The active ingredient here is Eletriptan hydrobromide. 20- 40 mg of this drug has proven to be effective in providing instant relief from acute symptoms of cluster headaches.

In this article, we’ll be taking you through the various aspects of Relpax 40, such as its uses, side effects, warnings, dosage and alternatives. Based on this, you can decide its suitability for your ailments.

Let’s start by understanding the causes and symptoms of cluster headaches.

What Are Cluster Headaches?

Cluster headaches are bouts of painful headaches occurring in cluster periods which last from anywhere to a week for days or months. Pain is in the form of severe, one-sided headache, or behind the eyes. It is accompanied by drooping of eyelids, tears and nasal discharge, followed by periods of remission (complete absence of headaches for varied periods).

The exact cause of these isn’t known. Some of the triggers include:

  • Alcohol or smoking
  • Strong smells like perfumes or deodorants
  • Blinding lights
  • High altitudes

However, some of these won’t trigger a cluster headache during remission.

How Does Relpax 40 Treat Cluster Headaches?

Cluster headaches are believed to be caused by dilation of brain vessels. The active ingredient in Relpax 40, eletriptan hydrobromide, affects a neurotransmitter called serotonin. This causes the brain vessels to narrow down and reduces nausea, headache and symptoms of a migraine for most people.

It stops pain signals from the brain and prevents the release of any other pain-inducing substances. However, it does not prevent the attacks completely but only reduces their frequency.

Uses of Relpax 40

Relpax 40 can only be used to treat headaches that have already begun. It falls under the category of triptan medicine, also known as selective serotonin receptor agonists.

Relpax 40 and its generic counterparts can be used to treat a wide range of conditions, including:

  • Migraines: Relpax 40 can be used for migraines. About 70% of people feel better within a few hours. However, people with skin sensitivity should consult a GP before consumption.
    Migraines are reportedly caused due to constriction of brain vessels. Relpax helps in dilating and reducing their activity and provides temporary relief.
  • Altitude sickness: This topic needs more research. According to a randomized survey, eletriptan provided relief from altitude sickness.

Now that we’re familiar with the uses of Relpax 40, let us see the dosage options.

Dosage of Relpax 40

Relpax 40 contains 48.5mg of eletriptan hydrobromide, which equals 40mg of eletriptan, and comes in a film-coated, orange tablet. It is round-shaped and convex. The dose can be repeated after 2 hours, if necessary.

The tablet contains more eletriptan than Relpax 20 and should be used mindfully. Also, not to forget, the tablets can be taken with or without food and water.

A single dose consists of 1 whole tablet. The daily dosage should not exceed 80mg, i.e. not more than 2 tablets a day. Moreover, the tablet best works when taken at the earliest sign of a headache.
