Sumatriptan (Oral route)
Serotonin Receptor Agonist, 5-HT1
Uses of This Medicine:
Sumatriptan is used to treat acute migraine headaches in adults. It is not used to prevent migraine headaches and is not used for cluster headaches. Sumatriptan works in the brain to relieve the pain from migraine headaches. It belongs to the group of medicines called triptans.
Many people find that their headaches go away completely after they take sumatriptan. Other people find that their headaches are much less painful, and that they are able to go back to their normal activities even though their headaches are not completely gone. Sumatriptan often relieves other symptoms that occur together with a migraine headache, such as nausea, vomiting, sensitivity to light, and sensitivity to sound.
Sumatriptan is not an ordinary pain reliever. It will not relieve any kind of pain other than migraine headaches. 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 people who have heart or blood vessel disease. Be sure that you discuss with your doctor the risks of using this medicine as well as the benefits that it can have.
This medicine is available only with your doctor's prescription.

Other medical problems—
The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:
Proper Use of This Medicine:
Do not use this medicine for a headache that is different from your usual migraines. Talk to your doctor about what to do for regular headaches.
To relieve your migraine as soon as possible, use this medicine as soon as the headache pain begins. Even if you get warning signals of a coming migraine (an aura), you should wait until the headache pain starts before using sumatriptan. Using sumatriptan during the aura probably will not prevent the headache from occurring. However, even if you do not use sumatriptan until your migraine has been present for several hours, the medicine will still work.
Lying down in a quiet, dark room for a while after you use this medicine may help relieve your migraine.
If you feel much better after a dose of sumatriptan, but your headache comes back or gets worse after a while, wait at least 2 hours before taking another dose. However, use this medicine only as directed by your doctor. Do not use more of it, and do not use it more often, than directed. Using too much sumatriptan may increase the chance of side effects. Do not take more than 200 mg in 24 hours.
You may take the tablet with or without food.
Using this medicine for 10 or more days per month may make your headache worse (medication overuse headache). If your headache becomes worse, call your doctor. It is also important that you write down when you have migraine headaches and when you take this medicine.
This medicine comes with a patient information leaflet. Read and follow the instructions carefully. Ask your doctor if you have any questions.
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
Precautions While Using This Medicine:
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 to decide if you should continue to use it.
You should not use this medicine if you have used an MAO inhibitor (MAOI) such as isocarboxazid (Marplan®), phenelzine (Nardil®), selegiline (Eldepryl®), or tranylcypromine (Parnate®) within the past 2 weeks. Do not use this medicine if you have taken other migraine medicines (e.g., almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan/naproxen, zolmitriptan, Amerge®, Axert™, Frova®, Maxalt®, Relpax®, Treximet®, or Zomig®) or an ergotamine medicine (e.g., dihydroergotamine, methysergide, Cafergot®, D.H.E. 45®, Ergomar®, Migergot®, or Migranal®) within the past 24 hours.
Check with your doctor if you have used this medicine and your migraine did not go away, or if your migraine got worse or started occurring more often.
This medicine may cause problems if you have heart disease. If your doctor thinks you might have a problem with this medicine, he or she may want you to take your first dose in the doctor’s office or clinic.
This medicine may increase your risk of having a heart attack, angina, or stroke. This is more likely to occur if you have diabetes, high blood pressure, or high cholesterol, or if you already have a heart disease or a family history of heart disease, if you smoke, if you are male and over 40 years of age, or if you are female and have gone through menopause. Call your doctor right away if you have any symptoms of a heart problem, such as chest pain or discomfort, an uneven heartbeat, nausea or vomiting, pain or discomfort in the shoulders, arms, jaw, back, or neck, shortness of breath, or sweating. Call your doctor right away if you have any symptoms of a stroke, such as confusion, difficulty with speaking, double vision, headaches, an inability to move the arms, legs, or facial muscles, an inability to speak, or slow speech.
Make sure your doctor knows about all the other medicines you are using. Sumatriptan may cause a serious condition called serotonin syndrome when taken with some medicines. This especially includes medicines 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®. Check with your doctor right away if you have agitation, confusion, diarrhea, excitement while talking that is not normal, fever, overactive reflexes, poor coordination, restlessness, shivering, sweating, trembling or shaking that you cannot control, or twitching. These could be symptoms of serotonin syndrome.
This medicine may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis requires immediate medical attention. The most serious signs of this reaction are very fast or irregular breathing, gasping for breath, wheezing, or fainting. Other signs may include changes in color of the skin of the face, very fast but irregular heartbeat or pulse, hive-like swellings on the skin, and puffiness or swellings of the eyelids or around the eyes. If these effects occur, get emergency help at once.
Check with your doctor immediately if blurred vision, difficulty in reading, or any other change in vision occurs during or after your treatment. Your eyes may need to be checked by an ophthalmologist (eye doctor).
Drinking alcoholic beverages can make headaches worse or cause new headaches to occur. People who suffer from severe headaches should probably avoid alcoholic beverages, especially during a headache.
Some people feel dizzy or drowsy during or after a migraine, or using sumatriptan to relieve a migraine. As long as you are feeling dizzy or drowsy, do not drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
