1 What is Alsuma?

Brand: Alsuma, Imitrex, Imitrex Stat Dose Refill, Sumavel Dosepro

Generic: Sumatriptan

Alsuma is used to treat acute migraine attacks and cluster headaches in adults. Sumatriptan works in the brain to relieve pain from migraine headaches. It belongs to a group of medications called Triptans.

Many patients find that their headaches go away completely after they use Sumatriptan. Other people find their headaches are much less painful and that they are able to go back to their normal activities, even if their headaches are not completely gone.

Alsuma often relieves other symptoms caused by migraines such as nausea, vomiting and light and sound sensitivities.

This medication is not an ordinary pain reliever. It will not relieve any kind of pain other than migraine headaches. This medication is normally used for people whose headaches are not relieved by acetaminophen, ibuprofen or other pain relievers.

Alsuma has caused serious side effects in some people, especially people who have heart or blood vessel disease. Be sure that you discuss the risks and benefits with your doctor.

This medication is only available with your doctor’s prescription. This medication is available in the following forms:

3 Proper Usage

To use Alsuma properly, you must follow all instructions given by your doctor. Do not use this medication for a migraine or a cluster headache that is different from your normal headaches.

To relieve your migraine as soon as possible, use this medication as soon as your headache pain begins. If you get warning signals of a migraine (auras), you should wait until the pain starts before using this medication.

Ask your doctor ahead of time about other medication you can use if Sumatriptan does not work. After using the other medication, inform your doctor immediately. Headaches that are not relieved by this medication may be caused by conditions that need other treatment.

If you feel better after a dose of this medication, but your headache comes back or gets worse after a while, wait at least 1 hour before taking another dose. Use this medication as directed by your doctor. Do not use more of this medication or more often than directed. Using too much of this medication can increase the chance of serious side effects. Do not use more than 2 doses in 24 hours.

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

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

This medication is available in 3 forms:

  • Single dose vial
  • Pre-filled syringe
  • Pre-filled autoinjector

Do not use this medication if it is dark-coloured or cloudy.

After you are done injecting the medication, follow the precautions in the patient directions and safely discard the empty cartridge and needle. Always return the empty cartridge and needle to their container before discarding them. Refills are available, so do not throw away the injector unit.

This medication comes with a patient information brochure. It is very important that you read this information. Ask your doctor if you have any questions.


Different patients will be given a different dose of this medication based on the strength of the medication. The number of doses you take each day, the time between doses and the length of time you take this medication depends on the reason you are taking this medication.

The following information only includes the average dose of this medication. If your dose is different, do not change it without first speaking to your doctor.

  • Adults - 4-6 mg injected under the skin (subcutaneous). If a headache comes back after being relieved, one more dose may be injected after 1 hour. Do not use more than 2 doses of 6 mg or 3 doses of 4 mg in a 24 hour period.

4 Precautions to Take

Before using Alsuma, there are some precautions you must take. It is very important that your doctor checks in with you often while you are receiving this medication to make sure that it is working properly.

Inform your doctor if you have used this medication and have not had relief. Inform your doctor if your migraine or cluster headaches are worse or if they occur more often than before you started using this medication.

You should not receive this medication if you have used a MAO inhibitor (MAOI) such as phenelzine or tranylcypromine within the past 2 weeks. Do not use this medication if you have used other triptan migraine medications. Some examples of triptan medications are almotriptan, eletriptan, naratriptan or zolmitriptan. Some examples of ergot-type medications are dihydroergotamine, ergotamine or methysergide.

This medication may increase your risk of having abnormal heart rhythm, heart attack, angina or stroke. This is more likely if you or a family member already has heart disease, if you have diabetes or hypertension (high blood pressure) or if you smoke.

Call your doctor immediately if you have any symptoms of a heart problem such as chest pain or discomfort, uneven heartbeat (arrhythmia), nausea or vomiting, pain or discomfort in the shoulders, arms jaw, back or neck, shortness of breath, severe abdominal pain or bloody diarrhea after using this medication.

Call your doctor immediately if you have any symptoms of a stroke, such as confusion, difficulty speaking, double vision, headaches, inability to move the arms, legs or facial muscles, inability to speak or slow speech.

Inform your doctor immediately if blurred vision, difficulty reading or another change of vision occurs during or after your treatment. Your doctor may want you to have your eyes checked by an ophthalmologist.

Using this medication alone or with another migraine medication for 10 or more days per month may lead to a worsening headache. You may need to keep a headache diary to record the headache frequency and drug use.

Be sure your doctor knows the other medications you are using. Sumatriptan may cause a serious condition called serotonin syndrome when used with some medications. This includes medications used to treat depression such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, olanzapine, paroxetine, sertralin and venlafaxine.

Inform your doctor immediately if you have agitation, confusion, diarrhea, abnormal excitement while talking, 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 medication may cause a serious type of allergic reaction called anaphylaxis, which is life-threatening and requires immediate emergency medical help.

Inform your doctor immediately if you have fast or irregular breathing, gasping for breath, wheezing, fainting (syncope), changes in the colour of the face, fast and irregular heartbeat, hive-like swelling on the skin or puffiness or swelling around the eyelids or eyes.

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

This medication may cause some people to become dizzy, drowsy or less alert than normal. This is more likely to happen when you begin taking this medication, or when you increase the dosage. Make sure you know how you react to this medication before driving, using machinery or doing anything else that could be dangerous if you are not alert.
