Took a sample of ubrelvy

I just got a sample from a doctor of Ubrelvy. I read some side effects like nausea but took it anyway because my head is in so much pain and figured I might as well try it sooner rather than later

Now, after about and hour and a half, I'm feeling super anxious. Mentally I haven't been the best but this feels super different because I have no cause for it like a usual anxiety attack.

I am starting to feel light headed and nauseous too. Is this a side effect or could it be something else? the pamphlet that came with it said it had some allergy symptoms like this but I'm unsure
