Brand name: Imigran
- Imitrex
Pronounced: IM-i-kran
Generic name: Sumatriptan succinate
Why is Imigran prescribed?
Imigran is prescribed for the treatment of a migraine attack with
or without the presence of an aura (visual disturbances, usually sensations
of halos or flickering lights, which precede an attack). The injectable
form is also used to relieve cluster headache attacks. (Cluster headaches
come on in waves, then disappear for long periods of time. They are
limited to one side of the head, and occur mainly in men.)
Imigran cuts headaches short. It will not reduce the number of attacks
you experience.
Most important fact about Imigran
Imigran should be used only to treat an acute, classic migraine attack
or a cluster headache. It should not be used for certain unusual types
of migraine.
How should you take Imigran without a prescriptions?
Imigran should be taken as soon as your symptoms appear, but may be
used at any time during an attack. It is available in three forms:
injection, tablets, and nasal spray.
Imigran injection is administered just below the skin with an autoinjector
(self-injection device). Choose a site where the skin is thick enough
to take the full length of the needle (1/4 inch). Avoid injecting Imigran
into a muscle or a vein. Your doctor should instruct you on how to
use the autoinjector and how to dispose of the empty syringes. You
should also read the instruction pamphlet that comes with Imigran.
You can take a second injection if your headache returns; however,
never take more than 2 injections within 24 hours, and be sure to wait
1 hour between doses.
Imigran tablets should be swallowed whole, with liquid. If you have
had no relief 2 hours after taking Imigran Tablets, you may take a
second dose of up to 100 milligrams, if your doctor advises it. If
the headache returns, you may take additional doses at intervals of
at least 2 hours. You should not take more than 300 milligrams in one
day. If your headache returns after you have had an Imigran Injection,
you may take single Imigran Tablets, at intervals of at least 2 hours,
up to a maximum of 200 milligrams in a day.
Imigran nasal spray is packaged in single-dose bottles containing
either 5 or 20 milligrams of the drug. The usual dosage is a single
spray in one nostril. If the headache returns, you may repeat the dose
once after 2 hours. Do not take more than 40 milligrams a day.
If you miss a dose...
Imigran is not for regular use. Take it only during an attack.
Storage instructions...
Store Imigran away from heat and light, at room temperature, in the
case provided. If your medication has expired (the expiration date
is printed on the treatment pack), throw it away as instructed, but
keep the autoinjector. If your doctor decides to stop your treatment,
do not keep any leftover medicine unless your doctor tells you to.
Throw away your medicine as instructed.
Imigran side effects
Side effects cannot be anticipated. If any develop or change in intensity,
inform your doctor as soon as possible. Only your doctor can determine
if it is safe for you to continue taking Imigran.

Burning sensation, dizziness or vertigo, feeling of heaviness, feeling of tightness,
flushing, mouth and tongue discomfort, muscle weakness, nausea (nasal spray),
neck pain and stiffness, numbness, pressure sensation, redness at the site
of injection, sinus or nasal discomfort (nasal spray), sore throat, tingling,
unusual taste (nasal spray), vomiting (nasal spray), warm/cold sensation
In addition to the above side effects, people taking Imigran for cluster

Why should Imigran not be prescribed?
Imigran should not be used for the hemiplegic or basilar forms of
migraine. You must also avoid Imigran if it gives you an allergic reaction.
In addition, the drug should not be prescribed if you have certain
types of heart or blood vessel disease, including angina (crushing
chest pain) or a history of heart attack, stroke, mini-strokes, or
other circulatory problems. It should not be used if you have severe
liver disease or uncontrolled high blood pressure. It must not be used
within 24 hours of taking an ergotamine-based migraine remedy (such
as D.H.E. 45 Injection or Sansert) or any drug in the same class as
Imigran (such as Amerge, Maxalt, or Zomig). And it must not be used
for 2 weeks after taking an MAO inhibitor drug such as the antidepressants
Nardil and Parnate.
Special warnings about Imigran
Although the danger is minimal, Imigran has triggered serious heart
problems in people with heart disease. For that reason, the doctor
may want you to take your first dose of Imigran in the office, where
you can be closely watched for ill effects.
Be sure to tell the doctor if you have any conditions that increase
your risk of heart disease, such as high blood pressure, high cholesterol,
or diabetes. Also let him know if you smoke, have heart disease in
the family, or have gone through menopause. Patients at risk of heart
disease should have periodic cardiac evaluations as long as they continue
using Imigran. If you develop pain or tightness in the chest, throat,
or jaw after taking a dose, consult your doctor before taking any more.
If you develop severe chest pain, call the doctor immediately. Also
seek immediate attention if you suffer sudden, severe abdominal pain
after a dose of Imigran. It could signal a blood vessel problem.
Be careful not to inject Imigran into a vein. This can cause a serious
heart irregularity.
If your fingers turn pale, then blue, after a dose of Imigran, you
may have a circulatory problem such as hardening of the arteries. Be
sure to let your doctor know.
This medication should not be used for other types of migraine headache.
If the first dose does not relieve your symptoms, your doctor will
re-evaluate you; you may not have migraine or cluster headache.
If your headache does not feel like any you have been experiencing,
do not take Imigran.
Use Imigran cautiously if you have liver or kidney disease. Also,
if you have any trouble with your eyes, tell your doctor.
Imigran is not recommended for adults over 65. It
has not been tested in children.
Although very rare, severe and even fatal allergic reactions have
occurred in people taking Imigran. Such reactions are more likely in
people who have several allergies.
In rare cases, people have suffered seizures after taking Imigran.
Use the drug with caution if you have epilepsy or any condition that
increases your risk of having a seizure.
Possible food and drug interactions when taking Imigran
If Imigran is taken with certain other drugs, the effects of either
may be increased, decreased, or altered. It is important to check with
your doctor before combining Imigran with the following:
Drugs classified as MAO inhibitors, including the antidepressants
Nardil and Parnate
Ergot-containing drugs such as Cafergot and Ergostat
Fluoxetine (Prozac)
Fluvoxamine (Luvox)
Paroxetine (Paxil)
Sertraline (Zoloft)
Special information if you are pregnant or breastfeeding
The effects of Imigran during pregnancy have not been adequately studied.
If you are pregnant or plan to become pregnant, inform your doctor
immediately. Imigran does appear in breast milk and could affect a
nursing infant. If Imigran is essential to your health, your doctor
may advise you to discontinue breastfeeding until your treatment with
Imigran is finished.
