acute treatments (meaning they relieve symptoms but don’t prevent attacks), but they each work a little bit differently.
Like all triptans, nasal triptans relieve migraine symptoms by narrowing overexpanded blood vessels and reducing inflammation in the brain. The nasal triptans that are currently available include Tosymra® (generic sumatriptan) and Zomig® (generic zolmitriptan).
Nasal dihydroergotamine (DHE)
Dihydroergotamine is a formulation of ergotamine, a type of medication that also narrows blood vessels in the brain. (We’ll give you a second to digest those two SAT words.) Ergotamine is a natural product of a certain type of fungus. Medically, it’s used to treat migraine and cluster headaches. Dihydroergotamine is just ergotamine with hydrogen added to make it more potent.
The only drug of this class that’s been approved for migraine treatment so far is Migranal® (generic dihydroergotamine mesylate).
Nasal ketorolac provides a helpful alternative for migraine sufferers with cardiovascular conditions. (It’s risky to take medication that constricts blood vessels, like triptans and DHE, if you have any health conditions that affect your blood circulation.) Ketorolac is a type of non-steroidal anti-inflammatory drug (NSAID), a class of pain relievers. Unlike triptans and DHE, nasal ketorolac isn’t currently FDA-approved to treat migraine, just pain.
One example of a nasal ketorolac you can buy now is Sprix® (generic ketorolac tromethamine).
How do I use nasal sprays?
Like all acute treatments, nasal sprays work best when you take them as soon as you feel a migraine attack coming on. While you might be tempted to follow the advice the school nurse gave you when you got a nosebleed, you actually shouldn’t tip your head back. Doing so makes the medication drip down your throat and get absorbed by your stomach, which slows down the absorption process. For the same reason, try not to sniff too much while the spray is in your nose.
Since each use should administer a pre-measured amount of medication, you don’t need to worry much about dosage. Just be sure not to use the medication more often than you’re directed to.
Can I use nasal sprays with traditional migraine medication?
One of the benefits of nasal sprays is that they work quickly enough to be a great option for a back-up medication to use when your first-line treatment just isn’t enough. But not all nasal sprays and oral medications can be safely combined.
Regardless of form, different types of triptans can’t be mixed, so don’t use a triptan nasal spray if you’ve already taken an oral triptan. DHE and triptans also shouldn’t be used together.
On the other hand, NSAIDs and DHE are not only safe to combine, but are also thought to enhance each other’s effect when used together. You can also safely use triptans alongside NSAIDs.
As always, your doctor is the best person to talk to if you have any questions about specific medication combinations.
What are the side effects of migraine treatment nasal sprays?
Like all medications, nasal sprays can come with side effects. Common side effects include:
- dry mouth
- drowsiness or fatigue
- nausea or vomiting
- pain, pressure, or tightness in the nose, throat, or chest
- stuffy or runny nose
- tingling sensation, numbness, or skin sensitivity, especially around the nose
- unusual taste
Anything else I should know before trying nasal sprays?
Talk to your doctor before trying a nasal spray for migraine treatment if you’re pregnant or breastfeeding, and if you have high blood pressure, cardiovascular issues, or kidney problems.
Like other recent innovations in migraine treatment, nasal sprays give you a promising new option to consider when you’re building your treatment plan. For people whose migraine attacks tend to get very severe very quickly, nasal sprays could make a great first-line treatment. And even if that doesn’t describe you, it might not hurt to have a spray as a back-up for your preferred treatment.
