What is Imigran

Imigran is a prescription medication designed to treat migraine - a neurological condition that usually involves severe recurring headaches. The illness may be accompanied by other symptoms, such as light and noise sensitivity, nausea and vomiting. This type of migraine is known as migraine with aura. These symptoms can also be experienced without a headache which is known as a silent migraine.

Imigran contains the active ingredient sumatriptan, which belongs to a class of medications known as selective serotonin receptor agonists, and treats the condition at its root.

Further information on migraines and Imigran can be found at NHS migraine.

Why choose Imigran?

Migraines can have a major impact on the quality of life of the people who experience them. The condition can interfere with work, education, hobbies, social and family life and personal relationships. In fact, the World Health Organisation includes severe migraine attacks on its list of most disabling illnesses. As such, for regular sufferers of migraine, it is a relief to find a product such as Imigran that can help lift this constant underlying threat.

Imigran was the first medication to contain sumatriptan to become available worldwide and was developed by multinational pharmaceutical company GlaxoSmithKline. It was designed and created to stimulate receptors in the brain to help blood vessels to contract back once they have widened, which is believed to be the cause of the migraine.

Can I buy Imigran online?

A prescription-only medication, Imigran, is now available with one and can be purchased online via Click Pharmacy after completing a simple assessment. Your answers help our doctors to determine whether this is the right medication for your situation at this time. You need only complete the form once, after which you can get a repeat order without redoing it.

How effective Is Imigran?

Imigran has an active ingredient known as sumatriptan which is part of a family of medications called triptans. It is designed to work quickly, in half an hour or less, and effectively in sufferers with intermittent but acute migraines and is to be taken once a migraine has begun rather than prior to the main symptoms appearing. It will not be effective in patients who experience less than ten episodes a month, but there are different forms of triptan which may work better for one person over another.

In contrast to regular painkillers, like ibuprofen and paracetamol, which act on the symptoms alone, sumatriptan works on the source of the problem, making it a better option for regular sufferers.

How does Imigran work?

Migraines are believed to be caused by blood vessels in the brain expanding which results in the throbbing sensation that most sufferers are familiar with. Imigran attacks the condition at its root by narrowing the blood vessels back to their normal size. This action helps to alleviate pain and other symptoms associated with this condition.

What dose should I choose?

Imigran is designed for adults between the ages of 18 and 65 only. One 50mg tablet should be taken when the first signs of a migraine are identified, and it’s vital that you do not exceed more than two tablets in 24 hours. You must carefully read the patient information leaflet that accompanies your medication before taking it, and if you have any questions or concerns about your dosage, you should contact your doctor or pharmacist.

How should I take Imigran?

Unlike some medications, Imigran is not affected by food, so it can be taken with or without a meal. One tablet should be swallowed whole with water at the onset a migraine attack, and if, after two hours or more, the symptoms are still ongoing or the headache comes back, you can take a second dose, up to a maximum 100mg a day. For more information, read the patient leaflet that comes with your medication.

Is it safe to use Imigran whilst pregnant or breastfeeding?

As when taking any medication whilst pregnant or breastfeeding, it is crucial you speak to a medical expert beforehand. You can book a free and confidential online appointment with one of the doctors at Click Pharmacy from the comfort of your own home, which may be preferable when heavily pregnant or dealing with a newborn.

There has been little research done on the effects of Imigran on the foetus, though based on the limited evidence available, there is nothing so far to suggest that there is a higher risk of birth defects. With regard to breastfeeding, though, it is highly recommended that you do not breastfeed for 12 or more hours after taking Imigran and any expressed milk during this time should be discarded.

Is it safe to use Imigran whilst taking other medication

It is vital you tell your Click Pharmacy doctor or GP about any other medications or supplements you are taking before beginning to use Imigran, as some medications either decrease the effectiveness of the drug or else cause adverse effects. The medications to be aware of include:

  • ergotamine
  • Monoamine oxidase inhibitors (MAOIs)
  • triptan or 5-HT
  • selective serotonin reuptake inhibitors (SSRIs)
  • serotonin and norepinephrine reuptake inhibitors (SNRIs)
  • St John’s Wort

What is the active ingredient in Imigran Tablets?

The active ingredient in Imigran Tablets is sumatriptan. This ingredient is effective at treating symptoms of migraines and cluster headaches.

Can I crush or chew Imigran Tablets?

No, you should refrain from crushing or chewing Imigran Tablets. If you experience difficulty swallowing tablets, you can break Imigran Tablets in half through the line in the middle.

How long does it take for Imigran Tablets to begin treating migraines?

After taking a tablet it should take around 30 to 60 minutes for your symptoms to improve. If your migraine returns after 2 hours you can take another dose.

What if my migraine returns after taking Imigran Tablets?

If after taking Imigran Tablets your migraine returns, then you can take another dose 2 hours after taking your previous dose.

What is the difference between Imigran Tablets and Sumatriptan Tablets?

While they are both effectively used to treat symptoms of a migraine and cluster headache, the main difference is branding. Imigran Tablets are the branded version of Sumatriptan Tablets, sumatriptan is the active ingredient in both of these drugs.

Can pregnant or breastfeeding women use Imigran Tablets?

It is usually safe for pregnant and breastfeeding women to use Imigran Tablets. However it is advised to speak to a GP, pharmacist or midwife before doing so.

Can I drink alcohol while taking Imigran Tablets?

Drinking alcohol does not interfere with Imigran Tablets and how they function. However if you are experiencing a migraine it is generally advised to not drink any alcohol.

Whilst considered to be safe and effective for most migraine sufferers, Imigran can cause a number of side effects in some people, including:

  • nausea
  • vomiting
  • tiredness
  • a heavy or tight chest
  • dizziness
  • numbness
  • hot flushes
  • drowsiness

These are usually mild and temporary; however, if they do not go away or you consider them severe, it’s important to tell your doctor. For a full list of side effects, check the guidelines that come with your tablets or consult a GP or pharmacist.

Always read the patient information leaflet before starting your treatment. The patient information can be found here.
