Headache or Migraine?

Headaches

Headaches are usually bi-lateral - they are felt on both sides of the head. The pain is continuous until relieved by medicine and often finked to common triggers such as tiredness, excess alcohol, menstruation etc. Although they may be severe they usually respond to over-the-counter pain killers. It is said that psychogenic headaches (possibly caused by depression) do not respond to painkillers. They may be linked to changes in natural endorphin levels.

Migraines

Migraines are generally one-sided and the pain is throbbing - like a pulse. They occur with or without known triggers and may last for several days. They do not respond to regular painkillers. They are often preceded by warning signs - called auras by some. These include coldness and tingling around the mouth and in the hands, flashing lights, spots or wavy lines in the vision, which can be one-sided. These may be caused by ischaemia - reduced blood supply due to intense vasoconstriction - or by pressure of swollen tissue surrounding the nerve. Some time after the initial phase of cerebral vaso-const

riction - contraction of blood vessels in the brain - an intense pain begins, usually in one area, often above the 'eye. This pain tends to pulsate for hours or days and is thought to be due to intense extra-cerebral vaso-dilation - expansion of blood vessels outside the brain. It is frequently accompanied by sweating, nausea and vomiting. Noise and light usually make migraines much worse. General 'fuzziness' and mi

ld pain may persist for days after the main event has subsided.

Frequently asked Questions about Sumatriptan (Generic Imitrex)

Imitrex Generic is one of a class of drugs developed specifically to treat migraine headaches.


How does Sumatriptan (Generic Imitrex) work?


Migraine is believed to be caused due to widening of the blood vessels in the brain. Sumatriptan, which is a serotonin agonist, works by stimulating serotonin receptors. This effect leads to a narrowing of the blood vessels. Imitrex has been studied and approved by the FDA for the prevention of onset of migraine. Many news and forums on the drug describe it as the “migraine killer”, a term that can be applied effectively when the drug is taken just as the symptoms of migraine appear.


Side effects of Sumatriptan (Generic Imitrex)


Imitrex side effects occur commonly in most patients and include low severity symptoms such as nausea, diarrhea, muscle pain, skin reddening, feeling of heaviness, sneezing, runny nose, cough, irritated nose or throat, unusual taste in mouth, and sleepiness. There are also some dangerous Imitrex side effects that require medical attention; these include chest pain, sudden numbing of one side of the body, confusion and imbalance, increased heart rate and agitation, severe stomach and body pains, bloody diarrhea, seizures, and bluing of fingers and toes.

Sumatriptan tablets should never be administered to adolescents or children under the age of 18 and adults aged 65 years and above. For such patients, doctors should prescribe alternative treatments.


Guidelines before taking Imitrex


Imitrex cannot prevent migraines; it can only reduce severity of symptoms. This medication should not be taken to treat regular headaches. Keep a gap of at least two hours between successive dosages of Imitrex but do not extend the dosage beyond 300mg in a 24 hour period. Imitrex is not advisable for heart attack patients or those who have angina, stroke or high blood pressure.


Difference between Brand Imitrex and Generic Sumatriptan


GlaxoSmithKline owns and manufactures the branded Plavix, while generic Sumatriptan drug is manufactured by Sun Pharma and several other manufacturers. Brand Plavix has received approval from FDA, while generic alternatives are based on this approval of Sumatriptan. Other differences between the two versions lie in the colour of the tablets, their shapes and sizes.


Where and how to buy generic Imitrex?


Generic Imitrex is more widely available than the brand and is easily available through online pharmacies. Once you have a prescription, you can buy generic Imitrex online at cheap discount prices as many online pharmacies offer the medication at a special price. Buying online is a good option for patients who are restricted to their homes as they have the option of overnight home delivery.

Imitrex - Best Solution for Migraines

Many people experience migraine relief when taking Imitrex. The drug, which is available in tablet, nasal spray, or injectable form, works by narrowing blood vessels believed to become dilated during a migraine. When returned to their normal state, migraine symptoms often improve. Although the medication can be taken once a migraine starts, it cannot be taken to prevent migraines.

An Overview of Migraines and Imitrex

Imitrex is a prescription drug used for the treatment of migraine headaches once they start. The drug does not help prevent migraines.
A migraine headache is a severe, intense, throbbing pain felt on one, and sometimes both, sides of the head. The pain is mostly in the front around the temples or behind one eye or ear. Besides pain, other migraine symptoms may include nausea, vomiting, and sensitivity to light and sound. Migraine pain can last a few hours or up to one or two days.
Migraine research scientists do not know the specific cause of migraines, although they believe that overly sensitive blood vessels may play a role.
Treatment options for migraine relief will depend on a number of factors, including their severity and frequency. For some people, over-the-counter medicines, such as acetaminophen or prescription nonsteroidal anti-inflammatory drugs (NSAIDS) may be effective. For other people, stronger migraine medications are needed. One option is Imitrex.

How Does Imitrex Work to Treat Migraine Headaches?

Imitrex is part of a class of medications called 5-HT agonists (or more commonly known as "triptans"). During a migraine headache, some of the blood vessels in the head can become dilated (wider than they usually are). Imitrex works by narrowing these blood vessels, helping them return to their normal state. This action helps to relieve migraine symptoms.
Imitrex should be taken as soon as possible once a migraine starts. If your headache comes back or does not go away, you may take a second dose of Imitrex after waiting at least two hours from the time you took the first dose of Imitrex tablets or Imitrex nasal spray (or one hour after the first dose of an Imitrex injection). Let your healthcare provider know if Imitrex does not work completely after one dose.

Final Thoughts

Imitrex is a prescription medicine used for treating migraines. It does not prevent migraines from occurring . Although the drug is quite effective in treating migraine headaches, it is not right for everyone. It can also cause side effects in some people, such as tingling, dizziness, and chest discomfort.

Migraine Medications



Migraine is a medical condition. Most people who suffer from migraines get headaches that can be quite severe. A migraine headache is usually an intense, throbbing pain on one, or sometimes, both sides of the head. Most people with migraine headache feel the pain in the temples or behind one eye or ear, although any part of the head can be involved. Besides pain, migraine also can cause nausea and vomiting and sensitivity to light and sound. Migraine can occur any time of the day, though it often starts in the morning. The pain can last a few hours or up to one or two days. Some people get migraines once or twice a week. But migraine attacks can interfere with your day-to-day life.
We don’t know what causes migraine, but some things are more common in people who have them:
- Most often, migraine affects people between the ages of 15 and 55.
- Most people have a family history of migraine or of disabling headache.
- They are more common in women.
- Migraine often becomes less severe and less frequent with age.

Most researchers think that migraine is due to abnormal changes in levels of substances that are naturally produced in the brain. When the levels of these substances increase, they can cause inflammation. This inflammation then causes blood vessels in the brain to swell and press on nearby nerves, causing pain.
If you get migraine headaches, talk with your doctor. Before your appointment, write down:
- how often you have headaches
- where the pain is
- how long the headaches last
- when the headaches happen, such as during your period
- other symptoms, such as nausea or blind spots
- any family history of migraine
- all the medicines that you are taking for all your medical problems, even the over-the-counter medicines
- all the medicines you have taken in the past that you can recall and, if possible, the doses you took and any side effects you had
Migraine has no cure. But your migraines can be managed with your doctor’s help. Together, you will find ways to treat migraine symptoms when they happen, as well as ways to help make your migraines less frequent and severe. Your treatment plan may include some or all of these methods.
Medicine. There are two ways to approach the treatment of migraines with drugs: stopping a migraine in progress (called “abortive” or “acute” treatment) and prevention. Many people with migraine use both forms of treatment.
