1. what relpax is and what it is used for

Relpax contains the active substance eletriptan.

Relpax is one of a group of medicines called serotonin receptor agonists. Serotonin is a natural substance found in the brain that helps to narrow the blood vessels.

Relpax can be used to treat migraine headache with or without aura in adults. Before the start of a migraine headache, you may experience a phase called an aura, which can involve vision disorders, numbness and speech disorders.

2. what you need to know before you take relpax if you are allergic (hypersensitive) to eletriptan, or any of the other ingredients of this medicine (listed in section 6).

• If you have severe liver or kidney disease.
• If you have moderate to severe high blood pressure or untreated mild high blood pressure.
• If you have ever had heart problems, [e.g. heart attack, angina, heart failure or significant abnormal heart rhythm (arrhythmia), temporary, sudden narrowing of one of the coronary arteries].
• If you have poor circulation (peripheral vascular disease).
• If you have ever had a stroke (even a mild one that lasted for only a few minutes or hours).
• If you have taken ergotamine or medicines like ergotamine (including methysergide) within 24 hours before or after taking Relpax.

If you are taking any other medicines that end in ‘triptan’ (for example sumatriptan, rizatriptan, naratriptan, zolmitriptan, almotriptan and frovatriptan).

Please consult your doctor and do not take Relpax, if these statements apply to you now or have applied to you at any time in the past.
