your girlfriend will be fine, I have neurocardiogenic syncope
and take metoprolol
, midodrine and fludrocortisone
. Syncope seems more serious than it actually is, the best thing you can do is be there for her because other peoples reactions to a fainter can be really hurtful, it's quite likely some smart ass will accuse her of attention seeking.
It may well be that your girlfriend will get better with just taking the metropolol but she might need some other pills as well, all syncope sufferers are different. You should ask her to take you along with her to an appointment so you can listen to what the specialists have to say and you can also find lots of info on syncope on the internet (but that's not the best source some say syncope is deadly but it really isn't).
