I woke up feeling a headache, I took a bc powder, the headache is turning into a migraine. I want to take my mjgraine med. (Rizatriptan 10 mg) but I've read ypu have to wait 5 hours after taking apsrin to take the rizatriptan. Has anyone evere taken the close together? Or k ow the reasons why they state waiting 5 hrs? I like to be safe while taking meds. or mixing them. Any info would be appreciated.
