Imigran Nasal Spray

Imigran Nasal Spray dosage & directions of use

Imigran Nasal Spray is effective when you take it once you notice your migraine attack has started. It will also be effective when taken later during a migraine attack. 

Imigran Nasal Spray is available in 10mg or 20mg doses. It is sprayed into one nostril. 

1. Imigran Nasal spray comes individually packaged in blister packs. Only open the blister pack once you are ready to use the spray.
2. If your nose feels blocked, blow it before you administer the medication
3. Hold the spray with your middle and index finger on either side of the nozzle. Your thumb will rest on the blue plunger
4. Then, insert the nozzle into one nostril (about 1 cm in) while blocking the other nostril by using a finger to apply firm pressure
5. Breathe in gently through your nose, and press the blue plunger firmly. Make sure that you are still breathing in while spraying the medication
6. Remove the nozzle and unblock your other nostril
7. Keep breathing in through your nose and out your mouth for the next 10 seconds. It is normal for your nose to feel wet and to taste a slight aftertaste after administering the spray

If the medicine is ineffective after taking a dose, wait at least 2 hours before taking a second dose of the nasal spray.
