My daughter attempted suicide and took a whole bottle of 100 Tylenol 500mg during the course of an afternoon before calling for assistance. Other prescription meds were involved too. (But only a couple of weeks worth). She received an antidote for the Tylenol and is now in a sub acute environment receiving "other treatment". She has told me that she has not eaten in the past four days (very nauseous) and has had mucus and blood discharge from her rectum. Could this be a symptom of something caused by the Tylenol?
