About Relpax

What Relpax is used for

The name of your medicine is RELPAX. This medicine is one of a group of antimigraine drugs called 5-HT1 agonists.

RELPAX is intended to relieve your migraine headache and other associated symptoms of a migraine attack.

It can be obtained only by prescription from your doctor.

What Relpax does

Migraine headache is believed to be caused by a widening of the blood vessels in the head. RELPAX narrows the vessels and relieves the pain and other symptoms of migraine headache

When Relpax should not be used

RELPAX should not be used continuously to prevent or reduce the number of attacks you experience. Use RELPAX only to treat an actual migraine headache attack. RELPAX should not be used to relieve pain other than that associated with migraine headache.

Do not take RELPAX if you:

  • are allergic to any of the ingredients (see What the medicinal ingredient is: and What the nonmedicinal ingredients are:)

  • have uncontrolled or severe high blood pressure

  • have heart disease or history of heart disease

  • have severe liver disease

  • have or had a stroke or problems with your blood circulation, Raynaud syndrome or transient ischemic attacks (TIAs)

  • have taken any of the following medicines in the last 72 hours: ketoconazole (Nizoral), itraconazole (Sporanox), nefazodone (Serzone), troleandomycin (TAO), clarithromycin (Biaxin), ritonavir (Norvir), and nelfinavir (Viracept)? These medicines may cause an increase in the amount of RELPAX in the blood, increasing the risk of serious side effects.

  • have taken the following medicines in the last 24 hours: other “triptans” like almotriptan (Axert), sumatriptan (Imitrex), naratriptan (Amerge), zolmitriptan (Zomig), rizatriptan (Maxalt) or ergotamine-type medications such as ergotamine, dihydroergotamine or methysergide. These medicines are of the same class as RELPAX, and taking them together increases the risk of serious side effects.

Do not use RELPAX if you are pregnant, think you might be pregnant, are trying to become pregnant or are using inadequate contraception, unless you have discussed this with your physician.

Warnings and Precautions

The decision to use RELPAX is one that you and your doctor should make jointly, taking into account your individual preferences and medical circumstances. If you have risk factors for heart disease (such as high blood pressure, high cholesterol, obesity, diabetes, smoking, strong family history of heart disease, or you are a postmenopausal female or a male over 40), you should tell your doctor. Your doctor should evaluate you for heart disease in order to determine if RELPAX is appropriate for you.

Some medicines may increase the risk of serious side effects if taken concurrently with RELPAX.

Do not take RELPAX if you:

  • have taken any of the following medicines in the last 72 hours: ketoconazole (Nizoral), itraconazole (Sporanox), nefazodone (Serzone), troleandomycin (TAO), clarithromycin (Biaxin), ritonavir (Norvir), and nelfinavir (Viracept)?

Ask your physician for instructions about taking RELPAX if you are taking selective serotonin reuptake inhibitors (SSRIs) such as sertraline, escitalopram and fluoxetine or serotonin norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine, duloxetine for depression. A life-threatening condition called serotonin syndrome can happen when medicines called triptans, such as RELPAX, and medicines used to treat depression and mood disorders called SSRIs or SNRIs are used together. Signs and symptoms of serotonin syndrome include the following: restlessness, diarrhea, hallucinations, coma, loss of coordination, nausea, fast heart beat, vomiting, increased body temperature, changes in blood pressure and overactive reflexes.


Proper Use of Relpax

Usual dose

For adults, the dosage is 20 or 40 mg, as recommended by your physician. The dose should be taken as soon as your migraine appears, but it may be taken at any time during your migraine headache.

RELPAX tablets should be swallowed whole with water.

If your first dose is 20 mg, a second dose of 20 mg may be taken if your headache returns. Repeat doses cannot be taken any sooner than 2 hours following the first dose. Do not take more than 40 mg in any 24-hour period.

If the first dose does not relieve the symptoms, do not take further doses for the same attack.

A reminder: This medicine has been prescribed only for you. Only a doctor knows who can use it safely. Never give this medication to anyone else. It may harm them, even if their symptoms are the same as yours.

Overdose

If you have taken more medication than your physician has instructed, contact either your physician, hospital emergency department, or nearest poison control centre immediately.
