1. WHAT IMIGRAN NASAL SPRAY IS AND WHAT IT IS USED FOR
Each Imigran nasal spray contains a single dose of sumatriptan, which belongs to a group of
medicines called triptans (also known as 5-HT1 receptor agonists).
Pregnancy and breast-feeding
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.
