1. WHAT NARATRIPTAN IS AND WHAT IT IS USED FOR
Naratriptan contains naratriptan (hydrochloride), which belongs to a group of medicines called triptans (also known as 5-HTi receptor agonists).
Naratriptan tablets are used to treat migraine with or without aura.
Migraine symptoms may be caused by the temporary widening of blood vessels in the head. Naratriptan tablets are 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 TAKE NARATRIPTAN
Not for the elderly or children under 18
Naratriptan is not recommended for people aged over 65, or for children under the age of 18.
Do not take Naratriptan:
• If you are allergic (hypersensitive)to naratriptan, or any of the other ingredients (listed in Section 6)
• If you have a heart problem such as heart failure 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 take Naratriptan if your high blood pressure is mild and is being treated
• If you have kidney or liver disease
• With other migraine medicines, including those which contain ergotamine, or with similar medicines such as methysergide, or with other 5-HTi receptor agonists, such as sumatriptan.
If any of these apply to you:
> Tell your doctor, and do not take Naratriptan.
Take special care with Naratriptan
Your doctor needs to know certain information before you take Naratriptan.
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 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 taking Naratriptan, even though they had no signs of heart disease before.
If any of the points in the list 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 Naratriptan is prescribed for you.

> Tell your doctor if this applies to you. He or she may recommend you stop taking Naratriptan.
