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

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
• 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.

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.
