Uses of This Medicine:

Sumatriptan injection is used to treat acute migraine attacks and cluster headaches in adults. It does not prevent migraine attacks nor treat certain types of migraine headaches (e.g., hemiplegic or basilar type).

Many people find that their headaches go away completely after they use 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 good that it can do.

This medicine is available only with your doctor's prescription.

Before Using This Medicine:

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies—

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Children—

Appropriate studies have not been performed on the relationship of age to the effects of sumatriptan injection in the pediatric population. Safety and efficacy have not been established.

Older adults—

Use of sumatriptan injection is not recommended in elderly patients with kidney problems, heart or blood vessel disease, or high blood pressure, and should not be used by elderly patients with liver problems.

Pregnancy—

Breast-feeding—

Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.

Other medicines—

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Before deciding whether you should use this medicine, your doctor may need to do some tests to make sure that you do not have any of these conditions.

Proper Use of This Medicine:

Do not use this medicine for a migraine or cluster headache that is different from your usual headaches. Instead, check with your doctor.

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 using 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 use more than two doses in 24 hours.

This medicine is given as a shot under your skin (usually on the abdomen or stomach, thighs, or upper arms). Sumatriptan injection may sometimes be given at home to patients who do not need to be in a hospital or clinic. If you are using this medicine at home, your doctor or nurse will teach you how to prepare and inject the medicine. Be sure that you understand how to use the medicine.

If you use this medicine at home, you will be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas. This will help prevent skin problems.

This medicine is available in 3 forms. You may use a single dose vial, prefilled syringe, or a prefilled autoinjector.

After you have finished injecting the medicine, be sure to follow the precautions in the patient directions about safely discarding the empty cartridge and the needle. Always return the empty cartridge and needle to their container before discarding them. Do not throw away the autoinjector unit, because refills are available.

This medicine comes with a patient information leaflet. Read and follow the instructions carefully. Ask your doctor if you have any questions.

Dosing—

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.

• For injection dosage form:
  • For migraine or cluster headaches:
    • Adults—One 6-milligrams (mg) injected under the skin. One more 6-mg dose may be injected, if necessary, if the migraine comes back after being relieved. However, the second injection should not be given any sooner than 1 hour after the first one. Do not use more than two 6-mg injections in a 24-hour period (one day). However, some people may be directed to use no more than two 6-mg doses in a 48-hour period (two days).
    • Children—Use and dose must be determined by your doctor.

Storage—

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.

Throw away used syringes or autoinjectors in a hard, closed container that the needles cannot poke through. Keep this container away from children and pets.

Precautions While Using This Medicine:

Check with your doctor if you have used this medicine and have not had good relief. Also, check with your doctor if your migraine or cluster headaches are worse, or if they are occurring more often, than before you started receiving this medicine.

Make sure your doctor knows if you are pregnant. Your doctor may want you to join a pregnancy registry for patients using this medicine.

This medicine may increase your risk of having a heart attack or stroke. This is more likely to occur if you already have a heart disease, if you smoke, if you are over 40, or if you have gone through menopause. People who use this medicine for a long time might also have a higher risk.

You should not receive this medicine if you have used an MAO inhibitor (MAOI) such as isocarboxacid (Marplan®), phenelzine (Nardil®), selegiline (Eldepryl®), or tranylcypromine (Parnate®) within the past two weeks. Do not use this medicine if you have taken other migraine medicines (e.g., almotriptan, frovatriptan, naratriptan, rizatriptan, zolmitriptan, Axert™, Frova®, Amerge®, Maxalt®, or Zomig®) or an ergotamine medicine (e.g., methysergide, D.H.E. 45®, or Migranal®) within the past 24 hours.

Make sure your doctor knows about all the other medicines you are using. Sumatriptan may cause a serious condition called serotonin syndrome when used with some medicines. This especially includes medicines used to treat depression, such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, olanzapine, paroxetine, sertraline, venlafaxine, Celexa®, Cymbalta®, Effexor®, Lexapro®, Luvox®, Paxil®, Prozac®, Sarafem®, Symbyax®, or Zoloft®. Check with your doctor first before taking any other medicines.

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 doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).

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

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.

This medicine may cause some people to become dizzy, drowsy, or less alert than they are normally. If any of these side effects occur, do not drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert while you are using this medicine.

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.
