Relpax® contains the active ingredient eletriptan hydrobromide.

Relpax® is a serotonin agonist, that works by reducing the size of swollen blood vessels around the brain that may be involved in migraine.

Relpax® is used to treat a migraine attack.

Check with your pharmacist or doctor if you:

  • have any allergies to any other medicines or substances such as foods, dyes or preservatives.
  • have ever been told you may have an increased risk of heart or blood vessel disease:

Heart and blood vessel disease and high blood pressure sometimes do not cause any symptoms, so some people do not know if they have these problems.

Before deciding whether you should take Relpax®, your pharmacist or doctor will check with you for risk factors for coronary artery disease (CAD) such as high blood pressure, high cholesterol, smoking, obesity, diabetes, family history of CAD, post menopause in females and age over 40 years in males.

  • have any other health problems including liver or kidney problems.
  • are taking other medicines for migraine.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your pharmacist or doctor if you are pregnant or intend to become pregnant.

Talk to your pharmacist or doctor if you are breastfeeding or intend to breastfeed. You may be advised to stop breast-feeding for 24 hours after taking Relpax®.

Use in children and adolescents (under 18 years)

Do not use in children or adolescents under the age of 18 years.

Use in patients over 65 years

Use with caution as effects on blood pressure may be more marked than in younger adults.

3. What if I am taking other medicines?

Tell your pharmacist or doctor if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with Relpax® and affect how it works.

Caution should be exercised if you are taking medicines to treat depression such as:

  • SSRIs (Selective Serotonin Reuptake Inhibitors), such as citalopram, escitalopram, sertraline or fluoxetine;
  • SNRIs (Serotonin Norepinephrine Reuptake Inhibitors) such as desvenlafaxine, duloxetine, venlafaxine; and
  • St John’s Wort (botanical name Hypericum Perforatum, a herbal remedy used to treat mood disorders).

These medicines when taken with Relpax® may increase the risk of serotonin syndrome, a condition caused mainly by an excess in serotonin within the central nervous system. Symptoms include but are not limited to high blood pressure, a fast heart rate, agitation and sweating.

Medicines that may increase the effect of Relpax® include:

  • Do not take a second dose of Relpax® within 2 hours of taking the first dose.
  • If, after initial relief, your migraine comes back, take a second tablet. In this case, wait at least 2 hours between the first tablet and the second.
  • If Relpax® does not relieve your migraine, do not take a second dose for the same attack.
  • You may take something else for the pain, but do not take medicine containing ergotamine, dihydroergotamine or methysergide for at least 24 hours before or after taking Relpax®.
  • Relpax® will not prevent a migraine attack. If you take it before you get the headache, it will not be effective.
