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-HT1 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-HT1 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.
If you are allergic to antibiotics called sulphonamides
If so, you may also be allergic to Naratriptan. 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 taking Naratriptan.
If you take Naratriptan frequently
Taking Naratriptan too often may make your headaches worse.
► Tell your doctor if this applies to you. He or she may recommend you stop taking Naratriptan.
If you feel pain or tightness in your chest after you take Naratriptan
These effects may be intense but they usually pass quickly. If they do not pass quickly, or they become
severe:
► Get medical help immediately. Section 4 of this leaflet has more information about these possible
side effects.
Taking other medicines and Naratriptan
Please tell your doctor if you are taking or have recently taken any other medicines. This includes any herbal
products or medicines obtained without a prescription.
Some medicines must not be taken with Naratriptan and others may cause adverse effects if they’re taken
with Naratriptan. You must tell your doctor if you are taking:
• any medicines for your migraine which contain any triptan or 5HT1 receptor agonist (such as sumatriptan
or zolmitriptan). Do not take Naratriptan at the same time as these medicines. Stop taking these
medicines at least 24 hours before taking Naratriptan.
• ergotamine also used to treat migraine, or similar medicines such as methysergide. Do not take
Naratriptan at the same time as these medicines. Stop taking these medicines at least 24 hours before
taking Naratriptan.
• any antidepressants classed as selective serotonin reuptake inhibitors (SSRIs), such as citalopram,
fluoxetine or paroxetine, or serotonin noradrenaline reuptake inhibitors (SNRIs) such as venlafaxine.
If you are not sure, talk to your doctor or pharmacist.
• St John’s Wort (Hypericum perforatum). Using herbal remedies that contain St John’s Wort while you are
taking Naratriptan may make side effects more likely.
Pregnancy and breast-feeding
• If you are pregnant or could be pregnant, ask your doctor or pharmacist (chemist) for advice before taking
any medicine. Talk to your doctor before you take Naratriptan. There is only limited information about the
safety of Naratriptan for pregnant women, though up till now there is no evidence of any increased risk of
birth defects. Your doctor may recommend that you do not take Naratriptan while you are pregnant.
• Do not breast-feed your baby for 24 hours after taking Naratriptan. If you express any breast milk during
this time, discard the milk and do not give it to your baby.

or use any tools or machines.
