Conditions Treated by Relpax
Eletriptan reduces the severity of migraine headaches in adults. It may provide relief to headaches whether they are without or with aura. “Aura” is a term, used to describe the warning symptoms that precede a migraine attack. A migraine headache is caused by the expansion of the temporal artery and other blood vessels, outside the skull and beneath the skin of the temple. The blood vessels stretch the nerves that coil around them. The nerves respond by releasing certain chemicals that cause pain and further dilation of the blood vessels. The increasing expansion of the blood vessels intensifies the headache. The pain is accompanied by nausea, dizziness and increased sensitivity to light. Relpax (eletriptan) serves to narrow the blood vessels around the brain. Furthermore, it reduces certain chemicals in the body that can trigger headaches, intolerance to light and sound and nausea. It may reduce the headache within half an hour. Relpax is not administered to prevent migraine headaches.
Relpax Dosage Information
a.) Typical Dosage Recommendations
You should take Relpax for your migraine headaches exactly as directed by your doctor. The recommended dose of Relpax for an adult is 20 mg tablets or 40 mg tablets. It should be taken with a glass of water at the very first sign of a headache. The dosage depends upon the severity of the headache, the body weight of the patient and other medications taken by the patient. If the headache reduces partially, you may take another dose after two hours or as recommended by your doctor. If the first dose is not effective, another dose might not be of any help either. Do not take more than two tablets of the prescribed dose in 24 hours. Consult your doctor if you have migraine headaches for more than three days in a month. Your doctor may want to administer the first dose in a clinic to determine if the medication affects you adversely. If you are prescribed Relpax for a long period, your doctor may advise you to go to the clinic for an electrocardiogram. The dosage may have to be adjusted following the results of the electrocardiogram.
b.) Missing a dose
Relpax is taken at the time of a migraine headache. It is not used to prevent or cure migraine and there is no regular schedule for taking the drug.
If you take an extra dose of Relpax, you must seek emergency medical help. An overdose could cause your blood pressure to rise. This may result in chest pain, irregular pulse or heartbeat, shortness of breath, blurred vision, confusion and seizures. You may experience other discomforts as well.
Relpax should not be taken without a doctor’s prescription. It should not be administered to a person less than eighteen years old. Do not take Relpax if you are intolerant to eletriptan or any other non-medicinal ingredients in the tablet.
