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.

Check with your doctor if you used this medicine and it did not work. Also, check with your doctor if your migraine headaches are worse or if they are occurring more often since you started using this medicine.

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

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 abnormal heart rhythm, heart attack, angina, or stroke. This is more likely to occur 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, 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.

Check with your doctor right away if you have chest discomfort, jaw or neck tightness after using this medicine. Also, tell your doctor if you have sudden or severe abdominal or stomach pain or bloody diarrhea after using this medicine.

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).

Using sumatriptan alone or in combination with other migraine medicines for 10 or more days per month may lead to worsening of headache. You may keep a headache diary to record your headache frequency and drug use.

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.

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.

Sumatriptan is used to treat migraines. It helps to relieve headache, pain, and other migraine symptoms (including nausea, vomiting, sensitivity to light/sound). Prompt treatment helps you return to your normal routine and may decrease your need for other pain medications. Sumatriptan belongs to a class of drugs known as triptans. It affects a certain natural substance (serotonin) that causes narrowing of blood vessels in the brain. It may also relieve pain by affecting certain nerves in the brain.

Sumatriptan does not prevent future migraines or lessen how often you get migraine attacks.

How to use Imitrex

Read the Patient Information Leaflet if available from your pharmacist before you start taking sumatriptan and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, at the first sign of a migraine. The dosage is based on your medical condition and response to treatment. If there is no improvement in your symptoms, do not take more doses of this medication before talking to your doctor. If your symptoms are only partly relieved, or if your headache comes back, you may take another dose at least two hours after the first dose. Do not take more than 200 milligrams in a 24-hour period.

This medication may also be used as a backup for sumatriptan injection. If your symptoms are only partly relieved or your headache comes back, you may take a dose of sumatriptan by mouth at least two hours after the injection, up to a maximum of 100 milligrams in a 24-hour period.

If you have a higher risk for heart problems (see Precautions), your doctor may perform a heart exam before you start taking sumatriptan. He/she may also direct you to take your first dose of this medication in the office/clinic to monitor for serious side effects (such as chest pain). Talk to your doctor for details.

If you are using drugs for migraine attacks on 10 or more days each month, the drugs may actually make your headaches worse (medication overuse headache). Do not use medications more often or for longer than directed. Tell your doctor if you need to use this medication more often, or if the medication is not working as well, or if your headaches get worse.

Flushing, feelings of tingling/numbness/prickling/heat, tiredness, weakness, drowsiness, or dizziness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: blue fingers/toes/nails, cold hands/feet, hearing changes, mental/mood changes.

Sumatriptan can commonly cause chest/jaw/neck tightness, pain, or pressure that is usually not serious. However, these side effects are like symptoms of a heart attack, which may include chest/jaw/left arm pain, shortness of breath, or unusual sweating. Get medical help right away if these or other seriousfast/irregular heartbeat, fainting, severe stomach/abdominal pain, bloody diarrhea, seizure, signs of a stroke (such as weakness on one side of the body, trouble speaking, sudden vision changes, confusion).

This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
