Relpax Information

medically reviewed by Dr. HaVy Ngo, Pharmacist on July 15, 2025.

Relpax and Eletriptan at CanadaPharmacyOnline.com

The Brand Relpax, manufactured by Pfizer, is available in many countries worldwide, including Turkey and the United Kingdom. Upjohn manufactures and markets Relpax in Canada.

Generic eletriptan is sourced from manufacturers that meet applicable regulatory standards. The specific manufacturer of your dispensed medication may vary.

Important Information about Generic Eletriptan:

Generic eletriptan contains the same active ingredient as the brand-name Relpax and is required to meet the same safety, effectiveness, and quality standards as the brand-name product. This means it is designed to work in the same way as Relpax. Studies have demonstrated bioequivalence between generic and brand-name eletriptan, meaning they have comparable absorption rates and overall effects. However, individual responses to any medication can vary. If you have any questions about using generic eletriptan, talk to your doctor or pharmacist.

For more information about generic drug approval and bioequivalence, please refer to Access to Generic Drugs in Canada | Canada.ca.

Dosage:

Relpax and eletriptan are available as 20 mg and 40 mg oral tablets.

Your doctor will determine the appropriate dosage based on the individual needs and medical conditions.

Usage:

Relpax (eletriptan) is a prescription medication used to treat acute migraine attacks with or without aura in adults (18 years of age or older). A migraine is a type of headache that can cause severe throbbing pain, often on one side of the head, and is frequently accompanied by nausea, vomiting, and sensitivity to light and sound. Relpax is not used to prevent migraines and does not treat cluster headaches.

Mechanism of Action:
Relpax (eletriptan) works to relieve migraine symptoms by stimulating serotonin 5-HT1 receptors. This action has two key effects: it constricts certain blood vessels in the brain, and it inhibits the release of pro-inflammatory neuropeptides from the trigeminal nerves. These combined actions reduce pain and other associated migraine symptoms during an attack.

Take Relpax exactly as your doctor prescribes. Do not change your dosage or stop taking the medication without consulting your doctor. Follow the instructions in the product monograph in Canada: https://pdf.hres.ca/dpd_pm/00028130.PDF. Consult your doctor for personalized guidance and safe use.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before taking Relpax, it is essential to discuss all potential side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below is a partial list of side effects; individual reactions can vary. Before starting Relpax, it is crucial to discuss potential side effects and risks with your doctor or pharmacist.

Common side effects – These are examples of some common side effects of Relpax, but other side effects are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning or if you experience any other concerning symptoms.
• Dizzines
• Drowsiness
• Dry mouth
• Nausea
• Numbness or tingling
• Weakness

Serious or rare side effects – Stop taking Relpax and seek immediate medical attention right away if you experience any of the following:
• Allergic reactions, including angioedema, hives, and trouble breathing
• Heart problems, including sudden shortness of breath, severe chest pain, pain spreading to your jaw or shoulder
• Increase in blood pressure
• Stroke, including sudden numbness or weakness, sudden severe headache, slurred speech, vision problems
• Vision loss

Contraindications:

This is not an exhaustive list of contraindications. It is crucial to discuss all your medical conditions, past and present, and all medications you are using with your doctor or pharmacist before starting Relpax.

Relpax should not be used if:
• You are allergic to eletriptan or any of the inactive ingredients in Relpax
• You are taking another triptan medication or an ergot-type medicine within 24 hours
• You are taking or have taken a monoamine oxidase inhibitor (MAOI) within the last 14 days
• You have a history of stroke, heart attack, or transient ischemic attack (TIA)
• You have hemiplegic or basilar migraines
• You have ischemic bowel disease
• You have peripheral vascular disease
• You have severe liver problems
• You have uncontrolled high blood pressure

Tell your doctor about all of your medical conditions, past and present, before starting Relpax. This is crucial because certain conditions affect whether Relpax is right for you. These conditions may include, but are not limited to:
• Diabetes
• Family history of heart problems or stroke
• High cholesterol
• Kidney problems
• Liver problems

Dizziness and Impaired Driving Risk:
Relpax can cause blurred vision, dizziness, drowsiness, or tiredness. These effects may impair your concentration and reaction time. Do not drive, operate heavy machinery, or engage in tasks requiring full alertness until you can do so safely and know how Relpax affects you. If you have concerns, speak with your doctor or pharmacist.

Lactose Intolerance:
Relpax contains lactose. Inform your doctor if you have an intolerance to lactose or other sugars.

Medication Overuse Headache (MOH):
Overuse of migraine medications can lead to MOH, which is a worsening of headaches. Your doctor should evaluate you for MOH if your headaches become frequent or worsen in intensity.

Serotonin Syndrome:
You may experience serotonin syndrome if you use Relpax with other antidepressant medicines. Serotonin syndrome is a serious and life-threatening problem with symptoms such as mental changes, fast heartbeat, high body temperature, changes in blood pressure, tight muscles, and difficulty walking.

Drug Interactions:

Before taking Relpax, it is essential to discuss all potential risks and interactions with your doctor or pharmacist. For complete information about potential drug interactions, please consult the official Relpax website at https://www.relpax.com/en and discuss any concerns with your healthcare provider.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, and herbal supplements. Relpax can interact with other medicines but is not limited to;
• Monoamine Oxidase Inhibitors (MAOIs): Using Relpax with MAOIs (such as isocarboxazid, phenelzine, or selegiline), or within 14 days of stopping an MAOI, is contraindicated and could be dangerous. This is because MAOIs can significantly increase the amount of eletriptan in your body, raising the risk of severe side effects. This combination also increases the risk of a serious condition called serotonin syndrome.
• Other triptans or ergot-type medications (e.g., almotriptan, sumatriptan, ergotamine, dihydroergotamine): Using these medications within 24 hours of using Relpax can cause additive vasoconstrictor effects.
• SSRIs and SNRIs (e.g., sertraline, fluoxetine, duloxetine, venlafaxine) can increase the risk of serotonin syndrome, a life-threatening condition.
• Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin, ritonavir): These can significantly increase eletriptan levels and increase the risk of side effects

Grapefruit:
Do not consume grapefruit products while taking Relpax. Grapefruit can increase Relpax levels in your blood, increasing your risk of side effects.

Pregnancy and Breastfeeding:

If you are pregnant or become pregnant, tell your doctor before taking Relpax. The safety and effectiveness of this drug during pregnancy have not been established. It is essential to discuss the risks and benefits of taking Relpax with your doctor before starting treatment. If you are breastfeeding or plan to breastfeed, inform your doctor. Eletriptan is excreted in human breast milk. Avoid breastfeeding for at least 24 hours after taking Relpax. Discuss the risks and benefits of taking Relpax with your doctor before taking it.
