Hi thanks for contacting HCM.... If you have migraine attacks than rizatriptan like drug given ....And if still no improvement than repeat dose of that given .... You have given steroid that is used if neuritis like inflammation there . .. But as you have migraine, for migraine headache sumatriptan tablet you are mentioning can be taken ... Avoid precipitating factor for headache like. .... -Stress -bright light -loud noise -lack of sleep -skipped meal -smoking etc..... When headache take rest in dark and cool environment .... If repeated migraine attack comes amitryptillin prophylaxis can be given ... Consult neurophysician for proper examination ..... Take care.
