Zomig Rapimelt Tablets (2.5mg & 5mg)

Zomig Rapimelt is a branded prescription medication containing zolmitriptan — a second-generation triptan used for the acute treatment of migraine headaches in adults aged 18 to 65.

What sets Zomig Rapimelt apart from standard zolmitriptan tablets is its orodispersible format: each tablet dissolves instantly on the tongue without the need for water. This makes it particularly suitable for migraine sufferers who experience nausea or vomiting during an attack — where swallowing a conventional tablet can be difficult or impractical — and for those who do not have immediate access to water at the onset of a migraine.

Zomig Rapimelt is available in two strengths: 2.5mg and 5mg. It is manufactured by AstraZeneca and is licensed specifically for the acute treatment of migraine with or without aura in adults.

Zolmitriptan belongs to the triptan class of medicines, which work specifically on the mechanisms of migraine — rather than acting as general painkillers.

During a migraine attack, blood vessels around the brain dilate (widen), and the trigeminal nerve releases pain-signalling chemicals including CGRP (calcitonin gene-related peptide) and substance P. Zolmitriptan works by:

• Binding selectively to serotonin receptors (5-HT₁B/1D) in cranial blood vessels and the trigeminal nerve
• Constricting the dilated blood vessels that contribute to the throbbing pain of migraine
• Inhibiting the release of inflammatory neuropeptides from the trigeminal nerve — interrupting the pain signal at its source

As an orodispersible tablet, Zomig Rapimelt is absorbed through the oral mucosa as it dissolves on the tongue, potentially offering faster onset than a swallowed tablet that must first be dissolved in the stomach before absorption.

The orodispersible format offers practical advantages over conventional tablets, particularly for migraine sufferers:

• No water required — dissolves on the tongue in seconds; ideal if you are caught without water at the onset of an attack
• Easier to take during nausea — nausea is a common migraine symptom that can make swallowing tablets uncomfortable or cause them to be vomited back up; an orodispersible tablet bypasses this problem
• Rapid dissolution — absorbs quickly without the need to wait for a tablet to pass through the digestive system
• Discreet and portable — can be taken in any setting without preparation

For migraine sufferers who have previously struggled to take conventional tablets during an attack, the orodispersible format can significantly improve the practical effectiveness of treatment.

Zolmitriptan is available in several formats — each suited to different patient needs:

Zomig Rapimelt (orodispersible tablet):

• Dissolves on the tongue — no water needed
• Absorbed through oral mucosa during dissolution
• Available in 2.5mg and 5mg
• Suited to patients with nausea or swallowing difficulties
• Age restriction: 18–65 only

Standard zolmitriptan tablets:

• Swallowed with water in the conventional way
• Absorbed via the gastrointestinal tract
• Available in 2.5mg and 5mg

Zolmitriptan nasal spray (5mg):

• Absorbed directly through the nasal mucosa
• Fastest onset of the zolmitriptan formats — bypasses the digestive system entirely
• Suited to patients with severe nausea, vomiting, or who prefer a non-oral route
• Age restriction: 18+ (not limited to 65)

Your prescriber will advise which format and strength is most appropriate for your specific migraine pattern and needs.

Zomig Rapimelt is licensed for adults aged 18 to 65 with a confirmed diagnosis of migraine (with or without aura).

It may be particularly suited to patients who:

• Experience nausea or vomiting during migraine attacks
• Find swallowing conventional tablets difficult during an attack
• Do not always have water available at the onset of a migraine
• Have been previously prescribed Zomig or zolmitriptan and prefer the branded orodispersible format

• Are under 18 or over 65 years of age
• Have ischaemic heart disease, Prinzmetal's angina, or a history of heart attack or stroke
• Have a history of TIA (transient ischaemic attack / mini-stroke)
• Have uncontrolled high blood pressure
• Have peripheral vascular disease
• Have hemiplegic or basilar migraine
• Are taking MAO inhibitors (MAOIs) or have taken them within the last 2 weeks
• Are taking other triptans or ergotamine-based medicines concurrently
• Are taking St. John's Wort — this can interact with zolmitriptan
• Have phenylketonuria (PKU) — Zomig Rapimelt contains aspartame

Inform your prescriber if you:

• Smoke, or have recently stopped smoking
• Have high cholesterol, diabetes, or liver problems
• Take SSRIs or SNRIs — potential risk of serotonin syndrome

Our online consultation will assess your full medical history and current medications before any prescription is issued.

All prescribed medication should be used in accordance with your prescriber's instructions.

How to take:

• Place one tablet on your tongue at the onset of a migraine headache
• Allow it to dissolve completely — this takes only a few seconds
• The dissolved tablet is swallowed with saliva — no water is required
• Do not chew or swallow the tablet whole

Dosing:

• Starting dose: One tablet (2.5mg or 5mg as prescribed) taken as soon as a migraine headache begins
• If symptoms return: A second dose may be taken, but wait at least 2 hours after the first dose
• Maximum in 24 hours: 10mg total (four 2.5mg tablets or two 5mg tablets)

Important:

• Take at the onset of headache — not during the aura phase before headache begins
• Zomig Rapimelt is an acute treatment for active attacks only — it is not a preventative medicine and should not be taken daily
• Using triptans on more than 10 days per month can lead to medication overuse headache, making migraines more frequent. If you find yourself needing it this often, discuss a preventative treatment plan with your prescriber
• Contains aspartame — patients with phenylketonuria (PKU) should consult a doctor before use

Zomig Rapimelt is generally well tolerated. Side effects are usually mild and short-lived.

Common (may affect up to 1 in 10 people):

• Tingling sensations (paraesthesia) — typically in the fingers, toes, or skin
• Drowsiness, dizziness, or feeling unusually warm
• Dry mouth or stomach discomfort
• Muscle weakness
• Sensation of heaviness, tightness, or pressure — commonly felt in the throat, neck, or chest

Uncommon:

• Palpitations or uneven heartbeat
• Temporary increases in blood pressure

Stop use immediately and seek urgent medical attention if you experience:

• Chest pain or tightness that does not resolve within a few minutes
• Shortness of breath
• Sudden facial weakness, drooping, or difficulty speaking — potential stroke symptoms
• Swelling of the face, lips, or tongue — signs of allergic reaction
• Difficulty breathing

Do not take Zomig Rapimelt if you:

• Have or have had cardiovascular disease, heart attack, angina, or stroke
• Have uncontrolled high blood pressure
• Have hemiplegic or basilar migraine
• Are taking other triptans, ergotamine, or ergot derivatives — do not combine within 24 hours
• Are taking or have recently taken MAO inhibitors (MAOIs within the last 2 weeks)
• Are taking St. John's Wort
• Have phenylketonuria — this product contains aspartame

Inform your prescriber if you:

• Have risk factors for cardiovascular disease: smoking, high cholesterol, diabetes, strong family history
• Have liver impairment — dose adjustment may be required
• Take SSRIs or SNRIs regularly

Age restriction: Not recommended for patients under 18 or over 65. This age limit is specific to Zomig Rapimelt and narrower than some other triptans — it reflects the populations studied in the product's clinical trials.

Q: What is the difference between Zomig Rapimelt and standard zolmitriptan tablets? Both contain zolmitriptan as the active ingredient at the same strengths (2.5mg and 5mg). The difference is the tablet format: Zomig Rapimelt is an orodispersible tablet that dissolves on the tongue with no water required, while standard zolmitriptan tablets are swallowed with water in the conventional way. The orodispersible format is particularly useful during a migraine when nausea or lack of water makes taking a conventional tablet difficult.

Q: What does "orodispersible" mean? Orodispersible means the tablet dissolves rapidly when placed on the tongue — typically within seconds — without needing to be swallowed with water. The dissolved tablet is carried down with saliva. This is distinct from a standard tablet (which must be swallowed whole with liquid) and from a sublingual tablet (which dissolves under the tongue for direct absorption into the bloodstream).

Q: Is Zomig the same as zolmitriptan? Zomig Rapimelt is the branded version of zolmitriptan in orodispersible form, manufactured by AstraZeneca. Generic zolmitriptan orodispersible tablets contain the same active ingredient at the same dose. They may differ in inactive ingredients (excipients) — notably, Zomig Rapimelt contains aspartame, which may not be present in all generic versions. Always check the patient information leaflet for the specific product dispensed.

Q: How quickly does Zomig Rapimelt work? Most patients notice the onset of migraine relief within 30 to 60 minutes. The orodispersible format allows the tablet to begin dissolving and absorbing immediately on the tongue, which may contribute to a faster onset compared to a standard swallowed tablet. Taking the tablet as early as possible after the migraine headache begins — rather than waiting until pain is severe — typically produces the best results.

Q: Can I take Zomig Rapimelt if I am over 65? No. Zomig Rapimelt is licensed for adults aged 18 to 65 only. This age restriction is specific to this product and reflects the populations included in the clinical trials. If you are over 65 and require migraine treatment, speak to your GP about the most appropriate option for you.

Q: Can I take Zomig Rapimelt with paracetamol or ibuprofen? Yes, Zomig Rapimelt can generally be combined with paracetamol or ibuprofen. Some patients find this combination more effective than either medicine alone. Do not combine with other triptans or ergotamine-based medicines.

Q: What should I do if one tablet does not relieve my migraine? If a first dose provides partial relief but the migraine returns, a second tablet may be taken at least 2 hours after the first. The maximum dose in any 24-hour period is 10mg. If the first tablet provides no relief at all, do not take a second dose for the same attack — speak to your prescriber about whether a higher dose or a different triptan would be more appropriate.

Q: Can I use Zomig Rapimelt alongside my antidepressant? Some antidepressants — particularly SSRIs (e.g. sertraline, fluoxetine) and SNRIs (e.g. venlafaxine) — can interact with triptans, with a theoretical risk of serotonin syndrome. This does not necessarily mean prescribing is impossible, but it must be declared in your consultation. St. John's Wort — a herbal antidepressant — should not be taken alongside Zomig Rapimelt.

Q: Does Zomig Rapimelt contain aspartame? Yes. Zomig Rapimelt orodispersible tablets contain aspartame, a source of phenylalanine. If you have phenylketonuria (PKU) — a rare metabolic condition requiring a low-phenylalanine diet — you must consult a doctor before using this product. Declare PKU during your consultation.

Q: Can I take Zomig Rapimelt every day? No. Zomig Rapimelt is an acute treatment — it should only be taken during a migraine attack, not as a daily preventative. Using triptans on more than 10 days per month can cause medication overuse headache, making migraines more frequent and harder to treat. If you are having frequent attacks, discuss a preventative treatment plan with your prescriber.
