ABOUT THIS MEDICATION

IPG-RIZATRIPTAN should not be used to relieve pain other than that associated with migraine headache.

IPG-RIZATRIPTAN should not be used within 24 hours of treatment with another 5- HT₁ agonist such as sumatriptan (Imitrex^*), naratriptan (Amerge^*) or zolmitriptan (Zomig^*), or ergotamine-type medications such as ergotamine, dihydroergotamine or methysergide.
