Please read this information before you start taking RELPAX and each time you renew your prescription. Remember, this summary does not take the place of discussions with your doctor. You and your doctor should discuss RELPAX when you start taking your medication and at regular checkups.
What is RELPAX?
RELPAX is a prescription medicine used to treat migraine headaches in adults. RELPAX is not for other types of headaches.
What is a Migraine Headache?
Migraine is an intense, throbbing headache. You may have pain on one or both sides of your head. You may have nausea and vomiting, and be sensitive to light and noise. The pain and symptoms of a migraine headache can be worse than a common headache. Some women get migraines around the time of their menstrual period. Some people have visual symptoms before the headache, such as flashing lights or wavy lines, called an aura.
How Does RELPAX Work?
Treatment with RELPAX reduces swelling of blood vessels surrounding the brain. This swelling is associated with the headache pain of a migraine attack. RELPAX blocks the release of substances from nerve endings that cause more pain and other symptoms like nausea, and sensitivity to light and sound.
It is thought that these actions contribute to relief of your symptoms by RELPAX.
Who should not take RELPAX?
Do not take RELPAX if you:
- have uncontrolled high blood pressure.
- have heart disease or a history of heart disease.
- have hemiplegic or basilar migraine (if you are not sure about this, ask your doctor).
- have or had a stroke or problems with your blood circulation.
- have serious liver problems.
- have taken any of the following medicines in the last 24 hours: other "triptans" like almotriptan (Axert®), frovatriptan (Frova™), naratriptan (Amerge®), rizatriptan (Maxalt®), sumatriptan (Imitrex®), zolmitriptan (Zomig®); ergotamines like Bellergal-S®, Cafergot®, Ergomar®, Wigraine®; dihydroergotamine like D.H.E. 45® or Migranal®; or methysergide (Sansert®). These medicines have side effects similar to RELPAX.*

Tell your doctor about all the medicines you take or plan to take, including prescription and non-prescription medicines, supplements, and herbal remedies. Your doctor will decide if you can take RELPAX with your other medicines.
Some medicines used in treating depression such as the selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) may cause a condition called serotonin syndrome especially during combined use with certain migraine medications. Your doctor needs to know if you are taking any of these medicines, when taking Relpax.
