Relpax, also known by its generic name eletriptan, is a prescription medication used to treat migraines. This article delves into the various aspects of Relpax, from its mechanism of action to its side effects, usage guidelines, and more.

What is Relpax?

Relpax is a type of medication known as a triptan, which is specifically designed to treat migraines. It is not intended for the prevention of migraines, but rather for the relief of symptoms once a migraine has started.

It works by narrowing blood vessels in the brain and blocking the release of substances that cause pain, nausea, and other symptoms associated with migraines. By doing so, it helps to alleviate the debilitating effects of a migraine attack.

How to Use Relpax

Dosage Guidelines

Relpax is typically prescribed in doses of 20mg or 40mg, to be taken orally at the onset of a migraine. If the migraine does not improve or worsens after the first dose, a second dose may be taken, but not sooner than two hours after the first dose.

However, the total daily dosage should not exceed 80mg. It's important to follow your doctor's instructions closely when taking Relpax, as overuse can lead to medication overuse headaches, or even heart problems.

Before starting Relpax, it's crucial to discuss your medical history with your doctor, particularly if you have a history of heart problems, high blood pressure, high cholesterol, diabetes, or if you smoke. Relpax can increase your risk of heart attack or stroke, especially if you have any of these risk factors.

Additionally, Relpax can interact with certain medications, including other migraine medications, antidepressants, and some herbal products. Always inform your doctor of any other medications or supplements you are taking.

Side Effects of Relpax

Like all medications, Relpax can cause side effects. Common side effects include dizziness, nausea, weakness, and drowsiness. These are usually mild and go away on their own as your body adjusts to the medication.

However, some side effects can be serious. Seek immediate medical attention if you experience chest pain, irregular heartbeat, severe stomach pain, bloody diarrhea, or signs of a stroke such as sudden numbness or weakness on one side of the body, slurred speech, or sudden vision changes.

Effectiveness of Relpax

Studies have shown that Relpax is effective in relieving migraine symptoms. In clinical trials, more than half of the patients who took Relpax reported relief from their migraine symptoms within two hours of taking the medication.

However, individual responses to Relpax can vary. Some people may find that Relpax does not provide sufficient relief, or they may not tolerate the side effects well. In such cases, other treatment options may be explored.


Relpax is a valuable tool in the arsenal against migraines. By understanding how it works, how to use it safely, and what to expect in terms of side effects and effectiveness, you can make an informed decision about whether Relpax is the right treatment option for you.

As always, it's important to discuss any questions or concerns with your healthcare provider. They can provide personalized advice based on your specific health situation and needs.
