1. What Imigran is and what it is used for

Each Imigran 20 mg nasal spray contains a single dose of sumatriptan, which belongs to a group of medicines known as triptans (also known as 5-HT1 receptor agonists).

Imigran 20 mg is used to treat migraine headache.

The symptoms of migraine may be caused by a temporary dilation of blood vessels in the head. Imigran 20 mg is believed to reduce this dilation of blood vessels. This, in turn, helps relieve headache pain and other symptoms of a migraine attack, such as nausea or vomiting and sensitivity to light and sound.

2. What you need to know before using Imigran

Do not use Imigran 20 mg

• if you are allergic to sumatriptan or any of the other ingredients of this medicine (listed in section 6)
• if you have heart problems such as narrowing of the arteries (ischaemic heart disease) or chest pain (angina), or have had a heart attack
• if you have circulation problems in your legs causing pain, such as cramps when walking (peripheral vascular disease)
• if you have had a stroke or a mini-stroke (also called transient ischaemic attack or TIA)
• if you have high blood pressure. You may use Imigran 20 mg if your blood pressure is slightly elevated and is being treated
• if you have severe liver disease
• with other migraine medicines, including those containing ergotamine, or similar medicines such as methysergide, or any triptans/5-HT1 receptor agonists (medicines also used to treat migraine)
• with antidepressants known as MAOIs (monoamine oxidase inhibitors), or if you have taken these medicines within the last 2 weeks.

If any of these apply to you:

?Tell your doctor and do not use Imigran 20 mg.

Take special care with Imigran 20 mg

Talk to your doctor or pharmacist before starting to use Imigran 20 mg.

If you have any additional risk factors

• if you smoke heavily or are using nicotine replacement therapy, and especially
• if you are a man over 40 years of age, or
• if you are a woman who has entered menopause.

Very rarely, people have developed serious heart problems after using Imigran 20 mg, even though they showed no prior signs of heart disease. If any of the above apply to you, this may mean you have an increased risk of developing heart disease, so:

?Tell your doctor to check your heart function before being prescribed Imigran 20 mg.

If you have a history of seizures

Or if you have other conditions that may increase the likelihood of seizures – for example, head injury or alcoholism.

?Tell your doctor so you can be monitored more closely.

If you have liver or kidney disease

?Tell your doctor so you can be monitored more closely.

If you are allergic to antibiotics known as sulfonamides

If so, you may also be allergic to Imigran 20 mg. If you know you are allergic to antibiotics but are unsure whether they are sulfonamides:

?Tell your doctor or pharmacist before using Imigran 20 mg.

If you are taking antidepressants known as SSRIs (Selective Serotonin Reuptake Inhibitors) or SNRIs (Serotonin and Noradrenaline Reuptake Inhibitors)

?Tell your doctor or pharmacist before using Imigran 20 mg. See also, Other medicines and Imigran 20 mg.

If you use Imigran 20 mg frequently

Using Imigran 20 mg too often may worsen your headaches.

?Tell your doctor if this happens to you. Your doctor may advise you to stop using Imigran 20 mg.

If you experience chest pain or tightness after using Imigran 20 mg

These effects may intensify but usually pass quickly. If they do not pass quickly or become more severe:

?Get medical help immediately. See section 4 of this leaflet for more information about these possible side effects.

Other medicines and Imigran 20 mg

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicine. This includes any herbal remedies or medicines purchased without a prescription.

Some medicines should not be taken with Imigran 20 mg, and others may cause adverse effects when taken with Imigran 20 mg. Tell your doctor if you are taking other medicines, such as:

• Ergotamine, also used to treat migraine, or similar medicines such as methysergide (see section 2 Do not use Imigran 20 mg). Do not use Imigran 20 mg at the same time as these medicines. Stop taking these medicines at least 24 hours before using Imigran 20 mg. Do not take any other medicine containing ergotamine or ergotamine-like compounds until at least 6 hours after using Imigran 20 mg.
• Other triptans/5-HT1 receptor agonists (such as naratriptan, rizatriptan, zolmitriptan), also used to treat migraine (see section 2 Do not use Imigran 20 mg). Do not use Imigran 20 mg at the same time as these medicines. Stop taking these medicines at least 24 hours before using Imigran 20 mg. Do not take another triptan/5-HT1 receptor agonist within at least 24 hours after using Imigran 20 mg.
• SSRIs (Selective Serotonin Reuptake Inhibitors) or SNRIs (Serotonin and Noradrenaline Reuptake Inhibitors) used to treat depression. Using Imigran 20 mg with these medicines may cause serotonin syndrome (a group of symptoms that may include restlessness, confusion, sweating, hallucinations, increased reflexes, muscle spasms, shivering, increased heart rate, and agitation). Inform your doctor immediately if you experience these symptoms.
• MAOIs (monoamine oxidase inhibitors) used to treat depression. Do not use Imigran 20 mg if you have taken these medicines within the last 2 weeks.
• St. John’s Wort (Hypericum perforatum). You are more likely to experience adverse effects if you take herbal remedies containing St. John’s Wort while using Imigran 20 mg.

Pregnancy and breastfeeding

Tell your doctor or pharmacist before using any medicine.

• If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine. There is limited information on the safety of Imigran 20 mg in pregnant women, although so far there is no evidence that it increases the risk of birth defects. Your doctor will assess with you whether or not you should use Imigran 20 mg during pregnancy.
• You must not breastfeed your baby for 12 hours after taking Imigran 20 mg. If you express breast milk during this time, discard the milk and do not give it to your baby.

Some women have reported breast and/or nipple pain after using sumatriptan. This pain is usually temporary and resolves within 3 to 12 hours.

Driving and using machines

Migraine symptoms or the medicine may cause drowsiness. If this occurs, do not drive or operate machinery.

3. How to use Imigran

Use Imigran 20 mg only after your migraine headache has started.

Do not use Imigran 20 mg to prevent a migraine attack.

Follow step by step the guide for Imigran 20 mg

Do not open the blister until the moment you are going to use the spray. Each spray is sealed in a blister to keep it safe and clean. If you carry a spray without its blister, or in an opened blister, it may not work properly when you need it.

Each spray contains only one dose of Imigran 20 mg.

Do not press the plunger too early or you will lose the dose.

Imigran 20 mg consists of three parts:

How to use the nasal spray

1. Remove the nasal spray from the blister pack (blister) only immediately before use.
2. Adopt a comfortable position, preferably sitting down.
3. If you feel your nose is blocked or you have a cold**, blow your nose.**
4. Hold the nasal spray gently with your fingers and thumb as shown in Figure A.

Do not press the blue plunger yet.

1. Block one nostril by firmly pressing a finger against one side of your nose. It does not matter which nostril you choose.

1. Insert the nasal spray applicator into the other nostril, as far as comfortable – about 1 cm or half an inch (Figure B).

Breathe out gently through your mouth.

Keep your head upright and your mouth closed.

1. Begin to inhale gently through your nose.

While inhaling:

Firmly press the blue plunger with your thumb.

The plunger may feel slightly stiff and you may hear a click. Continue to inhale while pressing (Figure C).

1. Remove the nasal spray and take your finger off the side of your nose.

Keep your head upright for 10–20 seconds, breathing in gently through your nose and breathing out through your mouth. This helps the medicine stay in your nose.

You may notice your nose feels moist inside and detect a slight characteristic taste after using the nasal spray – this is normal and will pass quickly.

1. Your nasal spray is now empty. Dispose of it safely and hygienically.
