Q Blacked out at work and almost fainted! This has never happened to me but im sick with a cough so i ate dinner (rice and chicken) and take antibiotic promethyzine for my cough, so im standing there bagging groceries and nxt thing u know im blacking out and was very close to fainting it was very scary, could this have been from the medicine? Ive taken it before and this has never happened.
Kindly note that, the symptom black out is one of the side effects of the drug promethazine. It can be seen, even if you have taken the drug earlier without any adverse effect. Also, note that, as you were sick, it might be due to the physical weakness also. You have to rule out the cause and for this just consult your physician, once.
