How Sumatriptan injection (Imitrex) works
Sumatriptan injection (Imitrex) is a triptan. It works on receptors in your brain and nervous system that respond to serotonin, a natural chemical in your body that's thought to play a role in migraines and headaches.
When it attaches to the serotonin receptors in the brain, sumatriptan injection (Imitrex) tightens the blood vessels in the brain and lessens blood vessel swelling that can cause migraine and headache pain. The medication also stops the release of other pain signals through your nervous system. This helps relieve migraine and headache pain.

Pharmacist tips for Sumatriptan injection (Imitrex)
- Your prescriber or pharmacist will train you on how to prepare and use the sumatriptan prefilled syringes and pen or vials, depending on which one you're prescribed. Ask your care team if you're not comfortable with how to prepare and take the medication.
- Inject sumatriptan injection (Imitrex) under the skin, typically in the side of your upper arm or thigh. Never inject the medication into a muscle or vein.
- It's best to inject sumatriptan injection (Imitrex) as soon as your migraine or headache starts. But you can also inject the medication at any time during your migraine or headache attack.
- If your migraine or headache comes back or if it doesn't completely go away after at least 1 hour of taking sumatriptan injection (Imitrex), you can take a second dose of the medication. Don't take a second dose of sumatriptan injection (Imitrex) any sooner than 1 hour from your previous dose; this can cause more side effects.
- It's possible for you to feel sleepy, dizzy, or weak after you take sumatriptan injection (Imitrex). Don't drive or do anything that requires concentration after you take a dose until you know how this medication affects you.
- Avoid alcohol after you take a dose of sumatriptan injection (Imitrex). Alcohol can worsen side effects like sleepiness and dizziness. It can also raise your risk of having another migraine.
- You might have a feeling of tightness, pressure, or pain in the chest, throat, jaw, or neck after you take sumatriptan injection (Imitrex). It typically doesn't last long and will go away. But keep in mind that these symptoms are very similar to symptoms of a heart attack or other heart problems. Get medical help right away if you notice that these symptoms are worsening or if they don't go away.
- Speak with your prescriber if you have migraines or cluster headaches very often. In general, taking migraine medications for more than 9 days out of a month can lead to rebound headaches (also called medication overuse headaches). Your prescriber can discuss with you about other ways to relieve your migraine or headache without the use of medications.
- Talk to your prescriber about the risks and benefits of taking sumatriptan injection (Imitrex) if you're pregnant. It isn't completely clear how safe the medication is during pregnancy.
- Ask your prescriber about taking sumatriptan injection (Imitrex) while breastfeeding. Based on research, the medication isn't expected to cause side effects in breastfed babies or affect your breast milk supply. But the manufacturer of sumatriptan injection (Imitrex) recommends avoiding breastfeeding for at least 12 hours after you take a dose of the medication to be safe.
- Store sumatriptan injection (Imitrex) at room temperature. Keep the medication in the original container to protect it from light.
Common questions about Sumatriptan injection (Imitrex)
It's recommended that you take sumatriptan injection (Imitrex) up to 9 days within a month only. This is because taking migraine medications for 10 or more days per month can raise the risk that your headaches can come back and possibly be worse. This worsening of headaches is called rebound or medication overuse headaches. Ask your prescriber about other treatment options to help if you still have a migraine or headache after you've already taken sumatriptan injection (Imitrex) or other headache medication for 9 days within a month.
You can take up to two doses of sumatriptan injection (Imitrex) within a 24-hour period to help treat a migraine or cluster headache. Make sure to take the second dose at least 1 hour after the first if you need more relief from your migraine or cluster headache. Speak with your prescriber about other treatment options to help if you still have symptoms after you've already taken 2 doses of sumatriptan injection (Imitrex) in a day. Also discuss with your prescriber about your options if you've already taken any migraine or headache medication for a total of 9 days in a month and you need more relief.
Multiple studies show that the majority of people who take sumatriptan injection (Imitrex) have improved migraine symptoms and pain relief after a single dose. Other studies also show that the majority of people who take sumatriptan injection (Imitrex) for cluster headaches report significant symptom relief within 2 hours of a dose. Talk to your prescriber if you're concerned with how well sumatriptan injection (Imitrex) works for you.
For migraine treatment, some people who took sumatriptan injection (Imitrex) started to feel pain relief within 10 minutes of the injection. Keep in mind that the study also found that it can sometimes take up to 2 hours to feel the maximum pain-relieving effects of the medication for migraine. For cluster headaches, some people felt pain relief within 5 to 15 minutes of taking sumatriptan injection (Imitrex).
No, sumatriptan injection (Imitrex) isn't a controlled substance. This medication doesn't have a risk of addiction or dependence.
It takes about 10 hours for sumatriptan injection (Imitrex) to leave your body after a single dose. This time frame is estimated based on the half-life of the medication, which is how long it takes for half the amount of medication to leave the body. Talk with your prescriber if you have questions about how long the medication stays in your body.
Yes, it's possible for sumatriptan injection (Imitrex) to make you sleepy, but it's not common. Only about 3% of people who took sumatriptan injection (Imitrex) reported feeling tired or fatigued as a side effect of the medication in clinical studies. Wait and see how sumatriptan injection (Imitrex) affects you before driving or performing activities that you need to be alert for.
Imitrex STATdose refers to the kit that contains two single-dose prefilled syringe cartridges of sumatriptan and an Imitrex STATdose pen. The prefilled syringe cartridges are also available by themselves (without the pen) for refills. You place the prefilled syringe cartridge into the Imitrex STATdose pen before you inject the medication. Most people just refer the medication as Imitrex to shorten the brand name. The Imitrex brand name is also available as tablets that are taken by mouth and a nasal spray.

Risks and warnings for Sumatriptan injection (Imitrex)
Sumatriptan injection (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 | People who are considered obese | High blood pressure | Smoking tobacco
Although rare, some people have reported serious heart problems, such as heart attack and heart rhythm problems, within a few hours after taking sumatriptan injection (Imitrex). In addition, this medication might make your blood pressure go up to dangerously high levels.
If you have a history of heart or blood circulation problems, talk to your primary care provider or cardiologist first to make sure sumatriptan injection (Imitrex) is as safe for you as possible. And make sure to periodically check your blood pressure while you're taking sumatriptan injection (Imitrex). Let your healthcare team 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 injection (Imitrex) have had life-threatening strokes or bleeding in the brain. For this reason, you won't be able to take this medication if you've had a stroke in the past. Let your primary care provider or neurologist know about your medical history.
Symptoms of stroke or other brain injuries include sudden weakness on one side of the body, severe 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. Stop taking sumatriptan injection (Imitrex) and get medical help as soon as possible if you notice symptoms of a stroke, especially if you haven't had a migraine or cluster headache before.
Extreme narrowing of blood vessels
Sumatriptan injection (Imitrex) can cause extreme narrowing of your blood vessels in different parts of your body. Depending on the location, this can lead to serious stomach problems (e.g., stomach pain, bloody diarrhea), vision problems, and changes in sensation in your hands and feet. Sometimes, it can cause symptoms similar to Raynaud's phenomenon, which can look like color changes in your hands and feet (can turn pale or more reddish depending on how much blood is flowing through). Don't take any more sumatriptan injection (Imitrex) until you see a member of your healthcare team if you notice these symptoms after you take the medication.
Worsened headaches if sumatriptan injection (Imitrex) is taken too often
Taking more than the recommended dose of migraine medications, including sumatriptan injection (Imitrex), or taking them too often can cause them to not work as well. This can lead to more migraine-like headaches or more migraine attacks. Let your primary care provider or neurologist know if you're taking multiple migraine medications and if you need to take them for more than 9 days per month. Your primary care provider or neurologist can talk with you about better options to help with migraines.
Serotonin syndrome
- Risk factors: Taking other medications that raise serotonin levels
Some people who take sumatriptan injection (Imitrex) have developed a rare, but potentially life-threatening condition called serotonin syndrome. This condition happens when there's too much serotonin in the brain.
Let your primary care provider or neurologist know about all the medications you take before you start sumatriptan injection (Imitrex), as well as any medications you plan to take. Your risk for serotonin syndrome can be higher if you take sumatriptan injection (Imitrex) with other medications that can raise your serotonin levels, such as certain antidepressants, mental health medications, and migraine medications.
Get medical help right away if you have any symptoms of serotonin syndrome, such as fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion.
Seizures
- Risk factors: History of seizures
Although rarely reported, some people have had a seizure after they took sumatriptan injection (Imitrex). Tell your prescriber if you have a history of seizures or if you have any health conditions that make you more prone to having seizures.
Severe allergic reaction
- Risk factors: Latex allergy
Rarely, sumatriptan injection (Imitrex) can cause life-threatening allergic reactions. Get medical help right away if you have hives, swelling in your face or throat, or trouble breathing.
Let your healthcare team know if you have an allergy to latex. The needle shield of the prefilled syringes contain latex, so people who have a latex allergy might have an allergic reaction if they use the prefilled syringes of sumatriptan injection (Imitrex).
