1. What Imigran is and what it is used for
Each Imigran nasal spray contains a single dose of sumatriptan, which belongs to a group of
medicines called triptans (also known as 5-HT1 receptor agonists).
Imigran nasal spray is used to treat migraine headache.
Migraine symptoms may be caused by the temporary widening of blood vessels in the head. Imigran
nasal spray is believed to reduce the widening of these blood vessels. This in turn helps to take away
the headache and relieve other symptoms of a migraine attack, such as feeling or being sick (nausea or
vomiting) and sensitivity to light and sound.
2. Before you use Imigran Nasal Spray
Don’t use Imigran:
• If you’re allergic to sumatriptan, or any of the other ingredients (listed in Section 6).
• If you have a heart problem such as narrowing of the arteries (Ischaemic heart disease) or chest
pains (angina), or have already had a heart attack.
• If you have circulation problems in your legs that cause cramp-like pains when you walk
(peripheral vascular disease).
• If you have had a stroke or a mini-stroke (also called a transient ischaemic attack or TIA).
• If you have high blood pressure. You may be able to use Imigran if your high blood pressure is
mild and is being treated.
• If you have serious liver disease.
• With other migraine medicines, including those which contain ergotamine, or similar medicines
such as methysergide or any triptan/5-HT1 receptor agonist (medicines which are also used for
• With anti-depressants called MAOIs (monoamine oxidase inhibitors), or if you have taken these
medicines in the last 2 weeks.
If any of these apply to you:
� Tell your doctor, and don’t use Imigran nasal spray.
Take special care with Imigran
Your doctor needs to know certain information before you use Imigran:
If you have any extra risk factors
• If you are a heavy smoker, or are using nicotine replacement therapy, and especially
• If you are a man aged over 40, or
• If you are a woman who has been through the menopause.
In very rare cases, people have developed serious heart conditions after using Imigran, even though
they had no signs of heart disease before. If any of the points above applies to you it could mean you
have a greater risk of developing heart disease - so:
� Tell your doctor so that your heart function can be checked before Imigran is prescribed for you.
If you have a history of fits (seizures)
Or if you have other conditions which might make it more likely that you’ll have a fit – for example, a
head injury or alcoholism:
� Tell your doctor so that you can be supervised more closely.
If you have liver or kidney disease
� Tell your doctor so that you can be supervised more closely.
If you are allergic to antibiotics called sulphonamides
If so, you may also be allergic to Imigran. If you know you are allergic to an antibiotic but you are not
sure whether it is a sulphonamide:
�Tell your doctor or pharmacist before using Imigran.
If you are taking anti-depressants called SSRIs
(Selective Serotonin Reuptake Inhibitors) or SNRIs(Serotonin Noradrenaline Reuptake Inhibitors)
� Tell your doctor or pharmacist before you use Imigran.Also see Other medicines and Imigran,
If you use Imigran frequently
Using Imigran too often may make your headaches worse.
�Tell your doctor if this applies to you. He or she may recommend you stop using Imigran.

These effects may be intense but they usually pass quickly. If they don’t pass quickly, or they become
� Get medical help immediately. Section 4 of this leaflet has more information about these possible
Other medicines and Imigran
Tell your doctor or pharmacist if you’re taking, have recently taken or might take any other
medicines. This includes any herbal products or medicines you’ve bought without a prescription.
Some medicines must not be taken with Imigran and others may cause adverse effects if they’re taken
with Imigran. You must tell your doctor if you are taking:
• ergotamine also used to treat migraine, or similar medicines such as methysergide (see Section
2). Don’t use Imigran at the same time as these medicines. Stop taking these medicines at least 24
hours before using Imigran. Don’t take any medicines which contain ergotamine or compounds
similar to ergotamine again for at least 6 hours after using Imigran.
• other triptans/5-HT1 receptor agonists (such as naratriptan, rizatriptan, zolmitriptan), also used
to treat migraine, (see Section 2). Don’t use Imigran at the same time as these medicines. Stop
taking these medicines at least 24 hours before using Imigran. Don’t take another triptan/5-HT1
receptor agonist again for at least 24 hours after using Imigran.
• SSRIs (Selective Serotonin Reuptake Inhibitors) or SNRIs (Serotonin Noradrenaline Reuptake
Inhibitors) used to treat depression. Using Imigran with these medicines can cause serotonin
syndrome (a collection of symptoms which can include restlessness, confusion, sweating,
hallucinations, increased reflexes, muscle spasms, shivering, increased heartbeat and shaking).
Tell your doctor immediately if you are affected in this way.
• MAOIs (monoamine oxidase inhibitors) used to treat depression. Don’t use Imigran if you have
taken these in the last 2 weeks.
• St John’s Wort (Hypericum perforatum). Taking herbal remedies that contain St John’s Wort while
you are using Imigran may make side effects more likely.
Pregnancy and breast-feeding
• If you are pregnant, think you may be pregnant or are planning to have a baby, ask your
doctor for advice before taking this medicine. There is only limited information about the safety
of Imigran for pregnant women, though up till now there is no evidence of any increased risk of birth
defects. Your doctor will discuss with you whether or not you should use Imigran while you are
• Don’t breast-feed your baby for 12 hours after using Imigran. If you express any breast milk
during this time, discard the milk and don’t give it to your baby.
Driving and using machines
Either the symptoms of migraine or your medicine may make you drowsy. If you are affected, don’t
drive or operate machinery.
