What is imigran nasal spray used for? 

Imigran is a sumatriptan nasal spray used to relieve symptoms of a migraine headache. It works by reducing the widening of blood vessels, which occurs during a migraine attack. Head pain, nausea or vomiting and sensitivity to light and sound can be treated with this medication.  

How to use imigran nasal spray 

You should only use Imigran nasal spray after your migraine headache begins and not use it as a method to prevent an attack. Before taking the medication, it is best to blow your nose if it feels blocked, or if you have a cold. Each spray contains just one dose of Imigran. 

How often can you take imigran nasal spray? 

You can use imigran nasal spray once a migraine headache begins. You should not use more than two sprays in 24 hours. If Imigran doesn’t give you any relief, you should speak to your doctor or pharmacist for advice.  

Imigran nasal spray dosage instructions

The usual dose for adults aged 18 to 65 is one Imigran 20 mg spray. For some people, imigran 10mg nasal spray is enough to treat their migraine.  

If your symptoms return after 2 hours of spraying your first dose, you can spray a second, but no more than 2 sprays in 24 hours. Using too much Imigran could make you unwell. You should speak to a doctor or pharmacist urgently If you use more than two sprays in 24 hours.
