sumatriptan side effects‼️‼️‼️‼️

Michelle

My husband just got a new medicine for his headaches and after 20 minutes or so he started to feel like he was about to pass out and had the cold sweats and just feels completely off. It didn’t help his headache either. Has anyone had any side effects like this on sumatriptan??????? HELP and yes we called his doctor we are just waiting to hear back
