1. WHAT IMIGRAN RADIS IS AND WHAT IT IS USED FOR
Each Imigran Radis tablet contains a single dose of sumatriptan, which
belongs to a group of medicines called triptans (also known as 5-HT1
Imigran Radis is used to treat migraine headache.
Migraine symptoms may be caused by the temporary widening of blood
vessels in the head. Imigran Radis 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.

methysergide (see section 2 Don’t use Imigran Radis). Don’t use Imigran
Radis at the same time as these medicines. Stop taking these medicines
at least 24 hours before using Imigran Radis. Don’t take any medicines
which contain ergotamine or compounds similar to ergotamine again for at
least 6 hours after using Imigran Radis.
