1. What Sumatriptan tablets are and what they are used for
Sumatriptan Tablets have been developed for the treatment of migraine. The symptoms of migraine, which are thought to be due to temporary swelling ofblood vessels in the head, may include aura (warning sensations of visual distortion such as flashes oflight and zigzag lines or waves). Medicines like Sumatriptan Tablets are believed to work by reducing the size of these blood vessels. These medicines are called 5HT1 receptor agonists.
2. What you need to know before you take Sumatriptan tablets Do not take Sumatriptan tablets and tell your doctor if you:
• are allergic to sumatriptan or any of the other ingredients in Sumatriptan Tablets. You may be allergic if after taking sumatriptan, you suddenly experience feelings of tightness in the throat or chest, swelling of the tongue, lips or eyelids, difficulty in breathing or swallowing, a widespread feeling of warmth, flushing or itching of the skin and/or a rash like ‘hives’, progressing to feeling faint or loss of consciousness. Should any of these occur, stop taking the sumatriptan tablets and get medical assistance immediately.
• have had a heart attack or suffer from any heart disease.
• have symptoms that might indicate heart disease, such as chest pain or a sensation of pressure or tightness in your chest.
• have high blood pressure, or if your blood pressure is high despite medication.
• have poor blood circulation in your legs that causes cramp-like pain when you walk too far (peripheral vascular disease).
• have a history of stroke or transient ischaemic attack (TIA, a minor form of stroke that lasts less than 24 hrs).
• have severe liver problems.
• are taking any medicines for your migraine which contain ergotamine or ergotamine derivatives, such as ergotamine tartrate or any other triptan/5-HT1 receptor agonist, or methysergide maleate. You should stop taking the above at least 24 hours before taking Sumatriptan Tablets. You should
also wait at least 6 hours after taking Sumatriptan Tablets before taking an ergotamine-containing product or at least 24 hours before taking a triptan/5HT1 receptor agonist.
• are taking any medicines on a doctor’s prescription for the treatment of depression such as lithium, monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) (including citalopram, fluoxetine, fluvoxamine, paroxetine and sertraline) or if you have taken an MAOI in the last 2 weeks.
If you think you may have any of these problems contact your doctor before taking sumatriptan.
Before prescribing sumatriptan, your doctor will establish whether your headache is caused by
migraine and not by any other condition.
Warnings and precautions
You should tell your doctor before starting sumatriptan if any of these apply to you:
• if you know that you have problems with your liver or kidneys;
• if you have been diagnosed with epilepsy or any other disease that reduces the threshold for epileptic fits;
• if you know that you are allergic to antibacterial medicines that belong to the group of sulphonamides;
• if you are being treated for high blood pressure as in a small number of cases sumatriptan has been seen to increase blood pressure;
• if you experience pain and/or tightness in the chest or throat. These effects are usually short lasting. If they however persist and you are concerned, or they become severe, contact your doctor immediately for advice;
• if you experience chronic daily headaches. Taking sumatriptan too often may result in developing a chronic headache. In such cases you should contact your doctor as you may have to stop taking sumatriptan;
• if you are considered to be at risk of developing heart disease (e.g. diabetic or a heavy smoker), and particularly if you are a post-menopausal woman or a man over 40 years with these risk factors, your doctor should check your heart function before prescribing sumatriptan. In very rare cases serious heart conditions have occurred after taking sumatriptan, even if no signs of any heart disease were found. Contact your doctor for advice if you have any concerns.

3. How to take Sumatriptan tablets
Always take this medicine exactly as your doctor has told you. If you are not sure, check with your doctor or pharmacist.
ONE tablet should be taken at the first sign of a migraine attack, although it will still be effective if taken at a later stage. If this tablet does not make your migraine better do not take any more tablets for this attack because it is unlikely that a second dose will work. Sumatriptan Tablets can be used for your next attack.
If, after your first dose, your migraine goes away but then returns, you may take another tablet, provided it is at least two hours since you took the first tablet.
DO NOT TAKE MORE THAN 300 mg of Sumatriptan in any 24-hour period. Swallow each tablet whole with water. Do not chew or crush them.
Use in children and adolescents
Sumatriptan Tablets should not be used in children under 18 years of age, as the safety and effectiveness of this medicine in children has not been established.
Use in older people
There is little experience of Sumatriptan Tablets in those over 65 years of age so it is not usually prescribed for this age group.
If you have the impression that the effect of Sumatriptan Tablets is too strong or too weak, talk to your doctor or pharmacist.
How quickly will the treatment start to work?
It takes Sumatriptan Tablets about 30 minutes to start working. If the tablets do not ease your migraine, then you may take your usual ‘pain killers’, provided they do not contain ergotamine or its derivatives. Wait at least six hours after taking a Sumatriptan tablet before taking any medicines containing ergotamine or its derivatives.
If you take more Sumatriptan Tablets than you should:
It is important to keep to the dose on the label or follow the instructions above. Taking more than this could make you ill. If an overdose is taken, DO NOT DELAY, ask your doctor what to do or contact your nearest accident and emergency department.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
