1. What Imigran nasal spray 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 5HT1 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
2. What you need to know before you use Imigran nasal spray
Don’t use Imigran:
 If you’re allergic to sumatriptan, or any of the other ingredients of this
medicine (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/5HT1 receptor agonist (medicines which are also used for treating
 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
Talk to your doctor or pharmacist before using 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
Tell your doctor or pharmacist before using Imigran. Also see
Other medicines and Imigran, below.
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.
If you feel pain or tightness in your chest after you use Imigran
These effects may be intense but they usually pass quickly. If they don’t
pass quickly, or they become severe:
 Get medical help immediately. Section 4 of this leaflet has more
information about these possible side effects.
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 pregnant.
 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.
