Quick Summary
- Prescription-only triptan for the acute treatment of migraine attacks with or without aura.
- Helps ease headache pain and associated symptoms such as nausea and sensitivity to light/sound.
- Take 1 tablet at migraine onset; if the migraine returns, a second dose may be taken after at least 2 hours (max 10mg in 24 hours; no more than 2 doses unless your prescriber advises).
- Not for migraine prevention and not for other headache types unless diagnosed/approved by a clinician.
What is Zolmitriptan?
Zolmitriptan is a ‘triptan’ medicine (a selective 5‑HT1B/1D receptor agonist) used to treat a migraine attack after it starts. It targets migraine pathways to help reduce pain and related symptoms during an active attack.
What Zolmitriptan is Used For
- Acute treatment of migraine attacks with or without aura in adults with a confirmed migraine diagnosis.
- Not for migraine prevention and not for cluster headache (unless specifically prescribed).
How Zolmitriptan Works (Mechanism)
During a migraine, pain pathways become overactive and blood vessels in the head may widen. Zolmitriptan acts on specific serotonin (5‑HT1) receptors involved in migraine pathways, helping to reverse migraine-related changes and improve symptoms.
Strengths & Dosing (2.5mg vs 5mg)
| Strength | Typical use (example) | Key notes |
| Zolmitriptan 2.5mg tablets | Common starting dose for many adults | Take at migraine onset. Your clinician may keep you at 2.5mg if effective. |
| Zolmitriptan 5mg tablets | Used when a higher dose is needed (clinician-led) | Some patients respond better to 5mg; follow your prescriber’s plan. |
How to Take Zolmitriptan (Dosage & Directions)
- Take exactly as prescribed.
- Take 1 tablet at the onset of migraine symptoms (it may still help later in the attack).
- If the migraine returns after initial relief, you may take a second dose after at least 2 hours (if advised).
- Do not take more than 2 doses in 24 hours unless your prescriber advises.
- The total zolmitriptan dose in 24 hours should not exceed 10mg (typical guidance).
- If the first dose provides no relief for that attack, do not take a second dose for the same attack unless your prescriber advises.
How Fast Does Zolmitriptan Work?
- Many people assess improvement within about 1 hour (individual response varies).
- For best results, take at migraine onset as prescribed.
Who Can Use Zolmitriptan?
- Adults with a confirmed migraine diagnosis where a clinician considers zolmitriptan suitable.
- A clinician should review migraine type, cardiovascular risk, and current medicines before prescribing.
Who Should NOT Use Zolmitriptan (Contraindications / Exclusions)
- Heart disease or significant circulation problems (including angina/previous heart attack).
- History of stroke or TIA.
- Uncontrolled high blood pressure.
- Use within restricted time windows of another triptan or ergotamine/ergot derivatives.
- Certain migraine types (e.g., basilar/hemiplegic) unless specialist-led.
- Allergy to zolmitriptan or tablet ingredients.
Interactions (Important)
- Other triptans and ergot medicines: do not combine within recommended washout periods.
- SSRIs/SNRIs and other serotonergic medicines: increased serotonin syndrome risk – clinician review required.
- Cimetidine and some CYP1A2 inhibitors (example: fluvoxamine, some quinolones): may require a lower maximum daily dose – clinician will advise.
- MAO inhibitors (or recent MAOI use): may be contraindicated depending on product prescriber will confirm.
Side Effects
Common
- Drowsiness or dizziness
- Warmth/tingling sensations
- Dry mouth
- Nausea
Serious Seek Urgent Medical Help
- Chest pain/tightness or pressure

Medication Overuse Headache (Important)
Using acute migraine medicines too often can lead to medication‑overuse headache. If you need triptans or other acute migraine medicines frequently, book a clinical review to discuss prevention options and safer use patterns.
