Other medicines and Imigran nasal spray

Your medicine is available using the names Imigran 20mg Nasal Spray / Sumatriptan 20mg Nasal
Spray but will be referred to as Imigran nasal spray throughout this leaflet.

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.

Read all of this leaflet carefully before you start taking this medicine because it
contains important information for you.





Some medicines must not be taken with Imigran nasal spray and others may cause adverse effects if
they’re taken with Imigran nasal spray. 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 nasal spray at the same time as these medicines. Stop taking these
medicines at least 24 hours before using Imigran nasal spray. Don’t take any medicines which
contain ergotamine or compounds similar to ergotamine again for at least 6 hours after using
Imigran nasal spray.

other triptans/5-HT1 receptor agonists (such as naratriptan, rizatriptan, zolmitriptan), also
used to treat migraine, (see Section 2). Don’t use Imigran nasal spray at the same time as these
medicines. Stop taking these medicines at least 24 hours before using Imigran nasal spray. Don’t
take another triptan/5-HT1 receptor agonist again for at least 24 hours after using Imigran nasal
spray.

SSRIs (Selective Serotonin Reuptake Inhibitors) or SNRIs (Serotonin Noradrenaline Reuptake
Inhibitors) used to treat depression. Using Imigran nasal spray 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 nasal spray 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 nasal spray may make side effects more likely.

Keep this leaflet. You may need to read it again.
If you have any further questions, ask your doctor or pharmacist.
This medicine has been prescribed for you only. Do not pass it on to others – it may harm them,

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 5-HT1 receptor agonists).

Pregnancy and breast-feeding

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. WHAT YOU NEED TO KNOW BEFORE YOU USE IMIGRAN NASAL
SPRAY

Driving and using machines

Don’t use Imigran nasal spray:









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 nasal spray 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 nasal
spray while you are pregnant.
Don’t breast-feed your baby for 12 hours after using Imigran nasal spray. If you express
any breast milk during this time, discard the milk and don’t give it to your baby.

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 nasal spray 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
treating migraine).
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:

pharmacist.

Step-by-step guide to using your Imigran nasal spray

Other common side effects include:

Don’t open a blister until you are ready to use a spray. Each spray is sealed in a blister to keep it
clean and safe. If you carry a spray without a blister, or in an open blister, it may not work properly
when you need it.
Each spray contains just one dose of Imigran nasal spray. Don’t press the plunger too soon or
you will lose the dose.
Imigran nasal spray has three parts:
The nozzle









Very rare side effects

The part that you put into your nostril.
The spray comes out of a tiny hole in the top.

(affect up to 1 in 10,000 people)

Liver function changes. If you have a blood test to check your liver function, tell your doctor or
nurse that you are using Imigran.

The finger-grip

Some patients may have the following side effects but it is not known how often
they occur

Hold this when you use the spray.

The blue plunger
Press this to spray the whole dose into your nostril in one go.
This only works once – don’t press the plunger until you have put
the nozzle into your nostril or you will lose the dose.

How to use the nasal spray
1.

Remove the nasal spray from the blister packaging just before
you want to use it.

2.

Get into a comfortable position. You may prefer to sit down.

3.

Blow your nose if it feels blocked, or if you have a cold.

4.

Hold the nasal spray gently with your fingers and thumb, as
shown in picture A.
Don’t press the blue plunger yet.

5.

Block one nostril by pressing a finger firmly on the side of
your nose. It doesn’t matter which nostril you choose.

6.

Put the nozzle of the nasal spray into the other nostril,
as far as feels comfortable - about 1 cm or 1/2 inch (picture
B). Breathe out gently through your mouth. Hold your
head upright and close your mouth.












7.

8.

Start to breathe in gently through your nose.
As you breathe in:
Press the blue plunger firmly with your thumb.
The plunger may feel a bit stiff and you may hear it click.
Keep breathing in while spraying (picture C).
Remove the spray and remove your finger from the
side of your nose. Keep your head upright for 10-20
seconds, breathing gently in through your nose and out
through your mouth. This helps the medicine stay in your
nose. Your nose may feel wet inside and you may notice a
slight taste after using the spray - this is normal and will
soon pass.

Your nasal spray is now empty. Throw it away safely and hygienically.
