What is Imigran Nasal Spray?

Each Imigran Nasal Spray contains a single dose of sumatriptan, which belongs to a group of medicines called triptans.

Imigran Nasal Spray is used to treat migraine headache. Migraine symptoms may be caused by the temporary widening of blood vessels in the head. Imigran nasal spray is believed to reduce the widening of these blood vessels. This in turn helps to take away the headache and relieve other symptoms of a migraine attack, such as feeling or being sick (nausea or vomiting) and sensitivity to light and sound.

How to take Imigran Nasal Spray

Don't open a blister until you are ready to use a spray. Each spray contains just one dose of Imigran. Don't press the plunger too soon or you will lose the dose.How to use the nasal spray

  • Remove the nasal spray from the blister packaging just before you want to use it.
  • Get into a comfortable position. You may prefer to sit down.
  • Blow your nose if it feels blocked, or if you have a cold.
  • Hold the nasal spray gently with your fingers and thumb.Don’t press the blue plunger yet.
  • Block one nostril by pressing a finger firmly on the side of your nose. It doesn’t matter which nostril you choose.
  • Put the nozzle of the nasal spray into the other nostril, as far as feels comfortable - about 1 cm or 1/2 inch. Breathe out gently through your mouth. Hold your head upright and close your mouth.
  • Start to breathe in gently through your nose. As you breathe in: Press the blue plunger firmly with your thumb. The plunger may feel a bit stiff and you may hear it click. Keep breathing in while spraying.
  • Remove the spray and remove your finger from the side of your nose. Keep your head upright for 10-20 seconds, breathing gently in through your nose and out through your mouth. This helps the medicine stay in your nose. Your nose may feel wet inside and you may notice a slight taste after using the spray -this is normal and will soon pass.
  • Your nasal spray is now empty. Throw it away safely and hygienically
