What is Zomig? 

Zomig is an authorised UK medicine containing zolmitriptan, a triptan-class prescribed medication designed for the quick relief of migraine attacks with or without aura. It works by targeting serotonin receptors, causing the widened blood vessels in the brain to narrow, and so easing headache pain and other migraine symptoms. Zomig is available as 2.5 mg tablets, offering fast onset of action when taken at the first sign of a migraine.

The medicine is supported by many clinical studies and is prescribed under strict dosage guidelines to ensure safety and effectiveness in migraine management. It remains a trusted option among UK medical practitioners universally.

What is Zomig Used For?

Acute Migraine Relief: Zomig is used to provide fast relief at the start of acute migraine attacks with or without aura.

Symptom Alleviation: It helps lessen other migraine symptoms, such as nausea, sensitivity to light, and sensitivity to sound.

Restoring Function: Zomig assists patients in returning to normal activities quickly by reducing the severity of migraine episodes.

At 123Meds, we offer Zomig exclusively for the acute treatment of migraine attacks only – if you are interested in using Zomig for any other condition, we advise you to seek further advice from your general practitioner to check whether it is a suitable treatment option.

How Zomig Works 

Zomig quickly relieves migraine symptoms by targeting specific serotonin receptors in the brain. It helps to reduce the swelling and widening of blood vessels associated with migraine attacks, thus easing pain and related symptoms.

Mechanism of Action: 

Selective Serotonin Receptor Agonism: Zomig selectively activates 5-HT1B/1D receptors on brain blood vessels, which is key to its effect.
Vasoconstriction: Activating these receptors causes the narrowed blood vessels in the brain to tighten further, effectively reducing migraine headache pain.
Inhibition of Neuropeptide Release: By stopping the release of vasoactive neuropeptides, Zomig helps to lower nerve-related inflammation, further easing migraine symptoms.

When is Migraine Confirmed, and Medication Needed? 

Migraine is confirmed when a person experiences frequent, moderate to severe headaches along with symptoms such as nausea, being very sensitive to light, sound, or smell, and having visual problems that affect daily life.

A proper diagnosis needs a full check including physical and neurological tests. Prescribed medication becomes necessary when migraines happen often, are very disruptive, or do not work with over‑the‑counter treatments, and when they disturb normal activities a lot. In these cases, medical practitioners may prescribe specific migraine treatments like Zomig to quickly ease symptoms and improve quality of life effectively.


Physical causes of Migraine: 

Hormonal Imbalances: Changes in oestrogen levels can trigger migraines, especially in women during their menstrual cycles.
Cardiovascular Factors: Irregular blood vessel reactions may cause migraine episodes by changing blood flow in the brain.
Environmental Triggers: Being exposed to bright lights, strong odours, or sudden weather changes can set off a migraine.

Psychological causes of Migraine: 

Stress: Constant stress is known to upset hormone levels, which may trigger migraine episodes.
Anxiety/Depression: Underlying anxiety or depression can make migraines more frequent and intense.

Symptoms of Migraine: 

Throbbing Headache: Strong pulsating head pain.
Nausea: A continuous upset stomach feeling.
Photophobia: Increased sensitivity to light.
If these symptoms last for weeks or longer, it is crucial to seek help from a medical practitioner. 

Medical practitioners will diagnose migraines based on your medical history and a careful evaluation. Depending on the triggers, treatment options may include prescribed medication like Zomig to quickly ease the symptoms. Depending on individual needs, other medications or treatments might also be advised. It is important to consult with a medical practitioner to choose the most suitable treatment plan.

Can Zomig Be Purchased Over the Counter? 

Zomig is a prescription-only medicine in the UK and cannot be bought over the counter. It needs a proper consultation with a medical practitioner, usually a general practitioner, who checks your condition, medical history, and possible risks before prescribing it.

This rule helps keep patients safe by stopping unsupervised use, lowering the risk of side effects and clashes with other medications, and making sure the treatment is proper for handling your migraine attacks effectively under close supervision.

Alternative Medications 

Alternative medications offer different choices for managing migraine symptoms when Zomig is not right or effective for an individual. These alternatives, mostly from the triptan family, work in a similar way to ease migraine pain and are prescribed with strict medical guidance to ensure safety and effectiveness.

Sumatriptan: Sumatriptan, a commonly used triptan, works much like Zomig by activating 5-HT1B/1D receptors to narrow widened blood vessels in the brain and ease migraine symptoms. It is available in several forms including tablets, nasal sprays, and injections, giving patients versatile choices for fast relief.

Naratriptan: Naratriptan, known for its longer lasting effect and better tolerability, is an effective alternative to Zomig by targeting serotonin receptors, reducing migraine pain and related symptoms. This allows patients more flexibility with the dose, especially helping those who experience long or recurring migraine episodes.

Rizatriptan: Rizatriptan, another useful triptan alternative, is well known for its fast action and dependable effectiveness. It works by stimulating serotonin receptors to ease migraine symptoms quickly, offering a valuable option for patients who need quick pain relief without the need for multiple doses.

If you're unsure which treatment is right for you, speak to your 123Meds prescriber for personalised advice and guidance.

How to Take Zomig? 

Timing: Take Zomig at the very first sign of your migraine symptoms.

Dosage: Zomig is prescribed as a 2.5 mg tablet that should be taken as soon as migraine symptoms start. For some patients, if symptoms do not go away, a second tablet may be taken after at least two hours, with a maximum recommended dose of 10 mg in 24 hours. Always follow your prescriber’s instructions. Do not take more than the prescribed dose, and make sure you are in a safe place when you take this medicine so you can watch its effects. If symptoms persist or get worse, seek prompt advice from your medical practitioner. Follow the label instructions carefully straight away.

With Food: Zomig can be taken with or without food. If you get stomach discomfort when taken without food, eating a light snack beforehand may help ease this. Always follow your prescriber’s dietary advice when using this medicine safely.

Avoid Consumption: When taking Zomig, avoid eating foods high in tyramine such as aged cheeses, processed meats, and fermented products. These foods may trigger migraine symptoms, so it is best to steer clear of them to reduce any possible interactions with the treatment.

If you missed a dose of Zomig, do not double the next dose; check with your medical practitioner for advice on how to proceed.

Zomig contains both active and inactive ingredients that work together to provide effective migraine relief.

Active Ingredient:

The active ingredient in Zomig is zolmitriptan, which works by selectively stimulating 5‑HT1B/1D receptors in the brain. This action causes the narrowing of widened blood vessels and quickly eases migraine symptoms.

Inactive Ingredients:

Inactive ingredients such as lactose monohydrate, maize starch, microcrystalline cellulose, and magnesium stearate help form the tablet, keep it stable, and aid in its absorption. Inactive ingredients may differ between manufacturers, so always check the packaging or contact us for more help.

It is important to watch how your body reacts when taking Zomig, as experiences can differ from one person to another. Knowing these effects can help you and your medical practitioner manage your treatment better.

Common Side Effects: 

Dizziness: Some users may feel dizzy after taking Zomig.
Tingling Sensations: Some people might notice a mild tingling in their limbs after a dose.
Nausea: A short feeling of nausea can occur in some individuals.
Dry Mouth: A dry mouth is sometimes reported after taking the tablet
Drowsiness: Users often feel sleepy after taking the tablet.
Fatigue: A general feeling of tiredness may follow the dose.
Muscle Weakness: Some individuals experience a slight weakness in their muscles.
Chest Discomfort: A brief period of chest discomfort may be noticed, though it usually does not last long.

Less Common but Serious Side Effects: 

Allergic Reaction: A serious allergic reaction can occur, needing quick medical care.
Cardiac Events: In rare cases, patients may experience heart problems such as a fast heartbeat or chest pain that need immediate evaluation.
Neurological Symptoms: Rare neurological signs, including sudden loss of vision or hearing issues, may occur and should be treated right away.

If you experience severe or lasting side effects such as sudden loss of vision or hearing issues, seek immediate help from your general practitioner, NHS111 or A&E to avoid further complications. Do not ignore unusual or worrying symptoms, as these are medical emergencies where quick care can prevent problems.

Before starting Zomig, please make sure you have told us about all your existing conditions so that your prescriber can decide on the best treatment and dose.

  • How many days in a row can I take Zomig?

    Zomig is meant strictly for the quick treatment of migraine attacks rather than everyday use. Using it for several days in a row is generally not advised unless your general practitioner specifically recommends it, as regular use may lead to overuse headaches or a reduction in its effectiveness.

  • How does Zomig make you feel?

    Zomig normally gives fast relief from migraine pain and related symptoms such as nausea and sensitivity to light. However, some individuals may feel dizziness, experience a tingling sensation, or feel slightly drowsy, with each person’s experience being different.

  • Can you buy Zomig over the counter?

    Zomig is a prescription-only medicine in the UK. This means it cannot be bought over the counter, and you need to speak to your healthcare provider, who will check your condition and prescribe it if it is suitable for your migraine management.

  • Is Zomig an opioid?

    No, Zomig is not an opioid. It is part of the triptan group of medications, which work by selectively activating serotonin receptors to ease migraine symptoms. It does not have the addictive qualities or strong central nervous system depressant effects that opioids possess.

  • Can you drink alcohol on Zomig?

    It is generally best to avoid or limit alcohol when taking Zomig, as alcohol might increase the chance of side effects and potentially trigger a migraine. Always consult your general practitioner for personalised advice regarding alcohol consumption during your treatment.

  • Who should not take Zomig?

    People with some heart or blood pressure problems, or a history of stroke or mini-strokes, should avoid Zomig. Also, anyone who is allergic to zolmitriptan or taking medicines that may interact with it should not use this treatment without first checking with their prescriber.

  • How fast does Zomig work?

    Zomig usually starts to work within 30 minutes to one hour after you take it, although the time can differ from one person to another. Some patients may feel relief very quickly, while others might need a bit more time for the full effects to be felt.

  • Can I take Zomig with paracetamol?

    Yes, Zomig can generally be taken with paracetamol as they work in different ways. Paracetamol may help further reduce migraine pain, but it is best to check with your general practitioner to make sure this combination is safe and right for you.

  • Does Zomig make you pee?

    Zomig is not known to act as a diuretic, so it usually does not cause you to urinate more. Its action is focused on serotonin receptors rather than affecting your kidneys. If you notice any unusual changes in your urinary habits, please consult your prescriber.

  • Is it safe to take Zomig everyday?

    Zomig is made for the quick treatment of migraine attacks rather than for daily use. Taking it every day is not advised because of the risk of overuse headaches and a decrease in its effectiveness. Always follow your general practioner’s advice about how often to use it.

  • Does Zomig cause hair loss?

    Hair loss is not a known side effect of Zomig. There is no strong proof linking zolmitriptan to hair loss in clinical studies. If you see any major changes in your hair or have worries, speak to your prescriber for further advice.

  • How much does Zomig cost?

    The price of Zomig can vary depending on the pharmacy and whether you get it on the NHS prescription or buy it privately. Costs may also differ by region. For the most accurate and current price, please check with your local pharmacy or the NHS.

  • Does Zomig increase serotonin?

    Zomig does not raise overall serotonin levels; instead, it selectively activates 5‑HT1B/1D receptors in the brain. This focused action helps ease migraine symptoms without causing a widespread increase in serotonin.

  • Can you take Zomig 3 days in a row?

    Although Zomig is designed for the quick treatment of migraine episodes, some individuals may need it for up to three consecutive days during long-lasting attacks. However, using it for several days in a row should only be done under strict medical guidance because regular use may heighten the risk of overuse headaches.

  • What does Zomig do to the brain?

    Zomig works by stimulating specific serotonin receptors, which makes the widened blood vessels in the brain tighten. This action cuts down nerve-related inflammation, easing migraine pain and other symptoms, and helps return brain function to normal during an attack.

  • Does Zomig cause weight gain?

    Weight gain is not a common or noted side effect of Zomig. Clinical studies do not generally link zolmitriptan to changes in body weight. If you notice unexpected weight changes, it is wise to discuss these concerns with your prescriber.

  • Can I drive on Zomig?

    Zomig may cause side effects such as dizziness, drowsiness, or difficulty concentrating in some users. It is important to check your own reaction to the medication before driving or operating machinery, and to avoid these activities if you feel impaired.
