|1. What Imigran is and what it is used foi
Each Imigran pre-filled cartridge syringe contains a single dose of sumatriptan, which belongs to a group of medicines called triptans (also known as 5-HTi receptor agonists).
Imigran is used to treat migraine headache and a rare condition called cluster headache.
Migraine and cluster headache symptoms may be caused by the temporary widening of blood vessels in the head.
Imigran is believed to reduce the widening of these blood vessels. This in turn helps to take away the headache and relieve other symptoms 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
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 maleate; or any triptan or 5-HTi agonist (such as naratriptan or zolmitriptan)
■ With any of the following anti-depressants:
■ MAOIs (monoamine oxidase inhibitors) or if you have taken an MAOI in the last 2 weeks
■ SSRIs (selective serotonin reuptake inhibitors) including citalopram, fluoxetine, fluvoxamine, paroxetine and sertraline

■ 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
If either of these apply to you:
^ Tell your doctor or pharmacist before using Imigran.

^ Get medical help immediately. Section 4 (below) 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). 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-HTf receptor agonists (such as naratriptan, rizatriptan, zolmitriptan), also used to treat migraine, (see section 2 Don't use Imigran). Don't use Imigran at the same time as these medicines. Stop taking these medicines at least 24 hours before using Imigran.

Tell your doctor immediately if you are affected in this way.
■ St John's Wort (Hypericum perforatum). Taking herbal remedies containing St John's Wort while using Imigran may make side effects more likely.

■ 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.

Your doctor will discuss with you whether or not you should use Imigran while you are pregnant

How to give an injection using the Imigran Pen
■ Read the leaflet fully and carefully before using the Imigran Pen
■ Each Imigran injection system comes complete with a Cartridge Pack which contains two cartridge syringes pre-filled with Imigran
■ Use the photo above to help you identify the different parts of the injection system
■ Do not load the Pen until you are ready to give the injection.
1 Swing open the Lid of the Carrycase.
3 Take out the Imigran Pen from the Carrycase. Check that the White Rod is not sticking out beyond the end of the Pen (see picture11). If it is sticking out, place the Pen back inside the Carrycase, push firmly and the Rod should click into place. The Pen is now ready for use.
4 Push the Imigran Pen firmly into the opened Cartridge Pack and gently screw it clockwise (about half a turn) until it will twist no further.
5 Keeping your finger away from the blue Release Button, pull the Imigran Pen out of the Cartridge Pack. You may have to pull quite hard to do this. A safety catch stops accidental injection before you are ready.
6 The loaded Pen is now ready for immediate use.
Do not try to put the loaded Pen back into the Carrycase until after you have used the injection, or the needle may be damaged and the Pen will not inject correctly.
7 Press the Pen with the long blue Nose End firmly against a clean area of skin - usually the outside of the thigh (as in picture) - so the grey part slides down to cover part of the blue nose.
This releases the safety catch.
8 Hold the Pen firmly and press the blue Release Button at the top of the Subject Pen. Count slowly to 10 keeping the Subject Pen very still and the Release Button depressed.
Do not take the Pen away from the skin too soon or some of the injection may be wasted.
Then lift the Pen away taking care not to touch the needle
Return the used cartridge syringe to the empty space in the Cartridge Pack straight away.
10 Pushing the Pen down into the Cartridge Pack as far as it will go, unscrew the Pen by twisting it anti-clockwise (about half a turn) until it comes away.
11 Withdraw the Subject Pen from the Cartridge Pack. Close the blue hinged lid over the used syringe.
12 Put the Subject Pen back into the Carrycase and push it down until it stays down. It will click into place. The Subject Pen is then ready for use next time.
13 Close the Lid of the Carrycase until you need to use the next cartridge syringe. When you have used both cartridges, remove and replace the Cartridge Pack. (See right.)
How to remove the used Cartridge Pack
1 When both syringes have been used, you can remove the Cartridge Pack.
3 Gently pull out the Cartridge Pack with the other hand.
4 Be careful to dispose of your empty Cartridge Packs safely. The Cartridge Pack will hold the used Subject cartridge syringes and needles until you can safely dispose of them. You should be able to do this at your doctor's surgery, so ask your doctor or practice nurse.
How to put a new Cartridge Pack into the Carrycase
Each Subject Pen comes complete with an Imigran Cartridge Pack which contains two prefilled cartridge syringes.
1 Swing open the Lid of the Carrycase, the Subject Pen is already in its place.
2 Push the Cartridge Pack into the Carrycase, pressing the blue buttons on either side so it slides in smoothly.
3 It does not matter which side of the Cartridge Pack is closest to the Subject Pen.
4 The Cartridge Pack is in the right position when the blue Locating Buttons show through the holes on either side of the Carrycase.
5 Close the Carrycase by swinging back the Lid and snapping it shut.
6 You can keep your Cartridge Pack safely in the Carrycase until you need to give yourself an injection.
7 Keep your Carrycase and any refill Cartridge Packs at a temperature below 30°C/86°F. If they are kept warmer than this for more than 24 hours it could spoil them.
