Uses for Imitrex

Sumatriptan nasal powder and spray are used to treat acute migraine headaches with or without aura in adults. It is not used to prevent migraine headaches and is not used to treat 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 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 as well as the benefits of using this medicine.

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

Before using Imitrex

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.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of sumatriptan nasal powder and spray in the pediatric population. Use of Tosymra™ is not recommended in children. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of Tosymra™ in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving this medicine.

Use of Imitrex® and Onzetra™ are 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.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Proper use of Imitrex

Use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. Using too much sumatriptan may increase the chance of side effects.

This medicine is for use only in the nose. Do not get any of it into your eyes or on your skin. If it does get on these areas, rinse it off right away.

Do not use this medicine for a headache that is different from your usual migraines. 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.

Ask your doctor ahead of time about any other medicine you might take if sumatriptan does not work. After you take the other medicine, check with your doctor right away. Headaches that are not relieved by sumatriptan are sometimes caused by conditions that need other treatments.

If you feel much better after a dose of sumatriptan, but your headache comes back or gets worse after a while, you may use one additional dose of sumatriptan at least 1 hour (Tosymra™) or 2 hours (Imitrex® or Onzetra™) after the first dose. Do not use more than 3 doses in any 24-hour period.

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

To use the nasal powder:

• This medicine is given through the Xsail™ breath-powered delivery device.
• Remove the disposable nosepiece from its foil pouch, then remove the clear device cap from the reusable delivery device, and click the nosepiece into the device body. Use the nosepiece immediately after removing from the foil pouch.
• Fully press and release the white piercing button on the device body to pierce the capsule inside the nosepiece. Press it only once.
• Insert the nosepiece into the nostril so that it makes a tight seal. The device is then rotated and the mouthpiece inserted between the lips.
• Blow forcefully through the mouthpiece to deliver the medicine into the nasal cavity. Do not press the white button while blowing.
• Press the clear tab to remove the first nosepiece. Throw the used nosepiece in the trash can.
• Repeat the same steps using a second nosepiece into the other nostril to complete the recommended dose.

To use the nasal spray:

• Gently blow your nose to clear the nostrils before you use this medicine.
• Gently press one nostril to close it.
• Hold the device upright between your thumb and first 2 fingers. Insert half of the spray nozzle into the open nostril and angle outward.
• Tilt your head back slightly.
• Firmly press the plunger all the way up as you slowly breathe through your nose.
• Remove the device from your nostril. Keep your head upright and gently breathe in through your nose and breathe out through your mouth. Repeat this for 10 to 20 seconds. You may feel liquid in your nose or at the back of your throat.
• Do not look down as this may cause the medicine to drip from your nose.

Precautions while using Imitrex

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. Blood and urine tests may be needed to check for unwanted effects.

Do not use this medicine if you have taken other triptan or ergot-type migraine medicines within the past 24 hours. Some examples of triptan medicines are almotriptan (Axert®), eletriptan (Relpax®), frovatriptan (Frova®), naratriptan (Amerge®), rizatriptan (Maxalt®), sumatriptan/naproxen (Treximet®), or zolmitriptan, (Zomig®). Some examples of ergot-type medicines are dihydroergotamine (D.H.E. 45®, Migranal®), ergotamine (Bellergal®, Cafergot®, Ergomar®, Wigraine®), or methysergide (Sansert®). Also, do not use this medicine if you have taken a MAO-A inhibitor (eg, Nardil®, Parnate®) in the past 14 days.

This medicine may cause a serious type of allergic reaction called anaphylaxis, which can be life-threatening and requires immediate medical attention. The most serious signs of this reaction are very fast or irregular breathing, gasping for breath, or fainting. Other signs may include: changes in facial skin color, 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 side effects occur, get emergency help at once.

Check with your doctor if you have used this medicine and 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 an 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, 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.

Using sumatriptan alone or in combination with other migraine medicines for 10 or more days per month may lead to worsening of headaches. You may keep a headache diary to record the 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, olanzapine, 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.

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. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

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.
