How Sumatriptan (Imitrex) works
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.

Pharmacist tips for Sumatriptan (Imitrex)
- You can take sumatriptan (Imitrex) with or without food. If it's hurting your stomach, try taking it with food to help.
- If you didn't get any migraine relief from your first dose of sumatriptan (Imitrex), don't take a second dose of medication without asking your provider first. It could mean that your headache isn't migraine-related and that it's caused by another condition.
- Sumatriptan (Imitrex) can sometimes make you feel sleepy or dizzy. Don't drive or do anything that requires a lot of attention until you know how this medication affects you.
- You might have a feeling of tightness, pressure, or pain in the chest, throat, jaw, or neck after taking sumatriptan (Imitrex). It typically doesn't last for long and will go away. However, these symptoms are very similar to symptoms of a heart attack or heart problems. If you notice that these symptoms are worsening or don't go away, get medical help right away.
- If you're having more than four migraines per month, let your healthcare provider know. It's not known whether it's safe to take sumatriptan (Imitrex) that often. If you have frequent migraines, you'll need to consider different medication options to help with your symptoms. In general, taking migraine medications for more than 9 days out of a month can lead to rebound headaches (also called medication-overuse headaches).
- Sumatriptan (Imitrex) interacts with many medications. These interactions can lead to dangerous side effects. Make sure to let your provider and pharmacist know about all the medications you're taking (including vitamins and supplements) before starting sumatriptan (Imitrex) so that they can help you check for interactions. If there are many interactions, your provider might even switch you to a different migraine medication.
Risks and warnings for Sumatriptan (Imitrex)
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.
Heart problems and high blood pressure
- Risk factors: History of heart problems | Age older than 65 | Diabetes | Obesity | High blood pressure | Smoking tobacco | Family history of heart disease
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.
Stroke or other brain injury
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.
Extreme narrowing of blood vessels
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.
Serotonin syndrome
- Risk factors: Taking other medications that raise serotonin levels in your brain
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
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.
Seizures
- Risk factors: History of seizures or epilepsy
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).
