What Sumatriptan Tablets are and what
they are used for

Sumatriptan belongs to a group of medicines called
triptanes, which are used to treat migraine headache.

Migraine symptoms may be caused by the temporary
widening of blood vessels in the head. Sumatriptan 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.

Sumatriptan works only when a migraine attack has
started. It will not stop you from getting an attack.

You must not use sumatriptan to prevent a migraine attack.

Before you take Sumatriptan Tablets

Do not take Sumatriptan
• if you are allergic (hypersensitive) to sumatriptan or any
of the other ingredients of Sumatriptan (see also “Take
special care with Sumatriptan” if you are allergic
(hypersensitive) to certain antibiotics (sulphonamides).
• if you have or have ever had heart problems, including a
heart attack, angina (chest pain caused by exercise or
effort), Prinzmetalʼs angina (chest pain which happens
at rest) or have experienced heart related symptoms
such as shortness of breath or pressure over the chest
• if you have problems with the blood circulation to your
hands and feet (peripheral vascular disease)
• if you have had a stroke/cerebral infarction, also
described as an “attack” or cerebral haemorrhage (CVA;
cerebrovascular accident)
• if you have had a temporary disturbance of the blood
supply to the brain that left little or no residual symptoms
(TIA)
• if you have severe liver function impairment
• if you have high blood pressure
• if you are taking drugs containing ergotamine or
ergotamine derivatives (migraine drugs such as
methysergide) or any triptan/5-HT1 receptor agonist.
These must not be taken at the same time as
Sumatriptan (see also “Taking other medicines”)
• if you are currently taking or stopped taking MAO
inhibitors (e.g. moclobemide for depression or selegiline
for Parkinson's disease) two weeks ago. See also
ʻTaking other medicinesʼ below.

Take special care with Sumatriptan
Before you start using Sumatriptan, you should tell your
doctor if:
• you are a heavy user of tobacco or products containing
nicotine (patches or chewing gum), especially if you are
a woman past the menopause or a man over 40 years.
The doctor should examine you first.
• you have liver or kidney impairment. The doctor might
adjust the dose.
• you have ever suffered seizures/fits (convulsions) or
have a predisposition to seizures/fits (convulsions);
sumatriptan can cause seizures/fits. Sumatriptan might
increase the risk of seizures.
• you are allergic (hypersensitive) to certain antibiotics
(sulphonamides). You may experience an allergic
reaction after taking sumatriptan. Caution is advisable.

Sumatriptan must only be used if a diagnosis of “migraine”
has been clearly established in your case and other factors
have been excluded. Certain forms of migraine cannot be
treated with sumatriptan.

After taking Sumatriptan you may feel pain in your chest
and a feeling of pressure for a short time. This can be quite
intensive and may radiate up towards your throat. In very
rare cases this may be caused by effects on your heart.
Therefore, if the symptoms do not disappear, contact your
doctor.

If you take Sumatriptan too often, your headache may
become worse. In this case, your doctor might recommend
you stop taking sumatriptan.

Taking other medicines
Please tell your doctor or pharmacist if you are taking or
have recently taken any other medicines, including
medicines obtained without a prescription.

An interaction means that medicines used at the same time
can influence the effect(s) and/or side effect(s) of each
other. The following comments may also apply to
medicines that you have used any time in the past or are to
use in the near future.

• medicines containing ergotamine (migraine drugs,
including methysergide) and triptans/5-HT1 receptor
agonists. These must not be taken at the same time as
Sumatriptan (see “Do not take Sumatriptan”). After
taking medicines containing ergotamine or another
triptan/5-HT1 receptor agonist, you are advised to wait
at least 24 hours before taking Sumatriptan. After taking
Sumatriptan you are advised to wait at least 6 hours
before taking medicines containing ergotamine and at
least 24 hours before taking another triptan/5-HT1
receptor agonist.
• MAO inhibitors (e.g. moclobemide for depression or
selegiline for Parkinson's disease). Sumatriptan must
not be taken at the same time as or within two weeks
after stopping use of MAO inhibitors.
• medicines for depression and other mental conditions
called SSRIs and SNRIs. Side effects may occur.
• lithium (for manic/depressive (bipolar) disorders)
• Herbal products containing St John´s wort (Hypericum
perforatum). Side effects may occur with greater
frequency.

Please note that the above medicines may be known to
you by other names, often the brand names. In this section
only the active ingredient or therapeutic group of the
medicine is given, and not the brand name. Always
thoroughly check the pack and information leaflet of the
medicines you are already using for the active ingredient or
therapeutic group of that medicine.

Pregnancy
During pregnancy, sumatriptan must only be taken
following consultation with your doctor. Sumatriptan should
be used during the pregnancy only if the potential benefit to
the mother outweighs the potential risk to the unborn child
and no other appropriate treatment option is available.

Breast-feeding
Sumatriptan passes into breast milk. You are advised not to
breastfeed within 12 hours after taking Sumatriptan. Do not
feed your child with milk expressed during this period.

Ask your doctor or pharmacist for advice before taking any
medicine.

Driving and using machines
Migraine itsself as well as using sumatriptan can cause
drowsiness, dizziness and weakness which may adversely
affect your speed of reaction. Wait until you have found out
how you react to sumatriptan before you drive or use
machines.
