Sumatriptan (Imitrex) is used to treat migraines with or without aura in adults. The medication is typically taken as a single dose for your migraine. But, it's possible that you can take it again 2 hours after the first dose if your migraine doesn't go away. Side effects of sumatriptan (Imitrex) include tingling or numbness of fingers or toes, feeling too warm or too cold, and fatigue. It can interact with antidepressants and other similar migraine medications. Sumatriptan (Imitrex) is available as a lower-cost generic tablet.
Sumatriptan (Imitrex) is a triptan. It works by attaching to and turning on serotonin receptors in the blood vessels and nerves in your brain. This causes the blood vessels to tighten as well as lower the release of proteins that cause inflammation and pain. This is thought to help relieve migraines.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.

It's generally considered safe to take sumatriptan (Imitrex) with acetaminophen (Tylenol) or nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil, Motrin). Sumatriptan (Imitrex), acetaminophen (Tylenol), and NSAIDs work completely differently to relieve migraines and don't appear to interact with each other. Taking sumatriptan (Imitrex) with acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) can potentially work even better to relieve migraines than taking any of these medications alone. But, keep in mind that these other pain relievers also have their own risks (e.g., liver risks, heart risks, kidney problems). Before using other pain medications with sumatriptan (Imitrex), speak with your healthcare provider to make sure it's safe for you to do so.
There are a few medications that you shouldn't take with sumatriptan (Imitrex). This is because certain drug interactions with sumatriptan (Imitrex) can be harmful. Don't take ergot-derivative medications, like dihydroergotamine (Migranal), and other triptans within 24 hours of sumatriptan (Imitrex). This combination can cause your blood vessels to become dangerously narrow, raise your blood pressure too much, and raise your risk of heart attack or stroke. Additionally, you shouldn't take sumatriptan (Imitrex) with certain antidepressants because of the risk of serotonin syndrome. Tell your provider and pharmacist about all the medications and over-the-counter products you're taking or planning to take. They can help check for interactions and make sure your medications are safe to take with sumatriptan (Imitrex).
You can take two doses of sumatriptan (Imitrex) within a 24-hour period to help treat a migraine. If you need to take two doses, make sure they're separated by at least 2 hours. In addition, only take sumatriptan (Imitrex) for up to 4 migraines in a 30-day period because it's not known how safe it is to take the medication too many times. If you're still having a migraine after taking two doses of sumatriptan (Imitrex) in a day or have already used the medication for 4 migraines in a month, speak to your provider about other treatment options to help. But, keep in mind that using migraine medications for 10 or more days per month can cause your headaches to come back and possibly be worse (rebound or medication-overuse headaches).
After you take a dose of sumatriptan (Imitrex), it can take about 10 hours for the medication to leave your body. Keep in mind that this time frame is estimated based on the half-life of sumatriptan (Imitrex). How long the medication stays in your body can be affected by your health conditions, so it might be different for each individual person. Discuss with your provider if you have questions about how long the medication stays in your body.
It's possible for sumatriptan (Imitrex) to make you sleepy, but it doesn't appear to be a common side effect. Only about 2% to 3% of people taking sumatriptan (Imitrex) reported feeling tired or fatigue as a side effect in clinical studies. Before driving or performing activities where you need to be alert, wait and see how this medication affects you.
Sumatriptan (Imitrex) can start to relieve pain and other migraine symptoms within 30 minutes to 2 hours. If you feel that a dose of sumatriptan (Imitrex) isn't enough to relieve your migraine symptoms, speak to your provider about your options.
Talk to your provider about using sumatriptan (Imitrex) if you're pregnant. It isn't completely clear how safe sumatriptan (Imitrex) is during pregnancy. Data from a pregnancy exposure registry and a medical birth registry didn't show a clear link between sumatriptan (Imitrex) and harm to babies. However, animal studies show babies were harmed when born to mothers exposed to sumatriptan (Imitrex). To be safe, it's best to always discuss the risks and benefits of using sumatriptan (Imitrex) during pregnancy with your provider.
Based on available data, sumatriptan (Imitrex) isn't expected to cause side effects in breastfed babies or affect breast milk production. But, the manufacturer of sumatriptan (Imitrex) recommends avoiding breastfeeding for at least 12 hours after taking a dose of the medication. Ask your provider if using sumatriptan (Imitrex) while breastfeeding is a safe option for you and your baby.
Sumatriptan (Imitrex) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Although rare, some people have reported serious heart problems, such as heart attack and heart rhythm problems, within a few hours after taking sumatriptan (Imitrex). In addition, sumatriptan (Imitrex) can raise your blood pressure, rarely to dangerously high levels. If you have a history of heart problems, talk to your provider first to make sure sumatriptan (Imitrex) is as safe for you as possible. Make sure to check your blood pressure periodically while you're taking sumatriptan (Imitrex), and let your provider know if it's higher than usual. Get emergency help right away if you experience a heart attack, severe headache, chest pain, or irregular heartbeat.
Some people who've taken triptans like sumatriptan (Imitrex) have experienced life-threatening strokes or bleeding in the brain. Symptoms of such brain injury include sudden weakness on one side of the body, bad headaches, drooping face, trouble breathing, or changes in your speech or vision. These symptoms can be similar to migraine symptoms, so strokes can be mistaken for a migraine. To lower the risk of making this mistake, it's important that you're properly diagnosed with migraines before you start sumatriptan (Imitrex). In addition, people who've had strokes before shouldn't take sumatriptan (Imitrex). If you notice symptoms of a stroke, stop taking sumatriptan (Imitrex) and get medical help as soon as possible, especially if you haven't had a migraine before.
Sumatriptan (Imitrex) can cause extreme narrowing of your blood vessels in certain parts of your body. This can lead to serious stomach problems (e.g., stomach pain, bloody diarrhea), vision problems, and changes in sensation in your hands and feet. It can also lead to color changes in your hands and feet (can turn pale or reddish depending on how much blood is flowing through). If you notice these symptoms after taking sumatriptan (Imitrex), don't take any more medication until you see a provider so they can check out what's going on.
Some people taking sumatriptan (Imitrex) have developed a rare, but potentially life-threatening condition called serotonin syndrome. This condition happens where there's too much serotonin in the brain. Your risk for serotonin syndrome goes up if you use sumatriptan (Imitrex) with other medications that can raise your serotonin levels, such as certain antidepressants, mental health medications, pain medications, and migraine medications.
Let your provider know about all the medications you take before starting sumatriptan (Imitrex), as well as any medications you plan to take. Symptoms of serotonin syndrome include fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion. Get medical help right away if you have any of these symptoms.
Allergic reactions to sumatriptan (Imitrex) are possible, including life-threatening reactions like facial swelling, shock, and anaphylaxis (closing of the throat). If you notice dizziness, difficulty breathing, a choking sensation, nausea, swelling around your eyes, or swelling of the lips or tongue after using sumatriptan (Imitrex), get medical attention as soon as possible.
Some people have had seizures after taking sumatriptan (Imitrex). This has happened in people who have a history of seizures, but can also happen in people who've never had them as well. Get medical help right away if you have a seizure while taking sumatriptan (Imitrex).
