The most common side effects

Overall, RELPAX is well tolerated. As with most medications, people taking RELPAX may have side effects. Usually, these are mild and do not last long.

Only a small percentage of people have side effects when taking RELPAX. In general, they are not bad enough to stop people from taking RELPAX. The most common side effects include:
  • Dizziness
  • Nausea
  • Weakness
  • Tiredness
  • Pain or pressure (in the chest or throat, for example)
In very rare cases, patients taking triptans, such as RELPAX, may experience serious side effects, including heart attacks. Call your doctor right away if you have severe chest pains and/or shortness of breath.

Other side effects

RELPAX: Hit Migraine Hard™
Important safety information

RELPAX is indicated for the acute treatment of migraine with or without aura in adults. Only your doctor can decide if RELPAX is right for you.

RELPAX should be taken as a single 40-mg tablet. If needed, and as directed by your healthcare professional, an additional 40-mg tablet can be taken at least 2 hours later. No more than two 40-mg tablets should be taken in any 24-hour period.

Most common side effects are dizziness, nausea, weakness, feeling sleepy, pain or pressure sensation in the chest or throat. Tell your doctor about any side effects you have.

If you have certain types of heart disease, a history of stroke, TIA, or uncontrolled blood pressure, you should not take RELPAX. Very rarely, certain people, even some without heart disease, have had serious heart-related problems. Talk to your doctor if you have risk factors for heart disease such as smoking, high blood pressure or high cholesterol, or if you are pregnant or nursing.

RELPAX, as with other drugs in its class (triptans), can cause serotonin syndrome, particularly when used with certain medications (SSRIs and SNRIs) commonly used to treat depression.

RELPAX should not be used within at least 72 hours of treatment with the following medicines: Nizoral®, Sporanox®, Serzone®, TAO®, Biaxin®, Norvir®, and Viracept®.
