Rizatriptan or Maxalt is used to treat migraine headaches.
Rizatriptan or Maxalt is a "triptan" like zolmitriptan and sumatriptan and works in the same fashion - it constricts blood vessels in the cerebral or head area. It is thought that migraine headaches involve dilation of these blood vessels. These drugs may also reduce inflammation in the nerves that sense the pain of a migraine headache.
The most common side effects are drowsiness and dizziness. If sumatriptan or zolmitriptan does not agree with an individual, neither with Rizatriptan or Maxalt.
Rizatriptan or Maxalt can cause chest pain - like sumatriptan and zolmitriptan. Thus people with heart disease, prior heart attack, or even high blood pressure that is difficult to control should not use it because it may complicate their condition.
Rizatriptan or Maxalt should not be taken with either zolmitriptan or sumatriptan - they are the same type of drug. As with sumatriptan and zolmitriptan, Rizatriptan or Maxalt should not be used with ergotamine containing drugs or MAO inhibitor antidepressants.
