How do I properly use my sumatriptan nasal spray?

Hi,

Sumatriptan Nasal

To use the nasal spray, follow these steps:
Read all of the manufacturer's instructions for using the nasal spray before you use your first dose.
Blow your nose gently.
Remove the device from the blister pack.
Hold the sprayer between your fingers and thumb, but be careful not to press the plunger.
Use your other hand to block one nostril by pressing firmly on the side of your nose.
Put the tip of the sprayer into your other nostril as far as feels comfortable (about one half inch). Keep your head upright and close your mouth. If you are using Tosymra, tilt your head slightly back, and point the tip of the inserted sprayer toward the outside of your nose. Be careful not to press the plunger or spray the medication in your eyes.
Breathe in gently through your nose. At the same time, press the plunger firmly with your thumb.
Keep your head level and remove the tip from your nose.
Breathe gently in through your nose and out through your mouth for 10 to 20 seconds. Do not breathe in deeply. It is normal to feel liquid in your nose or the back of your throat.
The sprayer only contains one dose of medication. After you have used it, dispose of it safely, so that is out of the reach of children and pets.
