Sumatriptan is used to treat acute migraines in adults. It is not used to prevent migraines and is not used for cluster headaches. Sumatriptan works in the brain to relieve migraine pain. It belongs to a group of medicines called triptans.

Many people find that their headaches go away completely after taking sumatriptan. Other people find that their headaches are much less painful and that they can return to their normal activities, even if their headaches are not completely gone. Sumatriptan often relieves other symptoms that occur along with a migraine, such as nausea, vomiting, sensitivity to light, and sensitivity to sound.

Sumatriptan is not a common pain reliever. It will not relieve pain other than migraines. This medicine is usually used for people whose headaches are not relieved by acetaminophen, aspirin or other pain relievers.

Sumatriptan has caused serious side effects in some people, especially those with heart or blood vessel disease. Be sure to discuss with your doctor the risks of using this medication, as well as any benefits it may have.

This medicine is only available with a prescription.

This product is available in the following dosage forms:

  • Board

Do not use this medication for headaches other than your usual migraines. Talk to your doctor about what to do for regular headaches.

To relieve your migraine as quickly as possible, use this medication as soon as the headache starts. Even if you get warning signs of an upcoming migraine (an aura), you should wait until the headache starts before using sumatriptan.

Ask your doctor ahead of time about any other medications you can take if sumatriptan doesn't work. After using the other medicine, consult your doctor as soon as possible. Headaches that are not relieved by sumatriptan are sometimes caused by conditions that require other treatment.

It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and decide if you should continue to use it.

Check with your doctor if you used this medication and it didn't work. Also, check with your doctor if your migraines get worse or occur more frequently since you started using this medication.

You should not use this medication if you have used an MAOI inhibitor (MAOI) such as phenelzine (Nardil®) or tranylcypromine (Parnate®) in the last 2 weeks. Do not use this medication if you have taken other triptan migraine medications or ergot-type medications in the past 24 hours. Some examples of triptan medications are almotriptan (Axert®), eletriptan (Relpax®), naratriptan (Amerge®), or zolmitriptan (Zomig®). Some examples of ergot-type medications are dihydroergotamine (D.H.E. 45®, Migranal®), ergotamine (Bellergal®, Cafergot®, Ergomar®, Wigraine®) or methysergide (Sansert®).

This medication can cause problems if you have heart disease. If your doctor thinks you may have a problem with this medication, he may want you to have your first dose in the office or clinic.

This medication may increase your risk of having an abnormal heart rhythm, heart attack, angina, or stroke. This is more likely to happen if you or a family member already has heart disease, if you have diabetes, high blood pressure, high cholesterol, or if you smoke. Call your doctor right away if you have any symptoms of a heart problem, such as chest pain or discomfort, irregular heartbeat, nausea or vomiting, pain or discomfort in your shoulders, arms, jaw, back, or neck, trouble breathing, or sweating. Call your doctor right away if you have any symptoms of a stroke, such as confusion, slurred speech, double vision, headaches, inability to move your arms, legs, or facial muscles, inability to speak, or slow speech.

Consult your doctor immediately if you experience chest discomfort, jaw tightness, or neck tightness after using this medication. Also, tell your doctor if you have sudden or severe abdominal or stomach pain or bloody diarrhea after using this medication.

See your doctor immediately if you experience blurred vision, difficulty reading, or any other changes in vision during or after treatment. An ophthalmologist (ophthalmologist) may need to check your eyes.

Using sumatriptan alone or in combination with other migraine medications for 10 or more days a month may make your headache worse. You can keep a headache diary to record the frequency of your headaches and drug use.

Be sure to tell your doctor about all other medications you are using. Sumatriptan can cause a serious condition called serotonin syndrome when taken with some medications. This especially includes medications used to treat depression such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine, Celexa®, Cymbalta®, Effexor®, Lexapro®, Luvox®, Paxil®, Prozac®, Sarafem® , Symbyax® or Zoloft®. See your doctor immediately if you experience agitation, confusion, diarrhea, abnormal excited speech, fever, overactive reflexes, incoordination, restlessness, chills, sweating, tremors or tremors you can't control, or spasms. These could be symptoms of serotonin syndrome.

This medication can cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis requires immediate medical attention. The most serious signs of this reaction are very rapid or irregular breathing, shortness of breath, wheezing, or fainting. Other signs may include changes in facial skin color, a very fast but irregular heartbeat or pulse, hive-like bumps on the skin, and puffiness or puffiness of the eyelids or around the eyes. If these effects occur, seek emergency help immediately.

Drinking alcohol can make headaches worse or cause new headaches. People suffering from severe headaches should probably avoid alcoholic beverages, especially during a headache.

Some people feel dizzy or drowsy during or after a migraine, or use sumatriptan for migraine relief. While you feel dizzy or drowsy, do not drive, use machinery or do anything that could be dangerous if you are dizzy or not alert.
