possibly a allergic reaction or maybe a med interference. i have never been able to get any over the counter migraine meds to work besides excederine tension and i was put on fioricet which helped. i would say a different ingredient whether inactive or active is in the off brand. nothing really compares to the original.
why do over the counter migraine medicine make my face swell. i used the kroger brand migraine medicine and it made my face swell. i haven't had a problem with any other headache medicine. i was just wondering what could cause this.
