Read the Patient Information Leaflet if available from your pharmacist before you start using sumatriptan spray and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Use this medication at the first sign of a migraine as directed by your doctor, usually 1 spray into one nostril. Avoid spraying into your eyes. Blow your nose gently before using this medication. Remove the protective cap, and block one nostril by pressing firmly on either side of your nose. Place the tip of the spray device into the other nostril and breathe in gently as you press the plunger. Keep your head upright, remove the tip from your nose, and breathe in gently through your nose and out through your mouth for 10 to 20 seconds. Your nose may feel wet inside and you may notice a slight taste after using the spray. This is normal.
If there is no improvement in your symptoms, do not take more doses of this medication before talking to your doctor. If your symptoms are only partly relieved, or if your headache comes back, you may use another dose at least two hours after the first dose. The dosage is based on your medical condition and response to treatment. Do not use more than 40 milligrams in a 24-hour period.
If you have a higher risk for heart problems (see Precautions), your doctor may perform a heart exam before you start taking sumatriptan. He/she may also direct you to take your first dose of this medication in the office/clinic to monitor for serious side effects (such as chest pain). Talk to your doctor for details.
Overuse of drugs to treat sudden migraine attacks can sometimes lead to worsening of headache (medication overuse headache) or rebound headache. Therefore, do not use this medication more often or for longer than prescribed. Tell your doctor if you need to use this medication more often, if the medication is not working as well, or if you have more frequent or worse headaches. Your doctor may need to change your medication and/or add another medication to help prevent headaches.
