Quick Summary
- Fast-acting intranasal triptan for the acute treatment of migraine attacks (with or without aura).

- Prescription-only medicine (UK) – supplied after a clinical assessment where offered.
What is Imigran Nasal Spray?
Imigran nasal spray contains sumatriptan, a triptan medicine used to treat a migraine attack after it starts. The intranasal route can absorb quickly and may be easier to use if you feel sick during a migraine.
What Imigran Nasal Spray is Used For
- Short‑term (acute) treatment of migraine symptoms (headache, nausea, light/sound sensitivity).
- Migraine attacks with or without aura (when a clinician has confirmed your migraine diagnosis).
- Not for prevention – it does not stop future attacks from happening.
How It Works (Mechanism)
Sumatriptan targets migraine pathways by acting on specific serotonin (5‑HT1) receptors. This helps reverse migraine-related changes and reduces pain and associated symptoms during an active attack.
Why Choose the Nasal Spray (Buying Intent Benefits)
- Rapid absorption for quicker action for many people (response varies).
- Useful when nausea/vomiting makes swallowing tablets difficult.
- Portable single‑use applicator for convenient dosing during an attack.
Dose & How to Use (10mg Single‑Use Device)
| Strength | How to take | Repeat dose rules (typical) |
| Imigran nasal spray 10mg | Spray 1 dose into 1 nostril at the start of a migraine (as prescribed). | If symptoms return, a second dose may be used after at least 2 hours if advised. Do not exceed your prescribed maximum daily dose. |
Step-by-Step: How to Use the Nasal Spray
- Sit upright and keep your head level (not tilted back).
- Prepare/prime only if the Patient Information Leaflet (PIL) instructs you to.
- Insert the nozzle into one nostril and press once to deliver the dose.
- Breathe gently through your nose and keep your head upright for a few seconds.
- Dispose of the single‑use device after use.
Important Safety Rules
- Do not use within 24 hours of another triptan or ergot‑type migraine medicine.
- Do not take a second dose for the same attack if the first dose provided no relief (seek clinical advice).
- Avoid medication overuse: frequent use of migraine medicines can cause medication‑overuse headache – book a review if you need treatment often.

- History of heart disease or circulation problems (including angina/previous heart attack).
- Previous stroke or TIA.

Interactions (Important)
